In this manuscript, the author draws from her experiences on a South Carolina educational-research obesity initiative to describe the important value that community psychology (CP) brings to medical education and healthcare organizations. The article describes the set of CP competencies that were most influential to the initiative and discuss how those competencies shaped the course of the initiative. More specifically, the author discusses: 1) how the use of a participatory action research approach helped ground project efforts in the practical realities of the participating practices, 2) how the team developed sociocultural and cross-cultural competence to better understand the complexity of weight-related issues in healthcare, and 3) how using an ecological perspective facilitated practice-wide improvements in obesity management. Through a series of examples, the article highlights specific ways medical education organizations can leverage community psychology competencies to move beyond traditional continuing medical education (CME) methods.
