Abstract

A follow-up of 107 male federal prison inmates previously tested with the Psychological Inventory of Criminal Thinking Styles (PICTS) and Psychopathy Checklist: Screening Version (PCL:SV) was conducted to test the incremental validity of both measures. The PICTS General Criminal Thinking (GCT) score was found to predict general recidivism and serious recidivism when age, prior charges, and the PCL:SV were controlled. The PCL:SV, on the other hand, failed to predict general and serious recidivism when age, prior charges, and the PICTS were controlled. These findings support the hypothesis that content-relevant self-report measures like the PICTS are capable of predicting crime-relevant outcomes above and beyond the contributions of basic demographic variables like age, criminal history, and such popular non-self-report rating procedures as the PCL:SV.
