A study described youth programs sponsored by 17 major national adult service organizations, including the traditionally male groups, mainline women's groups, and minority service organizations. Specific focus was on developmentally appropriate, community-based services for at-risk adolescents, aged 10 to 15. Information was collected through in-depth telephone interviews. Surveys were supplemented by examining annual reports, program newsletters, and training materials. Findings indicated that adult service clubs performed a variety of sometimes conflicting and contradictory functions. They could be categorized according to the degree to which affiliates are autonomous and the degree to which there is a hierarchy and a system of formal communication between the national office and local clubs. Adult service clubs did not conceive of early adolescence as a specific age category; programs were not generally targeted to at-risk, young adolescents. Recommendations to strengthen activities in this area included the following: promotion of awareness of at-risk, early adolescents; program development and cross-fertilization; evaluation; eradication of the vestiges of exclusivity; and further study. (Profiles of the 17 organizations are provided. Each profile touches on the following areas: volunteers, nature of program development, and youth programs--national programs, local programs, public policy, collaborations, and publications. The interview questionnaire and 13-item bibliography is appended.) (YLB)
