"Data Trends" reports present summaries of research on mental health services for children and adolescents and their families. The article summarized in this "Data Trends" presents a model of effectiveness for wraparound teams, derived from a review of research and theory on effective teams. Using this framework, the authors discuss some of the challenges experienced by wraparound teams, make specific recommendations for strategies to improve team effectiveness, and suggest hypotheses for future research. In the article, the authors note additional research is required to test the hypothesized relationships among dimensions of team functioning. They conclude that nevertheless, wraparound teams can benefit from the lessons identified in their synthesis of the extensive research on effective teams. (Contains 1 figure.)
