Adoption of evidence-based programs for families by community agencies requires an understanding of variables that influence implementation. Managers and service providers from 64 community agencies reported on variables that affected the implementation of Triple P, an evidence-based parenting program. Both types of stakeholders reported adequate office resources; over half the managers and over two-thirds of service providers reported adequate training. Adequate office resources and positive agency characteristics, including organizational climate, were associated with higher program usage. Service providers' reports of the variables impacted their individual adherence rates; managers had broader perspectives of the quality of implementation in their organizations.
