The project was conducted entirely virtually, utilizing a structured process with engagement tools adapted from a prior Patient Partner Guide. It included three stages: (1) develop the virtual environment and adapt the engagement process and tools, (2) recruit and train co-creators and facilitators to test the process and tools collaboratively and make iterative improvements, and (3) implement these tools in ten-week group sessions. Project participants in the group sessions - adults with or caring for individuals with MCCs - were recruited from a previous national trial. They engaged in interactive activities such as needs assessments related to engagement, Affinity Diagrams, and Shared Lived Experiences. Results demonstrated success in two domains: (1) successful engagement in early stages of collaborative research as measured by recruitment (59 initial participants) and high levels of retention (89%) and participation (100% completion of initial assessment; 78–82% of other assessments and activities; positive qualitative evaluations) and (2) successful completion of a Partnering Guide for Research (PGR) and a prioritized research agenda for MCCs. The project is a demonstration of intentional, structured virtual engagement processes and supportive environments fostering equitable partnerships and trust while producing intended products. The PGR is a replicable implementation guide to be used by other teams seeking to integrate community voices into health research starting with a research agenda.
