Evidence-based methods for assisting communities in successfully implementing practices are lacking in the field of implementation science. To fill this gap, the Community Development Teams (CDT) was developed to assist counties in developing peer networks focused on problem-solving and resource sharing to enhance their possibility of successful implementation. The CDT is an interactive, solution-focused approach that incorporates elements of the Interactive Systems Framework (ISF) for Dissemination and Implementation, An ongoing randomized implementation trial of Multidimensional Treatment Foster Care (MTFC) was designed to test the hypothesis that such interactive implementation methods are more successful at helping counties achieve successful and sustainable MTFC programs than standard individualized implementation methods. Using the Stages of Implementation measure, developed for this study, the potential benefit of these interactive methods is examined at different stages of the implementation process ranging from initial engagement to program competency.
