The Resource Centers for Minority Aging Research (RCMAR): community/researcher interaction and relationships.

For more than a decade, the National Institute on Aging (NIA) has led a program called the Resource Centers for Minority Aging Research (RCMAR). One of the four key components of the RCMARs is a Community Liaison Core whose objectives are to conduct research on recruiting community members for scientific studies and to facilitate working relationships with host communities. The articles in this supplement represent some of the scientific knowledge available on community-based participatory research (CBPR) at the RCMARs. The hope is that this supplement will motivate others involved in CBPR to more fully engage in the conduct of science related to relationships that mutually benefit communities and researchers.
