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.
