The purpose of this study is to assess how psychosocial functioning and transition readiness (health knowledge and self-reported health-related skills) of young adults (aged 18-24) with Type 1 Diabetes (T1D) and their parents impact health outcomes before they transition to adult diabetes care. Transition of health care from pediatric to adult care systems is a complex process and is often a challenge for young adults. These transition barriers lead to gaps in healthcare, worsening of glycemic control, and increased hospitalizations/emergency room utilization. Initial program development efforts to prepare young adults for transition were developed at Cincinnati Children's Hospital Medical Center (CCHMC) based on best practice recommendations in the literature. The psychosocial correlates of health outcomes in this population are not well studied, though. Nor is it known whether these diabetes education interventions impact transition to adult care over time. The investigators will study how psychosocial factors (e.g., self-efficacy, depression, distress, quality of life, adherence, and risky behaviors) impact health outcomes (e.g., glycemic control) over a one year period, within the context of the current diabetes education transition program at Cincinnati Children's Hospital Medical Center (CCHMC) for young adults with T1D and their parents.
