The role of community health advisors in community-based participatory research.

Mistrust and fear of research often exist in minority communities because of assumptions, preconceived ideas, and historical abuse and racism that continue to influence research participation. The research establishment is full of well-meaning 'outsider' investigators who recognize discrimination, health disparities, and insufficient health care providers in minority communities, but struggle in breaking through this history of mistrust. This article provides ethical insights from one such 'insider-outsider', community-based participatory research project implemented via community health advisors in the Mississippi Delta. Both community-based participatory research and community health advisors provide opportunities to address the ethical issues of trust, non-maleficence, and justice in minority communities. Implications for ethics-driven nursing research are discussed.
