Human-centered design (HCD) is an approach to research that aims to facilitate participant engagement in research studies. Research Jam is the Patient Engagement Core of the Indiana Clinical and Translational Sciences Institute (Indiana CTSI) that applies HCD to health research. The objective of this project is to assess the impact and efficacy of the HCD approach in health research. This project follows-up with previous investigators who have completed a project with Research Jam to measure impact on investigators’ attitudes towards HCD and participant engagement as well as the efficacy and implementation of the project-specific tools and deliverables that resulted from the work with Research Jam.
