This study explores the communication experiences of two volunteer groups involved in the production of community theater musicals. Based on social exchange theory, it examined what group members perceived to be the positive benefits (primarily meeting people and having an opportunity to perform) and the negative costs (primarily disorganization, lack of coordination, and time issues) of participating in the groups. The study found that peer support and opportunity for social interaction, along with positive audience response, were the best predictors of positive reactions to their experiences and commitment to the show and community theater in general. These results provide insight into social exchange theory in group settings and can be applied to other community theater groups, as well as other volunteer organizations.
