The site-visit programs were selected to represent the range of juvenile drunk driving prevention programs operating in the United States and to provide diversity across the following variables: location, program intensity, message orientation/complexity, implementation scope, program focus, target population, and evaluation activities. Data collection solicited standardized information on each program while providing local informants with opportunities to inject background material, express personal opinions, and relate anecdotes pertinent to the program's operation. Research was designed to provide a variety of perspectives on each program. All interviews, however, involved persons close to the program or directly affected by it. The information provided for each program covers program description, site-visit activities, community and target population, assumptions and premises, implementation issues, and impact.
