Bobbi Carothers presented at the 5th Annual National Institutes of Health (NIH) Conference on the Science of Dissemination and Implementation: Research at the Crossroads on March 19, 2012 in Bethesda, Maryland. The goal of this conference is to provide a forum to engage researchers, evaluators, and implementers in identifying approaches to advance dissemination and implementation science. Carothers presented findings from the Implementation of Evidence-based Guidelines by State Tobacco Control Programs evaluation. Her presentation, entitled “Network Centralization and Predicting Dissemination of Evidence-Based Guidelines in Eight State Tobacco Control Programs” describes how this evaluation utilized social network analysis to examine communication, collaboration, and dissemination patterns in state tobacco control networks. By using social network analysis and exponential random graphic modeling (ERGM) to build statistical models of the networks, Carothers and other CPHSS staff found that higher levels of communication and collaboration predict dissemination of evidence-based guidelines and that state lead agencies play a critical role in controlling the flow of information in state tobacco control programs. Based on these findings, Carothers and the evaluation team emphasize the importance of using existing communication and collaboration networks to disseminate information. The team is currently developing a paper to further disseminate these findings. View her presentation here.
