Observational study reveals problematic alcohol use intensifies personality-related intimate partner violence in couples, highlighting alcohol misuse as a vital intervention target.
Borderline and antisocial personality features relate to multiple externalizing behaviors, including intimate partner violence (IPV). However, not all individuals with borderline and antisocial traits perpetrate IPV. The strength of the personality-IPV link may be related to problematic substance use. We examined borderline and antisocial personality features, problematic substance use, and IPV in a community sample of couples. Positive relations between both borderline and antisocial features and IPV were stronger in conditions of high problematic alcohol use relative to low problematic alcohol use. Alcohol misuse may be an important factor to consider for IPV reduction in men with these personality features.
