Exploring theoretical mechanisms of community-engaged research: a multilevel cross-sectional national study of structural and relational practices in community-academic partnerships.

The CBPR Conceptual Model identifies key theoretical mechanisms for explaining health equity and health outcomes in community-academic partnerships. The scholarly literature's preoccupation with synergy and relationships overlooks two promising practices-Structural Governance and Collective Empowerment-that interact from contexts through mechanisms to influence outcomes. These results also expand expectations beyond a "one size fits all" for reliably producing positive outcomes.
