One of the most important clinical constructs related to the criminal justice system is psychopathic personality, which is associated with a number of potentially dangerous outcomes in correctional and community settings. Few researchers have examined the convergent validity between self-report and clinician-administered instruments assessing psychopathic personality. The current study assessed the convergent validity of psychopathic personality utilizing the Psychopathy Checklist-Revised, Second Edition (PCL-R; Hare, 2003), the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld & Widows, 2005), and the Antisocial Features scale of the Personality Assessment Inventory (PAI-ANT; Morey, 1991) simultaneously for the first time with a correctional population. Correlation matrices, moderator analyses, paired t-tests, and multiple linear regression analyses were utilized to examine potential sex differences and convergent validity of the PCL-R, PPI-R, and PAI-ANT with 139 male and 146 female first-time incarcerated inmates in the state of Oregon. Results indicate significant differences between males’ and females’ total scores of psychopathy on the PPI-R alone. When examined as a group, each measure demonstrated at least moderate positive relationships between each measure. When separated by sex differences, relationships were observed between all measures except male PCL-R and PAI-ANT scores. Female participants’ total scores demonstrated significant relationships on all measures, and significant differences among correlations between PCL-R and PAI-ANT, and PPI-R and PAI-ANT. Multiple linear regression analyses indicated that the PPI-R predicted PCL-R scores for the males and females as a group. However, when separated by sex, the PPI-R predicted male PCL-R scores, and the PPI-R combined with PAI-ANT significantly predicted female PCL-R scores. Overall, this sample of female inmates demonstrated stronger convergent validity on all measures and stronger predictive power on PCL-R scores than the male inmates. These findings add valuable information towards understanding the validity of these three assessment tools examining psychopathy in male and female inmates.
