ABSTRACT Leading a successful coalition that benefits both the members and the community is a difficult task. Coalitions are complex and require a great deal of skill to initiate, lead, and evaluate. This article examines a successful coalition, developed to build community capacity to address fetal alcohol spectrum disorder (FASD). FASD is a complex, multidimensional health issue common in many communities. Coalitions can be effective in tackling these types of issues and fit with community capacity-building approaches to health promotion. The Internal Coalition Outcome Hierarchy (ICOH) model (Cramer, Atwood, & Stoner, 2006a, 2006b) is used to retrospectively examine the internal constructs of the FASD Action Network and provide useful lessons learned for other coalition leaders and public health nurses. This hierarchical model demonstrates that sound internal processes lead to more successful outcomes and ultimately an increased impact on community issues. The usefulness of ICOH as a tool in evaluating the FASD Action Network and its application to other health-promotion situations with community capacity goals is described in this article.
