What this trial studies

This project is a randomized controlled trial evaluating a novel mobile health intervention (iACT) aimed at treating eating disorders in patients with type 1 diabetes. The study will involve 128 participants aged 16-45 who have binge-purge eating disorders, and they will be randomly assigned to receive either iACT or usual care. Assessments will be conducted at baseline and every three months over a nine-month period, focusing on glycemic control, eating disorder symptoms, and diabetes management. The study also aims to explore the biobehavioral mechanisms of change and predictors of treatment response.
