Small worlds or worlds apart? Using network theory to understand the research-practice gap

Abstract

The implementation of effective community interventions can be challenging for many reasons, including financial and time costs, lack of infrastructure, local contextual variations, and barriers to fidelity. But, prior to all of these is the challenge of limited information exchange between the researchers developing interventions and the practitioners implementing them, or the so-called research-practice gap. In this paper, we use network theory and review a dozen small world experiments to understand the research-practice gap, identifying three key lessons: (1) spatial and social distances are related to the severity of the gap, (2) social boundaries may lead to echo chambers and closed loops, and (3) wider gaps reduce the likelihood of successful information exchange. From these lessons, we recommend that researchers and practitioners should rely on the assistances of information brokers who know people they do not know and who are different from themselves.
