The monograph is based on the findings of task forces that included researchers, policymakers, and prevention/intervention specialists at the national, State, and local levels. The chapters target five specific audiences, including the priority target audience, youth from high-risk environments and their families; two subgroups, including black children and Hispanic and Latino youth; and two secondary audiences, namely parents and primary care physicians. The final chapter discusses how to work with intermediary groups to reach a target audience. This strategy is particularly useful in planning communications programs. Each chapter begins with a summary page and is divided into four sections: (1) understanding the audience; (2) knowledge, attitudes, and practices; (3) planning considerations; and (4) recommendations. 31 tables and 5 appendixes
