Summary
This study is a comprehensive, multicomponent behavioral intervention package (ONBOARD; OvercomiNg Barriers & Obstacles to Adopting Diabetes Devices). ONBOARD will provide adults with T1D the skills to maximize benefit and minimize daily interference from barriers associated with Continuous Glucose Monitoring (CGM) and increase readiness for closed loop.
