Advancing the science of dissemination and implementation in behavioral medicine: evidence and progress.

The enormous time lag between the discovery of new knowledge and its implementation poses a significant challenge to improving public health because of the very slow uptake into policy and practice. The field of dissemination and implementation research in behavioral medicine is receiving increased attention because of the keen interest in accelerating knowledge transfer from relevant research to improve the health and wellbeing of populations in many different settings, contexts, and countries around the world. This is particularly important in high-risk populations, resource-poor and developing regions of the world where the difference in health systems, languages, and cultures very significantly influences the translation of evidence into policy and practice. Moreover, demonstrating the broader societal and economic value of behavioral interventions in settings where they are implemented can further support the sustainability, uptake, and implementation of these findings in other settings and contexts. This special issue presents a series of empirical studies, reviews, and case studies that address dissemination, implementation, and translation issues in both developed and developing countries. Specifically, the learnings from the application of many and varied theories and research methodologies are very relevant for bridging the current division between research findings and their translation and uptake into policy and practice.
