Network analysis of a community-wide teenage pregnancy prevention initiative.

Although US teenage birth rates substantially decreased over the past two decades, it still remains the highest in the developed world. More innovative, community-wide initiatives are needed to combat the issue. In Oklahoma County, Oklahoma, the Central Oklahoma Teen Pregnancy Prevention Collaboration is utilizing the collective impact model to convene multiple organizations with the goal of making systems-level changes related to teenage pregnancy within the community. This study used an interorganizational network analysis to evaluate the current strength of relationships between organizations in the Collaboration. An interorganizational network survey assessed collaborative relationships (e.g. information sharing and joint planning) within the network. Using R software, network diagrams were developed to depict partner relationships, and network measures, including node-, group- and network-level measures, were calculated. The network depiction (n = 23) revealed that the network core was composed of organizations from multiple sectors, and the backbone organization served as the most central organization for most centrality measures. This study provides insight into how organizational relationships can be assessed in order to increase community capacity to address teenage pregnancy. Continuous monitoring of the strength of relationships is important to ensure success in achieving goals as well as collective impact.
