This document discusses psychopathy and the Psychopathy Checklist-Revised (PCL-R) used to assess psychopathy and predict recidivism. It outlines the interpersonal, affective, lifestyle, and antisocial features of psychopathy. The PCL-R measures psychopathy using two factors: interpersonal/affective traits (Factor 1) and impulsive/antisocial traits (Factor 2). Several studies cited found Factor 2 and overall PCL-R scores predicted recidivism, with psychopathic offenders reoffending more violently and frequently. The document recommends further research into causes and treatments for psychopathy and how aspects of Factor 2 contribute to its predictive ability regarding recidivism.
