The Safe and Healthy Communities Initiative is a comprehensive approach to sexual abuse prevention in 5 counties across Pennsylvania in a highly unique State/University partnership.  This initiative includes the coordination of evidence-based child sexual abuse prevention programs for adults in the community, school children, and at-risk parents. Programs will be delivered to 5% of the adult population (~71,000), 100% of second-graders (~17,000), and 100% of at-risk child welfare-involved parents. The aims are to empirically demonstrate that this coordinated effort (1) changes knowledge, attitudes, and behaviors of participants, (2) impacts rates of child sexual abuse, and (3) raises public awareness at the population level. The ultimate goal is to create a sustainable model of sexual abuse prevention that can be used at a systems level in PA and across the US.
