Diabetes Journey: An Adolescent Adherence Barriers Intervention

Type 1 diabetes (T1D) treatment adherence is complex and involves glucose monitoring, counting carbohydrates, and intensive insulin delivery via injections or insulin pump in response to food intake, exercise, and illness to achieve near-normal blood glucose levels. Evidence demonstrates that adhering to T1D treatment is challenging, especially during adolescence. Non-adherence leads to suboptimal glycemic levels that severely compromise health and quality of life. Suboptimal adherence to T1D treatment regimen is common in >50% of adolescents and directly related to suboptimal glycemic control, increased risk of hospitalizations for diabetic ketoacidosis, and decreased health-related quality of life (HRQOL). The maximum benefits of current diabetes technology are limited by the knowledge, skills, adherence barriers, and non-adherence behaviors.10-14 Ultimately, adolescents have to overcome these barriers in order to benefit from technological advances. Thus, there is a clear need for behaviorally focused interventions to identify and reduce adherence barriers. The overall objective of this study is to identify adolescents with elevated adherence barriers and provide novel tailored mHealth intervention (Diabetes Journey) targeting these barriers. This study is two phases and includes a small pilot of up to 12 adolescents with type 1 diabetes (Phase 1) and a randomized controlled clinical trial (Phase 2). The randomized controlled clinical trial will examine feasibility, acceptability and preliminary efficacy of Diabetes Journey versus enhanced standard of care (control group) in approximately 256 adolescents with type 1 diabetes. Primary and secondary outcomes include adherence barriers, adherence, health-related quality of life and A1C. Satisfaction and acceptability will also be examined. Mediators and moderators will include executive functioning, diabetes distress, family conflict, depressive symptoms, fear of hypoglycemia and sleep.
