A program for improving adolescents' decision-making skills to reduce the number of inappropriate behavioral choices related to wellness is described. The targeted population consisted of seventh and tenth grade students in a rural, middle class community. Data from local law enforcement records and school-based program referrals supported interpretation of the problem as inadequate decision-making skills. Analysis of probable-cause data revealed that peer and societal pressures as well as developmental issues contribute to inappropriate decision making among adolescents. Review of curricula content and instructional strategies revealed a lack of emphasis on skill development and an overemphasis on delivering information. Analysis of the problem setting, combined with solution strategies suggested by knowledgeable others, resulted in the following interventions: formal instruction in decision-making skills and infusion of the decision-making model into other health-related curricula. Postintervention data indicated an increase in knowledge of health facts, improvement in social skills within the classroom environment, and an increase in the ability to apply a decision-making model to teacher-constructed situations. Appendixes include student tests, supporting data, and program materials. (Contains 52 references.) (EMK)
