This chapter discusses adolescent drug abuse relapse prevention. It presents the following four conclusions regarding the efficacy of prevention programs. First, more controlled studies are needed to evaluate the long-term effectiveness of relapse prevention strategies with adolescents in reducing factors such as cravings and increasing their ability for self-assessment, monitoring, self-control, and maintenance of abstinence behaviors. Secondly, studies are also needed to examine posttreatment predictors of relapse. In order to accomplish this, well-designed comparison groups must be utilized in studying the effectiveness of relapse prevention strategies. Thirdly, some degree of consensus regarding standard definitions would enhance the comparability of studies. Finally, although there is a heightened awareness of the importance of relapse prevention, there is substantial lack of coordinated attempts to deal with the problem of relapse among adolescents. Overall success of prevention programs will ultimately depend on a well-orchestrated coordination among families, schools, communities, treatment centers, support groups, and social institutions. Also included is a facilitator's manual which is a practical guide for teaching content through guided experiential projects. Six objectives and six student exercises are provided.
