Predictive Validity of the MMPI–2 Restructured Clinical (RC) Scales in a Batterers' Intervention Program

Abstract

We examined the convergent and discriminant validity of the MMPI–2 Restructured Clinical (RC) scales in predicting relevant historical variables, treatment success, and recidivism in offenders enrolled in a batterers' intervention program. We used a sample studied previously by Petroskey, Ben-Porath, and Erez (2002) Ben-Porath, Y. S. . The role of demoralization variance in self-report measures of personality and psychopathology. Poster presented at the 2005 Annual Conference for the American Psychological Society. Los Angeles, CA. May, [Google Scholar], which included an ethnically diverse group of 483 men enrolled in a psychoeducational batterer's intervention program. We coded various historical variables (e.g., criminal history, substance abuse problems, mental health treatment, anger problems, and amount of partner violence), treatment dismissal, and recidivism up to 1 year posttreatment. Correlational analyses with the historical variables provided evidence of convergent and discriminant validity of the RC scales in this forensic sample. Regression analyses showed that these scales added to the historical variables in predicting treatment failure and recidivism. Relative risk analyses indicated the extent to which individuals entering treatment with elevated scores on RC4 and RC9 were at increased risk for these negative outcomes.
