A randomized clinical trial of motivational enhancement therapy for alcohol problems in partner violent men

Abstract

This study examined the efficacy of brief alcohol intervention in the context of community-based treatment for partner violence. In a randomized clinical trial, 228 partner-violent men with hazardous or problem drinking were recruited at three Intimate Partner Violence (IPV) treatment agencies and randomly assigned to receive one of two 4-session alcohol interventions: Motivational Enhancement Therapy (MET: N = 110) or Alcohol Education (AE: N = 118). After completing alcohol intervention, participants received standard agency counseling services for IPV. Participants completed assessments of alcohol use, drug use, and IPV at pre-treatment, post-alcohol intervention, and quarterly follow-ups for 12 months. At the end of the 4-session alcohol intervention, MET participants displayed greater acknowledgment of problems with alcohol than AE participants (Partial ή² = 0.039, p = 0.006). Significant changes from baseline across treatment conditions (at p < 0.001) were observed for percent days of alcohol abstinence [95% empirical CI for Partial ή² =0.226, 0.296], heavy drinking [0.292, 0.349], illicit drug use [0.096, 0.156] and partner violence [0.282, 0.334]. No significant condition differences (treatment by time interactions) were found for alcohol abstinence [95% empirical CI for Partial ή² = 0.007, 0.036], heavy drinking [0.016, 0.055], illicit drug use [0.005, 0.035] or partner violence [0.001, 0.004]. Results encourage continued use of brief alcohol interventions in community IPV services, but do not provide evidence of a unique benefit of MET in reducing alcohol use in this population.
