To date, treatment interventions for domestic abuse perpetrators have been conducted almost exclusively in groups. However, the efficacy of such treatments relative to no treatment has not been thoroughly evaluated. Evidence suggests that individual treatments may be more effective than group treatments. This study will combine motivational enhancement therapy with cognitive and behavior change techniques to treat men who abuse their partners.

This study will be conducted in two phases. In Phase 1, an individual cognitive behavior therapy (ICBT) manual will be constructed. During Phase 2, participants will be randomly assigned to receive either 16 sessions of ICBT or 16 sessions of standard group therapy. Data on abusive behavior outcomes and secondary treatment targets will be collected from participants and their partners every 3 months for 1 year after the study.
