The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) includes numerous alterations to specific disorders, as well as fundamental conceptual and organizational changes. The purpose of this article is to review three fundamental conceptual changes in DSM-5: the harmonization of the manual with the International Statistical Classification of Diseases and Related Health Problems, the introduction of spectrum disorders and dimensional ratings, and the new organization of the manual. For each change, potential benefits and shortcomings are discussed in terms of innovation, limitations and clinical implications.
Keywords: DSM-5, ICD-10, classification, diagnosis, spectrum disorders
The DSM is probably one of the most widely referenced texts in the mental health field. Considering this scope of influence, the release of its latest edition, DSM-5 (American Psychiatric Association [APA], 2013), has garnered considerable interest among professionals, patient advocacy groups and the public alike (Paris, 2013). Reactions have ranged from enthusiastic support (McCarron, 2013) to concern (Welch, Klassen, Borisova, & Clothier, 2013) and even calls to reject the manual’s use outright (Frances, 2013; Frances & Widiger; 2012). The strength of this reaction—both positive and negative—reflects the scope of change. DSM-5 attempts to integrate almost 20 years of burgeoning research in psychopathology, classification and treatment outcomes that have emerged since the publication of DSM-IV (APA, 1994), the last major revision of the manual’s criteria sets. While DSM-5 has made numerous alterations to specific disorders, fundamental conceptual and organizational changes have had the most substantial impact on reshaping the manual (APA, 2013; Regier, Kuhl, & Kupfer, 2013).
The purpose of this article is to review three of these fundamental conceptual changes: the harmonization of the manual with the ICD, the introduction of spectrum disorders and dimensional ratings, and the new organization of the manual. For each of these innovations, three questions will be addressed. First, what was the basis for introducing the change as an innovation to the manual? Here the rationale and potential contribution of the change will be discussed. Special attention will be paid to issues such as enhanced diagnostic accuracy, coverage and clinical utility. Second, does the innovation have any potential drawbacks or limitations? For example, to what extent could the innovation contribute to over or underdiagnosis, limit access to treatment, or pose some harm like increased stigmatization? Third, what are the practical consequences of the innovation relative to how clinical mental health counselors provide care for their clients? This section considers the impact on day-to-day practice and how the diagnostic process itself may be transformed. The conclusion section ties these three threads of innovations together and discusses implications for mental health practice in the 21st century.
DSM and ICD Harmony
There are two major classification systems for mental disorders: the DSM, used primarily in North America, and the ICD, used worldwide under the auspices of the World Health Organization (WHO). The ICD is a much broader classification encompassing causes of death, illness, injury and related health issues with one chapter dedicated to mental and behavioral disorders (Stein, Lund, & Nesse, 2013). As part of the United Nations Charter, countries around the world have agreed to use the ICD codes to report mortality, morbidity and other health information so that uniform statistics can be compiled. In the United States, the ICD codes are the official codes approved by the Health Insurance Portability and Accountability Act (HIPAA), which are used by insurance companies, Medicare, Medicaid and other health-related agencies (Goodheart, 2014). The code numbers that the DSM has always used are derived from whatever the official version of ICD is at that time. Currently, the ninth revision of the ICD (ICD-9; WHO, 1979) is the official coding system in the United States. The 10th revision of the ICD (ICD-10; WHO, 1992/2010) is scheduled to go into effect on October 1, 2015.
The DSM and ICD classifications of mental disorders have a number of similarities, but also have important differences. Both are descriptive classifications that categorize mental disorders based upon a constellation or syndrome of symptoms and signs. Symptoms are the client’s reports of personal experiences such as feeling sad, anxious or worried. Signs, on the other hand, are observable client behaviors such as crying, rapid speech, and flat affect. Structurally, both manuals group related mental disorders into either chapters (DSM) or diagnostic blocks (ICD). The names and diagnostic descriptions for many of the mental disorders in the ICD are similar to those in the DSM, a consequence of collaboration over the years and a shared empirical pool from which both have drawn.
Despite these similarities, there are significant disparities. First, DSM criteria are very specific and detailed, while the ICD relies more on prototype descriptions with less detailed criteria and minimal background information to guide the diagnostic process (First, 2009; Paris, 2013; Stein et al., 2013; WHO, 1992). Second, since DSM-III (APA, 1980), the DSM has used a multiaxial system that notes not only relevant mental and medical disorders, but also other diagnostic information such as environmental factors (Axis IV) and level of functioning (Axis V). The ICD, on the other hand, has always employed a nonaxial system that simply lists medical disorders, mental disorders, and other health conditions. These differences in complexity reflect the constituencies that each manual is designed to serve: The DSM is primarily used by licensed mental health professionals with advanced degrees, while the ICD needs to be accessible to a range of health care professionals worldwide with a broad range of educational backgrounds (Kupfer, Kuhl, & Wulsin, 2013; WHO, 1992).
A third discrepancy is that the names and descriptions for many disorders differ, which at times reflects marked conceptual differences (First, 2009). For example, in ICD-10 (WHO, 1992) bulimia nervosa has to be characterized by a “morbid dread of fatness” (p. 179), a concept akin to anorexia, while DSM-IV-TR (Text Revision; APA, 2000) requires that self-evaluation be “influenced” (p. 549) by only body shape or weight. As another example, the definition of the type of trauma that qualifies for post-traumatic stress disorder (PTSD) is much broader in ICD-10 (allowing for events that are exceptionally threatening or catastrophic) than in DSM-IV-TR (requiring that the event must be associated with actual or threatened death, serious injury, or threat to the physical integrity). These ICD-DSM disparities have led to difficulties comparing research results, collecting health statistics, communicating diagnostic information and reaching similar diagnostic decisions (APA, 2013; First, 2009; Widiger, 2005). Like conversing in two different languages, the diagnosis has often been lost in translation.
Innovation
From the outset of the DSM-5 development process there was a concerted effort to address these disparities. Joint meetings of representatives from APA and WHO met regularly throughout the process in an effort to make the manuals more compatible (APA, 2013; Regier et al., 2013). The goal was to find ways of harmonizing structural, conceptual and disorder-specific differences. The results of this process have had immediate effects on the look of DSM-5 and will have long-term effects on the harmonization of DSM-5 with the upcoming ICD-11, expected to be released in 2017 (APA, 2013; Goodheart, 2014).
The most significant impact of the harmonizing effort is the discontinuation of the multiaxial system in DSM-5. Axes I–III, the diagnostic axes (APA, 2000), are now collapsed into a nonaxial system, consistent with the ICD format. Psychosocial and environmental problems (formerly Axis IV) can be noted using ICD-10’s codes for problems and situations that influence health status or reasons for seeking care. These are usually referred to as Z codes and were formerly termed V codes in DSM-IV-TR. Axis V’s Global Assessment of Functioning (GAF) has been removed and replaced by an ICD measure for disability, the World Health Organization Disability Assessment Schedule (WHODAS) 2.0 (APA, 2013). Unlike the GAF, however, this rating is not required and serves only as an ancillary tool.
The following is an example of how a DSM-5 diagnosis might be listed using ICD-9’s nonaxial system in ICD-9:
296.42 Bipolar I disorder, current episode manic, moderate severity, with mixed features
307.83 Borderline personality disorder
V62.29 Other problem related to employment
The order of diagnoses would indicate that the bipolar disorder was the principal diagnosis and either the focus of treatment or reason for visit. In this example, borderline personality disorder is a secondary diagnosis. The V code is noted because it is an important area to target in the treatment plan.
There were three major reasons for abandoning the multiaxial system. First, health professionals in general medicine found it difficult to use because it was so different from the ICD format (Kupfer et al., 2013). Second, the multiaxial system contributed to the idea that mental disorders were qualitatively different from medical disorders, a dated dualistic distinction between mind and body (APA, 2013; Kupfer et al., 2013; Lilienfeld, Smith, & Watts, 2013). Third, research had shown that distinctions between Axes I and II were artificial and did not reflect that these axes actually overlapped considerably (Lilienfeld et al., 2013). Thus, the multiaxial system seemed to create artificial distinctions that did not seem valid (Lilienfeld et al., 2013). The ICD, on the other hand, offered a more simplified system that allowed a diverse group of health professionals to code disorders using a similar format.
Substantial harmonization of the manuals, however, will happen in the future. Not much could be done with harmonizing ICD-10 (WHO, 1992), a manual of the DSM-IV (APA, 1994) era, the organization and conceptual framework of which were well established (APA, 2013; Goodheart, 2014). The forthcoming ICD-11 will adopt much of DSM-5’s organizational restructuring (discussed below) and include a number of the new DSM-5 disorders (APA, 2013; Goodheart, 2014).
Limitations
Despite the potential contribution of this harmonization, there are three major drawbacks to consider. First, the loss of the multiaxial system may compromise the richness of the diagnostic assessment. In a sense, the multiaxial system was holistic in that it provided a way of noting prominent psychiatric conditions, maladaptive personality functioning, medical conditions, relevant stressors and environmental problems, and overall functioning. What will prompt clinicians to consider these important domains remains unclear. Noting V codes and assessing disability using the WHODAS 2.0 may be an alternative. However, these tasks are not required in the diagnostic workup and, if history is any guide, will probably be underutilized.
A second consideration is that consilience with the ICD clearly makes the DSM-5 a “medical classification” (APA, 2013, p. 10) and as David Kupfer, the Task Force Chair of DSM-5, has put it, “psychiatric disorders are medical disorders” (Kupfer et al., 2013, p. 388). The DSM espouses that it is atheoretical (APA, 2013; Lilienfeld et al., 2013), but the momentum is clearly swinging toward the central role of biological factors. This risks a reductionistic conceptualization of mind as simply brain. Alternative perspectives that recognize the importance of contextual, psychological, developmental and cultural factors, fundamental to the mental health counseling tradition (Gintner & Mears, 2009), may suffer as a result. The picture is more ominous considering the National Institute of Mental Health’s initiative, Research Domain Criteria (RDoC), designed to develop the next generation of psychiatric classification based upon underlying etiology of “brain disorders” (p. 749) and the identification of biomarkers (e.g., laboratory tests) to direct treatment selection (Insel et al., 2010). The direction in which the diagnostic train is heading is clear. The question is whether the track can be altered to one that is more balanced and biopsychosocial.
A third concern is that efforts to harmonize the manuals do not address many of the disparities between DSM-5 and ICD-9 or ICD-10. This is particularly true of the new disorders that DSM-5 has added, which lack clear ICD-9 or ICD-10 counterparts. The ICD codes that have been selected often do not map well onto these disorders. For example, the code for DSM-5’s hoarding disorder translates to ICD-9’s and ICD-10’s obsessive-compulsive disorder (OCD). Ironically, hoarding disorder was added because research showed that 80% of the time individuals with this condition did not meet criteria for OCD. As another example, binge eating disorder was added to DSM-5 to recognize individuals who had a pattern of maladaptive bingeing episodes, but did not have the compensatory behaviors (e.g., purging) characteristic of bulimia nervosa. The ICD code selected for this disorder was, nevertheless, bulimia nervosa. Because ICD is updated annually, it may be that more appropriate codes will be made available in future years. Thus, while ICD-DSM consilience has occurred, at least to this point, it has been superficial and restricted to the nonaxial formatting of the diagnosis. Clearly, it may enhance the curb appeal of DSM-5 to the medical community, but the real interior renovation is yet to occur, awaiting ICD-11.
Clinical Implications
The demise of the multiaxial system means that mental health counselors must be more intentionally biopsychosocial in their diagnostic assessments. More meat can be put on the bare-bones nonaxial system by systematically assessing these biological, psychological and sociocultural factors. This can be accomplished by always assessing whether any important contextual factors can be noted using the V codes, which will be termed Z codes when ICD-10 goes into effect. The WHODAS 2.0, the retired GAF, and other functioning measures can be recruited to assess impairment. While these measures are not part of the formal diagnosis, they can be noted in the chart and inform treatment planning.
Many insurance companies require a multiaxial diagnosis. The GAF score was often used to justify level of care. At the time of this writing, it is not clear what insurance companies will do with these modifications. The decision here will be important. What insurance companies require, for better or worse, often has profound impact on what clinicians do and the kind of clinical care they deliver.
Spectrum Disorders and Dimensionality
Both the DSM and ICD classify mental disorders into discrete categories. Clinicians make a yes-no decision about whether or not an individual has a disorder, based upon the particular criteria. But it has long been known that this categorical approach is fraught with problems (First & Westen, 2007; Widiger, 2005). First, comorbidity is common and there is some question as to whether comorbid conditions such as depression and anxiety are distinct or are really different expressions of some shared underlying dysfunction (Lilienfeld et al., 2013). Second, clinicians have used the not otherwise specified (NOS) category 30–50% of the time, indicating that a sizable proportion of phenomena have a varied presentation that existing categories do not capture (Widiger, 2005). This is problematic because NOS is not particularly informative in terms of describing the condition or making decisions about treatments. Finally, a categorical system assumes that each disorder is homogenous and that disorder occurs at the particular cut point. There is no recognition of subthreshold symptoms, and there is the assumption that those who do fulfill the criteria are qualitatively similar. This view is at odds with data showing that symptoms vary considerably in terms of severity and accompanying features (First & Tasman, 2004). In this sense, categorical assignment loses potentially useful clinical information about the condition and about what treatment strategies might be indicated.
Innovation
DSM-5 attempts to address this issue by introducing dimensionality to supplement the categorical approach (APA, 2013). While categories indicate differences in kind, dimensions describe variations in degree (Lilienfeld et al., 2013). From this perspective, mental disorders are considered to lie on a continuum, like blood pressure. Theoretically, the spectrum can run from optimal functioning to significant impairment. Markers of morbidity or adverse outcome determine where on the spectrum the cut point for disorder is drawn. In the case of blood pressure, for example, it is 140/90. This dimensionality allows for more fine-grained determination of not only severity or impairment, but also improvement or deterioration. Over the past 30 years, research has shown that many mental disorders appear to be more dimensional and heterogeneous than suggested by ICD’s or DSM’s purely categorical system (First & Westen, 2007; Helzer, 2011; Paris, 2013).
Dimensionality is incorporated into DSM-5 in three general ways. First, DSM-5 has added several formal spectrum disorders, which combine highly related disorders. Autism spectrum disorder merges together DSM-IV-TR’s autism disorder, Asperger’s disorder, childhood disintegrative disorder and pervasive developmental disorder NOS. Research has shown that these four conditions share many common symptoms, and the differences are more a matter of degree (APA, 2013; Tsai & Ghaziuddin, 2014). Another spectrum disorder is substance use disorder, which blends the former categories of abuse and dependence. The somatic spectrum is captured by somatic symptoms disorder, which merges what was formerly somatization disorder, pain disorder and undifferentiated somatoform disorder. For each of these spectrum disorders, DSM-5 provides a severity rating as well as other specifiers to note degree of impairment and complicating features.
A second way that dimensionality is infused into DSM-5 is that severity ratings and an expanded list of specifiers have been placed within the existing categories. In a sense, DSM-5 tries to dimensionalize the category. While this was done to some extent in previous editions, DSM-5 broadens this effort throughout the manual. For example, a number of new specifiers were added to describe mood episodes such as anxious distress (presence of comorbid anxiety), mixed features (presence of symptoms from the opposite mood pole), and peripartum onset (onset of symptoms sometime during pregnancy through one month post-delivery). The addition of these notations can be helpful in making treatment-planning decisions (First & Tasman, 2004). For example, severity ratings are an important consideration in deciding whether to use psychotherapy or medication for the treatment of major depressive disorder (APA, 2010). Feature specifiers like anxious distress and mixed features have been shown to increase suicide risk and portend a more complicated treatment regime (APA, 2013; Vieta & Valentí, 2013).
A third way that dimensionality is being promoted in DSM-5 is through the availability of a variety of online assessment measures (APA, 2014). These are rating scales that fall into three general categories. First, there are disorder-specific measures that correspond closely to the diagnostic criteria. These measures could be used to buttress the more clinical assessment that relies on the diagnostic criteria. They could also provide a means of assessing the client’s baseline and response to treatment over time. Measures are available for a range of disorders including depression, many of the anxiety disorders, PTSD, acute stress disorder and dissociative symptoms. Versions are available for adults as well as children aged 11–17. Most of these are self-completed but some are clinician-rated. A second type of measure is the WHODAS 2.0, discussed earlier, which assesses domains of disability in adults 18 and older. A third type of measure is referred to as cross-cutting symptom measures (CCSM). Similar to a broadband assessment of bodily systems in medicine, these measures assess common psychiatric symptoms that may present across diagnostic boundaries and may be clinically significant to note in the overall treatment plan. Level 1 CCSM is a brief survey of 13 domains of symptoms (e.g., depression, anxiety, psychosis, obsessions, mania). A more in-depth Level 2 assessment measure is available for a domain that indicates a significantly high rating. These measures can be reproduced and used freely by researchers and clinicians and can be downloaded at http://www.psychiatry.org/practice/dsm/dsm5/online-assessment-measures. Use of these types of measure is hoped to add surplus information that can aid diagnosis, case monitoring and treatment planning.
Limitations
Dimensions are not only intuitively appealing, but also seem to be a better reflection of nature (Lilienfeld et al., 2013). Notwithstanding, serious concerns have been raised. First, determining the appropriate cut point on these dimensions is critical in terms of determining true psychopathology. If the bar is set too low, there is a danger of pathologizing normal behavior. If set too high, those who need treatment may be excluded and denied services. At this point, data suggest that at least for autism spectrum disorder and substance use disorder, the bar might be set too high. For both, DSM-5 criteria tend to miss people on the more benign end of the spectrum. For example, those who formerly might have been diagnosed with mild to moderate Asperger’s, pervasive developmental disorder NOS, or substance abuse may no longer qualify for a diagnosis (Beighley et al., 2013; Mayes, Black, & Tierney, 2013; Peer et al., 2013; Proctor, Kopak, & Hoffmann, 2013). On the other hand, Frances (2013) has suggested that the threshold for somatic symptoms disorder is set too low, pathologizing many with normal worry about their medical illnesses.
A second concern is that lumping mild and more severe disorders into a unitary spectrum disorder can have unintended social effects, especially for people on the more benign end of the spectrum. For example, those who formerly were diagnosed with Asperger’s disorder will now be labeled with autism spectrum disorder. A college student who was diagnosed with alcohol abuse using DSM-IV-TR criteria will now carry the same diagnosis as someone who is considered an alcoholic and dependent (Frances, 2013). One unanswered question is the impact of these types of name changes on perceived stigma and consequent help seeking.
A final concern is that the dimensional measures were released prematurely without adequate testing and without sufficient guidelines for their use (Jones, 2012; Paris, 2013). While some of the measures are well established (e.g., Patient Health Questionnaire [PHQ]-9; APA, 2014), others have little to no psychometric support (e.g., Clinician-Rated Severity of Autism Spectrum and Social Communication Disorders). Scoring guidelines are made available, but information about the measure’s psychometric properties and norming are lacking. There also is no information on who is qualified to use these measures and what type of training they should have. Thus, while dimensionality may be an important innovation in the development of the DSM classification system, there are significant challenges ahead in calibrating these dimensions, refining the measures and considering social consequences.
Clinical Implications
Will dimensionality help or hinder the diagnostic process? On one level, the additional information about the condition may shift counselors’ fundamental way of thinking about treatment from “curing” clients (dichotomous) to helping them move toward more optimal points on the spectrum (dimensional). The availability of dimensional measures has the potential of improving diagnostic accuracy and providing a measure of treatment outcome (Segal & Coolidge, 2007). It may open the door to more measurement-based care, in which these ratings can be used to assess more precisely the need for care and the extent to which clients are profiting from treatment. This process may be more feasible to administer, score and record if these measures can be stored on tablets or mobile applications.
In terms of using these dimensional measures, however, the unanswered question is—at what cost? Clinicians are already busy, and anything that encumbers that process even more will be resisted (Paris, 2013). Criteria sets are now a bit more complex to navigate because of the added severity rating and feature specifiers. It will take considerable time to learn and master the range of measures that have been posted online, much less research their psychometric appropriateness for the situations in which they will be used. The wild card is whether managed care will require these types of measures as a way of documenting need for treatment and response to provided services. At this point, clinicians would be best served to proceed cautiously, ensuring that the measures they use are reliable and valid for the client population intended.
The New Organization of DSM-5
How was it decided in previous editions of the DSM which chapters to include and which disorders to place in each of them? While some research guided this process, tradition and clinical consensus were the primary sources that informed the organization of these earlier manuals (First & Tasman, 2004; Regier et al., 2013; Widiger, 2005). DSM-5 took a radically different approach, drawing upon research that examined how disorders actually cluster together. In this section, the new framework is examined and potential benefits and costs discussed.
Innovation
The DSM-5 manual is divided into three major sections. Section I provides an introduction, a discussion of key concepts such as the definition of a mental disorder, and guidelines for recording a diagnosis. Section II is the meat of the manual and contains all the mental disorders and other conditions that can be coded with their diagnostic criteria and background information. Section III includes tools for enhancing the diagnostic process, such as some of the dimensional measures discussed earlier, the WHODAS 2.0, and a Cultural Formulation Interview designed to assess the impact of culture on the clinical presentation. This section also includes a list of proposed mental disorders that require further study (e.g., Internet gaming disorder) and an alternative system for diagnosing personality disorders.
Table 1 lists DSM-5’s major categories (chapters) of mental disorders. Two general principles determined the sequence of chapters and the placement of disorders within chapters. First, disorders were grouped into similar clusters based upon shared underlying vulnerabilities, risk factors, symptoms presentation, course and response to treatment (APA, 2013). Groups that are positioned next to each other share more commonalities than those placed further apart. For example, bipolar disorder follows schizophrenia spectrum because they share a number of vulnerability factors (APA, 2013). Next to bipolar disorder is the chapter on depressive disorders. However, the sequence of chapters indicates that depressive disorders are more distantly related to schizophrenia spectrum. Next, internalizing disorders characterized by depression, anxiety and somatic symptoms are listed in adjacent chapters because of common risk factors, treatment response and comorbidity (APA, 2013). Externalizing disorders, noted by their impulsivity, acting out and substance use, are placed in the latter part of the manual.

Other Conditions That May Be a Focus of Clinical Attention |
This shared commonality principle is also evident in the placement of disorders within chapters. As a result, a number of disorders have been transferred to different chapters. For example, DSM-IV-TR’s chapter on sexual and gender identity disorders contained sexual dysfunctions (e.g., premature ejaculation), paraphilias (e.g., exhibitionism) and gender identity disorder. Research showed that these three were not highly related, so they have been moved into different chapters, each of which is more proximally located to related disorders (APA, 2013). As another example, DSM-IV-TR’s anxiety disorders chapter has been divided into three separate chapters: anxiety disorders that are more fear-based (e.g. phobias); obsessive-compulsive and related disorders, which are characterized by preoccupations and repetitive behaviors (e.g., body dysmorphic disorder); and trauma- and stressor-related disorders. The latter is akin to a stress-response spectrum that ranges from severe reactions like PTSD to milder reactions characteristic of an adjustment disorder. It is hoped that these organizational changes will help clinicians locate disorders as well as identify related comorbidities (APA, 2013).
A second organizational principle is that the DSM-5 framework reflects a life-span perspective, both across and within chapters. Neurodevelopmental disorders (e.g., autism spectrum disorder, attention-deficit/ hyperactivity disorder [ADHD]) are listed first because they typically emerge early in life. Schizophrenia spectrum disorders also frequently have antecedents that manifest themselves in childhood (APA, 2013). Next are disorders that usually appear in adolescence and early adulthood, such as bipolar disorders, depressive disorders and anxiety disorders. In the middle and back of the manual are disorders that emerge in adulthood or late adulthood, such as personality disorders and neurocognitive disorders (e.g., dementia related to Alzheimer’s disease).
A developmental perspective also is infused into the organization of each chapter. DSM-IV-TR’s chapter on disorders of infancy, childhood and adolescence has been eliminated, and these disorders have been redistributed throughout the manual into relevant chapters. Each chapter is developmentally organized with disorders that emerge in childhood listed first, followed by those that appear in adolescence and adulthood. For example, oppositional defiant disorder and conduct disorder have been moved to the beginning of the chapter on disruptive, impulse control and conduct disorders. In addition, the criteria sets now include developmental manifestations of symptoms. For example, the ADHD criteria set includes both child and adult examples of the various symptoms. There also is an expanded section on development and course for each of the disorders, which explains how symptoms typically unfold over the life span. It is hoped that these types of changes will help clinicians recognize age-related manifestations of symptomatology (Kupfer et al., 2013; Pine et al., 2011).
The intent of the DSM-5 initiative was to develop a more valid organizational structure grounded in research. In the end it also may help to uncover common etiological factors—the holy grail of classification efforts (Insel et al., 2010; Stein et al., 2013). Certainly, these changes will help with differential diagnosis. The organization provides a better map of the relationship between disorders and how the diagnostic landscape may change over the life span.
Limitations
The new organization of the DSM-5 has been generally well received (Stein et al., 2013). One major concern that has been raised, however, is the decision to dismantle the chapter on child and adolescent disorders (Pine et al., 2011). Now there is not one place where the range of childhood disorders is listed. The neurodevelopment disorders—the remnant of the former child and adolescent chapter—is largely limited to disorders that manifest with early developmental delays and problems with language, learning, motor behavior, thinking or attention. Missing, however, are a broader range of behavior problems and anxiety disorders that the former chapter included. The problem is that many of these disorders can co-occur. For example, about 30–50% of children with conduct disorder have a specific learning disorder (Gintner, 2000). The wide separation of conditions such as these in the manual may interfere with accurate detection, especially among those who are not familiar with child and adolescent disorders.
Clinical Implications
Mental health counselors have a new organization to master. Anecdotally, probably one of the most common comments I hear about the new manual is, “Where do I find X now?” Understanding the new organization of the manual will require more than simply looking over the new structure. It will be critical to read the manual to understand why disorders were grouped in a particular chapter. Chapters that are either newly introduced in the manual or that were significantly altered will certainly need to be carefully reviewed. These include the chapters on neurodevelopmental disorders, obsessive-compulsive and related disorders, trauma- and stressor-related disorders, substance-related and addictive disorders, and neurocognitive disorders.
Importantly, the new DSM-5 message is that the structure is designed to indicate relationships within chapters and between chapters. This is a different way of thinking diagnostically. For example, in considering possible diagnostic alternatives, the clinician can first ask this broad question: Is this on the internalizing or externalizing spectrum? If the condition seems more internalizing, then the possible chapters have been winnowed down, and progressively more specific questions can be asked to locate the disorder in the particular chapter. The organization also alerts the diagnostician that adjacent chapters may hold comorbid conditions or even unexplained subthreshold symptoms. To take advantage of this diagnostic aid, however, it will be critical for mental health counselors to learn their way around this new framework.
Conclusions
These conceptual changes define the new look of DSM-5. ICD’s consilience, dimensionality and the organizational restructuring have fundamentally transformed DSM-5 into a 21st-century document that reflects the current state of knowledge in the mental health profession. The good news is that these changes may make the manual a better reflection of nature (i.e., research has shown it to be more valid) compared to previous editions. As a result, the way counselors diagnose and how they think about mental disorders is changing. Hopefully, such change will not only result in better care, but will also help researchers identify the deeper etiological substrates of mental disorders.
In science, progress also can have a dark side. While the DSM-5 incorporates the latest research, the entire development process and critical review highlight the primitive state of knowledge in the profession. While the spectrums and dimensions will no doubt transform the way mental health professionals diagnose, at this point they are crude and may help certain client populations, but hurt others. Harmonization with the ICD will probably take the DSM-5 to a broader audience of health providers. But it also further medicalizes the DSM-5 and will steer it perilously close to a biologically-based classification system. It will be up to mental health counselors and allied mental health professionals to help correct the course and find the middle way exemplified in the biopsychosocial model. Until then, DSM-5’s advances will be tempered by these potential limitations.

With the advent of the DSM-5 in 2013, the American Psychiatric Association eliminated the longstanding multiaxial system for mental disorders. The removal of the multiaxial system has implications for counselors’ diagnostic practices. In this article, the removal of the multiaxial system in the DSM-5 is discussed, and counselor practice suggestions related to each of the five Axes are provided. Additionally, ways in which counselors can sustain their current diagnostic skills while developing updated practices that align with the new streamlined system will be discussed.
Keywords: DSM-5, multiaxial system, diagnostic skills, mental disorders
The American Psychiatric Association (APA) developed the original Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1952 to create a uniform way to define mental health disorders. At the time, the manual contained narrative, psychodynamic descriptions regarding psychiatric disorders. Fueled by criticism regarding questionable foundations and lack of discrete diagnostic criteria, APA engaged in a comprehensive overhaul of the diagnostic system in preparation for the third edition of the manual (First, 2010). In 1980, the APA released the radically different DSM-III, a categorical nosological system with presumably atheoretical foundations and a multiaxial assessment system that ensured attention to biological, psychological and social elements related to mental disorders.
Although paradigm shifts were not as comprehensive as some might have hoped (First, 2010; Kupfer & Reiger, 2011), the most recent revision process resulted in the DSM-5 (APA, 2013) and the first major structural changes to diagnostic classifications and procedures since the DSM-III (APA, 1980). Key DSM-5 changes included reorganization of disorders into new categories on the basis of presumed etiological characteristics, movement toward dimensional conceptualization of disorders and discontinuation of the multiaxial system (Dailey, Gill, Karl, & Barrio Minton, 2014). Some revisions, such as a trend toward lower diagnostic thresholds (Frances, 2013; Miller & Prosek, 2013) and incorporation of complex, unvalidated assessment tools (First, 2010; Jones, 2012) received a great deal of public attention and comment. In contrast, removal of the multiaxial system happened quietly and with very little scholarly or public comment (Probst, 2014).
In this article, the title DSM will be used to refer to historic versions of the Diagnostic and Statistical Manual of Mental Disorders. References to specific editions will be clearly indicated with numerals or numbers in addition to the title. First, we provide a brief overview of the DSM and its use by counselors. Next, we describe the longstanding multiaxial system and discuss arguments in favor of and against removal of the multiaxial system. Throughout, we discuss implications for counselor diagnosis and practice.
Counselors’ Use of the DSM
In order to understand the implications of the elimination of the multiaxial system, professional counselors must possess a preliminary understanding of the complex relationship between professional counseling and the DSM. Over time, the more general DSM system has come under critical review, especially by counselors who question how the diagnostic process fits with our professional identity and ethical obligations (Eriksen & Kress, 2006; Kress, Hoffman, & Eriksen, 2010; Zalaquett, Fuerth, Stein, Ivey, & Ivey, 2008). Eriksen and Kress (2005) detailed commonly cited limitations of the DSM and how it is used:
- Historically, some diagnostic labels have marginalized, stigmatized and harmed those who are different from the mainstream (e.g., homosexuality was once a DSM diagnosis).
- There is limited evidence of cross-cultural validity in diagnostic conceptualizations.
- Counselors who focus narrowly on diagnosis may only look for behaviors that fit within a medical or biological understanding of the person’s struggles (i.e., becoming reductionistic).
- The DSM system does not include sufficient emphasis on contextual factors (e.g., developmental struggles and transitions, culture, gender), strengths, resources, and uniqueness that may better explain the roots of client struggles and treatment implications.
- The DSM system cannot predict treatment outcomes or point to the etiology of mental disorders.
- Some people may use diagnosis to accept a self-fulfilling prophecy that their situation is hopeless and that they are sick.
- Diagnosing may preclude a focus on the client’s unique construction of his or her experience.
- There are flaws in the science behind DSM diagnoses; what is and is not classified as a mental disorder is often rooted in a political agenda and historical influences.
Limitations of the DSM require that counselors use it carefully, and thoughtfully consider challenges related to its use. Although Eriksen and Kress (2005) wrote in reference to the DSM-IV-TR, underlying assumptions and broad-based diagnostic processes have not changed in the DSM-5 (APA, 2013). We expect that these limitations will continue to be relevant to counselors.
In contrast to the reductionistic, medically oriented diagnostic model inherent within the DSM system (Eriksen & Kress, 2005), counselors emphasize strength-based and developmentally, culturally and contextually sensitive approaches (Kress & Paylo, 2014). Despite the best efforts of many counselors to establish and promote a professional identity that is distinct from other mental health professions, market demands frequently dictate aspects of clinical practice (Eriksen & Kress, 2006). Counselors are licensure-eligible in all 50 states and regularly recognized on insurance panels; as such, there is an expectation that mental health counselors will use the DSM for third-party reimbursement (Kress & Paylo, 2014). Thus, counselors may find themselves working to balance unique professional identities with realities of a diagnostic system created by and for physicians who have a primary focus on pathology.
Despite its limitations, the DSM system is useful in a number of ways (APA, 2013; Dailey et al., 2014; Eriksen & Kress, 2005, 2006; Kress & Paylo, 2014). Primarily, it serves as a way of communicating about client problems and struggles. Assuming that all client-related information is considered, it offers a vehicle for reducing complex information into a manageable form (Kress & Paylo, 2014). Through the categorization of psychological symptoms into disorders, the DSM system provides a means for counselors to select evidence-based treatments that correspond to said disorder. Some clients may benefit from receiving a diagnosis as it may help them to normalize and understand their experiences, sometimes even helping them to reduce the shame and self-blame that often relate to symptoms (Eriksen & Kress, 2005). Finally, categorization and identification of disorders allows researchers to study the etiology and treatment of various mental disorders. Such a process lends itself well to the development of prevention, early intervention and effective treatment measures that have very real impacts on clients’ lives (APA, 2013). The DSM-5 (APA, 2013) also provides systematic information about diagnostic features, associated features supporting diagnosis, subtypes and/or specifiers, prevalence, development and course, risk and prognostic factors, diagnostic measures, functional consequences, culture-related diagnostic issues of each diagnosis; this information may be helpful to counselors who are struggling to fully understand their clients’ experiences.
An understanding of clients’ contextual experience is essential for conceptualizing client concerns and planning counseling strategies that are relevant to clients and have a strong probability of success (Kress & Paylo, 2014). In the past, those who engaged in multiaxial diagnosis were cued to at least consider biopsychosocial elements of clients’ concerns, including mental disorders, medical conditions, psychosocial and environmental stressors, and overall functioning. In the following section, we attend to the rise and fall of the multiaxial system.
Rise and Fall of the Multiaxial System
The APA first introduced the multiaxial system in the DSM-III (1980). A radical departure from the previous version of the document, the DSM-III introduced categorical, symptom-based diagnosis (First, 2010). In attempts to ensure clinical utility of information reported, the authors suggested, but did not require, that clinicians report diagnostic information on five distinct Axes. This tradition continued with only modest changes in the DSM-IV (APA, 1994) and DSM-IV-TR (APA, 2000).
The DSM-IV-TR (APA, 2000) multiaxial system involved documentation of diagnosis on five Axes. Axis I listed the primary or principal diagnoses that needed immediate attention; this included recording of clinical disorders as well as “Other Conditions That May Be a Focus of Clinical Attention” (e.g., life stressors, impairments in functioning; APA, 2000, p. 27). Axis II contained pervasive psychological issues such as personality disorders, personality traits and mental retardation (now intellectual disability disorder) that shaped responses to Axis I disorders. Axis III was intended to cue reporting of medical or neurological problems that were relevant to the individual’s current or past psychiatric problems. Axis IV required clinicians to indicate which of nine categories of psychosocial or environmental stressors influenced client conceptualization or care (e.g., recent divorce, death of partner, job loss). Finally, Axis V included the opportunity to provide a Global Assessment of Functioning (GAF) rating, a number between 0 and 100 intended to indicate overall level of distress or impairment.
Introduction of the multiaxial system was never without controversy or difficulty (Probst, 2014). Specific concerns included the degree to which Axes I and II were mutually exclusive and distinct (Røysamb et al., 2011), lack of clear boundaries between medical and mental health disorders (APA, 2013), inconsistent use of Axis IV for clinical and research purposes (Probst, 2014), and poor psychometric properties and clinical utility of the GAF (Aas, 2010; APA, 2013). Those most closely associated with APA noted concern that the multiaxial system was rarely used to its full potential and lacked clinical utility (APA, 2013; First, 2010). In 2004, APA first entertained a motion to explore elimination of the multiaxial system unless evidence was presented to suggest that the system enhanced patient care (First, 2010; Probst, 2014). Upon reviewing the literature, a 2005 committee recommended maintaining the system in the next iteration of the DSM and suggested that APA provide resources to support more widespread and consistent use (Probst, 2014). Nearly eight years later, the APA discontinued use of the multiaxial system, seemingly without public discussion or comment. Indeed, APA included just three paragraphs regarding this shift in the DSM-5, noting that “despite widespread use and its adoption by certain insurance and governmental agencies, the multiaxial system in DSM-IV was not required to make a mental disorder diagnosis” (2013, p. 16).
From Multiaxial to Nonaxial Assessment
Clinicians who are accustomed to documenting diagnosis using a multiaxial system may wonder what DSM-5 assessment and diagnosis will look like. APA provided little concrete guidance, stating, “DSM-5 has moved to a nonaxial documentation of diagnosis (formerly Axes I, II and III), with separate notations for important psychosocial and contextual factors (formerly Axis IV) and disability (formerly Axis V)” (2013, p. 16). In the following sections, we explore evidence related to the shift and identify implications for counselors.
Medical and Mental Health Conditions (Axes I, II and III)
Axes I, II and III have been eliminated in the DSM-5 (APA, 2013). Clinicians can simply list any disorders or conditions previously coded on these three Axes together and in order of clinical priority or focus (APA, 2013). Because many billing systems already used this system, this may not result in meaningful changes in terms of third-party billing.
This change removes the distinction of previous clinical disorders, personality disorders and intellectual disability disorder. Over time, clinicians have questioned whether Axis II personality disorders were qualitatively different from or any more stable than Axis I clinical disorders (Røysamb et al., 2011); one might also argue that certain developmental disorders (e.g., autism spectrum disorder, previously coded on Axis I) are just as longstanding and pervasive as intellectual disability disorder. Although there is some evidence that personality disorders are distinct from other clinical disorders, emerging evidence indicates that mental disorders do not factor cleanly into these classifications (Røysamb et al., 2011). It is possible that this subtle shift in coding may decrease the stigma often associated with personality disorders.
At the same time, this change in coding suggests that there is no differentiation between medical conditions and mental health disorders. Initially, APA released a definition in which it conceptualized mental disorders as “a behavioral or psychological syndrome or pattern that occurs in an individual” and “reflects an underlying psychobiological dysfunction [emphasis added]” (APA, 2012). The resulting controversy and dialogue regarding lack of evidence for the claim led to a more balanced definition of mental disorder as involving “a dysfunction in the psychological, biological, or developmental processes underlying mental functioning” (APA, 2013, p. 20). Still, clinicians will find that the previous DSM-IV-TR phrase “general medical condition” has been replaced with “another medical condition” throughout the DSM-5 (e.g., APA, 2013, p. 161). Together, these reinforce an assumption that mental disorders are rooted in biological causes.
Some have suggested that an increased emphasis on mental disorders as organic implies that environmental factors are less important, and this could reduce the stigma that many people with mental disorders feel (Yang, Wonpat-Borja, Opler, & Corcoran, 2010). Certainly, the DSM-5 (APA, 2013) includes evidence that some mental disorders have considerable genetic and neurological links, even if scientists have yet to identify clear laboratory markers for any DSM diagnosis (First, 2010). However, others have suggested that this approach could reinforce the notion that those with mental disorders are biologically flawed as opposed to being complex beings who traverse many complicated contextual factors that impact their functioning (Ben-Zeev, Young, & Corrigan, 2010).
This shift toward viewing mental disorders from a neurobiologically based perspective may result in increased use of psychopharmacotherapy, or medication therapy (Frances, 2013). Although many clients may benefit from or require psychotropic medications to function effectively, others with mental disorders do not require this type of intervention. The use of medications can invite serious side effects and financial costs and preclude participation in psychosocial therapies demonstrated to be successful in long-term management of many mental disorders. Counselors should be mindful of these changes as they advocate at the community, state and national levels to ensure clients are educated about medication options, understand effectiveness of psychosocial and counseling treatments, and have access to appropriate care (Dailey et al., 2014).
Even if somewhat arbitrary, removing the distinction between mental disorders and medical disorders has the potential of creating confusion within the helping professions as to the nature of the treatment provided. Counselors may struggle regarding their role in recording medical diagnoses that they are not qualified to diagnose, and should collaborate with medical professionals to offer a holistic treatment conceptualization. Counselors would do well to consider the body of evidence regarding etiology of mental disorders and evaluate ways in which they may make unique contributions to client change.
Psychosocial and Contextual Factors (Axis IV)
Clinicians previously listed psychosocial and contextual factors that affect clients and are relevant to conceptualization on Axis IV:
Originally conceived in the third edition of the diagnostic manual as a way to rate and rank the severity of particular stressors, axis IV was simplified for the fourth edition because of the difficulty in reliably quantifying the etiologic contribution of specific stressors to mental disorder; instead, clinicians were asked to simply note salient environmental factors. (Probst, 2014, p. 123)
This included notation regarding concerns in nine key areas: primary support group, social environment, education, occupation, housing, economic, access to health care, legal system/crime and other (APA, 2000).
Although information listed on Axis IV was intended to supplement diagnoses on the first two Axes, clients who attended counseling for only an Axis IV diagnosis were not eligible to receive mental health coverage from insurance companies (APA, 2013). In fact, Probst (2014) provided evidence that APA was intentional in ensuring that Axis IV was not codable and optional for billing purposes in efforts to preserve a degree of client confidentiality. As such, the new nonaxial coding system might actually increase accessibility of services depending upon insurance companies’ individual responses (APA, 2013). Beginning with the DSM-5, clinicians are advised to make a separate notation regarding contextual information, rather than including it in axial notation. However, the APA (2013) did not provide guidance regarding how or where to do so.
Although there is no longer an Axis for contextual factors, it is imperative that counselors maintain a holistic focus that aligns with our unique identity (Hansen, 2009). Along with a humanistic, strength- and competency-based perspective, counselors are sensitive to contextual and cultural considerations. Context refers to the interrelated conditions in which clients’ experiences occur, or any factors that surround their experience and illuminate their situation. As previously discussed, many traditional understandings of mental disorders highlight a pathology- and deficit-based perspective. When considering clients’ situations from a contextual perspective, counselors are responsible for incorporating attention to culture, gender and various developmental factors. “Eliminating axis IV does not eliminate the need to consider context—unless it can be shown that genetic and neurochemical factors alone account for the emergence, variation, and trajectory of mental and emotional disorder” (Probst, 2014, p. 129). Thus, counselors are challenged to find new ways to communicate information previously provided in the multiaxial system.
A firm understanding of clients’ context may lead to a more compassionate and holistic conceptualization of symptoms that could be better explained by contextual factors or environmental stressors (Eriksen & Kress, 2005; Kress & Paylo, 2014). In addition, epidemiological research suggests that psychosocial and environmental problems have moderate predictive value for understanding prognosis of major depression, suicidality, anxiety disorders and substance use disorders (Gilman et al., 2013). Additionally, contextually sensitive counselors define some mental disorders as being a person’s functional attempts to adapt to or cope with a dysfunctional context (Ivey & Ivey, 1999). It is important that any diagnostic discussions integrate a focus on these contextual factors.
Culture is an exceptionally important contextual consideration; through culture, clients define, express and interpret their beliefs, values, customs and gender role expectations (Bhugra & Kalra, 2010). Multicultural considerations should enlighten counselors’ diagnostic decisions and ultimately the treatment process. Although it still has room for development, the DSM-5 (2013) includes systematic information regarding gender and culture for each diagnostic category. In some cases, this is limited to a simple accounting of the prevalence of disorders within certain groups; in other cases, APA provided information regarding the diverse presentation or understanding of disorders. Further, the American Counseling Association’s (ACA) Code of Ethics (2014) emphasizes that culture influences manifestation and understanding of problems; thus, counselors must consider culture throughout the counseling and treatment process.
Counselors can use formal or informal assessment to explore and understand clients’ context. The DSM-5 includes a Cultural Formulation Interview (CFI) that counselors can use to help them understand clients’ context and its impact on their experiences and symptoms. The CFI may help counselors obtain the most clinically useful information, develop a relational connection with clients and ultimately make accurate diagnoses. The CFI is included in Section III of the DSM-5 and is a semi-structured interview composed of 16 questions that address both individual experience and social context. The text is divided into two columns, with counselor-generated questions on the right and instructions for application on the left. Two versions of the interview are available, one for the individual and one for an informant (e.g., a caregiver or a parent). The interviews also are available online at the APA’s (2014) DSM-5 website. The CFI also includes 12 Supplementary Modules, which provide additional questions used to assess domains of the 16-item CFI (e.g., cultural identity) as well as questions that counselors can ask during the cultural assessment of particular groups (e.g., children and adolescents, older adults, immigrants and refugees, and caregivers).
Should counselors elect not to use this more formal interview format to assess culture, there are multiple additional formal and informal cultural assessments as well as assessment guidelines that they can apply. For example, Castillo (1997) provided the following guidelines for culturally sensitive diagnosis: (a) assess the client’s cultural identity; (b) identify sources of cultural information relevant to the client; (c) assess the cultural meaning of a client’s problem and symptoms; (d) consider the impacts and effects of family, work and community on the complaint, including stigma and discrimination that may be associated with mental illness in the client’s culture; (e) assess for counselor personal biases; and (f) plan treatment collaboratively. Castillo’s guidelines offer a comprehensive assessment that may inform diagnostic practices.
The ACA’s Code of Ethics (2014) also indicates that counselors should recognize social prejudices that lead to misdiagnosis and overpathologizing of certain populations. It is impossible to understand clients’ unique situations and how to best help them if cultural considerations are not addressed. An understanding of clients’ culture in relation to diagnosis includes understanding cultural explanations of their experiences, their help-seeking behavior, the cultural framework of clients’ identity, cultural meanings of healthy functioning and cultural aspects that relate to the counselor–client relationship (Eriksen & Kress, 2005).
Counselors can address, consider and convey contextual factors through use of V Codes and Z Codes, and by including attention to contextual factors within the treatment record and conceptualization process (Kress, Paylo, Adamson, & Baltrinic, in press). In the DSM-5, the APA greatly expanded the list of codes to provide a means for documenting “other conditions and problems that may be a focus of clinical attention or that may otherwise affect the diagnosis, course, prognosis, or treatment of a patient’s mental disorder” (2013, p. 715). These are included alongside mental disorders and medical conditions on the nonaxial diagnosis discussed previously. Examples of V/Z Codes in the DSM-5 include the following: difficulties rooted in interpersonal issues (e.g., parent–child, sibling, partner distress), issues with abuse and neglect (e.g., partner abuse, child abuse, maltreatment), education or occupational difficulties, problems with housing and finances, difficulties within their social environment (e.g., phase of life, acculturation, target of discrimination), legal issues and other personal circumstances (e.g., obesity, nonadherence to treatment, borderline intellectual functioning). For example, a client who presents with major depressive disorder and reports a recent marital separation that has resulted in homelessness might receive a diagnosis of: 296.22 (F32.1) major depressive disorder, single episode, moderate; V61.03 (Z63.5) disruption of family by separation; and V60.0 (Z59.0) homelessness.
The move toward eliminating the multiaxial system emphasizes the idea that mental disorders do not occur apart from physical considerations and contextual struggles. In some ways, this change is consistent with a professional counseling philosophy. However, because there is no longer an infrastructure to cue consideration of contextual concerns, counselors must be ever more vigilant in identifying systematic ways to assess this information and integrate it into treatment plans in meaningful ways. How counselors convey this information may vary across providers and contribute to some confusion in communicating this information. Thus, the elimination of this axis may provide more flexibility at the expense of clear communication.
Functioning and Disability (Axis V)
Initially developed as the Health-Sickness Rating Scale, the GAF was introduced as Axis V of the DSM-III and DSM-IV (Aas, 2011). The scale called for clinicians to “consider psychological, social, and occupational functioning on a hypothetical continuum of mental health–illness. Do not include impairment in functioning due to physical (or environmental) limitations” (APA, 2000, p. 34). Over time, this single number scale came to be used to assist in payers’ determinations of medical necessity for treatment and in determining eligibility for disability compensation (Kress & Paylo, 2014). The APA discontinued use of the GAF in the DSM-5, and now suggests that clinicians use the World Health Organization Disability Assessment Schedule (WHODAS 2.0) as a measure of disability.
The GAF scale was removed from the DSM-5 because of perceived lack of reliability and poor clinical utility (APA, 2013). In a comprehensive review of literature regarding the GAF, Aas (2010, 2011) concluded insufficient reliability in clinical settings, lack of precision, inability to detect change and limited evidence of concurrent and predictive ability. One additional concern is the way in which the GAF combined attention to symptom severity and impairment. Hilsenroth et al. (2000) noted concern regarding overlap between previous Axis I and II diagnoses and GAF ratings, as evidenced by the APA’s continuing work to develop alternate measures of functioning such as the Global Assessment of Relational Functioning and the Social and Occupational Assessment Scale. Empirical evidence suggested that GAF scores relate to client and clinician perceptions of concerns (Bacon, Collins, & Plake, 2002; Hilsenroth et al., 2000) more so than with social adjustment or interpersonal problems (Hilsenroth et al., 2000). Others have expressed concern regarding the limits of use of the GAF with children (Schorre & Vandvik, 2004).
Ro and Clark (2009) argued that the construct of functioning is complex and multidimensional in a way that simple GAF ratings regarding symptom severity and impairment cannot capture. They stated that the World Health Organization’s (WHO) conceptualization of functioning as a component of health, and disability as impairment in functioning, was particularly helpful. Perhaps more importantly, Ro and Clark presented empirical evidence that functioning includes four key factors: well-being (including satisfaction, quality of life and personal growth), basic functioning in life demands, self-mastery, and interpersonal and social relationships. Certainly, this conceptualization fits well with an understanding of counseling as a profession dedicated to maximizing human development (Hansen, 2009).
Historically, payers approved the nature and extent of services based upon GAF scores, diagnosis, severity of symptoms, danger to self or others, and disability across life contexts. With the elimination of the multiaxial system, counselors will no longer note a GAF score, and will not have an assessment of functioning built into the documentation process. In the absence of GAF scores, the APA (2013) suggested that practitioners use alternative ways to note and quantify distress and disability in functioning. The APA also suggested that practitioners continue to assess for suicide and homicide risk and use available standardized assessments to assess for symptom severity and disability (APA, 2013).
The APA (2013) recommended the WHODAS 2.0 as a preferred measure for use in assessing clients’ functioning. The WHODAS 2.0 can be used with clients who have a mental or physical condition or disorder. The WHODAS 2.0 is a free assessment instrument that is provided in the DSM-5, included on the WHO’s website and available through the DSM-5 online assessment measures website (www.psychiatry.org/dsm5). A manual (Ustün, Kostanjsek, Chatteriji, & Rehm, 2010) also is available free of charge.
The WHODAS 2.0 is a 36-item measure that assesses disability in people 18 years and older. It assesses for disability across six different domains: self-care, getting around, understanding and communicating, getting along with people, life activities (e.g., work and/or school activities), and participation in one’s community/society. When completing the form, clients rate the six areas based on their functioning over the past 30 days. Respondents are asked to respond as follows: none (1 point), mild (2 points), moderate (3 points), severe (4 points), and extreme or cannot do (5 points). Scoring of the assessment measure involves either simple scoring (i.e., the scores are added up based on the items endorsed with a maximum possible score suggesting extreme disability as 180) or complex scoring (i.e., different items are weighted differently). The computer program that provides complex scoring can be found on the WHO’s website. The WHODAS 2.0 can be used to track changes in the client’s level of disability over time. It can be administered at specified intervals that are most relevant to the clients’ and counselors’ needs.
The WHODAS 2.0 has been decades in development, involving more than 65,000 participants in hundreds of studies conducted across 19 countries. Ustün et al. (2010) summarized psychometric evidence in support of the WHODAS as follows:
The WHODAS 2.0 was found to have high internal consistency (Cronbach’s alpha, α: 0.86), a stable factor structure; high test-retest reliability (intraclass correlation coefficient: 0.98); good concurrent validity in patient classification when compared with other recognized disability measurement instruments; conformity to Rasch scaling properties across populations, and good responsiveness (i.e., sensitivity to change). Effect sizes ranged from 0.44 to 1.38 for different health interventions targeting various health conditions. (p. 815)
The authors concluded that the instrument is robust and easy to use. Likewise, the assessment tool was tested in the DSM-5 field trials, and researchers suggested that it was sound and reliable in routine clinical evaluations (APA, 2013). Despite strong validity evidence, Kulnik and Nikoletou (2014) cautioned that the instrument seems to connect most cleanly to medical or physical elements of disability, sometimes at the expense of social aspects of disability. Similarly, the WHODAS 2.0 only assesses one of four areas of functioning identified by Ro and Clark (2009). Although counselors may find the WHODAS 2.0 helpful for understanding some elements of disability, they may do well to consider additional holistic and comprehensive opportunities to assess client functioning and strengths.
Discussion
Counselors should be aware that the act of rendering a DSM diagnosis is only one part of a comprehensive assessment. What one reports in terms of diagnosis is just a snapshot of the client. It does not capture the totality of one’s understanding regarding client strengths and limitations, nor does it indicate how counselors go about constructing that understanding. Any thorough assessment must take into account an understanding of all relevant factors. These include, but are not limited to, psychosocial factors such as psychological symptoms, family interactions, developmental factors, contextual factors, functional abilities and longitudinal-historical information.
Given elimination of the multiaxial system, we advise counselors to be especially alert to listing V or Z Codes as part of the diagnosis in order to maintain consideration for client context in addition to biology and symptomology. As with prior editions of the DSM, counselors can still use V or Z Codes as sole diagnoses or to augment other diagnoses. Counselors also should document contextual information in their records so that this information can be conveyed to others as appropriate and used to support clients’ treatment.
There are a number of models that can be used to guide counselors’ diagnostic, case conceptualization and treatment practices. One such model is the I CAN START model (Kress & Paylo, 2014), which follows:
- I (Individual) represents the individual counselor and his or her unique experiences, competencies, limitations and other personal factors;
- C (Context) relates to an understanding of the client’s unique context (e.g., culture, gender, sexual orientation, developmental level, religion/spirituality);
- A (Assessment and Diagnosis) represents the assessment of the client and his or her symptoms and the accompanying DSM-5 diagnosis;
- N (Necessary level of care) refers to the client’s required level of care (e.g., residential treatment, hospitalization, outpatient treatment, individual counseling, family therapy);
- S (Strengths) signifies the client’s strengths, resources, and capacities, which can be used in treatment to help him or her overcome his or her problems and thrive;
- T (Treatment) represents the utilization of an evidence-based treatment in addressing the presenting disorders or problems;
- A (Aims and objectives of treatment) denotes the development of clearly defined problems, with measurable goals and clear behavioral counseling objectives;
- R (Research-based interventions) refers to the use of counseling techniques that are based on research; and
- T (Therapeutic support services) involves the use of support services that may complement counseling interventions and treatments (e.g., case management, medication management, nutrition counseling, a physical exercise program, parent training, yoga, meditation).
The loss of the multiaxial system in the DSM-5 provides both opportunities and challenges to counselors. The exact outcome of how the new process will be implemented is not yet known, and only time will show the extent of its impact. With the loss of the multiaxial system, some of the structure associated with its use is also lost. Moving forward, counselors should continue to develop methods for assessing and documenting aspects of the multiaxial system that have been eliminated. With this change comes an opportunity to reaffirm holistic and integrated views of clients and to provide leadership for other mental health professions and professionals regarding how to incorporate this perspective into diagnostic practices.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) continues its 60-year legacy as a standard reference for clinical practice in the mental health field. Six mental health disorders are reviewed with a focus on changes between the DSM-IV-TR and the DSM-5 that represent the new landscape for each of these disorders, respectively. Following the summary of changes, a clinical scenario is presented so that counselors can capture the vision of using the DSM-5 in their counseling practice. Clinical formulation (sample diagnosis) using the DSM-5 is also presented for each disorder classification.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) continues its 60-year legacy as a standard reference for clinical practice in the mental health field. This practical, functional and flexible guide is intended for use by trained counselors in a wide diversity of contexts and facilitates a common language to communicate the necessary characteristics of mental disorders present in their clients (APA, 2013). As counselors use the DSM-5, they will notice an expanded discussion of developmental and life span considerations, cultural issues, gender differences, integration of scientific findings from the latest research in genetics and neuroimaging, and enhanced use of course, descriptive and severity specifiers for diagnostic precision (APA, 2013). They will also notice a dimensional approach to diagnosis, consolidation and restructuring of most mental disorders; a new definition of a mental disorder; and emerging assessments and monitoring tools so as to promote enhanced clinical case formulation.
The intent of this article is to assist all counseling specialists by presenting six clinical scenarios from the author’s counseling practice. The article begins by summarizing the clinical utility of the DSM-5 and provides recommendations for counselors on how to sequence their study of the new manual. Discussed next are use of the new emerging assessment measures, autism spectrum disorder, schizophrenia spectrum and other psychotic disorders, sleep-wake disorders, neurocognitive disorders, and comorbid conditions such as excoriation (skin-picking) disorder and post-traumatic stress disorder—with a focus on prominent changes between the DSM-IV-TR and the DSM-5. Clinical formulation and its associated rationale using the DSM-5 are presented for each disorder classification.
Counselors are encouraged to read the full manual and to especially read the Preface; Section I (i.e., Introduction, Use of the Manual, and Cautionary Statement for Forensic Use of DSM-5); Section III: Emerging Measures and Models (i.e., Assessment Measures); and Appendix (i.e., Highlights of Changes From DSM-IV to DSM-5) before they attempt applied clinical use of the manual. To appreciate the rationale for the DSM-5 changes, counselors are encouraged to read the DSM-IV-TR discussion on limitations to the categorical approach (APA, 2000, pp. xxxi–xxxii) and on the nonaxial format (p. 37). This sequencing of study will help counselors use the manual as intended and avoid diagnostic errors, as well as maintain cultural sensitivity and avoid historical and social prejudices in the diagnosis of pathology (ACA, 2014).
Cross-Cutting Symptom Measures and Disorder-Specific Severity Measures
Clinicians are to administer emerging assessment measures at the initial interview and to monitor treatment progress, thus serving to promote the use of initial symptomatic status and reported outcome information (APA, 2013). The DSM-5 cross-cutting symptom measures support comprehensive assessment by drawing attention to clinical symptoms that manifest across diagnoses. Cross-cutting symptom measures have two levels. Level 1 measures offer a brief screening of 13 domains for adults (i.e., depression, anger, mania, anxiety, somatic symptoms, suicidal ideation, psychosis, sleep problems, memory, repetitive thoughts and behaviors, dissociation, personality functioning, and substance use) and 12 domains for children and adolescents (i.e., depression, anger, irritability, mania, anxiety, somatic symptoms, inattention, suicidal ideation/attempt, psychosis, sleep disturbance, repetitive thoughts and behaviors, and substance use). Level 2 measures provide a more in-depth assessment of elevated Level 1 domains to facilitate differential diagnosis and determine severity of symptom manifestation. The DSM-5 disorder-specific severity measures correspond closely to the criteria that constitute the disorder definition and are intended to illuminate additional areas of inquiry that may guide treatment and prognosis (APA, 2013; Jones, 2012). Counselors can access these no-cost assessment measures at http://psychiatry.org/practice/dsm/dsm5/online-assessment-measures. The DSM-5 provides counselors with further information on the background and reasoning for use of these emerging measures in clinical practice (see pp. 733–748).
Autism Spectrum Disorder
The New Landscape
From as early as 1993, authors and researchers have referred to the various pervasive developmental disorders as autism spectrum disorder (Rutter & Schopler, 1992; Shuster, 2012; Tanguay, Robertson, & Derrick, 1998). They have also called for use of a dimensional rather than a categorical classification as used in DSM-IV and DSM-IV-TR (Kamp-Becker et al., 2010). Unlike the dichotomous approach of the DSM-IV-TR categorical model, the dimensional approach uses three or more rating scales to measure severity, intensity, frequency, duration or other characteristics of given diagnoses (Jones, 2012). Consensus in the research community for a spectrum classification is clearly demonstrated in that 95% of publications in the past 5 years have used the term “autism spectrum disorder.” Hence, the DSM-5 uses the term spectrum and further informs counselors that “autism spectrum disorder encompasses disorders previously referred to as early infantile autism, childhood autism, Kanner’s autism, high-functioning autism, atypical autism, pervasive developmental disorder not otherwise specified, childhood disintegrative disorder, and Asperger’s disorder” (APA, 2013, p. 53). Consolidating use of these dichotomous autism-based titles into a spectrum designation helps to avoid diagnostic confusion and to minimize fragmented treatment planning.
Based on factor structure models, the DSM-5 presents a major reconceptualization and reorganization of the DSM-IV-TR autistic disorder symptomatology (Guthrie, Swineford, Wetherby, & Lord, 2013). This new spectrum, or dimensional classification, helps counselors to properly assess deficits in social-emotional reciprocity (i.e., the inability to engage with others and share thoughts and feelings); nonverbal communicative behaviors used for social interaction (i.e., absent, reduced or atypical use of eye contact [relative to cultural norms], gestures, facial expressions, body orientation or speech intonation); ability to develop, maintain and understand relationships (i.e., absent, reduced or atypical social interest, manifested by rejection of others, passivity or inappropriate approaches that seem aggressive or disruptive); and marked presentations of restricted, repetitive patterns of behavior, interests or activities. This reconceptualization of autism in the DSM-5 provides counselors with a denser diagnostic cluster to reduce excessive application of the DSM-IV-TR pervasive developmental disorder not otherwise specified classification that resulted in overdiagnosis and concerning prevalence rates (Maenner et al., 2014).
The DSM-5 further recognizes autism due to Rett syndrome, Fragile X syndrome, Down syndrome, epilepsy, valproate, fetal alcohol syndrome or very low birth weight through use of the specifier associated with a known medical or genetic condition or environmental factor. Counselors also may use the specifiers with or without accompanying intellectual impairment and with or without accompanying language impairment. Examples of descriptive specifier usage include with accompanying language impairment—no intelligible speech or with accompanying language impairment—phrase speech. If catatonia is present, counselors record that separately as catatonia associated with autism spectrum disorder. Severity, or intensity of symptoms, for autism spectrum disorder are now communicated on three levels: Level 1 mild requiring support, level 2 moderate requiring substantial support, and level 3 severe requiring very substantial support (APA, 2013).
The level of interference in functioning and support required is communicated by using the DSM-5 Clinician-Rated Severity of Autism Spectrum and Social Communication Disorders scale (APA, 2013, p. 52). Examples of mild rating in the social communication psychopathological domain may include the following: without supports in place, deficits in social communication cause noticeable impairments; has difficulty initiating social interactions and demonstrates clear examples of atypical or unsuccessful responses to social overtures of others; and may appear to have decreased interest in social interactions. Examples of mild rating in the restricted interests and repetitive behaviors psychopathological domain may include rituals and repetitive behaviors (RRBs) that cause significant interference with functioning in one or more contexts, or resists attempts by others to interrupt RRBs or to be redirected from fixated interest (APA, 2013).
Examples of moderate rating in the social communication psychopathological domain may include marked deficits in verbal and nonverbal social communication skills, social impairments apparent even with supports in place, limited initiation of social interactions, and reduced or abnormal response to social overtures from others. Examples of moderate rating in the restricted interests and repetitive behaviors psychopathological domain may include RRBs and/or preoccupations and/or fixated interests that appear frequently enough to be obvious to the casual observer and inhibit functioning in a variety of contexts. Frustration or distress is apparent when RRBs are interrupted; it is difficult to redirect attention from fixated interest (APA, 2013).
Examples of severe rating in the social communication psychopathological domain may include severe deficits in verbal and nonverbal social communication skills that cause significant impairments in functioning, very limited initiation of social interactions, and minimal response to social advances from others. Examples of severe rating in the restricted interests and repetitive behaviors psychopathological domain may include preoccupations, fixed rituals and/or repetitive behaviors that significantly interfere with functioning in all domains; distinct distress when rituals or routines are interrupted; difficulty redirecting from fixated interest or returns to it quickly. Counselors are advised to review Table 2 Severity Levels for Autism Spectrum Disorder displayed in the DSM-5 (APA, 2013, p. 52).
Clinical Scenario
Walter, a 22-year-old male, was referred to counseling by the State Office of Rehabilitation for career and vocational assistance, with a special focus on his mental health needs and confirming the presence of his previous diagnosis of Asperger’s disorder given in 2004. Counselors working with adults presenting with autism spectrum symptoms will appreciate the DSM-5’s new adult textual narrative. Some of these additions help to understand adults like Walter, who:
- Must show persistent symptoms from early childhood across multiple contexts.
- Display difficulties processing and responding to complex social cues;
- Suffer from anxiety because of purposefully calculating what is socially intuitive for other adults;
- Express difficulty in coordinating nonverbal communication with speech;
- Struggle to comprehend what behavior is considered appropriate in one situation but not another; and
- Learn to suppress repetitive behavior in public.
Following assessment procedures outlined in the DSM-5 to use “standardized behavioral diagnostic instruments with good psychometric properties, including caregiver interview, questionnaires and clinician observation measures” (APA, 2013, p. 55) and by Jones (2010), clinical assessment of Walter included the following:
- Biopsychosocial clinical interview of Walter with his mother as an additional informant
- Level 1 Cross-Cutting Symptom Measure (see APA, 2013, pp. 733–744 or www.psychiatry.org/dsm5)
- The Clinician-Rated Severity of Autism Spectrum and Social Communication Disorders (see APA, 2013, p. 52 or www.psychiatry.org/dsm5)
- Historical evaluations (prior psychological testing results)
- Collateral reports from the referring vocational rehabilitation counselor
- Simon Baron-Cohen’s Autism Spectrum Quotient (Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001; Ketelaars et al., 2008)
Adhering to DSM-5 dimensional rather than DSM-IV-TR multiaxial classification (Jones 2012), Walter was diagnosed using this format:
299.00 Autism spectrum disorder; requiring substantial support for social communication and social interaction (level 2 moderate); requiring support for restricted repetitive behaviors, interests and activities (level 1 mild); without accompanying intellectual impairment; without accompanying language impairment; without catatonia.
Notice the diagnostic precision offered by the DSM-5 in comparison with Walter’s non-descriptive diagnosis using the DSM-IV-TR formulation: Asperger’s Disorder (APA, 2000). In contrast, the severity ratings for autism spectrum disorder are listed independently for social communication and restricted repetitive behaviors, rather than providing a global rating for both psychopathological domains (per the DSM-5 they are listed from most severe to least severe). For Walter, his moderate severity rating of requiring substantial support for social communication means: “Marked deficits in verbal and nonverbal social communication skills; social impairments apparent even with supports in place; limited initiation of social interactions; and reduced or abnormal responses to social overtures from others” (APA, 2013, p. 52). His mild severity rating of requiring support for restricted repetitive behaviors (RRBs) means: “Inflexibility of behavior causes significant interference with functioning in one or more contexts. Difficulty switching between activities. Problems of organization and planning hamper independence” (APA, 2013, p. 52). The diagnostic formulation offered to counselors in the DSM-5 provides a richer contextual description of the client to support more personalized treatment planning. This attention to dimensional ratings and individualized treatment strategies is also captured in the newly conceptualized schizophrenia spectrum disorders.
Schizophrenia Spectrum and Other Psychotic Disorders
The New Landscape
Counseling clients presenting with psychotic and schizophrenia spectrum disorders is challenging and diagnostically complex. To assist with these difficulties, the DSM-5 presents a new conceptualization to facilitate clinical utility and to streamline diagnostic formulations (Bruijnzeel & Tandon, 2011). Similar to autism, schizophrenia has been referenced as a spectrum disorder since 1995 (Kendler, Neale, & Walsh, 1995) and the DSM-5 marks the official recognition of this spectrum conceptualization by embedding the word in the diagnostic title. Essential to competent practice in this area is reading the section on key features that define the psychotic disorders on pages 87–88 of the DSM-5 (APA, 2013; e.g., delusions, hallucinations, disorganized thinking, grossly disorganized or abnormal motor behavior, and negative symptoms). Further critical reading is the new Clinician-Rated Assessment of Symptoms and Related Clinical Phenomena in Psychosis on the DSM-5 pages 89–90 (APA, 2013). These pages describe the heterogeneity of psychotic disorders and the dimensional framework for the assessment of primary symptom severity within the psychotic disorders. This spectrum conceptualization differs from the DSM-IV-TR categorical and mutually exclusive diagnostic system that assumed “mental disorders are discrete entities, with relatively homogeneous populations that display similar symptoms and attributes of a disorder” (Jones, 2012, p. 481).
The new Clinician-Rated Dimensions of Psychosis Symptom Severity (CRDPSS) is used to understand the personal experience of the client, to promote individualized treatment planning, and to facilitate prognostic decision making (Flanagan et al., 2012; Heckers et al. 2013). Counselors can obtain the CRDPSS in the DSM-5 pages 742–744 (APA, 2013) or www.psychiatry.org/dsm5. The CRDPSS is an eight-item measure used to assess the severity of mental health symptoms that are important across psychotic disorders. These symptoms include delusions, hallucinations, disorganized speech, abnormal psychomotor behavior, negative symptoms (i.e., restricted emotional expression or avolition), impaired cognition, depression and mania. Psychosis symptoms are rated on a five-point scale: not present, equivocal (severity or duration not sufficient to be considered psychosis), mild (little pressure to act, not very bothered by symptoms), moderate (some pressure to respond or somewhat bothered by symptoms) and severe (severe pressure to respond to voices or very bothered by voices).
According to the DSM-5, proper use of the CRDPSS may include clinical neuropsychological assessment (especially of client cognitive functioning) to help guide diagnosis and treatment. Counselor “assessment of [client] cognition, depression, and mania symptom domains is vital for making critically important distinctions between the various schizophrenia spectrum and other psychotic disorders” (APA, 2013, p. 98). Depending on the stability of client symptoms and treatment status, the CRDPSS may be completed at regular intervals as clinically indicated to track changes in client symptom severity over time. Consistently high scores on a specific domain may indicate significant and problematic areas for the client that may warrant further assessment (mental status examination), treatment (counseling and pharmacological), and follow-up (case management).
In the DSM-5, delusional disorder is retained as listed in DSM-IV-TR, including its classic subtypes of erotomanic, grandiose, jealous, persecutory and somatic. Some textual updates occur in the DSM-5 for brief psychotic disorder that place emphasis on disorganized or catatonic behavior. Schizophreniform disorder in the DSM-5 parallels the description in the DSM-IV-TR. Diagnostic precision for schizophrenia in the DSM-5 is communicated with new course specifiers that can “be used after a 1-year duration of the disorder and if they are not in contradiction to the diagnostic course criteria” (APA, 2013, p. 99). These new course specifiers communicate a time period in which the symptom criteria are fulfilled (acute), a period of time during which improvement after a previous episode is maintained and in which the defining criteria of the disorder are only somewhat fulfilled (partial remission), or a period of time after a prior episode during which no disorder-specific symptoms are present (full remission). Counselors also can communicate these specifiers based on first episode, multiple episodes, continuous episodes or unspecified. Use of these specifiers assists counselors in determining the intensity, frequency and duration of clinical intervention services that are more person-centered.
To align with a dimensional, or spectrum paradigm, the categorical DSM-IV-TR schizophrenia subtypes (i.e., paranoid type, disorganized type, catatonic type, undifferentiated type and residual type) are not used in the DSM-5 because they are included in the previously described CRDPSS. Research also does not support the use of the subtypes and does not indicate any qualitative differences between the subtypes that impact treatment planning or symptom presentation (Tandon et. al., 2013). Catatonia, a syndrome of disturbed motor, mood and systemic signs, becomes a specifier in the DSM-5, applicable for neurodevelopmental, depressive, bipolar and all psychotic disorders (APA, 2013). Unlike the DSM-IV-TR, the DSM-5 does not contain the following exception clause to diagnose schizophrenia: “Only one Criterion A symptom is required if delusions are bizarre or hallucinations consist of a voice keeping up a running commentary on the persons’ behavior or thoughts, or two or more voices conversing with each other” (APA, 2000, p. 312). Removal of this language restricts classification to avoid excessive classification in nonclinical profiles, thus promoting ethical practice (ACA, 2014).
Although the DSM-5 acknowledges that “there is growing evidence that schizoaffective disorder is not a distinct nosological category” (APA, 2013, pp. 89–90; see also Malaspina et al., 2013), this disorder is retained, with some textual refinements to more stringently define the clinical syndrome. These changes include the following: criterion B: “lifetime duration of the illness” (APA, 2013, p. 105); and criterion C: major mood episode must be “present for the majority of the total duration for the active and residual portion of the illness” (APA, 2013, p. 105) instead of the DSM-IV-TR’s focus on substantial portion for the active and residual portion of the illness.
Clinical Scenario
Ryan, a 22-year-old Caucasian male, presented with an extensive history of auditory hallucinations and erotomanic and paranoid delusions. In the spirit of the DSM-5, he was administered the CRDPSS six times, beginning with the onset of counseling and then at various counseling sessions during his treatment. Use of the CRDPSS promotes clinical utility. For example, Ryan is able to identity trends and patterns related to life stressors and symptom elevations and reductions. This level of clinical assessment provides a framework for targeted treatment planning and clinical intervention. Ryan also feels empowered over his mental illness and obtains a more positive perspective regarding his self-efficacy with coping skills to manage his psychotic symptoms. Most importantly, the CRDPSS encourages measurement-based care in the burgeoning era of practice-based evidence requirements (Tandon et al., 2013). Adhering to the DSM-5 dimensional classification, I diagnosed Ryan using this format:
295.70 Schizoaffective disorder, bipolar type, severe hallucinations, moderate delusions (erotomanic and persecutory), moderate abnormal psychomotor behavior, moderate negative symptoms, equivocal disorganized speech, continuous episode, currently in partial remission, without catatonia.
Compare the DSM-5 clinical formulation to the DSM-IV-TR diagnostic formulation:
295.70 Schizoaffective disorder, bipolar type.
The DSM-5 diagnostic conceptualization offers a contextualized framework in “developing a comprehensive treatment plan that is informed by the individual’s cultural and social context” (APA, 2013, p. 19) by rating primary symptoms of psychosis in order of severity so as to promote prognostic decision-making. This level of diagnostic specificity also is found in the DSM-5 sleep-wake disorders.
Sleep-Wake Disorders
The New Landscape
Sleep-wake disorders in the DSM-5 represent a radical revamping of diagnostic syndromes, clinical conceptualization and specifier annotations. This is because the “DSM-IV was prepared for use by mental health and general medical clinicians who are not experts in sleep medicine” (APA, 2013, p. 362). Grounded in the current International Classification of Sleep Disorders, 2nd edition (ICSD-2), the DSM-5 sleep-wake disorders work group used this classification system as a benchmark for diagnostic revision. When counselors read each sleep-wake disorder in the DSM-5, they will discover that a note about relationship to the ICSD is presented. Because of the new sleep-wake disorder conceptualization and the dimensional (instead of categorical) formulation of mental disorders in the DSM-5, counselors are to use the emerging measures for sleep-wake disorders for children and adults located at www.psychiatry.org/dsm5.
As counselors read the sleep-wake disorders chapter in the DSM-5, they will notice an increased emphasis on a multidimensional approach to assessment that includes medical examination, such as the use of polysomnography, quantitative electroencephalographic analysis and testing for hypocretin (orexin) deficiency (APA, 2013). They will also notice a greater emphasis on the dynamic relationship between sleep-wake disorders and certain mental or medical conditions, and that pediatric and developmental criteria and the general text are integrated based on existing neurobiological and genetic evidence and biological validators (Kaplan, 2013). The DSM-5 sleep-wake disorders textual descriptors use the terminology “coexisting with” or “comorbidity” instead of the DSM-IV-TR “related to” or “due to.” Sleep-wake disorders in the DSM-5 further provide diagnostic precision by offering use of course specifiers (i.e., episodic, persistent, recurrent, acute, subacute), descriptive specifiers (i.e., with mental disorder, with medical condition, with another sleep disorder), and severity specifiers (i.e., mild, moderate, severe).
The insomnia-based sleep-wake disorders focus on problems with initiating or maintaining quality sleep. Some of these disorders preclude assessment by a counselor, as they require examination by a sleep medicine expert. The DSM-IV-TR primary insomnia and insomnia related to another mental disorder are merged in the DSM-5 to become insomnia disorder. The DSM-IV-TR primary hypersomnia and hypersomnia related to another mental disorder are merged to become the DSM-5 hypersomnolence disorder. Narcolepsy is retained in the DSM-5 with substantial symptom description changes, five new specifiers and requirements for sleep medicine examination to confirm a diagnosis. Narcolepsy now requires either the presence of cataplexy (sudden loss of muscle tone), hypocretin deficiency as measured using cerebrospinal fluid, or REM sleep latency deficiency as measured using polysomnography (APA, 2013). Breathing-related sleep disorders in the DSM-5 include obstructive sleep apnea hypopnea, central sleep apnea (new for the manual) and sleep-related hypoventilation (new for the manual). Circadian rhythm sleep-wake disorders in the DSM-5 no longer recognize jet lag, resulting in five types (i.e., delayed sleep phase, advanced sleep phase, irregular sleep-wake, non-24-hour sleep-wake and shift work) for counselors to select when diagnosing this syndrome. Parasomnias, defined as abnormal behavior or physiological events during sleep, also are reconceptualized in the DSM-5. The DSM-IV-TR sleepwalking disorder and sleep terror disorder are merged to become the DSM-5 non–rapid eye movement sleep arousal disorder, with sleepwalking type, sleep-related eating, sleep-related sexual behavior, and sleep terror type specifiers (APA, 2013). Nightmare disorder is retained with no substantial changes from the DSM-IV-TR. The DSM-IV-TR parasomnia not otherwise specified is renamed in the DSM-5 to rapid eye movement sleep behavior disorder for disruptive dream enacting behaviors, and DSM-IV-TR dyssomnia not otherwise specified is renamed in the DSM-5 to restless legs syndrome.
Clinical Scenario
Jasmine, a 36-year-old Caucasian female, is married and has four children. She reported a history of major depression (with two to three episodes of intense suicidal ideation) and generalized anxiety disorder. Results from the World Health Organization’s Adult ADHD Self-Report Scales (Kessler et al., 2004) indicated possible attention-deficit/hyperactivity disorder combined presentation. Results from the psychometric Conners’ Continuous Performance Test II confirmed the presence of a mild to moderate ADHD combined presentation profile. Despite pharmacological (both prescription and over the counter) and psychological (sleep hygiene and behavioral-focused) interventions, Jasmine continued to report daytime sleepiness, fatigue and unrefreshing sleep throughout the week, lasting for many months. This produced functional impairment with employment obligations and interpersonal relationships.
In the spirit of the DSM-5 and in collaboration with her general practitioner, Jasmine was referred to a local sleep medicine clinic to receive formal sleep-wake disorder testing (polysomnography). This was done to confirm the presence of an independent sleep-wake disorder not better accounted for by her depression and anxiety disorders. The resulting sleep-wake study report included the following excerpts:
This is 36-year-old female patient with a past medical history that is remarkable for gastric reflux, allergies and asthma. Patient is overweight with a BMI (body mass index) of 26.31. There is a longstanding history of: frequent awakenings, use of sleeping pills, frequent difficulty waking up, nonrestorative sleep, excessive daytime sleepiness, nasal congestion, frequent loud snoring, palpitations, night sweats and waking up with muscle paralysis. Patient complains of excessive daytime sleepiness with an Epworth Sleepiness score that is abnormal at 14 out of 24. Total sleep time is adequate at 8 hours per night. Patient denies smoking and drinking alcohol. Current medications include: Pantoprazole, Simvastatin, Amitriptyline, Loratadine and Fluticasone. As such, an overnight sleep study was ordered for evaluation of an underlying sleep-related breathing disorder.
Interpretation:
- Obstructive apneas (suspension of external breathing) of 17.1/hour associated with oxygen desaturation to as low as 72%. This is consistent with the diagnosis of moderate Obstructive Sleep Apnea.
- Sleep-related hypoventilation/hypoxemia due to sleep apnea is present.
- Severe initial insomnia.
Recommendations:
- Continuous positive airway pressure (CPAP) therapy should be offered to this patient given the risk of stroke and the significant daytime sleepiness. As such, a second overnight sleep study for CPAP titration is strongly recommended. If daytime sleepiness persists despite adequate CPAP therapy, then further evaluation for hypersomnolence should be considered.
Recall that hypersomnolence, excessive sleepiness, is a new disorder for the DSM-5. Addition of this diagnosis conforms to the sleep medicine expert’s recommendation for potential comorbid existence.
Adhering to the DSM-5 dimensional rather than the DSM-IV-TR multiaxial classification (Jones, 2012), Jasmine received the following diagnostic formulation:
- 327.23 Moderate obstructive sleep apnea hypopnea (see APA, 2013, pp. 378–383);
- V61.10 Relationship distress with spouse (see APA, 2013, p. 716);
- 296.32 Moderate major depressive disorder, recurrent (the Level 2 — Depression—Adult [PROMIS Emotional Distress—Depression—Short Form] and the Severity Measure for Depression—Adult [Patient Health Questionnaire–9] were administered to determine severity rating (see also Jones, 2012; APA, 2014);
- 327.24 Mild idiopathic sleep-related hypoventilation (see APA, 2013, pp. 387–390);
- 314.01 Mild attention-deficit/hyperactivity disorder, combined presentation, in partial remission (see APA, 2013, pp. 60–61 for discussion on new severity and remission specifier options); and
- 300.02 Mild generalized anxiety disorder (the Severity Measure for Generalized Anxiety Disorder—Adult [APA, 2014] was administered to determine severity rating).
Counselors are reminded that depression, anxiety and cognitive changes often accompany sleep-wake disorders and must be addressed in treatment planning and management (APA, 2013). To assist with targeted treatment interventions for sleep-wake disorders, counselors are encouraged to use Milner and Belicki’s (2010) sleep hygiene recommendations.
Neurocognitive Disorders
The DSM-IV-TR chapter “Dementia, Delirium, Amnestic, and Other Cognitive Disorders” is renamed to “Neurocognitive Disorders” (NCDs) in the DSM-5. Cognitive impairments occur in most mental disorders, including schizophrenia, bipolar disorder, depression, attention-deficit/hyperactivity disorder and autism (APA, 2013). However, the DSM-5 NCDs work group focused on those disorders for which the cognitive deficit is the primary one and is attributable to known physical or metabolic brain disease—hence the designation neurocognitive (Campbell, 2013).
To delineate between normative aging declines and lifelong patterns, the DSM-5 requires neuropsychological testing as part of the clinical evaluation process (except for delirium). Compared to the DSM-IV-TR, the NCDs in the DSM-5 represent a significant reorganization and reconceptualization (Ganguli, 2011) reflected in two new diagnostic categories: major and mild NCDs (Geda & Nedelska, 2012). Major NCD is characterized by significant cognitive decline, interference with activities of daily living, and symptom manifestation two or more standard deviations from the mean on neurocognitive domains (see Table 1, APA, 2013, pp. 593–595). Specifiers for the major NCD designation include mild (difficulties with instrumental activities of daily living, such as housework or managing money), moderate (difficulties with basic activities of daily living, such as feeding and dressing), and severe (fully dependent).
In contrast to major NCD, mild NCD is characterized in the DSM-5 as modest cognitive decline, intact activities of daily living, and symptom manifestation one standard deviation from the mean on neurocognitive domains. Mild NCD is a former diagnostic consideration from the DSM-IV-TR (2000) Appendix B: Criteria Sets and Axes Provided for Further Study (p. 764). Mild NCD is considered an up-streaming diagnostic conceptualization to assist with early diagnostic detection because the neuropathology underlying mild NCD emerges well before the onset of clinical symptoms (APA, 2013).
The DSM-5 offers two new NCD designations: probable and possible. Probable is added to the diagnostic title if there is evidence of a causative disease genetic mutation from either genetic testing, evidence of family history, evidence from laboratory blood testing, or evidence from neuroimaging. Possible is used if there is no evidence resulting from the previously mentioned probable objective factors (APA, 2013). Counselors also may use the retained DSM-IV-TR descriptive specifier, without or with behavioral disturbance to indicate the presence of psychotic symptoms, mood disturbance, agitation, apathy or other behavioral symptoms.
The DSM-5 contains 10 etiological specifiers (formally referred to as subtypes in the DSM-IV-TR). The DSM-5 changed the title of the DSM-IV-TR Pick’s disease to frontotemporal lobar degeneration and changed the DSM-IV-TR’s Creutzfeldt–Jakob disease to Prion disease so as to more objectively communicate the active pathophysiological mechanisms responsible for the neuronal degeneration and resulting cognitive disturbances (APA, 2013). The DSM-5 added Lewy body disease and multiple etiologies as etiological specifiers and merged the DSM-IV-TR dementia due to head trauma and postconcussional disorder (found in Appendix B: Criteria Sets and Axes Provided for Further Study) to become traumatic brain injury (TBI). Counselors will appreciate the table listed on page 626 (APA, 2013) that presents severity ratings for TBI, and will find that Jones, Young, and Leppma’s (2010) article complements the DSM-5 conceptualization of TBI and offers additional assessment and diagnostic assistance.
Clinical Scenario
Jaxson, a male client in his mid-40s who suffered three TBIs, each resulting from independent automobile accidents, presented for counseling. He presented with post-concussion syndromes reflected in physical symptoms (headaches, dizziness, fatigue, noise/light intolerance, insomnia, nausea, physical weakness), cognitive symptoms (memory complaints, poor concentration), and emotional symptoms (depression, anxiety, irritability, increased aggression, mood lability). Textual additions to the DSM-5 further explained the causal relationship between TBIs and major depressive episodes, facilitating a more accurate clinical formulation. The most salient DSM-5 (APA, 2013) diagnostic guidelines included the following:
- With moderate and severe TBI, in addition to persistence of neurocognitive deficits, there may be associated neurophysiological, emotional, and behavioral complications. These may include . . . depression, sleep disturbance, fatigue, apathy, inability to resume occupational and social functioning at pre-injury level, and deterioration in interpersonal relationships.
- Moderate and severe TBI have been associated with increased risk of depression. (p. 626)
- Individuals with TBI histories report more depressive symptoms, and these can amplify cognitive complaints and worsen functional outcome. (p. 627)
- There are clear associations, as well as some neuroanatomical correlates, of depression with . . . traumatic brain injury. (p. 181)
Using the DSM-5’s Severity Ratings for TBI, three previously administered clinical neuropsychological tests and the DSM-5’s Table 1 Neurocognitive Domains, Jaxson received the following dimensional diagnostic formulation per the DSM-5 (APA, 2013):
- 293.83 Moderate-severe depressive disorder due to TBI, with major depressive-like episode (p. 181; coding rules require that a mental disorder due to another medical condition be listed first; pp. 22–23);
- Moderate-mild disability (87 per self-administered World Health Organization Disability Assessment Schedule [WHODAS] 2.0; pp. 745–748);
- 331.83 Probable mild neurocognitive disorder (NCD) due to TBI (pp. 624–627);
- V62.29 Other problem related to employment (recent change of job, underemployment and psychosocial stressors related to work due to TBI; p. 723); and
- V61.29 Relationship distress with spouse (due to TBI; p. 716).
This approach to clinical case formulation also is demonstrated in the assessment and diagnosis of post-traumatic stress disorder and excoriation (skin-picking) disorder.
Comorbid Diagnostic Formulation
Comorbidity refers to the presence of multiple diagnoses or pathologies within the same individual (Jones, 2012). This final section presents a discussion on the DSM-5’s new obsessive-compulsive and related disorder, excoriation (skin-picking) disorder and the revised conceptualization of post-traumatic stress disorder.
Excoriation (Skin-Picking) Disorder
Excoriation, also referred to as dermatillomania (Grant et al., 2012), is characterized by the repetitive and compulsive picking of skin, leading to tissue damage, and is a new diagnosis to the DSM-5. This addition reflects the growing prevalence of this psychiatric condition (Grant et. al., 2012). Excoriation is characterized by compulsive picking, rubbing, squeezing, lancing or biting of the skin. Not included in this disorder are individual behaviors that involve nail biting, lip biting or cheek biting. If individuals manifest these conditions they are coded as other specified obsessive-compulsive related disorder (APA, 2013, p. 263). Cutting, or nonsuicidal self-injury, is not a codable mental disorder in the DSM-5 (see APA, 2013, pp. 803–806) and is not conceptualized in the symptomology of excoriation. Counselors are encouraged to consider cutting behavior in their clients as manifestations of symptoms related to depressive disorders, bipolar disorders, anxiety disorders, trauma disorders—and most particularly dissociative identity disorder and borderline personality disorder, in which self-injurious behavior is frequent. Individuals engaged in excoriation may target their face, arms, hand, skin irregularities, pimples, calluses or scabs. They may use objects such as tweezers, pins, scissors and fingernails and be triggered by anxiety, boredom, distress or tension (Grant et al., 2012). Some individuals with excoriation display rituals (e.g., biting off, chewing and swallowing skin), permanent skin damage, scarring, lesions, infection or disfigurement. Individuals with excoriation spend several hours per day for months and years picking at their skin, thinking about picking, and resisting urges to pick. Because the skin-picking is so frequent, pain is not routinely reported. Marked functional impairment from excoriation may include work interference, missed school, difficulty managing school tasks and studying, and avoidance of social or entertainment events. Excoriation cannot be due to physiological effects of a substance (e.g., methamphetamine or cocaine), to another medical condition (e.g., scabies), or better explained by symptoms of another disorder (APA, 2013).
Post-Traumatic Stress Disorder
Some important modifications to post-traumatic stress disorder occur in the DSM-5. First, the DSM-IV-TR language has shifted from “threat to the physical integrity of self or others” (APA, 2000, p. 467) to “sexual violence” (APA, 2013, p. 271). Second, the DSM-5 removed the DSM-IV-TR criterion A2 “subjective fear-based distress” because not all traumatized individuals experience fear, terror or horror when exposed to a trauma stressor. Some traumatized individuals may become anhedonic, dysphoric, aggressive or phobic; experience arousal and reactive-externalizing behaviors; or experience dissociation. Third, a new trauma exposure source is added to the traditional DSM-IV-TR trauma sources (i.e., directly experiencing, witnessing, and learning that a traumatic event occurred to a close family member or friend): “experiencing repeated or extreme exposure to aversive details of the traumatic event(s)” (APA, 2013, p. 271). An important note regarding this new exposure source in the DSM-5 indicates that “criterion A4 does not apply to exposure through electronic media, television, movies, or pictures, unless exposure is work related” (APA, 2013, p. 271). Examples of work-related electronic media exposure may include an individual who edits graphic news video or pictures, an individual who performs frequent digital-based forensic science investigations of graphic crime scenes, or an individual who views military-oriented electronic images displaying graphic human remains captured from unmanned aerial vehicles. Fourth, the DSM-5 requires that an individual manifest at least one symptom from each of the following pathological clusters:
- Intrusion symptoms;
- Persistent avoidance of stimuli;
- Negative alterations in cognitions and mood (new to the DSM-5); and
- Marked alterations in arousal and reactivity.
Fifth, the DSM-IV-TR specifier “delayed onset” is renamed to “delayed expression” in the DSM-5 so as to communicate whether the full diagnostic criteria are not met until at least 6 months after the trauma-causing event (APA, 2013, p. 272). Sixth, “with dissociative symptoms” (Dalenberg & Carlson, 2012) is a new descriptive specifier that can include either depersonalization (e.g., feeling as though one were in a dream; feeling a sense of unreality of self or body or of time moving slowly) or derealization (e.g., the world around the individual is experienced as unreal, dreamlike, distant or distorted; APA, 2013). Seventh, separate diagnostic criterion exist for children ages 6 years and younger. Counselors are encouraged to read van den Heuvel and Seedat (2013) for a detailed review of screening measures and diagnostic instruments for post-traumatic stress disorder in preschool populations.
Clinical Scenario
Mary, a female in her mid-50s, presented with an extensive history of sexual trauma resulting in post-traumatic stress disorder and excoriation. To verify the presence and severity of her trauma and excoriation, Mary was administered the DSM-5 Level 1 cross-cutting symptom measure. Elevated responses (i.e., feeling nervous, anxious, frightened, worried, or on edge and feeling driven to perform certain behaviors or mental acts over and over again) triggered administration of the DSM-5 Level 2 cross-cutting symptom measures (i.e., the Repetitive Thoughts and Behaviors Scale, the National Stressful Events Survey PTSD Short Scale, and the Modified Brief Dissociative Experiences Scale). Adhering to the DSM-5 dimensional classification, Mary’s diagnostic formulation was conceptualized in the following format:
- 309.81 Moderate post-traumatic stress disorder, with mild depersonalization
- 698.4 Excoriation (skin-picking) disorder.
This diagnostic formulation contains a layered intensity description as both the disorder and the descriptive specifier have a severity rating; hence promoting clinical utility by informing Mary’s treatment plan and assisting with prognostic and outcome factors (APA, 2013). For example, this level of diagnostic precision targeted Mary’s cognitive, affective and behavioral post-traumatic and depersonalization symptoms individually, rather than globally.
Conclusion
The DSM-5 represents 12 years of culminating work among hundreds of medical and mental health professionals. The manual was revised in a manner so as to stimulate new clinical perspectives, to promote a new generation of research into the biological markers of mental health disorders and to facilitate more reliable diagnoses of the disorders (APA, 2013). This article presented clinical scenarios from actual clients the author worked with in an outpatient counseling private practice. The intent is that counselors feel more comfortable and confident in their use of the DSM-5 to develop a counseling professional identity that stimulates client growth and development (Erikson & Kress, 2006; King, 2012).

The American Psychiatric Association introduced emerging measures to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) classification system. The authors present a primer on dimensional assessment and a review of the emerging measures endorsed by the American Psychiatric Association. The development of the emerging measures is discussed in light of the 1999 Standards for Educational and Psychological Testing and the DSM-5 criteria, showing that the measures lack conformity to various evidences of validity and lack alignment with the DSM-5 criteria. Hence, counselors should be cautious in the adoption of such measures because the measures may not augment comprehensively the categorical system of diagnosis currently endorsed by the American Psychiatric Association.
Keywords: diagnosis, dimensional assessment, DSM-5, measures, American Psychiatric Association
Historically, counselors relied on the categorical system of diagnosis employed by the American Psychiatric Association (APA) and included in the variations of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Jones (2012) highlighted the introduction of dimensional measures for diagnosis in the fifth edition of the DSM (DSM-5). Whereas a categorical approach to diagnosis classifies a diagnosis as either present or absent, a dimensional approach to diagnosis entails using measures to evaluate the extent to which symptoms exist (Jones, 2012). Hence, the dimensional approach provides a continuum to evaluate symptoms, whereas a categorical system does not. The APA (2013g) affirmed that the measures in the DSM-5 are to be used in conjunction with other diagnostic materials and that they are designed to provide a dimensional approach to diagnosis, as opposed to a categorical approach. The purpose of this article is to review the dimensional measures in conjunction with diagnostic criteria and standards for psychological measures.
The dimensional approach to diagnosis does have certain advantages, such as the ability to address comorbid symptoms and an increased utility in research (Bjelland et al., 2009; Jones, 2012; Kraemer, Noda, & O’Hara, 2004). However, categorical approaches to diagnosis are more easily operationalized (Bjelland et al., 2009) and dimensional diagnoses can be converted easily to cut-points to provide a categorical system (Kraemer et al., 2004). Clinical utility is a primary concern with implementing dimensional classifications for diagnoses (Livesley, 2007). With respect to the medical model, physicians diagnose and treat an illness; hence, an illness is present (and therefore treated) or is not present. Dimensional diagnoses present a different paradigm in which a disorder exists on a continuum. If a disorder is only somewhat present, the justification for treatment often becomes ambiguous, and consequently, the processes of charting the course of the diagnosis and conducting research become ambiguous as well. However, given the propensity of researchers to utilize instruments that measure constructs on a continuum, dimensional classifications may offer a method of demonstrating variability within a diagnosis (Helzer, van den Brink, & Guth, 2006). Dimensional classifications may be more helpful in measuring symptoms related to personality disorders (Livesley, 2007), anxiety and depression (Bjelland et al., 2009), and substance use (Helzer et al., 2006), due to the employment of different treatment modalities based on symptom severity. For example, medication management may not be considered with mild depression even though it may be effective; however, it may become a stronger consideration with moderate or severe depression (Stewart, Deliyannides, Hellerstein, McGrath, & Stewart, 2012).
Livesley (2007) advocated for integrating categorical and dimensional classifications for diagnoses. However, Helzer et al. (2006) indicated that a dimensional diagnosis must be associated with the operational definition of the said diagnosis, which implies that dimensional assessments must address the appropriate content to obtain a valid measure of the intended classification (i.e., diagnosis). What follows is an overview of evidences of validity for measures and an evaluation of dimensional measures advocated by the APA (2013g).
Cross-Cutting Symptom Measures
The APA (2013g) provided a section in the DSM-5 titled “Emerging Measures and Models” (p. 729) that contained “tools and techniques to enhance the clinical decision-making process, understand the cultural context of mental disorders, and recognize emerging diagnoses for further study” (p. 731). At the forefront of this section the APA introduced cross-cutting symptom measures (CCSMs), which are utilized for consideration across diagnostic symptoms. The DSM-5 only includes a few CCSMs, but the APA’s website (2014) offers access to a comprehensive list of CCSMs. CCSMs include two levels; Level 1 is concise, including 1–4 items on each domain, while Level 2 is more comprehensive, including a measure for each domain. The Level 1 CCSMs are more general measures that include symptoms across domains consistent with common diagnostic categories (e.g., depression, anxiety; APA, 2013g) and assess a wider scope of time (i.e., two weeks). The Level 1 CCSMs are designed for adults (23 items across 13 domains) or children (25 items across 12 domains). Adults and children/adolescents between the ages of 11 and 17 may complete self-report versions. A parent/guardian version is available for children between the ages of 6 and 17.
The Level 2 CCSMs are utilized after finding threshold scores from Level 1 measures. Level 2 measures contain more detailed symptom investigation that can help with diagnosis and treatment, including assessment of a shorter time period (i.e., 7 days). Level 2 measures include such symptoms as depression, anger, mania, anxiety, somatic symptoms, sleep disturbance, repetitive thoughts and behaviors, substance abuse, inattention, and irritability. Certain measures address how often the individual has been bothered by a symptom within a time period of 7 days, and others ask the individual to pick a statement in a cluster that best represents the way he or she has been feeling within the past 7 days. Similar to the Level 1 measures, adults and children/adolescents between the ages of 11 and 17 may complete a self-report version; a parent/guardian version is available for children between the ages of 6 and 17. These measures are to be used at the early stages of treatment and throughout the treatment process.
When comparing the Level 2 measures advocated by the APA (2013g) to the emotional and behavioral symptoms included in the DSM-5 diagnoses, many crucial criteria are absent, thereby inadequately addressing validity evidence based on test content. This dearth of missing criteria may indicate a lack of consistency between the measures and the DSM-5 diagnostic criteria. Furthermore, the Level 2 measures focus more on specific symptoms than on actual diagnoses. For example, the CCSMs include assessments of anger, which is a symptom of many disorders in the DSM-5, but not a disorder itself. In addition, common psychometric properties, such as the reporting of reliability estimates of the scores, are not readily apparent, if published at all. Therefore, standards related to the alignment of the instruments with DSM symptoms (i.e., evidence based on test content) are circumspect. As Helzer et al. (2006) reported, the dimensional approach to diagnosis must align with the definition of the diagnosis in the DSM-5.
Connecting Validity Standards to CCSMs
Pertinent to the utilization of the emerging measures for the purposes of diagnosis and clinical decision making is the extent to which the measures align with diagnostic criteria and are useful. The American Educational Research Association (AERA), the American Psychological Association, and the National Council on Measurement in Education (NCME) jointly publish the Standards for Educational and Psychological Testing. AERA et al. (1999) outlined issues related to instrument development, fairness and bias, and application of results to various settings (e.g., educational, vocational, psychological). With respect to evaluating research, issues of test construction, specifically evaluating validity and reliability, need to be addressed. According to AERA et al., “validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of test” (1999, p. 9). Validity, therefore, is not simply about the alignment of an instrument with theory and research, but also about how the scores are used. The most recent edition of the standards was published in 1999, which represented the fourth edition of the joint publication and the sixth publication by at least one of the representative bodies. As of August 2013, AERA et al. approved a revision to the 1999 Standards; however, a publication date is pending the development of a new agreement regarding how the revised Standards will be managed and published (AERA et al., 2009). Thus, the 1999 Standards represent the most current edition for measurement guidelines.
AERA et al. (1999) identified five evidences for evaluating the validity of a measure: (a) evidence based on test content, (b) evidence based on response processes, (c) evidence based on internal structure, (d) evidence based on relationships to other variables and (e) evidence based on consequences of testing. Evidence based on test content is specifically related to the extent to which the items are aligned with existing theory and the operational definition of the construct. Evidence of test content often is established through documentation of a review of extant literature and expert review. Evidence based on response processes includes an analysis of how respondents answer or perform on given items. In counseling research, some documentation about how respondents interpret the items may be noted. Evidence based on internal structure refers to the psychometric properties of the instrument. For example, items on a scale should be correlated as they measure the same construct, but they should not be overly correlated, as that could indicate that the items are not measuring anything unique. Generally, factor analysis and reliability estimates are used to indicate adequate factor structure and accurate and consistent responses for scores. Evidence based on relationships to other variables is usually demonstrated through some type of correlational research in which the scores on an instrument are correlated with scores on another instrument. Hence, how an instrument correlates to another instrument provides evidence that the same construct is being measured. Evidence based on consequences of testing refers to the need to document the “intended and unintended consequences” of test scores (AERA et al., 1999, p. 16). The choice of using scores on an instrument should be aligned with theory and practice.
Evidence of Validity for the Emerging Measures
To address the psychometric properties of each of the measures is outside the scope of this article. The APA promoted various measures with common psychometric properties reported extensively in research, while other measures’ psychometric properties were not as evident (Aldea, Rahman, & Storch, 2009; Allgaier, Pietsch, Frühe, Sigl-Glöckner, & Schulte-Körne, 2012; Altman, Hedeker, Peterson, & Davis, 1997; Feldman, Joormann, & Johnson, 2008; Han et al., 2009; Livianos-Aldana & Rojo-Moreno, 2001; Storch et al., 2007; Storch et al., 2009; Stringaris et al., 2012; Titov et al., 2011). From the reported measures, fairly strong psychometric properties were apparent. However, not all of the measures promoted have extensive reports (e.g., PROMIS measures). In addition, some measures do not adequately parallel the DSM-5 diagnoses that one might expect. The following sections include detailed comparisons of emerging measures and their corresponding DSM-5 diagnoses. The overall purpose of this manuscript is to identify the measures’ level of congruency with DSM-5 criteria. Thus, counselors need to be aware that certain measures may provide different information about a disorder, and therefore, counselors should make informed choices regarding whether to follow the DSM-5’s criteria. The DSM-5 criteria are a major source for providing diagnoses; and counselors should be cautious when interpreting measures, particularly when the measures are inconsistent with DSM-5 criteria.
Emotional Measures. When comparing the symptoms on the PROMIS Emotional Distress—Depression—Short Form (PROMIS Health Organization [PHO] and PROMIS Cooperative Group, 2012g) for adults to symptoms in the DSM-5 on depressive disorders, the former seems to lack many crucial symptoms for depression (APA, 2013g). Containing eight statements—each asking how often the individual has been bothered by the symptom with a time period of 7 days—the measure lacks clarity as to what depression actually looks like. Common symptoms of depression such as lack of pleasure in activities, lack of appetite, weight loss, sleep loss, fatigue and thoughts of death are not addressed. The APA (2013g) noted that irritability can be a mood shown in children with the diagnoses. The parent and pediatric measures (PHO and PROMIS Cooperative Group, 2012h; 2012i) fail to include the aforementioned mood symptom, nor do they mention thoughts of death. Therefore, the DSM-5 criteria for depression appear to be more inclusive than the PROMIS Short Form criteria.
The PROMIS Emotional Distress—Anger—Short Form, the PROMIS Emotional Distress—Calibrated Anger Measure—Pediatric, and the PROMIS Emotional Distress—Calibrated Anger Measure—Parent (PHO and PROMIS Cooperative Group, 2012a, 2012b, 2012c) are comprised of five to six short statements (e.g. “I felt angry”) completed on a 1 (never) to 5 (always) scale. Anger is included in many diagnoses, but the closest example in the DSM-5 is the chapter titled “Disruptive, Impulse-Control, and Conduct Disorders,” whose disorders can include angry moods (APA, 2013g, p. 461). Although this chapter of the DSM-5 is most likely intended for children and adolescents, all the criteria listed in the DSM-5 for angry/irritable mood from the diagnosis of oppositional defiant disorder (ODD) are included in the PROMIS measures for anger. Furthermore, because anger is present in many diagnoses in DSM-5, all measures can be helpful in providing information on anger depiction with individuals.
The PROMIS Emotional Distress—Anxiety—Short Form (PHO and PROMIS Cooperative Group, 2012d) for adults includes seven items that measure symptoms observed in an individual experiencing anxiety (e.g., “I felt anxious,” “I felt fearful”). The adult measure examines both the feelings of anxiety and fear but, unlike the child measure, omits specific places or situations where fear or anxiety is experienced. The pediatric and parent measures (PHO and PROMIS Cooperative Group, 2012e, 2012f) are more detailed, examining a few situations and places (e.g., home and school) while the adult measure (PHO and PROMIS Cooperative Group, 2012d) examines only feelings associated with anxiety (e.g., fearful, anxious, worried). When comparing anxiety measures to DSM-5 criteria, the measures lack many important criteria, particularly the adult measure which focuses on specific feelings only.
Mania is a symptom most often seen in bipolar and related disorders in the DSM-5 (APA, 2013g). The Altman Self-Rating Mania Scale (ASRM; Altman et al., 1997) is utilized for mania depiction. The five clusters focus on happiness, self-confidence, sleep, talk and activeness. When compared to the DSM-5 criteria for mania, the ASRM is lacking in certain areas such as distractibility, racing thoughts and high-risk activity involvement (APA, 2013g). Also, the ASRM does not address the importance of an irregular mood disturbance (i.e. elevated, expansive or irritable). The measure does not encompass all symptoms needed for mania, whereas the DSM-5 criteria are more expansive.
Behavioral Measures. The somatic symptom measures, which were modified from the Patient Health Questionnaire Physical Symptoms (PHQ-15; Spitzer, Williams, & Kroenke, n.d.-a, n.d.-b, n.d.-c), examine different somatic symptoms and the frequency of each symptom in a given week. The modified somatic symptom measures inform the individual and his or her clinician of the severity of symptoms such as headaches, shortness of breath and stomach pain. The main difference between the symptoms measured by the scales and those discussed in the “Somatic Symptom and Related Disorders” chapter of the DSM-5 is that the scales do not include any analysis of the excessive thoughts and feelings associated with the somatic symptoms (APA, 2013g, p. 309). The modified somatic symptom measures tell the client or clinician if and how much a symptom is present, but unlike the DSM-5 criteria, they do not focus on the individual’s actual concern over the symptom. The DSM-5 is not focused on the child population for most somatic disorders, but it does describe the most common symptoms of somatic symptom disorder as abdominal pain, headaches, fatigue and persistent nausea. Children can exhibit somatic symptoms, but they rarely worry about these symptoms before adolescence (APA, 2013g). The adult, child and parent/guardian versions of the somatic symptom measure are similar, but with two exclusions on the child and parent/guardian version (“menstrual cramps or other problems with your periods WOMEN ONLY” and “pain or problems during sexual intercourse”; Spitzer et al., n.d.-a, n.d.-b, n.d.-c).
The PROMIS—Sleep Disturbance—Short Forms (PHO and PROMIS Cooperative Group, 2012j, 2012k, 2012l) are utilized to determine sleep issues in the past week. The measures contain such questions as “my sleep was refreshing” and “I had trouble sleeping” (PHO and PROMIS Cooperative Group, 2012j, 2012k). The sleep-wake disorders in the DSM-5 include individual discontent with sleep, which can result in distress and impairment (APA, 2013g). Therefore, the PROMIS measures lack in that they do not have statements regarding whether the sleep disturbance is affecting the individual’s life negatively. The DSM-5 (APA, 2013g) does include different manifestations of certain symptoms for children (e.g., a child may struggle to fall asleep without a caregiver). Symptoms in children can occur because of particular situations such as inconsistent sleep schedule and conditioning issues. The onset of some sleep disorders happens in late adolescence or adulthood, with the exception of narcolepsy, which has an average onset in childhood and adolescence/young adulthood. Also, nightmare disorder happens most often in children and adolescence (APA, 2013g).
The repetitive thoughts and behaviors measures, which were adapted from the Florida Obsessive-Compulsive Inventory (FOCI) Severity Scale (Part B) and the Children’s Florida Obsessive-Compulsive Inventory (C-FOCI) Severity Scale, each include five items directing the individual to rate each question. The questions are focused on time, distress, control, avoidance and interference of the thoughts or behaviors (Goodman & Storch, 1994a, 1994b). The “Obsessive-Compulsive and Related Disorders” chapter in the DSM-5 examines main symptoms such as obsessions and compulsions (APA, 2013g, p. 235). Although the DSM-5 specifically identifies the symptoms as obsessions and compulsions, the adaptations of the FOCI and C-FOCI identify the symptoms as simply thoughts and behaviors. The FOCI and C-FOCI include fairly similar symptoms of obsessive-compulsive disorder with simpler terms and language. The FOCI does not include the anxiety portion, but does ask about distress. Also, the FOCI and C-FOCI do not include a specific repetitive behaviors component (Goodman & Storch, 1994a, 1994b). For the most part these two measures are very similar. Each of the five questions is focused on the same topic; the minor difference is language. For example, the adult scale asks how much distress the thoughts/behaviors cause, while the child version asks how much they bother the child. The adult measure utilizes the word work while the child measure uses the word job (Goodman & Storch, 1994a, 1994b). The measures have components similar to DSM-5 criteria, but there are inconsistencies between the two.
The Level 2—Substance Use—Adult measure, adapted from the National Institute on Drug Abuse (NIDA)-Modified ASSIST (NIDA, n.d.-a), includes 10 items that measure how often an individual used a substance in the past two weeks. The substances included are painkillers, stimulants, sedatives or tranquilizers, marijuana, cocaine or crack, club drugs, hallucinogens, heroin, inhalants or solvents, and methamphetamine. The interviewee answers from 0–4 based on how many days the substance is used. The measure does not include alcohol, tobacco or caffeine as substances (NIDA, n.d.-a). In DSM-5, the chapter “Substance-Related and Addictive Disorders” focuses on substance addictions as well as process or behavioral addictions (APA, 2013g, p. 481). The Level 2—Substance Use—Adult measure and the criteria for substance use disorders in the DSM-5 have very little in common besides the use of a substance. The DSM-5 contains topics such as intoxication, withdrawal, social impairment, risky use, behavioral issues, psychological issues and all of their related symptoms (APA, 2013g). The possible symptoms of substance use are important to examine when treating an individual who has used a substance, and therefore the expanded criteria of the DSM-5 are necessary. The parent and child versions (NIDA, n.d.-b, n.d.-c) of the substance use measures (15 items each) are longer than the adult version (10 items). The parent and child versions include tobacco, alcohol, steroids and other medicines, while the adult version does not. None of the above measures examine caffeine use (NIDA, n.d.-a, n.d.-b, n.d.-c).
The Swanson, Nolan, and Pelham, version IV (SNAP-IV; Swanson, 2011) for inattention in children aged 6–17 is an eight-item measure answered by a parent or guardian of the child. The items can be answered on a scale of 0 (not at all) to 3 (very much). The items center on the lack of attention to certain people, items and behaviors, such as organizing tasks, paying attention to details, and being distracted (Swanson, 2011). Inattention in children is included in the attention-deficit/hyperactivity disorder in the DSM-5 (APA, 2013g, p. 59). Items 1–8 on the SNAP-IV (Swanson, 2011) are worded very similarly to the inattention items in the DSM-5 (APA, 2013g), with only minor changes. The only DSM-5 item not included in SNAP-IV regards forgetfulness of daily activities (APA, 2013g). The SNAP-IV measure and the DSM-5 criteria appear to be relatively equal in diagnostic usefulness.
The irritability measures, identified as Affective Reactivity Index (ARI; Stringaris et al., 2012), for parent/guardian of child age 6–17 and child age 11–17, contain the same items and are rated either 0 (not true), 1 (somewhat true), or 2 (certainly true). Anger is a topic used in three of the seven items. Other main topics include annoyance, temper and irritability (Stringaris et. al., 2012). The irritability measures can be compared to the “Angry/Irritable Mood” section of the ODD diagnosis in DSM-5 (APA, 2013g, p. 462). The three criteria here are included in each measure, making both resources useful.
Disorder-Specific Severity Measures. The disorder-specific severity measures are similarly complementary to diagnostic criteria in the DSM-5 and are made for those who have met or are close to meeting a diagnosis. The two types of measures included are self-administered (adult and child age 11–17) and clinician-administered. Disorders included in the self-administered measures are depression, separation anxiety disorder, specific phobia, social anxiety disorder (social phobia), panic disorder, agoraphobia, generalized anxiety disorder, post-traumatic stress symptoms, acute stress symptoms, and dissociative symptoms (APA, 2014). Disorders and symptoms included in the clinician-administered measures are autism spectrum and social communication disorders, psychosis symptoms, somatic symptom disorder, ODD, conduct disorder, and nonsuicidal self-injury (APA, 2013b, 2013a, 2013f, 2013e, 2013c, 2013d).
Generally, the disorder-specific severity measures have a different time frame for meeting criteria for symptoms than the DSM-5 does and do not discuss significant distress or proportion to danger. Few, if any, differences exist between the adult and child measures. The clinician-rated measures are short and lack clarity on definitions. For example, the measures on ODD as well as nonsuicidal self-injury do not include the construct definitions (APA, 2013e, 2013d).
Self-Administered Measures. The Severity Measure for Depression—Adult and Severity Measure for Depression—Child Age 11–17 (Spitzer et al., n.d.-d, 2002), which were adapted from the Patient Health Questionnaire-9 (PHQ-9), include nine items rated from 0 (not at all) to 3 (nearly every day) with a time period of the past 7 days. The first two items on these measures are similar to the first two symptoms needed for major depressive disorder in the DSM-5, both referring to depressed mood and decreased interest or pleasure (APA, 2013g). These measures include somewhat of a weight component similar to that of the DSM-5, although the weight items on the measures examine appetite/overeating, while symptoms in the DSM-5 examine an extra component of weight loss/gain or appetite changes. The components regarding sleeping and psychomotor symptoms, fatigue, worthlessness, concentration and thoughts of death on the measures are all similar to criteria in the DSM-5, although worded differently. Irritability is added to an item on the child measure (Spitzer et al., 2002), but was not included in the adult measure (Spitzer et al., n.d.-d). The child measure’s item on eating refers to “poor appetite, weight loss, or overeating,” (Spitzer et al., 2002) whereas the adult measure does not mention weight loss (Spitzer et al., n.d.-d); similarly, one DSM-5 criterion for major depressive disorder states, “in children, consider failure to make expected weight gain” (APA, 2013g, p. 161). In spite of a few differences, the Severity Measures for Depression are mostly consistent with DSM-5 criteria for major depressive disorder.
The Severity Measure for Separation Anxiety Disorder—Adult and Severity Measure for Separation Anxiety Disorder—Child Age 11–17 (Craske et al., 2013g, 2013h) include 10 items examining the past 7 days based on a scale of 0 (never) to 4 (all of the time). The statements focus on separation and thoughts, behaviors and feelings behind the separation (Craske et al., 2013g, 2013h). The 10 items from the measure are mostly similar to criteria for separation anxiety disorder in the DSM-5 (APA, 2013g). Items 1 and 2 on the measures (which refer to terror, fear, fright, anxiety, worry and nervousness) appear similar to the distress from separation criteria in the DSM-5 with different wording. Thoughts of bad things happening, avoidance of places, physical symptoms of anxiety and difficulty sleeping are similar criteria to those in the DSM-5. The four items included in the measures but not in the DSM-5 criteria are as follows: “when separated, left places early to go home,” “spent a lot of time preparing for how to deal with separation,” “distracted myself to avoid thinking about being separated,” and “needed help to cope with separation” (Craske et al., 2013g, 2013h). Although these measures and the DSM-5 contain similar criteria for separation anxiety disorder, the measure includes items that may not be congruent to DSM-5 criteria.
The Severity Measure for Specific Phobia—Adult and Severity Measure for Specific Phobia—Child Age 11–17 (Craske et al., 2013k, 2013l) have 10 items that include five different groups of phobias, including (a) driving, flying, tunnels, bridges or enclosed spaces; (b) animals or insects; (c) heights, storms or water; (d) blood, needles or injections; and (e) choking or vomiting. The individual completing the form chooses one phobia and answers items according to that phobia on a scale of 0 (never) to 4 (all of the time; Craske et al., 2013k, 20131). The measures include more items than the criteria in the DSM-5. Items 1 and 2 (terror, fear, fright; anxiety, worry, nervousness) on the measures resemble criterion A (fear or anxiety) in the DSM-5 for specific phobia (APA, 2013g, p. 197). Physical symptoms (e.g., racing heart, tense muscles) are not included in the DSM-5 criteria. Avoidance of a situation is included both in the measures and in the DSM-5. The items in the measures which are not included in the DSM-5 are “spent a lot of time preparing for, or procrastinating about (i.e., putting off), these situations,” “distracted myself to avoid thinking about these situations” and “needed help to cope with these situations” (Craske et al., 2013k, 2013l). The specifiers in the DSM-5 (animal, natural environment, blood-injection-injury, situational and other) are similar to phobias included in the measures (APA, 2013g, p. 198). The DSM-5 states that “in children, the fear or anxiety may be expressed by crying, tantrums, freezing, or clinging” (APA, 2013g, p. 197), and this information is not included in the child version of this measure.
The Severity Measure for Social Anxiety Disorder (Social Phobia)—Adult and Severity Measure for Social Anxiety Disorder (Social Phobia)—Child Age 11–17 (Craske et al., 2013i, 2013j) are 10-item measures completed on a scale of 0 (never) to 4 (all of the time). The social situations described in the measures are the same as those described in the DSM-5 for social anxiety disorder (social phobia; APA, 2013g). Items 1, 2 and 3 on the measures are similar to criteria A and B in the DSM-5. Physical symptoms such as racing heart and tense muscles are included in the measures but are not included in the DSM-5 criteria. Avoidance of social situations is included in both the measures and the DSM-5 criteria. There are items included in the measures that are not included in the DSM-5 criteria, such as “spent a lot of time preparing what to say or how to act in social situations” and “distracted myself to avoid thinking about social situations” (Craske et al., 2013i, 2013j). One DSM-5 criterion states that “the social situations almost always provoke fear or anxiety” (APA, 2013g, p. 202), an item which is not present in the measures. In the DSM-5 there are a few differences for children with social anxiety disorder. Anxiety has to take place with peers and not only with adults. Furthermore, fear/anxiety can be expressed through crying, tantrums, freezing, clinging, shrinking or not speaking. These differences are not included in the child version of the measure (Craske et al., 2013j).
The Severity Measure for Panic Disorder—Adult and Severity Measure for Panic Disorder—Child Age 11–17 (Craske et al., 2013e, 2013f) are 10-item measures completed on a scale of 0 (never) to 4 (all of the time). The measures provide a definition and the symptoms of a panic attack in an individual (Craske et al., 2013e, 2013f). This information is similar to the definition of panic disorder in the DSM-5 (APA, 2013g). The measures include six of the 13 symptoms included in the DSM-5. Items on the measures that are not included in the DSM-5 criteria include “left situations early, or participated only minimally, because of panic attacks,” “spent a lot of time preparing for, or procrastinating about (putting off), situations in which panic attacks might occur,” “distracted myself to avoid thinking about panic attacks” and “needed help to cope with panic attacks” (Craske et al., 2013e, 2013f). The DSM-5 includes certain symptoms that the measures do not, including choking feelings, pain in chest, nausea, sensations of chills or heat, sensations of numbness or tingling, and derealization or depersonalization (APA, 2013g, p. 208). The measures have an item on sleeping issues, which was not included in the DSM-5.
The Severity Measure for Agoraphobia—Adult and Severity Measure for Agoraphobia—Child Age 11–17 (Craske et al., 2013a, 2013b) are 10-item measures to be completed on a scale of 0 (never) to 4 (all of the time). The instructions for the measures include situations on which to base the items (e.g., being in crowds or public spaces, traveling). The criteria for agoraphobia in the DSM-5 include significant distress caused by at least two of the following five situations: “being outside of the home alone,” “using public transportation,” “standing in line or being in a crowd” and being in “open spaces” and/or “enclosed spaces” (APA, 2013g, p. 217). The fear and anxiety experienced and the avoidance of situations are included in both the measures and the DSM-5 criteria. Although avoidance is included in the measures, the reason for the avoidance is not. Items included in the measures but not in the DSM-5 criteria include “had thoughts about panic attacks, uncomfortable physical sensations, getting lost, or being overcome with fear in these situations”; “spent a lot of time preparing for, or procrastinating about (putting off), these situations”; “distracted myself to avoid thinking about these situations”; and “needed help to cope with these situations” (Craske et al., 2013a, 2013b). Also, two items on physical sensations from the measures are not present in the DSM-5 criteria (APA, 2013g; Craske et al., 2013a, 2013b).
The Severity Measure for Generalized Anxiety Disorder—Adult and Severity Measure for Generalized Anxiety Disorder—Child Age 11–17 (Craske et al., 2013c, 2013d) are 10-item scales completed on a scale from 0 (never) to 4 (all of the time). Differences are found when comparing the measures to generalized anxiety disorder in the DSM-5 (APA, 2013g). The measures do not include the following DSM-5 criteria: anxiety and worry occurring for 6 months or more, difficulty controlling worry, the anxiety and worry perhaps being associated with difficulty concentrating and irritability, and the anxiety and worry causing distress (APA, 2013g, p. 222). The measures include the following items that the DSM-5 does not: “avoided, or did not approach or enter, situations about which I worry”; “left situations early or participated only minimally due to worries”; “spent lots of time making decisions, putting off making decisions, or preparing for situations, due to worries”; “sought reassurance from others due to worries”; and “needed help to cope with anxiety” (Craske et al., 2013c, 2013d). Also, item 3 on the measures (“had thoughts of bad things happening”) is similar to criterion A in the DSM-5 (“anxiety and worry . . . about a number of events or activities”) with different wording (APA, 2013g, p. 222; Craske et al., 2013c, 2013d).
The National Stressful Events Survey PTSD Short Scale (NSESSS; Kilpatrick, Resnick, & Friedman, 2013c) contains nine items and is to be completed on a scale of 0 (not at all) to 4 (extremely). The criteria for post-traumatic stress disorder (PTSD) in the DSM-5 include a list of possible stressful events and situations (APA, 2013g). The NSESSS does not include a list of stressful events and situations for the individual. Criteria and items that are the same or similar on the NSESSS and in DSM-5 PTSD criteria include flashbacks, emotional (NSESSS) or psychological distress (DSM-5), avoidance, negative feelings about self, distorted cognitions and blame, negative emotional states, loss of interest in activities, anger and irritability, self-destructive behavior, hypervigilance and startle response (APA, 2013g; Kilpatrick et al., 2013c). The items/criteria may be worded and/or organized differently but they have the same meaning. Although all items on the NSESSS are included in the DSM-5’s criteria for PTSD, the DSM-5 includes additional criteria beyond what the NSESSS measures, which suggests the DSM-5 as being more thorough of the two, and indicates the inconsistencies of the NSESSS when compared to the DSM-5 criteria. The following criteria from the DSM-5 are not included in the NSESSS: dreams, physiological reactions, dissociative amnesia, detachment/estrangement from others, inability to experience positive emotions, concentration issues and sleep issues. There are notes in the DSM-5 for application to children. Children may partake in recurring play/reenactment having to do with the traumatic event. Dreams with unrecognizable content may occur (APA, 2013g). The criteria above were not included in the child version of the NSESSS (Kilpatrick, Resnick, & Friedman, 2013d). Also, the DSM-5 has a different section for children 6 and under, but the NSESSS is to be completed by children 11–17 (APA, 2013g; Kilpatrick et al., 2013d).
The National Stressful Events Survey Acute Stress Disorder Short Scale (NSESSS; Kilpatrick et al., 2013a) for severity of acute stress symptoms includes seven items and is to be completed on a scale of 0 (not at all) to 4 (extremely). Six out of the seven items on this measure are the same as those on the measure for PTSD above. Items that are also included in acute stress disorder in the DSM-5 are flashbacks, emotional (NSESSS) or psychological distress (DSM-5), detachment, avoidance, hypervigilance, startle response and irritability/anger (APA, 2013g). Similar to the NSESSS for PTSD, all seven items on the NSESSS for acute stress disorder are included in the DSM-5 criteria, but certain DSM-5 criteria are not included in the NSESSS. The criteria not included are as follows: dreams, inability to experience positive emotions, dissociative amnesia, sleep disturbance and concentration issues. There are notes in the DSM-5 for application to children. Children may partake in recurring play/reenactment having to do with the traumatic event. Dreams with unrecognizable content may occur. The criteria above were not included in the child version of the NSESSS (Kilpatrick et al., 2013b). Neither of the NSESSS measures fully assess an individual for the DSM-5 criteria for PTSD or acute stress disorder.
The Brief Dissociative Experiences Scale (DES-B)—Modified (Dalenberg & Carlson, 2010a) has eight items and is completed on a scale of 0 (not at all) to 4 (more than once a day) in the past 7 days. When comparing this measure to dissociative disorders in the DSM-5, it is hard to find a specific criterion that matches closely to items on the scale (APA, 2013g, p. 291). The closest criterion is found under dissociative identity disorder (DID; APA, 2013g). Although the wording is different, disruption of identity and gaps in recollections are both present in the DES-B and DSM-5 criteria for DID. Some items on the DES-B are also included in depersonalization/derealization disorder (APA, 2013g, p. 302). Both depersonalization and derealization symptoms are included in DES-B. There is one note under DID in the DSM-5 applicable to children: symptoms in children are not better justified by imaginary or fantasy play. This is not included in the child version of the DES-B (Dalenberg & Carlson, 2010b). Although items included in the measures are present in DSM-5 criteria, overall, the measures are inconsistent with DSM-5 criteria.
Clinician-Rated. The Clinician-Rated Severity of Autism Spectrum and Social Communication Disorders is a measure that assesses “the level of interference in functioning and support required as a result of: a) any social communication problems AND b) any restricted interests and repetitive behaviors” (APA, 2013b). The two disorders included are autism spectrum disorder (APA, 2013g, p. 50) and social (pragmatic) communication disorder (APA, 2013g, p. 47). The clinician must choose one of these disorders. The clinician rates the two items above (social communication and restricted interests /repetitive behaviors) based on levels 0 (none), 1 (mild; requiring support), 2 (moderate; requiring substantial support), and 3 (severe; requiring very substantial support). The measure does not go into detail about these disorders’ diagnostic criteria, but the DSM-5 offers a detailed account (APA, 2013b, 2013g). Besides simply stating the two issues above, the measure fails to include specific criteria from the DSM-5.
The Clinician-Rated Dimensions of Psychosis Symptom Severity (APA, 2013a) is a measure that rates symptoms of psychosis based on presence and severity in the last 7 days. The eight domains included in the measure are hallucinations, delusions, disorganized speech, abnormal psychomotor behavior, negative symptoms (restricted emotional expression or avolition), impaired cognition, depression and mania. The clinician rates the symptoms either 0 (not present), 1 (equivocal), 2 (present, but mild), 3 (present and moderate) or 4 (present and severe; APA, 2013a). According to the DSM-5, the five main features of psychotic disorders include delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms (APA, 2013g, pp. 96, 99). These main features are included in the measure as well as three others. Schizophreniform disorder (APA, 2013g, p. 96) and schizophrenia (APA, 2013g, p. 99) include the five main features for criteria in the DSM-5 but not the last three included in the measure, which are impaired cognition, depression and mania (APA, 2013a). Other disorders, such as depressive or bipolar disorders with psychotic features, would include either a depressive or manic symptom (APA, 2013g, 2013a). Because the measure assesses psychosis symptoms that are consistent with DSM-5, this measure could be useful in determining severity but not consistent with any specific diagnosis.
The Clinician-Rated Severity of Somatic Symptom Disorder (APA, 2013f) includes three items in which the clinician rates somatic symptoms based on presence and severity in the last 7 days. The scale is to be completed from 0 (not at all) to 4 (very much). The main themes of the three questions are concerns, anxiety, and time and energy (APA, 2013f). The somatic symptom disorder in the DSM-5 includes the three themes above in criterion B with similar wording, but also includes criteria not present in the measure (APA, 2013g, p. 311), so the measure is again inconsistent with DSM-5 criteria.
The Clinician-Rated Severity of ODD (APA, 2013e) and the Clinician-Rated Severity of Conduct Disorder (APA, 2013c) both include only one item to assess based on the presence and severity of any ODD or conduct disorder symptoms (APA, 2013g). The scales are to be completed from level 0 (none) to level 3 (severe). The items simply state, “Rate the level or severity of the OPPOSITIONAL DEFIANT problems that are present for this individual” (APA, 2013e) and “Rate the level or severity of the conduct problems that are present for this individual” (APA, 2013c). The criteria for diagnosis are not listed in the measures but can be found under ODD and conduct disorder in the DSM-5 (APA, 2013g). Although the criteria for both are absent in the measures, APA refers clinicians to the DSM-5, which suggests that the measures completely parallel the diagnostic criteria.
The Clinician-Rated Severity of Nonsuicidal Self-Injury (APA, 2013d) is a one-item measure that examines the presence and severity of any nonsuicidal self-injury problems that have happened in the past year. The scale is to be completed based on five levels, including 0 (none), 1 (subthreshold), 2 (mild), 3 (moderate), and 4 (severe). The item simply states, “Rate the level or severity of the NONSUICIDAL SELF-INJURY problems that are present for this individual” (APA, 2013d). The symptoms are not listed but can be found under nonsuicidal self-injury in the DSM-5 (APA, 2013g, p. 803). Similarly to the previous measures stated, the APA directs clinicians to the DSM-5, which again indicates an alignment to diagnostic criteria.
Implications for Counseling Practice
The APA (2013g) endorsed dimensional assessment to be used in conjunction with categorical diagnoses. An effort to establish measurement protocols in a process often deemed rather subjective is laudable. The APA indicated that the assessment system was an “emerging” (2013g, p. 729) system, which indicates a rather circumspect decision by the APA. The DSM system represents a system of classifying diagnoses, whose current framework is 20–30 years old and widely established (Jones, 2012). Given the influence of the DSM system of diagnosis (e.g., reimbursement, research studies, treatment planning), the publication of the emerging measures that fail to meet basic standards of testing and measurement could be confusing to counselors expecting that scores of the emerging measures would provide consistent and accurate information about severity and be consistent with diagnostic classifications in the DSM-5.
The presence of validity evidence across the emerging measures is inconsistent, based on erratic reporting of psychometric information and lack of alignment with diagnostic criteria, such as what was documented regarding the disorder-specific severity measures. Although many of the measures were validated for clinical use, other measures lack this information. Perhaps the most basic critique of the system is that the publication of these measures lack alignment with the very diagnostic categories they are supposed to evaluate.
Evidence based on test content (AERA et al., 1999) is perhaps the most basic type of evidence for providing validity evidence of measures. The process entails that instruments that are developed be aligned with published research and expert review. Hence, the presence of dimensional measures that are supposed to align with the DSM-5 classification system but fail to be comprehensive in the breadth of symptoms covered could be a serious limitation of these emerging measures.
Professional counselors should be cautious in the adoption of the dimensional measures. Many quality measures already exist that adequately align with the categorical diagnostic system of the APA. For example, in the development of the Beck Depression Inventory (BDI)-II, Beck, Steer, and Brown (1996) updated the initial BDI to align with the diagnostic symptoms of depression used in the DSM-IV. The APA should follow similar processes in terms of content alignment and the collection and analysis of data to provide evidence of psychometric properties; counselors must be aware that adherence to this process was not systematically implemented. Both the CCSMs and severity measures were designed to review general symptoms commonly apparent across a broad range of clients and to “be administered both at initial interview and over time to track the patient’s symptom status and response to treatment” (APA, 2013g, p. 733). However, the variability with respect to the diagnostic classifications and absence of psychometric properties limits the potential for these measures to provide accurate and valid assessments.
The measures may be helpful in confirming clinical impressions or identifying potential problem areas that warrant further exploration. To some degree, however, counselors should be aware of potential ethical dilemmas that could arise from using the emerging measures endorsed by the APA. According to the American Counseling Association (ACA), “counselors have a responsibility to the public to engage in counseling practices that are based on rigorous research methodologies” (2014, p. 8). Clearly, the extent to which the published emerging measures represent rigorous research is at issue. APA does identify the measures as “emerging” (2013g, p. 729), thereby acknowledging the preliminary nature of the dimensional assessments. From a public health standpoint, the consequences of basing diagnoses or justifying clinical care or improvement solely on the emerging measures could be egregious. As third-party payers and managed care companies scramble to adopt the new classification system, the presence of the emerging measures could be mistaken as an endorsement for their adoption by organizations (e.g., managed care companies) that lack the understanding of the measurement and evaluation principles. The presence of the emerging measures in the DSM-5 presents an incomplete system that may not augment comprehensively the categorical system of diagnosis currently endorsed by the APA (2013g). Counselors using the emerging measures should employ other well-established measures and protocols to corroborate their clinical impressions and findings.
Counselors should be careful when interpreting the results of instruments that lack adequate empirical data to support respondent results; they should also qualify any conclusions, diagnoses, or recommendations that are based on assessments or instruments (ACA, 2014, p. 12). When emerging measures are used for diagnostic classification or to denote changes in symptoms or distress, counselors should identify the extent to which the findings from the dimensional assessment match the clinical impressions or findings from other assessment tools. Assessment tools, in general, provide information that should not stand alone (Balkin & Juhnke, 2014), and the use of the dimensional measures is not an exception to this rule.

Major depressive disorder, bipolar I disorder and schizophrenia are chronic conditions, and adults who have these diagnoses often benefit from mental health treatment throughout their lives. The recent fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) included changes to many diagnoses. Consequently, counselors need to understand the changes and revise their diagnostic practices accordingly. Changes affect new clients being diagnosed for the first time as well as long-term clients who were initially diagnosed many years ago. This manuscript provides an explanation of changes to major depressive disorder, bipolar I disorder and schizophrenia. Case examples illustrate implications for counselors who work with clients who have these three serious and chronic mental illnesses. Counselors, following best practice guidelines and the American Counseling Association’s ethical mandate, can take advantage of this opportunity to ensure that clients understand their mental health conditions and that documented diagnoses are accurate and thorough.
Keywords: major depressive disorder, bipolar I disorder, schizophrenia, DSM-5, diagnoses, chronic mental illness
Major depressive disorder, bipolar I disorder and schizophrenia are chronic mental health conditions. Adults who have these diagnoses often benefit from mental health treatment from counselors, psychiatrists and other clinicians throughout their lives. A new edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association [APA], 2013) has been released. The changes therein impact both new clients who present for initial assessment and also clients who have been in treatment for chronic conditions. A thorough understanding of the implications for revising existing diagnoses will help counselors provide quality services to clients who need ongoing support. Counselors also are responsible for helping clients understand their diagnoses, so the release of the DSM-5 is an opportunity to ensure that both new clients and clients in long-term treatment have an opportunity to ask questions about their conditions (American Counseling Association [ACA], 2014). Using the full terminology available in the DSM-5 (e.g., defined diagnoses instead of other specified umbrella diagnoses and including specifiers to highlight key features of the disorder) will help establish the new common language so that clinicians and clients can all communicate effectively about treatment. To illustrate how counselors can use the DSM-5 to best serve clients who have major depressive disorder, bipolar I disorder and schizophrenia, this article provides information about each disorder, a description of the changes from the DSM-IV-TR to the DSM-5, case examples and conclusions.
Major Depressive Disorder
Nearly 16 million adults in the United States experience a major depressive episode each year (Substance Abuse and Mental Health Services Administration [SAMHSA], 2013), as defined by the DSM-IV-TR (APA, 2000). Individuals who experience major depressive disorder suffer from impairment in every part of their lives, including relationships, functioning at work and self-care. When symptoms of depression increase, individuals may not feel motivated to spend time with others. They may feel no pleasure in previously enjoyable activities and experience interactions with others as draining. Similarly, a previously motivated and engaged employee may seem distracted or disconnected at work and absenteeism may become a problem. In addition to problems in relationships and at work, self-care also is impacted by major depression. Time and energy for healthy habits such as exercise and meal preparation may be lost. In severe cases, a lack of attention to basic hygiene may be observable.
The severity and length of symptoms can vary tremendously for individuals with major depressive disorder. Some people never experience remission while others may enjoy years without symptoms (National Institute of Mental Health [NIMH], n.d.-a). The longer the period of remission, the lower the likelihood of a recurrence (APA, 2013). For those individuals who have more severe episodes, a history of multiple previous episodes, or were first diagnosed at a younger age, lifelong mental health treatment may be necessary to increase quality of life (APA, 2013).
Treatment. Almost 11 million people diagnosed with major depressive disorder sought treatment in 2012, which was approximately 68% of those diagnosed with the disorder (SAMHSA, 2013; based on DSM-IV-TR criteria). The most common forms of treatment are medications (e.g., antidepressants), psychotherapy/counseling or a combination of the two. In 2012, 45% of all individuals who had a major depressive episode used a combination of psychotherapy/counseling and medications, while 14.1% used psychotherapy/counseling only, and 6.6% used medication only (SAMHSA, 2013). More than half of the individuals who received medication for their major depressive episode did so from their general practitioner (SAMHSA, 2013). For those who sought psychotherapy/counseling, many accessed outpatient counseling at a mental health clinic or private practice in the community. About .8% reported they were hospitalized at some point in the year (SAMHSA, 2013). Others may have received treatment that included more intensive interventions such as case management to help with access to services and subsistence or day treatment to provide all-day support and supervision when needed. Because such a small percentage of clients seek psychotherapy/counseling alone (SAMHSA, 2013), it is likely that counselors who work with clients who have major depressive disorder do so as part of a treatment team. Counseling is an essential part of treatment, as there is ample empirical evidence for its effectiveness, particularly cognitive-behavioral and interpersonal techniques (e.g., Paradise & Kirby, 2005).
Bipolar I Disorder
Bipolar I disorder affects roughly .6% of the population (APA, 2013). It is a lifelong disorder, as nearly all of the individuals who have one manic episode will have multiple episodes in their lifetime (APA, 2013). Symptoms of bipolar I disorder can be detrimental to relationships, daily functioning and financial stability of the individual who is diagnosed with the disorder. The cyclical nature of bipolar I disorder leads to instability, as the episodes of depression, mania and remission each have a different impact on the individual’s life. During episodes of depression, the impact is similar to that caused by major depressive disorder, as described above. In contrast, some individuals with bipolar I disorder report enjoying manic episodes as they escalate because of improved mood, energy and productivity. However, elevated mood often comes with dangerous grandiosity, distractibility and impulsivity. During periods of remission when symptoms are mild or absent, the person may attempt to repair the consequences of their manic episodes (e.g., excessive shopping) and depressive episodes (e.g., neglected chores).
Few people seek treatment on their own during manic episodes. Initiating or expanding treatment during a manic episode is important to prevent irreparable damage and to ensure safety. Grandiosity combined with risky behaviors can lead to physical injuries and property damage, and the euphoria of elevated mood can quickly shift to anger and irritability. For more than half of individuals with bipolar I disorder, depressive episodes follow manic episodes (APA, 2013), which is especially dangerous to the individual if he or she is not in a secure treatment setting.
Treatment. Roughly two-thirds of those diagnosed with bipolar I disorder receive treatment each year (Merikangas et al., 2007). The most common form of treatment is medication, including mood stabilizers, atypical antipsychotics and antidepressants (NIMH, n.d.-b). While many of these medications are effective in managing symptoms, some can have serious side effects resulting in additional medical risks such as liver or kidney issues. These risks, in addition to lack of insight into illness, preference for manic episodes, and comorbid personality or addictive disorders can lead to noncompliance (Colom et al., 2000).
In treating bipolar I disorder, individual therapy and family counseling may be helpful in developing client interpersonal skills and increasing quality of life (NIMH, n.d.-b; Steinkuller & Rheineck, 2009). There is clear empirical evidence suggesting that individuals who participated in psychotherapy more frequently and for a longer duration in addition to using medication had a better prognosis than those who participated in fewer sessions over a shorter period of time (NIMH, n.d.-b.; Steinkuller & Rheineck, 2009). These individuals appeared to recover more quickly, have fewer relapses and require fewer hospitalizations.
Schizophrenia
About 1% of Americans have schizophrenia (NIMH, n.d.-c). Only one in five people diagnosed with the disorder return to the level of functioning they had before onset. Therefore, schizophrenia is often a pervasive and lifelong disorder that can severely impair daily functioning. Individuals with schizophrenia may have difficulty completing tasks, focusing on assignments and processing information. Because onset of schizophrenia is typically in early adulthood, a person’s ability to make educational progress and develop necessary skills to obtain a job or receive a degree may be limited (NIMH, n.d.-c). The lack of income threatens stable housing and basic needs. Therefore, individuals diagnosed with schizophrenia are likely to require financial assistance from family or public funding sources.
Treatment. The most common form of treatment for schizophrenia is medication. Antipsychotic medications focus on managing symptoms by reducing the severity and frequency of hallucinations and delusions. However, not all medications work for all individuals, and many can have significant side effects such as blurred vision, tremors, drowsiness, sensitivity to sunlight and tardive dyskinesia (NIMH, n.d.-c). Because of these side effects and the cognitive impairments inherent in the disorder, medication compliance is a problem, as individuals will sometimes skip doses or discontinue medications altogether.
Other forms of treatment are recommended in conjunction with medication, such as counseling and psychoeducation to teach individuals skills for daily functioning, interacting with others, self-care and employment (NIMH, n.d.-c). Person-centered approaches may be effective, as a lack of insight into the illness may cause clients to become skeptical about treatment (Kreyenbuhl, Nossel, & Dixon, 2009; NIMH, n.d.-c).
In summary, roughly one in 10 Americans will experience major depressive disorder, bipolar I disorder or schizophrenia each year, and two-thirds of those will seek treatment for their conditions (Merikangas et al., 2007; SAMSHA, 2013). Counselors who provide essential services to clients may have first made the diagnosis long ago and likely are part of a treatment team. With the release of the new version of the DSM, best practice is to review and revise diagnoses for all clients to ensure accuracy. Each change to major depressive disorder, bipolar I disorder and schizophrenia is described below.
Changes from DSM-IV-TR to DSM-5
Major Depressive Disorder
The mood disorders section in the DSM-IV-TR began with criteria for mood episodes (e.g., depressive, manic, hypomanic; APA, 2000). The mood episodes were later included in the diagnostic criteria for mood disorders. The DSM-5 has a different format. The mood disorders are separated into two sections: depressive disorders, and bipolar and related disorders. In addition, the DSM-5 lists complete criteria for each disorder in one place, rather than separating the mood episodes from the rest of the criteria for each disorder (e.g., major depressive disorder).
Major depressive disorder now includes a streamlined list of symptoms and examples of each so that clinicians may better understand the intended criteria. Part A of the diagnostic criteria did not change: “Five (or more) of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure” (APA, 2013, p. 160). The nine symptoms that follow are very similar to the symptoms listed in the DSM-IV-TR. The first symptom focuses on depressed mood and is the hallmark of the disorder. The example “hopeless” was added to increase clarity about the way clients may describe how they feel. The requirement of clinically significant distress did not change, nor did the verbiage about symptoms being caused by a medical condition or better explained by other disorders.
A significant change was made to criterion E of DSM-IV-TR, often called the bereavement exclusion. The previous rule was that major depressive disorder could not be diagnosed following the death of a loved one or other loss unless the symptoms persisted for 2 months (as opposed to the typical 2-week required duration). The DSM-5 states that responses to loss may include feelings and behaviors that match those listed in the criteria for major depressive disorder. Although the reaction may be considered understandable given the recent loss, if criteria for the disorder are met, the diagnosis may be given regardless of the circumstances. Representatives from the depressive disorders work group explained their rationale for this change at the 2013 American Psychiatric Conference (Zisook, 2013). They noted that the criteria for diagnosis should be defined without regard to the cause of the symptoms. Many things can cause or exacerbate depressive symptoms. Most individuals who suffer losses (e.g., death of a loved one, divorce, unemployment) will not experience symptoms severe enough to merit diagnosis (Zisook, 2013). Severe depressive symptoms, such as those required for diagnosis of major depressive disorder, merit clinical attention regardless of external causes in the individual’s life. The DSM-5 gives the counselor the discretion to diagnose major depressive disorder in grieving clients if the symptoms have been met for 2 weeks, rather than requiring 2 months of suffering as noted in the DSM-IV-TR.
Perhaps more relevant to those clients who have long been diagnosed with major depressive disorder, the DSM-5 included changes to the specifiers. Single episode, recurrent, mild, moderate and severe are again included with different numerical codes for each. One change is that psychotic features can now be added to mild, moderate or severe levels. Specifiers about seasonal pattern, catatonia, melancholia, and atypical features remain with expanded descriptors in some cases. Postpartum was changed to peripartum because symptoms often emerge during pregnancy, which would not fit the DSM-IV-TR specifier of postpartum, but is important nonetheless. The term peripartum means during the pregnancy or in the 4 weeks following delivery, so this specifier can be used in both cases. In addition, new specifiers were added: with anxious distress and with mixed features. Both are described below.
The specifier with anxious distress is to be used when the client experiences two or more of the following symptoms most days: feels tense, feels unusually restless, worry disrupts concentration, fears something bad will happen, or worries about losing control of oneself. The severity of the anxious distress specifier also is noted, using mild, moderate, moderate-severe and severe. This specifier was added because clinicians frequently described the presence of some symptoms of anxiety in their clients who have major depressive disorder. Often, the threshold is not met for a comorbid anxiety disorder diagnosis but the symptoms are significant nonetheless. Clients with anxious distress are more likely to attempt suicide and may require more intensive treatment than those with depression alone; therefore, it is essential that counselors note these symptoms in the diagnosis (APA, 2013; Goldberg, 2013).
The specifier with mixed features applies when clients have subthreshold hypomania most days in addition to symptoms of depression. For example, the criteria require three of the following symptoms to be present nearly every day during most of the days in the depressive episode: elevated mood, grandiosity, pressured speech, racing thoughts, increased energy, involvement in risky activities or decreased need for sleep. This specifier is important to note because clients who have major depressive disorder with mixed features are more likely to develop bipolar I or bipolar II disorder (Coryell, 2013). Because treatment for the bipolar disorders is often different from treatment for major depressive disorder, noting the mixed features is important to help clinicians track changes in the client’s symptoms closely.
A final change in DSM-5 that affects multiple diagnoses, including major depressive disorder, is the inclusion of cross-cutting symptom measures (APA, 2013). The goals of these instruments are to help clinicians understand client symptoms more effectively, to identify co-morbidity of symptoms and to track changes in symptoms over time (Clarke, 2013). The Level 1 Cross-Cutting Symptom Measure–Adult is a self-report measure for adults to provide clinicians with information about the presence of symptoms. This measure also can be completed by an informant if the individual lacks the capacity to do so (APA, 2013). The measure consists of 23 questions related to 13 domains such as depression, anger and anxiety. To complete the measure, an individual rates the presence of symptoms over the past 2 weeks using a 5-point Likert scale (0 = none or not at all to 4 = severe or nearly every day). For most of the domains, a rating of mild or greater on any item is an indicator for a clinician to conduct a more detailed assessment (APA, 2013). However, for suicidality, psychosis and substance use, endorsement of any symptoms necessitates further investigation. Further assessment may include the use of the level 2 cross-cutting symptom measures. These domain-specific instruments are not included in DSM-5, but are available online at http://psychiatry.org/practice/dsm/dsm5/online-assessment-measures (APA, 2014). The cross-cutting measures can be administered numerous times for initial and ongoing assessment. Clinical trials revealed that the measures are easy to use and incorporate into daily practice and provide meaningful information (Clarke, 2013). Clients who participated in the clinical trials felt better understood by their clinicians when they used these measures (Clarke, 2013). Therefore, cross-cutting measures in the DSM-5 can be excellent information-gathering tools that counselors can use to make informed diagnostic and treatment decisions.
Bipolar I Disorder
As described above, bipolar I disorder is now included in a separate section for bipolar and related disorders, and the complete diagnostic criteria list is found in one place (i.e., APA, 2013, p. 123). The core prerequisite for bipolar I disorder continues to be the presence of at least one manic episode, and several of the criteria for the manic episode were revised to increase clarity.
For example, criterion A for a manic episode in the DSM-IV-TR describes “a distinct period of abnormally and persistently elevated, expansive, or irritable mood, lasting at least 1 week (or any duration if hospitalization is necessary)” (APA, 2000, p. 362). In the DSM-5, the phrase “and present most of the day, nearly every day” was added to clarify how frequently the mood state must be present (APA, 2013, p. 124). Similarly, in criterion B, the DSM-5 specifies that the elevated, expansive or irritable mood must “represent a noticeable change from usual behavior” (APA, 2013). In the list of seven symptoms under criterion B, two were revised for greater clarity. The DSM-5 notes that distractibility can be either reported or observed. Psychomotor agitation is defined as “purposeless non-goal-directed activity” (APA, 2013, p. 124).
Criterion C from the DSM-IV-TR states that the episode in question must truly be a manic episode, not a mixed one. Mixed episodes were removed entirely from the DSM-5 as they were exceedingly rare, and instead a specifier denoting mixed features was added (Coryell, 2013). Additionally, the exclusion for manic-like episodes caused by antidepressant treatment was also removed. That is, in the DSM-IV-TR, if the manic symptoms follow antidepressant treatment such as medication, light therapy or electroconvulsive treatment, they are not considered symptoms of a true manic episode. In the DSM-5, that exclusion is removed. If a client displays symptoms that meet the criteria for a manic episode, the diagnosis can be given regardless of previous antidepressant treatment.
Additional descriptors also were added to the criteria for a hypomanic episode, although the diagnosis continues to describe individuals who display manic symptoms, but do not show clinically significant impairment. The elevated, expansive or irritable mood must be present for 4 consecutive days and for most of the day. The antidepressant exclusion also is removed from the hypomanic episode criteria, but clinicians are cautioned not to interpret irritability or agitation as sufficient for diagnosis. Bipolar I specifiers for severity and course remain the same, except that the psychotic features specifier is now coded separately from severity, as described above in major depressive disorder. Similarly, the specifiers with anxious distress and with mixed features were added to the bipolar disorders.
Schizophrenia
How schizophrenia is conceptualized did not change from the DSM-IV-TR to the DSM-5, but the criteria for the diagnosis did change significantly. In the DSM-IV-TR, criterion A stated that two or more of the following symptoms must be present for at least 1 month unless successfully treated: delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, or negative symptoms. An additional note permitted diagnosis with only one symptom of delusions or hallucinations if bizarre or persistent. The DSM-5 increases the diagnostic threshold by requiring the presence of delusions, hallucinations or disorganized speech (as opposed to the diagnosis being possible based on disorganized behavior and negative symptoms alone) and removing the single symptom option for meeting criterion A. The duration requirement remains the same as in DSM-IV-TR: at least 1 month of active symptoms in a time period of at least 6 months of impairment. Criterion D remains the schizoaffective disorder and mood disorder exclusion, but the text was revised to define how frequently manic or depressive symptoms must be present in order to meet full criteria. The DSM-5 specifies that mood symptoms must be present for at least half of the total duration of active and residual psychotic phases in order to be considered (APA, 2013).
The specifiers about the episodic or continuous symptoms and remission were changed in the DSM-5 and the subtypes were removed entirely. Course specifiers were revised for clarity and now include descriptors for first episode, multiple episodes, continuous or unspecified. These specifiers are not used until the disorder has been present for 1 year. In the DSM-5, the subtypes are not included as part of the diagnosis. For example, DSM-IV-TR language such as 295.30 schizophrenia, paranoid type is no longer used. The types are still described under the delusional disorder criteria, but the differentiated types of schizophrenia are no longer endorsed. Almost all schizophrenia diagnoses are now coded 295.90 schizophrenia, except for those individuals who have catatonia, and their diagnoses are coded 293.89. In the DSM-5, the Clinician-Rated Severity of Psychosis Symptoms Severity scale was added (APA, 2013). The rating scale and other instruments are available online at http://psychiatry.org/practice/dsm/dsm5/online-assessment-measures. Clinicians are instructed to rate the presence of symptoms over the previous 7 days across eight dimensions. The dimensions, rated from 0 (no presence) to 4 (severe and present), are hallucinations, delusions, disorganized speech, abnormal psychomotor behavior, negative symptoms, impaired cognition, depression and mania. During a presentation on the DSM-5 (Malaspina, 2013), representatives from the schizophrenia spectrum and other psychotic disorders work group explained that symptoms for individuals with schizophrenia can change over time. Therefore, the scale was designed to help clinicians note their detailed observations of the client and track changes in symptoms across time.
Case Examples
Some of the changes previously described are minor and do not result in revisions to the core diagnoses of clients with these disorders. However, some changes might impact diagnoses, and others might alter the way we describe the disorder or the name of the disorder itself. As with the conversion from the DSM-III-R (APA, 1987) to the DSM-IV (APA, 1994), the process will be ongoing. The cases below illustrate possible changes that counselors, supervisors and counselor educators can make immediately in their practices.
Martha: Major Depressive Disorder
Martha is a 47-year-old married mother of two. She works part-time as a real estate agent and is active in her Episcopal church. Her husband spends long hours at work and is often required to travel out of town. Her two adult children live nearby. Her father is deceased and her mother’s health is unstable, although she lives at a local assisted living facility.
Martha’s depression was first recognized by her family doctor when she was 23. He was not familiar with the DSM (DSM-III-R at that time), but recognized symptoms of sadness, hopelessness, emptiness and fatigue. He began prescribing her a relatively new drug called Prozac. Martha experienced improvement immediately. For the next 6 years Martha’s family doctor managed her depression with occasional dosage increases and biannual checkups. Just before her 30th birthday, Martha experienced her first severe depressive episode and attempted suicide. She had delivered her second child three weeks prior, and her husband found her after she cut her wrists.
Martha was hospitalized and received her first full mental health evaluation. Using the DSM-IV criteria, she was diagnosed with 296.33 major depressive disorder, recurrent, severe without psychotic features, with postpartum onset. Recurrent was given because of her self-reported symptom and treatment history. Her present symptoms far exceeded the minimum required for diagnosis, so the episode was considered severe. Martha was coherent, denied hearing voices or seeing images, and showed no evidence of delusions, so no psychotic features were noted. The suicide attempt occurred 3 weeks after delivery and depressive symptoms had been present for at least a week at that point; therefore, Martha met criteria for the postpartum onset specifier. Martha also experienced anxiety about caring for her children and managing her life but did not meet criteria for an anxiety disorder. Following discharge from the hospital, Martha continued to see the psychiatrist she met while hospitalized and began seeing a licensed professional counselor. Martha worked well in counseling and experienced long periods of remission and several more moderate depressive episodes in the 17 years that followed. She maintained regular appointments with her psychiatrist for medication management and sought counseling at times of increased depression or stress.
Presently, Martha has just resumed seeing a licensed professional counselor. She describes sadness, low energy, hopelessness, limited pleasure, insomnia, and stressors related to aging, her family relationships and her mother’s failing health. Her psychiatrist adjusted her medication and suggested that she resume counseling for additional support. Although the counselor has worked with Martha previously, the resumption of services is a great opportunity to revisit her diagnosis.
At this time, Martha’s core diagnosis of major depressive disorder, recurrent remains appropriate. Upon further exploration of Martha’s symptoms, the counselor finds that seven symptoms are present; therefore, Martha’s depressive episode is considered moderate. The new specifier with moderate anxious distress is also appropriate for inclusion because of Martha’s reported stressors. Martha feels tense and restless nearly every day. She worries about her children, her health, and her mother, and has difficulty focusing on her work and household tasks. She describes the feelings of depression as present all day, every day, and the stress, worry, and tension as present nearly every day, particularly when she attempts to “face reality” and engage with others or accomplish tasks around the house. A review of Martha’s history shows that anxious distress may have always been present during her depressive episodes. It was noted during her hospitalization and during previous counseling services, but had not reached the severity level necessary for an anxiety disorder diagnosis. Noting these important symptoms using the specifier may help Martha get the treatment she needs. Using the cross-cutting symptom measures to track her symptoms of depression and anxiety may be helpful as the counselor works to find the most effective ways to facilitate progress on Martha’s goals.
During Martha’s 24 years of treatment, she has had several slightly different diagnoses. Her first unspecific depression diagnosis from the family physician was further identified by the evaluation she had while an inpatient using the DSM-IV criteria for 296.33 major depressive disorder, recurrent, severe without psychotic features, with post-partum onset. Martha’s current diagnosis of 296.32 major depressive disorder, recurrent, moderate, with moderate anxious distress is reflective of both her history and current presentation.
Bo: Bipolar I Disorder
Bo is a 32-year-old single male. He lives alone with the support of his mother and brother. He has held numerous entry-level jobs for short time periods. Presently, he is unemployed and receiving Social Security Disability benefits. He receives treatment through a local mental health center. His current treatment program is called Program of Assertive Community Treatment (PACT; National Alliance on Mental Illness, 2014) and includes psychiatry, counseling, case management and vocational rehabilitation services. Some services occur at the local mental health center and some occur in his home or in the community.
Bo was first diagnosed (per the DSM-IV-TR) with 296.90 mood disorder, not otherwise specified when he was 24. During adolescence, Bo had a history of drug and alcohol use, academic and behavioral problems at school, and minor legal infractions. At age 22, Bo had a stable job, one year of sobriety, and lived alone for the first time. After 3 days of no returned phone calls, Bo’s brother began a search and finally found him in an apparent manic state. He was rambling enthusiastically about a new business in media promotions. He had drawings and notes scattered across his apartment with what appeared to be logos for the business. Bo told his brother that he would make millions of dollars with his connections in the music industry. Bo’s brother was concerned given that Bo had no such relationships. With just a little prodding, Bo revealed he had already spent his life savings and sold his motorcycle to get the business started and needed to borrow more money to “make it happen.” He became furious and destructive when his brother challenged his ideas. Bo’s brother was alarmed and took him to the local emergency room for an evaluation.
The emergency clinician met with Bo and determined that although some of his symptoms matched those for a manic episode, his vague symptom history and relatively short duration of illness precluded diagnosis of bipolar I disorder at that time. Bo was diagnosed with 296.90 mood disorder, not otherwise specified and referred to a crisis stabilization program for treatment and further evaluation. Bo was resistant to treatment because he did not believe his behavior to be inappropriate. After 4 days in crisis stabilization, Bo’s mood changed dramatically and he entered a major depressive episode. He expressed suicidal intent and was hospitalized. His diagnosis was revised to 296.53 bipolar I disorder, most recent episode depressed, severe without psychotic features (per DSM-IV-TR at the time).
Over the next 10 years Bo received ongoing psychiatric and mental health services from the community mental health center. His engagement in treatment waxed and waned, as did his symptoms. He had several six- to eight-month periods of remission and was hospitalized five additional times for severe manic or depressive episodes. Presently, Bo has been unemployed for 5 years and receiving Social Security Disability benefits for 3 years. After his most recent hospitalization, Bo was referred to the PACT team. His mother and brother continue to be supportive and are delighted to have the more intensive program to help Bo achieve stability again. In the PACT program, client services are reviewed every 120 days. Bo’s review is due, which is an opportunity to check his diagnosis for compliance with the new DSM-5 criteria.
Bo has stabilized somewhat since discharge from the hospital but continues to have attenuated manic symptoms. At the time of hospitalization, Bo’s symptoms were present most of the day, every day, so he exceeded the clarified requirement for diagnosis in the DSM-5. Among other symptoms, Bo demonstrated distractibility, but his grandiosity precluded him from acknowledging that. However, clinicians observed the distractibility in session; therefore, the criterion was met. Bo did not demonstrate mixed features or experience psychosis so those revisions in the DSM-5 are not pertinent here. He has received antidepressant treatment in the past but not in recent months; therefore, no extra consideration is necessary to ensure that criterion F is met. Given this presentation, Bo’s diagnosis remained bipolar I disorder, most recent episode manic.
Because of the improvement Bo has achieved since hospital discharge, in partial remission can be added to the diagnosis at his 120-day review. Therefore, his complete diagnosis is 296.45 bipolar I disorder, most recent episode manic, in partial remission. Bo’s improvement is tenuous, however, and requires ongoing medication compliance and supportive counseling. The PACT team is designed to provide this long-term support and counselors are an essential part of that program (Salyers & Tsemberis, 2007). Given the complexity and variability of Bo’s symptoms, a counselor may find it helpful to administer regularly the Level 1 Cross-Cutting Symptom Measure to track changes over time. The counselor also could use the more specific Level 2 assessment to track symptoms in a particular domain such as mania.
Saul: Schizophrenia
Saul is a 20-year-old unemployed male. He currently lives in the home he grew up in with his mother, father and 14-year-old brother. Since graduating from high school, Saul has worked a part-time job while taking classes at a local community college.
Saul was first hospitalized at age 18 after he began to tell his family that he was a messenger from God. Saul’s family had a difficult time understanding what Saul was telling them, as it was uncharacteristic of him, but initially they were not concerned. However, Saul’s parents became more alarmed as they noticed he was increasingly more preoccupied with the belief. They also observed that his grades began to suffer and he was spending more time reading religious material online rather than socializing with his friends. After a couple of months of this and no signs of improvement, Saul’s parents contacted the local community mental health center for help.
Saul was voluntarily hospitalized because of uncharacteristic behavior. While in the hospital, he received a mental health evaluation from a psychiatrist. The psychiatrist noted that there was no evidence of disorganized speech, catatonia or negative symptoms. Additionally, Saul denied auditory and visual hallucinations and the psychiatrist did not observe Saul responding to internal stimuli. Saul reported that his mood was good and the psychiatrist noted no evidence of mania or depression. However, Saul routinely told the psychiatrist he was a messenger from God and often perseverated on the topic. He also reported the detrimental impact that his work as God’s messenger was having on his life. Saul and his family both denied any history of substance use, and a toxicology screen was negative for common street drugs, which could have led to the sudden change in behavior. In sum, there was no medical explanation for the change in behavior.
Using the DSM-IV-TR, the psychiatrist diagnosed Saul with 295.30 schizophrenia, paranoid type. He cited evidence of a bizarre delusion, thus requiring only one symptom to meet criterion A. The psychiatrist noted paranoid type, which was appropriate given Saul’s preoccupation with the religious themes and the grandiose nature of the delusions. The psychiatrist prescribed an antipsychotic medication for Saul and encouraged him to follow up with a counselor and psychiatrist in the community for outpatient care.
After discharge from the hospital, Saul received outpatient treatment from a licensed professional counselor and a psychiatrist. Saul took his medication each day with the assistance of his parents, who monitored his compliance. Saul was able to complete high school and started courses at a community college and worked part-time. However, when Saul was 20 years old, his psychiatrist noted a concern in his blood work, which was likely a side effect of the medication he was taking. Saul’s psychiatrist changed his medication because of this concern.
Quickly, Saul’s preoccupation with his role as a messenger from God returned. Saul again began to have difficulty with course work and dropped out of school. He was fired from his job because his boss became frustrated that Saul was frequently late, took too long to complete tasks at work and appeared disengaged. There also were reports that he was scaring customers by asking about their religious faith and commitment to God. When Saul stopped showering, his parents requested that he be evaluated again and he was hospitalized for a second time.
During his second hospitalization, Saul received another mental health evaluation from a psychiatrist. Saul continued to insist that he was a messenger from God and he perseverated on religious themes. Saul said he felt compelled to act on God’s commands, which he now heard as a deep male voice. The psychiatrist noted that Saul’s responses in session were delayed, he frequently asked for questions to be repeated and he seemed to be responding to his hallucinations. Using the DSM-5, the psychiatrist diagnosed Saul with 295.90 schizophrenia, multiple episodes, currently in acute episode. There was evidence of at least two symptoms for criterion A: evidence of delusions, auditory hallucinations and diminished emotional expression. Saul reported feeling sad or down at times, but through Saul’s report and the treatment team’s observations, it appeared that this occurred less than half the time during an active psychotic phase, which ruled out schizoaffective disorder.
Saul’s psychiatrist also completed a quantitative severity assessment using the Clinician-Rated Dimensions of Psychosis Symptom Severity from the DSM-5 (APA, 2013). Saul’s psychiatrist rated the impairment in the past seven days for the eight areas of functioning using a scale ranging from 0 (no presence) to 4 (present and severe). The psychiatrist rated hallucinations as 4 because Saul was frequently responding to voices, which limited his ability to track their conversation and impaired his functioning. Delusions were rated 3 because of pressure to follow God’s commands. This pressure caused Saul to isolate from others, research religious themes, neglect his personal hygiene and pester customers about their beliefs, which cost him his job. Disorganized speech was rated 0 as the psychiatrist noted Saul’s speech was normal. The psychiatrist did not observe any abnormal psychomotor behavior; therefore, it was scored 0 as well. Negative symptoms were rated 3 as Saul displayed moderate decrease in facial expressiveness. Impaired cognition was rated 3 as Saul was unable to take classes and concentrate at work. Thus his functioning was significantly below what would be expected from an individual of Saul’s age and socioeconomic status. Depression was rated as 1 because Saul reported feeling sad or down some of the time, but did not appear preoccupied with sadness. Mania was rated as 0 because there was no evidence of elevated or expansive mood.
The Clinician-Rated Dimensions of Psychosis Symptom Severity scale may be repeated at hospital discharge or during subsequent treatment in order to track Saul’s progress. Additionally, Saul’s counselor may find it useful to track his symptoms using the Level 1 Cross-Cutting Symptom Measure. While in the hospital, Saul endorsed sadness on some of the past seven days. If Saul were to respond to an item on the depression domain as mild or greater, the counselor could also use the Level 2 Cross-Cutting Symptom Measure for depression to gather additional information.
Saul’s case is unique in that his initial presentation 2 years ago would not have met full criteria for schizophrenia had it occurred after the DSM-5 was released. At the time of his second hospitalization, when the DSM-5 was in use, the additional symptoms made it clear that schizophrenia was the appropriate diagnosis for Saul. Ongoing treatment may help Saul achieve stability and improve his quality of life, and the repeated use of the severity scale may help track his progress.
Conclusion
These scenarios illustrate which changes from DSM-IV-TR to DSM-5 had an impact on preexisting client diagnoses. Note the core diagnoses did not change, only some of the terminology and specifiers. Why then is it important for counselors to learn about the changes and review existing client diagnoses? Consider the following reasons for careful diagnostic practice.
Section E.5 of the ACA Code of Ethics (ACA, 2014) mandates that counselors maintain careful, culturally sensitive diagnostic practices. Section A.2.b further requires counselors to take steps to explain the diagnosis and its implications to their clients. Some clients, particularly those who were previously diagnosed, may not have had the opportunity to discuss the meaning of their diagnosis or its implications with a mental health professional. They may have little knowledge at all or longstanding misconceptions. Some clients, like Martha, may have been first diagnosed by a primary care physician who was not familiar with the DSM and the specific features of depression that it details. The release of the DSM-5 is an opportunity to check in and use counseling and advocacy skills to help clients develop an accurate and healthy understanding of their diagnoses. The cross-cutting symptom measures provide a stimulus to engage in a dialogue about the client’s symptoms and treatment needs. Use of these instruments gathers valuable information and helps clients feel better understood (Clarke, 2013). Counselors can have a tremendous influence on how clients conceptualize their mental health, so taking advantage of this opportunity to shape it in a positive way is a great service to the client.
Additionally, converting to DSM-5 criteria and terminology is essential to meet the common language goal that inspired the initial creation of the DSM. Each edition of the DSM has included revisions that changed the criteria or titles used to describe disorders, but instant conversion to the new terms does not happen in practice. For example, manic-depressive disorder became bipolar I disorder in the third revision of the DSM almost 35 years ago (APA, 1980) and yet some people still use the antiquated term today. Attending to the changes and discussing them with colleagues and clients will speed adoption of the new common language. Modeling ethical, careful, current diagnostic practices may have a positive ripple effect on colleagues as well. If counselors, supervisors and counselor educators all use the terms and criteria set forth by DSM-5, we can more easily communicate within our profession and across treatment teams.
In fact, the DSM-5 authors made a special call for all clinicians to use the DSM-5 language as carefully and specifically as possible. For example, authors asked clinicians to avoid using the catchall diagnoses at the end of each section (i.e., not otherwise specified in the DSM-IV-TR, other specified and unspecified in the DSM-5; Phillips, 2013). These diagnoses are sometimes necessary in the short term (as in the case of Bo above), but with additional information a more defined diagnosis is often possible. The DSM-5 authors also called on clinicians to attend carefully to the use of specifiers (e.g., Coryell, 2013; Goldberg, 2013). Many of the revisions to specifiers were made because of the potential impact on client treatment. For example, the presence of anxious distress (as in Martha above) complicates the treatment of depression. Noting the anxious distress in the diagnosis itself brings attention to those symptoms and reduces the likelihood that they will be overlooked. For Martha, it seems that when she is able to rise up out of her depression enough to engage in life, her anxiety surges and discourages her from attempting engagement again. It may be that her anxiety needs to be addressed before she can effectively work on her depression.
The DSM-5 authors also cautioned clinicians that one of the limitations of the DSM-IV-TR was that too many diagnostic criteria overlapped, leading to what is called “artificial co-morbidity” (Tandon, 2013). Individuals may be diagnosed with multiple disorders because of shared criteria. For example, a client’s irritability, social withdrawal and anger outbursts may have underlying depression, mania, delusional thinking or anxiety. These are features of bipolar disorder, major depressive disorder, schizoaffective disorder and post-traumatic stress disorder, and the convolution can lead to overdiagnosis and, ultimately, improper treatment. Arriving at more accurate diagnoses quickly will lead to better care for clients, and DSM-5 includes a new tool to help counselors do just that. The Cross-Cutting Symptoms Measures allow a counselor to assess for the presence of symptoms that are related to multiple diagnoses and consider whether a specifier or comorbid diagnosis is appropriate (APA, 2013).
Accurate diagnoses also are essential to ongoing research on these and other mental health conditions. Medical record research is increasingly common, particularly with the adoption of electronic medical records and the conglomeration of large managed care companies. That means that the diagnoses counselors record on billing documentation or enter into client medical records are likely to become part of a behind-the-scenes research project. Often these projects use data points such as diagnosis, number of hospitalizations, frequency of outpatient sessions and medication dosages to conduct large-scale analyses of trends or outcomes in treatment. Research like this does not require client or clinician consent because the existing data is anonymized and permission is granted en masse by the organization. Important evidence-based practice recommendations come from this type of study; therefore, using the most accurate documentation, whether the counselor intends to participate in research or not, is important for valid studies.
In sum, the DSM-5 has set forth changes in criteria and terminology used to describe major depressive disorder, bipolar I disorder and schizophrenia. Counselors can take advantage of this opportunity to help clients develop a healthy, accurate understanding of their diagnoses. The release of the DSM-5 also is an opportunity to revise diagnoses, paying careful attention to specifiers, in order to adhere to the common language it establishes. Thorough, accurate diagnoses support the selection of effective treatments and ongoing research on the treatment of these conditions. All counselors, supervisors and counselor educators can work together as we address these important goals.
