Summary
DiaBetter Together is a strengths-based peer support intervention delivered to young adults (age 17-25) by trained Peer Mentors (age 20-35) during the transition between pediatric and adult diabetes care. The aims of this proposed randomized controlled trial are to evaluate the impact of the intervention on glycemic control (primary), time to first adult care visit, adherence, and psychosocial outcomes (secondary) in young adults with T1D after 12 months.
