ABSTRACT Sexual violence is a major public health and social problem in the United States and worldwide. Unfortunately, little is known about the effectiveness of sexual assault preventive interventions (SAPIs) in deterring future sexual violence. To bring forth more systematic and well- informed studies, it is essential for researchers to know which SAPIs have been evaluated and the results of these evaluations. In response to this need, RTI International performed an evidence- based review of SAPIs, documented what is known about SAPI evaluation research, identified significant gaps, and provided recommendations for future sexual assault prevention practice and research. This systematic, comprehensive literature review of English-language articles (within and outside the United States) evaluating SAPIs generated study-specific descriptions as well as summary information on a variety of study characteristics. In conducting this review, RTI followed the rigorous methodology developed by three organizations recognized internationally for facilitating
