This article examines the role that social network theory and social network analysis has played in assessing and developing effective primary prevention networks across a southeastern state. In 2004 the state began an effort to develop a strategic plan for the primary prevention of violence working with local communities across the state. The process included an analysis of how family service organizations and community collaborators networked to solve community problems. In 2005, the state joined the Center for Disease Control and Prevention's Enhancing and Making Programs Work to End Rape project to specifically focus on building capacity for primary prevention of perpetration of sexual violence.
