This report evaluates this prevention program's effectiveness in producing social change in the area of alcohol abuse among Boys' Club participants. Concentrating on the program's third year, this paper presents summative evaluations for seven Boys' Club pilot sites. Each summation concentrates on the site's ability to translate models developed over the first two years of the program into prototypes for incorporation into the ongoing Boys' Club program and examines the impact the intervention effort had on participants exposed to the program. Specific activities undertaken at each site to develop and/or implement the program are described. Sample data from surveys and interviews conducted by evaluators to assess the project's impact on participants are presented. Patterns of drinking behavior among the project's participants and a control group are compared. The impact of the entire three year project on the Boys' Club of America is analyzed and recommendations made by evaluators regarding the project are outlined. (EB)
