Brief Summary

The current project aims to develop, implement and assess the effectiveness of an intervention program for perpetrators of intimate partner violence (both volunteers and court-mandated) that incorporates Motivational Interviewing techniques (MIT) as well as cognitive-behavioral and psychoeducational strategies implemented in a community setting. The intervention focuses on ending violence against the intimate partner and promoting the batterer's personal and social skills. The study uses pre- and post-treatment measures, with an experimental group (intervention) and two control groups (a group without intervention and a group without MIT). Data were collected at pre-test, post-test, and follow-up.
