This report consists of the second phase of a social network analysis of researchers in the United Kingdom who have authored gambling harm studies. Phase 1 was focused on researchers with an institutional affiliation in the UK and their connections to other UK-based researchers. In Phase 2, the analysis is extended to include their coauthors affiliated with research institutions in other countries. The goal is to better understand the strength of existing links among researchers nationally and internationally with expertise in specific areas of gambling harm. The analysis is based on the Framework of Harms, outlined in Measuring gambling-related harms: A framework for action (Wardle et al, 2018). To advance the National Strategy to Reduce Gambling Harms effectively, a strong evidence base is required to support each of the three primary factors and eight related subfactors in the Framework.
