Peer education is an important part of health education programs. In smoking prevention programs, peer leaders are particularly efficacious. Yet, research on peer leaders' perceptions of these programs is minimal. This study assessed the perceptions of elected peer leaders (N = 207) in one seventh grade smoking prevention program and one chemical abuse prevention program in spring 1984. Peer leaders' assessments of the adequacy of their training, the programs' components, the programs' influence on their behavior and attitudes, and the efficacy of the programs were analyzed. Differences between genders and the level of peer leader enthusiasm also were assessed. Further research with peer leaders is suggested as a way to strengthen ongoing health promotion efforts.
