Pastor support has been viewed as an integral part of successful faith-based health promotion programs; however, few studies have systematically studied these relationships. This study examined associations between pastor support and program-related variables among African American churches taking part in a physical activity and dietary intervention. Results showed that some pastor support-related variables were associated with participant recruitment, retention, and implementation of study requirements but not to changes in health behavior outcomes. Much work remains in how to conceptualize and measure pastor support. A better understanding of the pastor's role may assist in developing more effective faith-based programs.
