Toward a social ecology of community coalitions.

This article is guided by several premises. First, community coalitions fit with a social ecology perspective of health promotion because they work with multiple domains and promote community change. Second, the community context affects the functioning of coalitions. Third, key leaders are an important part of the social fabric of a community and influence the social ecology of a community; therefore a coalition should include key leaders and influence them and their organizations. The purpose of this article is to advance an understanding of the social ecology of coalitions by describing concepts, variables and results from two national studies and by providing anecdotal evidence and a measure of key leaders from our own work. After briefly defining and describing community coalitions, we: (1) review literature on contextual variables and community coalitions, (2) provide examples of contextual variables influencing community coalition development, and (3) discuss the relationship of key leaders in multiple domains and community coalitions. The article concludes with a discussion of the need for a framework of contextual variables and a promising next step.
