NCT03845465

Brief Summary

The treatment regimen for type 1 diabetes is complex and demanding, and many adolescents experience diabetes distress related to the daily demands of diabetes care, which can cause problems with diabetes management and glycemic control. The proposed study will conduct a multisite, randomized trial to test the effects of a positive psychology intervention aimed at treating diabetes distress and improving glycemic outcomes. The potential benefits include helping adolescents achieve better glycemic control, improved self-management, and psychosocial outcomes
