The goal of this clinical trial is to learn if the Discovery Program can help improve diabetes management in adolescents and young adults with type 1 diabetes (T1D). The main questions it aims to answer are: Does the Discovery Program lead to better glycemic control as measured by HbA1c levels? How does participation in the Discovery Program affect diabetes distress and self-management skills? Researchers will compare participants in the Discovery Program to those receiving standard diabetes care to see if the program has a positive effect on diabetes management. Participants will: Engage in a 3-month intervention that includes personalized mobile health communications and clinician support. Complete surveys and assessments at the beginning of the study, and again at 3 and 6 months. Allow the study team to access their electronic health records for additional data on diabetes management.
