Cincinnati Cohort Biomarker Programs (CCBP) are conducting qualitative research regarding biomarkers in patients with neurodegenerative diseases. The program is struggling to attract more participants and retain existing participants. This research investigates how to improve the engagement of participants in the program. The research conducted interviews with researchers from CCBP to gain insight into the program and subjects. It is found that a monetary incentive is provided but is not perceived by participants as necessary. In addition, participants are looking for more information regarding the disease and a connection to a community of those who share a similar experience. The Biomarker Idea Generation (BIG) Game is created and used as a co-creation method to generate ideas. This research proposes a new type of incentive in the form of an accessible physical input device connected to digital services. They are perceived to provide a better value than a monetary incentive and further the perception of the program. Due to time constraints, in-depth evaluation in terms of accessibility and production has not yet been reviewed. In the next step, the research is planned to evaluate the accessibility, price structure, cost-to-benefit ratio, and development timeline of the device.
