This research focused on a new and unique therapy group for male batterers who were violent toward their intimate partners. The group is based on a small self-help group model, where a professional accompanies the group and serves as the facilitator of the process undergone by the group without interfering with the management of the group and its meetings. A total of seven group members were interviewed in a qualitative and phenomenological-interpretive research, which combined an outside observation by two authors with an inside observation by a professional who facilitated the group. The study focused on the method of empowerment of the group members, and it found three central themes: self-efficacy, group efficacy, and social efficacy. The research findings are explained from the new perspective of positive criminology.
