Note: Total variance explained = 64.69; factor extraction method = unweighted least squares; rotation method = Varimax with Kaiser Normalization; Kaiser-Meyer-Olkin Sampling Adequacy = 0.80; Bartlett’s Test of Sphericity <0.001; Pearson correlations between factors as follows: negative/anxiety and functioning = −0.14, Negative/Anxiety and Positive = −0.016, and Functioning and Positive = −0.07. Factor loadings under .500 not shown to improve table readability. SOPS scale numbers are in parentheses.
