Abstract

Most of what we know about Psychopathic Personality Disorder (PPD) is based upon research with males. Considerably less research has examined female manifestations of the construct, however, some research suggests that Borderline Personality Disorder (BPD) may represent a female phenotypic expression of PPD, particularly among incarcerated offenders. The current study examined distinction and convergence between PPD and BPD. Utilizing a sample of 146 female correctional inmates as well as 109 female college students, the current study employed the Computerized Adaptive Test of Personality Disorder (CAT-PD) as well as other specific indices to explore the extent to which these two personality disorders overlap from a dimensional trait perspective, which the CAT-PD provides. Steiger’s T-tests were calculated to determine whether there was a difference in the magnitude of the correlations between CAT-PD traits and these two personality disorders. Hierarchical linear regression analysis were also conducted to determine whether additional traits could augment the prediction of these two personality disorders beyond the selected traits in the DSM-5 alternative trait model, located in Section III of the DSM-5. Implications of these results in light of explaining the overlap between BPD and PPD among females are explained.
