An ad hoc steering committee will plan a 2-day open, interactive public workshop featuring presentations on research, practice, and policy surrounding implementation of evidence-based prevention od mental health and substance use disorders in community settings aimed at improving the well-being of children, adolescents and their families. An important component in addressing the mental and behavioral needs of children and families is implementation of evidence-based prevention, interventions, and policies in the community setting where children and their families live, work, and learn. The committee will identify specific topics to be covered at the workshop from current areas of interest including the selection of prevention interventions by communities, adaptation to local needs, methodological developments, and involvement of the community in the implementation research enterprise. The committee members will also select and invite speakers and other participants and moderate the discussions. A brief summary and a full-length summary of the workshop presentations and discussions will be prepared by a designated rapporteur in accordance with institutional guidelines.
