The utility of the Psychopathy Checklist-Revised (PCL-R) facet and item scores in predicting violent recidivism.

Abstract

There is relatively limited research on psychopathy in non-Caucasian ethnic groups and even less on the utility of the Psychopathy Checklist-Revised (PCL-R) that focuses on PCL-R facet and item scores in predicting violent recidivism. In this study, we assessed the utility of the PCL-R in prospectively predicting violent versus nonviolent recidivism during an 11-year follow-up window. A high-risk sample of 451 incarcerated Korean male offenders was assessed on the PCL-R at baseline. A total of 445 were reconvicted after release (353 violent and 92 nonviolent recidivists). Psychopathy facet scores were higher in violent compared to nonviolent recidivists. Facet 2 (affective) showed the strongest effect size (Cohen's d = 0.53; Percentage change in odds = 22.6%) in predicting violent recidivism. Analyses of the four items constituting the affective facet indicated that callous/lack of empathy (Percentage change in odds = 134.4%) and failure to accept responsibility (Percentage change in odds = 94.5%) were the strongest predictors of violent recidivism. Findings are to our knowledge the first to document the utility of the PCL-R in distinguishing violent from nonviolent recidivism and highlight the role of affective impairment (particularly lack of empathy) in violent recidivism.
