We have presented an example of how the CBPR approach can be applied to PBRN research. Consistent with current concepts about CBPR, community representatives participated directly in defining research priorities, in refining the study protocol, in informing data collection and analysis, and in scientific dissemination. Research findings have been returned to the community. Several other facets of CBPR−as defined by Wells−were employed during the project, including regular communication, project transparency, financial compensation, respect for values, accountability, and community and patient evaluation of progress.7
