Development and implementation of a collaborative, multistakeholder research and practice model on HIV prevention targeting Asian/Pacific Islander men in the United States who have sex with men.

We describe lessons learned from a national HIV prevention research program grounded in community-based participatory research, the Men of Asia Testing for HIV (MATH) Study, which targeted self-identified Asian/Pacific Islander men in the United States who have sex with men. We discuss the genesis of and impetus for the study and then describe its various facets, including accomplishments, challenges, and unanticipated consequences. We conclude with a discussion about the real-world practice of community-based participatory research with respect to the MATH Study in particular and similar research in general.
