Evaluation of child abuse prevention programming is needed to determine if it is having the desired effects. While there are only a limited number of studies demonstrating the effectiveness of prevention programs, there has been research conducted at two levels, to study the direct effects of a specific program on the occurrence of child abuse and to measure the effect of the program on the factors contributing to the abuse. This quality control model focuses on critical performance areas of child abuse prevention programs including participant outcomes, defined as changes in affect, knowledge, behavior, status, and environment. Service events and efficiency are other aspects of a quality control system. 1 table, 2 figures, and 20 references (Author abstract modified)
