Developing an Integrated Violence Prevention for Men and Women in Treatment for Substance Use Disorders.

Rates of past-year partner and non-partner violence perpetration (VP) in substance use disorder (SUD) treatment samples exceed 50%, with studies showing rates of past-year VP exceeding 70% when considering violence occurring with either intimate partners or non-partners. However, SUD treatment programs typically do not include VP prevention interventions, and the few studies examining the impact of SUD interventions on VP have focused exclusively on partner VP. This study summarizes results of a randomized controlled pilot study of an Integrated Violence Prevention Treatment (IVPT) designed to address VP across partner and non-partner relationships as well as predictors of post-treatment VP. Participants were men (70%) and women (30%) in SUD treatment reporting past-year VP who were randomized to either IVPT or a control condition. The IVPT involved a Motivational Interviewing session targeting interpersonal conflicts, followed by five cognitive-behavioral therapy sessions focusing on VP prevention skills. The control condition included a session including a videotape and discussion of anger management, followed by five psycho-educational sessions common for SUD settings. Results showed that VP (total, partner, and non-partner) and cocaine use significantly decreased between baseline and 3-month follow-up for both conditions, and the IVPT group showed a significant decline in alcohol use. Analyses focusing on VP during follow-up revealed that baseline cocaine use and drinking during the follow-up predicted post-treatment VP. Together, these findings suggest that IVPT is a promising intervention (feasible, appears to impact drinking, an important factor related to violence) but that additional continuing care approaches may be indicated to sustain positive outcomes.
