Exploring the link between personality disorder and criminality in a community sample

This study sought to identify, among a sample of 224 community residents with DSM-diagnosed personality disorder (PD), those personality and criminal history features associated with a combination of antisocial and borderline PDs (APD/BPD). After identifying first- and higher-order factors through factor analysis of IPDE item scores, forensic history and personality correlates of the identified higher-order factors were identified using regression analysis. Those having APD/BPD were more likely than the remainder to have received a conviction for violence and a custodial sentence. They showed higher trait anger and impulsivity and a greater history of aggression, and scored significantly higher on a higher-order "psychopathy" factor. In contrast, anankastic traits were inversely related to criminal history variables. It is concluded that APD/BPD represents a particularly criminogenic blend of traits likely to be overrepresented in high-secure forensic samples, and underrepresented in community PD samples. Future research should address the mechanisms through which PDs are related to criminality.
