Abstract

This study explored the validity of the PCL/PCL-R factor scores in predicting institutional adjustment and recidivism in forensic clients and prison inmates. Forty-two studies in which institutional adjustment, release outcome (recidivism), or both were assessed prospectively with the PCL/PCL-R yielded 50 effect size estimates between the PCL/PCL-R factor scores and measures of institutional adjustment/recidivism. A meta-analysis of these findings disclosed that Factor 2 (Antisocial/Unstable Lifestyle) correlated moderately well with institutional adjustment and recidivism, whereas Factor 1 (Affective/Interpersonal Traits) was less robustly associated with these outcomes. Direct comparisons of the mean effect sizes attained by Factors 1 and 2 revealed that Factor 2 was significantly more predictive of total outcomes, general recidivism, violent recidivism, and outcomes from the 12 most methodological sound studies than Factor 1. There was less differentiation between Factors 1 and 2 on measures of institutional adjustment.
