Evaluating stakeholder engagement can capture what meaningful engagement in research entails, how it develops, and how it is experienced by all collaborators. We conducted a scoping review of recent approaches for evaluating engagement in research and present a descriptive overview of our findings. We searched peer-reviewed journal articles published worldwide in English between January 2013 and June 2018. Our final sample consisted of 17 articles. Various approaches for evaluating stakeholder engagement were identified including qualitative approaches, surveys and engagement logs. We identified evaluation approaches that varied in quality, detail and methods. Valid, systematic and inclusive approaches that are developed with research partners and are inclusive of diverse perspectives are an important area for future research.
