206 sampling adequacy was .88, indicating that factor analysis of these variables was appropriate. Barlett’s Test of Sphericity was significant, indicating that the items were excellent candidates for PCA. The factor loadings of each factor are presented in Table 1. Factor 1, perceived knowledge of McKinney-Vento, comprised seven items with factor loadings ranging from .83–.51 with 24.2% of the variance explained and a Cronbach’s alpha of .91. Items loading on this factor measured school counselors’ perceived knowledge of McKinney-Vento and the policies that schools must implement under McKinney-Vento. Factor 2, advocacy and provision of services, comprised seven items with factor loadings from .45–.81 with 21.19% of the variance explained and a Cronbach’s alpha of .81. Items on this factor described services and forms of advocacy that school counselors provided for students experiencing homelessness. Factor 3, perceived emotional and educational issues, comprised two items with loadings of .87 and .83 with 17.78% of variance explained and a Cronbach’s alpha of .96. Factor scores were created for each factor using the regression method approach so that participants had a score on each factor. The factor score is a linear combination of the items that load on that factor and is a standardized score. Therefore, the three factors used in the following regression analyses were standardized variables, each with a mean of zero and a standard deviation of one. Multiple Regression Analyses Following the PCA, we conducted three simultaneous multiple regression analyses with each factor serving as a dependent variable in each regression. The B coefficients and standard errors for each regression analysis appear in Table 2.
