The project has introduced a new method of domestic violence prevention in the Czech Republic called controlling aggression or anger (anger management). The methodology of the Norwegian organisation Reform has been adapted to Czech conditions and was successfully tested in a therapeutic group for men who have committed violence against people close to them. This has helped improve services in the field of domestic violence prevention in terms of working with offenders. We achieved all project goals: by extending our capacity to work directly with offenders, we have helped reduce the overall occurrence of domestic violence in the Czech Republic. The project had a direct impact on 13 intensely trained experts, 85 workshop and seminar participants, 12 therapeutic groups, and 22 perpetrators of violence who were given counselling. It also impacted thousands of members of the general public through the media, the Internet, social media, and 3,000 leaflets. The project results are also sustainable –the anger management methodology has been adapted for the Czech environment and the first Czech experts have been trained in it. Recipients (domestic violence perpetrators, experts, and the public) were directly involved during all project activities. The organisation Reform was actively engaged throughout the project as a consultant and instructor, and shared their know-how and provided consultation.
