Communicating Effectively About Clinical Trials With African American Communities: A Comparison of African American and White Information Sources and Needs

Clinical trial (CT) participation is low among African Americans (AAs). To better communicate with AAs about the importance of CTs, the purpose of this study was to explore the communication sources and perceived effective communication channels and strategies through which the general public, AAs, and White individuals receive CT information. A quantitative telephone survey was conducted with AAs and Whites in one Southern state (N = 511). The measures assessed CT sources of information, perceived effectiveness of communication channels and strategies, CT understanding, and CT participation. Descriptive and bivariate analyses were used to compare responses overall and by race. AAs reported being exposed to more CT information than Whites. AAs received CT information most often through television, social media, and doctors compared to Whites. Perceived effectiveness of communication strategies and channels varied by race. AAs preferred simple and easy-to-understand CT information distributed through faithbased organizations. Whites preferred to receive CT information through a trustworthy source (e.g., doctor). There were no significant differences between AAs and Whites in their perceived effectiveness of media sources (e.g., Internet). Recommendations are provided to help health promotion practitioners and CT recruiters tailor information and communicate it effectively to potential AA and White CT participants.
