A State-Wide Effectiveness Trial of CTC in Pennsylvania

This chapter provides an example of how a community-based prevention system can be delivered at scale and with quality, using a state-wide dissemination of CTC in Pennsylvania as an example. As an early adopter of CTC, Pennsylvania began funding coalitions to implement CTC and EBIs in the mid-1990s. The chapter describes how the state formed successful partnerships between local community members, prevention scientists, and state-level agencies, including the creation of a state-level organization to oversee and help ensure successful implementation of CTC coalitions and EBIs. The chapter also summarizes the results of process and quasi-experimental outcome evaluations conducted in Pennsylvania. These evaluations have shown that CTC communities have successfully created and sustained broad-based, high-functioning coalitions, selected and sustained EBIs, and experienced reductions in youth behavioral health problems.
