This paper describes the implementation and evaluation of a comprehensive program for teaching adolescents about alcohol use. A brief overview of research in the area of adolescent alcohol use is followed by a brief description and detailed outline of key facets of the Teams-Games-Tournaments (TGT) approach to alcohol education which is being tested throughout the State of Georgia; the approach is based on a behavioral group work perspective and encompasses peer support and group reward structures. Instruction in self-management techniques for students and instructor training are discussed. Pretest, posttest, and follow-up measures administered to students to assess knowledge of alcohol, drinking behaviors, attitudes about alcohol, self-esteem, and family relationships are described. Results are presented from a comparison of students (N=570) who participated in the TGT method with students (N=411) who received traditional instruction in alcohol education or no instruction; the findings suggest that the TGT procedure helped students gain knowledge about alcohol. Teacher and student evaluations of the TGT program are included and the significance of the TGT technique is discussed. (NRB)
