Child sexual abuse continues to be an epidemic in the United States, with traditional, child-focused interventions thus far not proving successful at ameliorating this social problem. The purpose of this study was to conduct evaluation research on the STOP IT NOW! Program, a public health approach to intervention, to address the need for evidenced-based approaches and justification for the utilization of dwindling resources. Results from the mixed method design of a key informant survey administered to National Adolescent Perpetrator Network conference attendees and a multiple time-series comparison of child sexual abuse cases reported in a state receiving the traditional approach versus the public health approach suggested problems with widespread adaptation, a necessary stage for this approach to be successful. Further research is necessary to address obstacles to this stage and to examine initial promising results of the quantitative data gathered through the multiple time-series design.
