Psychopathy has emerged as a useful construct with important implications for understanding criminal behavior and predicting recidivism. Though a structured clinical interview has been regarded as the method of choice for assessing psychopathy, assessment by self-report offers a number of practical advantages. The purpose of the present study was to further examine the usefulness of 3 psychopathy scales recently derived from the MMPI-2-RF by Sellbom et al. (2012). Developed to measure psychopathy as conceptualized in the Psychopathic Personality Inventory (Lilienfeld & Andrews, 1996), the MMPI-2-RF scales include Global Psychopathy (Py-T) and the facet scales of Impulsive-Antisociality (Py-IA) and Fearless-Dominance (Py-FD). The present study investigated the relationship of self-reported psychopathy to criminal history, substance abuse, and diversion program completion in a sample of community dwelling adult offenders. The sample consisted of 424 men and women enrolled in a court ordered, substance abuse Intervention In Lieu of Conviction (IILC) program. The participants in this archival study had a mean age of 33.50 years and 12.70 mean years of education. The sample included both men (52.5%) and women (47.5%), and more than 29% reported an ethnicity other than Caucasian. Most of the participants' offenses were substance related. As predicted, individuals who failed to complete their IILC programs had significantly higher Py-T scores than program completers. Hypotheses were supported regarding the association of psychopathy to a number of criminal history and background variables including juvenile offenses, juvenile history of placement in residential treatment, and previous arrests. As predicted, Py-T was also associated with severity of alcohol and illegal drug abuse. Regression analyses indicated that the Py-IA facet tended to predict the criminal history, background, and substance abuse variables more robustly than the Py-FD facet. An unexpected finding was that Py-T and both facet scales were inversely associated with severity of prescription pain medication abuse. Other results, clinical implications, limitations, and suggestions for future research are included. The present findings strongly supported the validity and usefulness of the MMPI-2-RF psychopathy scales.
