Reciprocal peer support, where two participants in a self-care support program are matched as peer partners, has demonstrated benefits in management of type 2 diabetes (T2D). Optimizing adaptive interventions using study designs such as sequential multiple assignment randomized trials (SMARTs) necessitates randomizing participants to interventions or intervention components. No prior work using a SMART has randomized participants between peer support (a dyadic intervention) and other components which may break up peer partners mid intervention.
In the first webinar of CADIO's Fall 2025 Series, Dr. McKenzie Roddy, assistant professor at Vanderbilt University Medical Center, will describe the design processes of an upcoming pilot SMART randomizing adults with T2D to family and peer support. She and her team sought feedback from end users to understand the best way to facilitate peer matching and re-matching during the dyadic SMART, worked with study statisticians to inform their randomization process, and consulted with study coordinators regarding best practices for recruitment and enrollment. The resulting study design will be implemented this fall and in the future they will report on the feasibility and acceptability of the design and protocol for the dyadic SMART.
