Determinants of community coalition ability to support evidence-based programs.

This study examines how aspects of coalition functioning predict a coalition's ability to promote high-quality implementation of evidence-based programs (EBPs). The study involved 62 Communities That Care (CTC) coalitions in Pennsylvania measured annually from 2003 to 2007. Findings indicate that the communities with higher levels of poverty and longer existing coalitions are related to lower support for high-quality EBP implementation. Several aspects of coalition functioning-including higher levels of funding; leadership strength; board efficiency; strong internal and external relationships; and fidelity to the CTC model-significantly predicted support for high-quality EBP implementation. Earlier measurements of coalition functioning (2003-2004 and 2005-2006) predicted EBP implementation (2007) more strongly than concurrent coalition assessments (2007). The discussion focuses on how coalitions and technical assistance providers can improve coalition support for the implementation of EBPs.
