Behavioral correlates of selected MMPI-2 clinical, content, and restructured clinical scales

In this study, we evaluated the validity of the Restructured Clinical (RC; Tellegen et al., 2003) scales by identifying and comparing behavioral correlates of selected RC scales (RCd, RC2, RC4), their original Clinical scale counterparts (Scale 2, Scale 4), and conceptually related Content scales (DEP, ASP, CYN) in an outpatient clinical sample (N = 150). The results of this study indicate that RC4 is a stronger predictor of several antisocial behaviors than Clinical Scale 4 or the Content Scales ASP and CYN. In contrast, RC2 demonstrated significantly lower correlations with several behaviors conceptually related to depression than its Clinical scale counterpart or DEP. DEP was highly correlated with RCd (r = .91, p < .0001), suggesting that the 2 scales may be measuring similar constructs. Overall, the results of this study demonstrate relatively few differences among the scales selected in their ability to predict extratest behaviors.
