Community-based participatory research (CBPR) is an approach to research that recognizes the specific knowledge and abilities that individuals from diverse backgrounds bring to the generation of new knowledge for the purpose of social action aimed at improving public health and health equity. In this article, the authors apply Gaventa and Cornwall's dimensions of participatory research to the analysis of 12 semistructured interviews with members of our Community Advisory Committee for the Participatory Research in Ottawa: Understanding Drugs (PROUD) study. This process-to-outcomes framework may help projects more systematically explore their experiences in relation to common CBPR principles and lead to greater conceptual clarity.
