The Alcohol Safety Action Program (ASAP), in accordance with its goals and directives, determined, in 1980, the need for an evaluation of its services. In response to that need, the present study was conducted between April and October, 1980. The initial step in this evaluation is a review of the relevant literature. The review includes literature in the areas of: treatment evaluation methodology, follow-up studies of alcohol treatment, and management of drunken drivers. In addition, the history and current organization of the Portland ASAP are discussed. The study employs a one group pretest-posttest design and utilizes the Oregon Quality of Life Questionnaire. A comprehensive description of study methodology is followed by discussion of study findings and implications for practice. Finally, with the intent of providing direction for future study, the methodology of the present study is critiqued.
