Abstract
This research case study will discuss the process of engaging in knowledge exchange utilising an action research methodology on a project to improve services for older lesbian, gay, bisexual and transgender (LGBT) people in London, UK. It will begin by explaining what is meant by knowledge exchange and impact in social science research. It will then outline what action research is and how it can be related to knowledge exchange. The methodology of the project will then be explained and critically considered. Overall, the aim of this article is to explain why knowledge exchange action research (KEAR) is useful to enable social scientific research findings to have a social impact and to discuss what can be learned in a real-life project, including the sorts of problems that arise and how they can be resolved, and that sometimes provoke new ideas.
