This paper provides a description of and rationale for components of a theoretically based conceptual model that guided the development and implementation of the Fathers and Sons Intervention Program. Using a community-based participatory research process, this intervention was designed to prevent risky health behaviors through strengthening father-son relationships among non-resident African-American fathers and their pre-adolescent sons. The implications of the conceptual model for future interventions with African-American fathers and sons are discussed. (Contains 2 tables and 1 figure.)
