Abstract
The records of 185 inmates rated on the Psychopathy Checklist-Revised (PCL-R) as part of a forensic evaluation for the US federal courts were reviewed for evidence of subsequent disciplinary reports in a 2-year follow-up. The Personality Assessment Inventory (PAI) was also administered to 149 of these inmates. The PCL-R Factor 2 score added significant predictive variance at the second step of a logistic regression analysis of disciplinary report outcome after demographics (age, education, ethnic status) and scores on the PAI Aggression Scale had been entered at step 1. The PAI Aggression Scale also displayed incremental validity by successfully predicting the presence of a subsequent disciplinary report at step 2 of a logistic regression analysis after age, education, ethnic status, and the PCL-R Factor 2 score had been entered at step 1. These and other results suggest that self-report measures may be just as effective as non-self-report rating scales in predicting forensic and correctional outcomes.
