What Difference does a Policy Brief Make?

Research has potential to improve the lives of the world’s vulnerable people if it is appropriately referred to in decision-making processes. While there is a significant industry of activity each year to communicate research findings little systematic research has tested or compared the effectiveness of such efforts either for changing beliefs or for prompting action. Using a randomised control design this study explored the effectiveness of one popular research communication tool a policy brief and queried whether different versions of a brief bring about different results. We find that the policy brief had little effect on changing the beliefs of readers who held strong prior beliefs on entering the study but had some potential to create evidence-accurate beliefs among readers holding no prior beliefs. Also when it comes to beliefs the impact of the policy brief seems to be independent of the specific form of the policy brief. However different versions of the brief (versions that include a research Opinion with or without a suggestion that the opinion is from an Authoritative source) do achieve different results when it comes to prompting actions. We find that other factors internal and external to the brief (gender of the reader reader’s self-perceived level of influence and the extent to which the reader feels ‘convinced’ by the brief) are also linked to action. This first-of-its-kind study has implications for how research communication experts design policy briefs how they understand and enable readers to act as knowledge brokers in their particular environment and how we evaluate research communication going forward.
