Abstract
A two-part study expanded current information on research participation where predictors of research participation: a) age and race, b) surface barriers, c) developmental factors, and d) deep barriers, were examined. Sixty-two African Americans and 37 White American adults responded to eight self-report measures. Time availability emerged as the best single predictor of participation. In addition, African Americans and White Americans differed primarily on developmental factors (i.e., mistrust, racial socialization, and ethnic identity development). Path analysis revealed that race and age were indirectly related to participation via developmental factors or deep barriers. The data suggest that researchers attempting to recruit and retain participants (regardless of race) should consider: time management, creating an environment of trust, and provide benefits for participating. Although this study provided information on recruitment and possibly retention, social scientists must continue research in this area, so that accurate knowledge about research participation can be obtained.
