Alternatives, the Drug and Alcohol Prevention Program of Community School District 22 in Brooklyn, N.Y., is a broad-based substance abuse prevention program funded by the state that provides direct services to students and their families through three service modalities. These are prevention services, which provide students, parents, and the community with understandings of the nature and factors of substance abuse, primarily through prevention groups; intervention services, focusing on the needs of at-risk or using individuals either in small groups or individually; and the Alternate Class, which services students who do not function in the normal class setting. To evaluate the program's effectiveness, staff members, school district principals, parent associations, alternate class participants and their parents, and 345 students were surveyed during October 1981 and February 1982. Recommendations, based on survey results, included a more balanced male/female staff, intervention services for female students, and identifying the factors that relate specifically to the primary reasons for admission and measuring the change in these factors. (Descriptive and evaluation data are provided in separate sections and include a staff and student profile, review of service levels, and detailed survey results for each group surveyed. The appendix contains the Alternatives Program Student Profile form, the survey form for staff, principals, parent associations, students, and alternate class parents; the Alternative Questionnaire for group participation; and the Fordham University Survey and Piers-Harris Self Concept Questionnaire).
