Abstract

Introduction: Despite the high prevalence of intimate partner violence (IPV) perpetration by men who use substances, limited evidence exists about how best to reduce IPV among this group. Method: A systematic narrative review with meta-analysis determined the effectiveness of interventions to reduce IPV by men who use substances. Inclusion criteria were randomized and nonrandomized controlled trials; adult heterosexual male IPV perpetrators where at least 60% of participants were alcohol and/or drug users; the intervention targeted IPV with or without targeting substance use (SU); outcomes included perpetrator and/or victim reports of IPV, SU, or both. Methodological quality was assessed. Results: Nine trials (n ¼ 1,014 men) were identified. Interventions were grouped into (1) integrated IPV and SU interventions (n ¼ 5), (2) IPV interventions with adjunct SU interventions (n ¼ 2), and (3) stand-alone IPV interventions (n ¼ 2). Cognitive behavioral and motivational interviewing therapies were the most common approaches. Data from individual trials showed a reduction in SU outcomes in the short term (3months; n ¼ 2 trials) and IPV perpetration at different time points (n ¼ 3 trials) for interventions compared with treatment as usual (TAU). Meta-analysis with integrated IPV and SU interventions showed no difference in SU (n ¼ 3 trials) or IPV outcomes (n ¼ 4 trials) versus SU TAU. Conclusions: Little evidence exists for effective interventions for male IPV perpetrators who use substances. Outcomes in integrated interventions were not superior to TAU in meta-analysis. Future trials should consider the nature of the relationship between IPV and SU in intervention design, duration of intervention, and type and timing of outcome measures.
