Theater has been used as an educational tool since the Great Depression era, and it is currently considered an effective tool for health promotion and reducing risk-taking behaviors among youth. Theater projects are well suited for communicating prevention messages to youth audiences because they can depict real-life settings and characters who can change during the performance in different ways as the story unfolds. Although theater-as-education may be effective for addressing a wide range of health and risk behaviors, previous programs that have used this strategy have experienced limitations. First, many programs fail to use a theoretical foundation, thereby ignoring principles that can be transferred to teaching and practice settings. Second, theater-as-education projects often lack systematic assessment of their impacts on audience attitudes, beliefs, and behaviors, so the effects of these programs are not well documented. Last, many theater-delivered programs fail to employ a community-based process, which limits their contextual validity. This article describes the development and assessment of the theater-as-education component of a prevention marketing campaign that addresses attitudes toward tobacco and alcohol use, the demonstration of refusal skills, and the clarification of norms regarding use of these products among young adolescents. This program addresses above limitations, and it provides a replicable model for developing a theater-as-education production for schools and communities to follow. (Contains 3 figures.)
