Few studies have examined characteristics and correlates of females who display assaultive behaviours towards their intimate partners. Personality disorders, anger responses, type of violence perpetrated, and post-traumatic stress reactions in female perpetrated intimate violence are important factors in diagnosis, management, and treatment considerations. The present study examined the incidence of cluster B per- sonality disorder traits in a non-clinical sample of self-identified females who perpetrate intimate partner violence (IPV). Results suggest differences in anger responses, nature and severity of violence perpetrated, and post-traumatic stress reactions across personality disorder categories. The numerous important ap- plied implications and future research directions are discussed.
