Behavioral couples therapy for drug-abusing patients: effects on partner violence

Using data from a previous investigation, the purpose of the present study was to examine the effect of Behavioral Couples Therapy (BCT) on the prevalence of partner violence among married or cohabiting substance-abusing men (N = 80). Participants were randomly assigned to receive either BCT or individual-based treatment (IBT). The proportion of couples who engaged in male-to-female physical aggression was not different during the year before treatment for dyads in BCT (n = 17, 43%) and IBT (n = 19, 48%). However, a smaller proportion of couples in the BCT condition reported male-to-female physical aggression during the year after treatment (n = 7, 18%) than those in the IBT condition (n = 17, 43%). Dyadic adjustment, frequency of heavy drinking, and frequency of drug use during the year after treatment mediated the relationship between type of treatment and the prevalence of male-to-female physical aggression.
