The ACT Against Violence Parents Raising Safe Kids program (ACT-PRSK) is an interactive violence prevention program developed by the American Psychological Association for parents of young children. The program teaches and supports parents in the areas of child development, roots and consequences of violence, anger management for adults and children, social problem solving, positive discipline, and the impact of media violence on children. Ninety-two parents/caregivers of young children participated in a study of the effects of the program on parenting behaviors. The first 50 participants were assigned to the intervention group and completed the ACT-PRSK program, and the remaining 42 parents/caregivers served as comparisons. Results indicated reduced spanking and reduced rate of hitting children with objects for the ACT-PRSK participants. Furthermore, the ACT-PRSK group evidenced improved knowledge, behaviors, and beliefs regarding violence prevention and parenting. Results provide support for the efficacy of this brief intervention for preventing child maltreatment. (Contains 4 tables.)
