Community-based participatory research methodology is driven by community interests and rooted in community involvement throughout the research process. This article describes the use of community-based participatory research methodology in the HEAAL project (Health and Mental Health Education and Awareness for Africans in Lowell), a research collaboration between Christ Jubilee International Ministries-a nondenominational Christian church in Lowell, Massachusetts, that serves an African immigrant and refugee congregation-and the Massachusetts General Hospital Department of Psychiatry. The objective of the HEAAL project was to better understand the nature, characteristics, scope, and magnitude of health and mental health issues in this faith community. The experience of using community-based participatory research in the HEAAL project has implications for research practice and policy as it ensured that research questions were relevant and meaningful to the community; facilitated successful recruitment and navigation through challenges; and can expedite the translation of data to practice and improved care.
