Which battering interventions work? An updated Meta-analytic review of intimate partner violence treatment outcome research

This meta-analytic review is an update to the first meta-analysis of battering interventions (Babcock et al., 2004) and includes 59 studies that evaluated treatment efficacy for domestically violent men and women. The outcome literature of controlled quasi-experimental and experimental studies was reviewed to test the relative impact of Duluth, cognitive-behavioral therapy (CBT), and novel types of treatment on subsequent recidivism of violence. The first model examines studies comparing interventions to no treatment control conditions. The second model compares novel interventions to treatment as usual (i.e., the Duluth curriculum). Study design and type of treatment were tested as moderators in both models. Consistent with previous meta-analyses, effect sizes were in the small range, smaller in true experiments as compared to quasi-experimental designs when recidivism was based on partner or police reports. However, new experiments comparing novel treatments to the Duluth curriculum reveal effect sizes comparable to when comparing novel interventions to an untreated comparison group. Novel interventions, including Acceptance and Commitment Therapy and Circles of Peace had the largest effect sizes when put head-to-head with Duluth control groups. Future research directions include testing moderators and mechanisms of change of the battering interventions that work. Implications for evidence-based practice in criminal justice include broader implementation and continued testing of these novel interventions with demonstrated efficacy in stopping intimate partner violence.
