This study presents an evaluation of the implementation and short-term results of the Early Intervention Program in Situations of Child-Parent Violence. The information was obtained from two sources, the professionals responsible for developing the intervention and the participating parents and adolescents. The program was completed by 15 families and the data analysis was carried out with 37 participants. The intervention was effective. During the development of the program, physical and psychological aggression towards fathers and mothers decreased, the quality of parental relationships improved, and respectful behaviors progressively increased in all family members. The level of acceptance and satisfaction of the participants and the therapists regarding the program was favorable. These results contribute to the growing literature on the evaluation of the effectiveness of domestic violence programs and could be recommended for inclusion in family protection services.
