Objective: Intimate partner violence (IPV) perpetrators with alcohol and/or other drug use problems (ADUPs) have been identified as one of the main high-risk and highly resistant groups of perpetrators requiring special attention in intervention programs for IPV perpetrators. This randomized controlled trial (RCT) aimed to evaluate whether an individualized motivational plan adjusted to ADUPs (IMP-ADUPs) was superior to standard motivational strategies (IMP) in reducing ADUPs, and IPV and increasing treatment adherence in IPV perpetrators. Method: Data from a full sample of IPV perpetrators (n = 140) and a subsample of participants with ADUPs (n = 55) were collected at pre- and post-intervention and 12-month follow-up. Final outcomes included alcohol, cocaine, and cannabis use, self-reported IPV, risk of recidivism assessed by facilitators, and official IPV recidivism. Proximal outcomes included treatment adherence (stage of change, intervention dose, active participation, and dropout). Results: Both intent-to-treat (ITT) and per-protocol (PP) analyses were conducted. The IMP-ADUPs condition was superior to the IMP in reducing alcohol use at post-intervention in both the full sample and ADUPs subsample. The full sample of participants in the IMP-ADUPs condition were in a more advanced stage of change post-intervention and showed increased active participation during the intervention process than IMP participants. All participants were in a more advanced stage of change at post-intervention and reduced their alcohol use and their risk of recidivism at post-intervention and 12-month follow-up. Conclusions: These results underscore the need to develop individualized treatment approaches to address participants’ risks and needs and promote their motivation to change.
