The Professional Counselor /Volume 5, Issue 4 520 Phase 3. Second confirmatory factor analysis. A second CFA was conducted for cross-validation. This second CFA was conducted on the 13 items from the instrument survey to assess a three-factor measurement model that was based on the results yielded through the first confirmatory factor analysis. The same computer program and estimation tactics were used to conduct the second CFA. Results Phase 1. Exploratory Factor Analysis Complete descriptive statistics for the responses to each of the 13 items are presented in Table 1. The response categories for all questions are dichotomous and also identified in Table 1 as “On Target” or “Struggling,” while incomplete data are labeled “Missing.” A total of 1,158 surveys were analyzed through the EFA. The decision to retain factors was initially guided by visually inspecting the scree plot and eigenvalues. The EFA resulted in two factors with eigenvalues greater than one (one-factor = 8.055, two-factor = 1.666, and three-factor = 0.869). In addition, the scree test also supported the idea that two factors were retained because two factors were left of the point where the scree plot approached asymptote. However, considering goodness-of-fit indices, the models specifying a three-factor structure and four-factor structure fit the data well. Methodologists have suggested that “underfactoring” is more problematic than “overfactoring” (Wood, Tataryn, & Gorsuch, 1996). Thus, there was a need to arrive at a factor solution that balanced plausibility and parsimony (Fabrigar, Wegener, MacCallum, & Strahan, 1999). Figure 1 .
