Over the past 40 years, theatre has reemerged in the church as a tool for entertainment-education (EE). This study explores the persuasiveness of theatre as an EE tool using Milton Rokeach's belief system theory: If a message increases audience self-awareness of values, it can decrease satisfaction with self, and increase desire to change behaviors to match values. In addition, the performance theories of Brook, Turner, and Schechner were utilized–namely that live theatre creates a unique existential experience that can transform social dramas. In 2007, this study used surveys and interviews to explore an audience's self-awareness, self-satisfaction, behavioral intentions, awareness of media influence, and behavior change in response to live theatre on the subject of body image. The audience was composed of students at three Christian colleges. The audience was sampled (T₀) immediately before, (T ₁) immediately after, and (T₂) two months after the performance and compared to a control group. ANOVA and paired samples t-tests reveal a significant increase in self-awareness and desire to change behavior between T₁ and T₂. However, there was no significant change in self-satisfaction or awareness of media influence. Positive changes in body image, eating, and exercise behavior were reported by audience members and attributed to the performance. Increases in self-awareness and desire to change behavior reinforce Rokeach's theory of behavior change, but lack of change in self-satisfaction requires further research. Positive behavior changes indicate the effectiveness of live theatre as an EE event and gives credence to the performance theories of Brook, Turner, and Schechner.
