RecruitingBehavioural interventionAchieving Health in Emerging Adults With Diabetes (AHEAD) Program: A Clinical Trial Designed to Understand if Participation in a Clinical Program Developed Specifically to Support Emerging Adults With Type 1 Diabetes Leads to Improved Diabetes Outcomes.The goal of this study is to determine whether the Achieving Health in Emerging Adults with Diabetes (AHEAD) Program helps emerging adults with type 1 diabetes improve their blood glucose management during the transition from pediatric to adult care. Participants will be randomized to receive Usual Care or the AHEAD Program, which provides tailored support to emerging adults to build autonomy and competence to facilitate independent diabetes management. Researchers will compare changes in glycemia and participant-reported outcomes between groups.
