Research over the past 30years has demonstrated that excessive alcohol use meets all of the epidemiological criteria for causality. While neither a necessary nor a sufficient cause, excessive alcohol use does contribute to the occurrence of partner violence and that contribution is approximately equal to other contributing causes such as gender roles, anger and marital functioning. Current theories of how excessive drinking results in partner violence provide a potentially valuable framework with respect to who should be targeted for interventions with respect to alcohol-related partner violence and what those interventions should address.
