This article reports results from a survey of academic social scientists in Australian universities on reported levels of research utilisation by non-academic users. Using the scale of research utilisation we examine levels of research impact and explore a range of variables to understand factors influencing the use of academic social science research by policy-makers and practitioners. The results indicate that research uptake is enhanced through mechanisms that improve research transfer and the intensity of interactions between academic researchers and users. Our findings provide insights into how the impact of social science research can be improved and draws attention to factors that need to be considered in efforts to evaluate and enhance the impact of academic social research.
