The number of studies on the adverse effects of this diagnosis are scarce. Using vignettes in the present study, we have explored the relationship between the diagnosis personality disorder…

A large body of literature has shown a high prevalence of personality disorders in substance abusers. We compared a sample of substance abusers treated in a prison setting with substance abusers treated in a non-prison inpatient setting rated with the Millon Clinical Multiaxial Inventory-III.

Although research has consistently shown that men and women use intimate partner aggression (IPA) at approximately equal rates, there is little empirical research on whether the predictors of IPA are the same for men and women. The current study investigated whether borderline personality (BP) differentially predicted the use of IPA for men and…

In this study, five narcissism scales were compared in terms of alternative conceptualizations of narcissism offered by C. C. Morf and F. Rhodewalt (2001), D. L. Paulhus (2001), and S. Vazire and D. C. Funder (2006), using the…
