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.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 16-50 with type 1 diabetes and binge-purge eating disorders who can independently manage their diabetes.

Not a fit: Patients with current suicidal ideation, anorexia nervosa, or those who are non-English speaking may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve glycemic control and eating disorder symptoms in patients with type 1 diabetes.

How similar studies have performed: While this approach is innovative, similar interventions in related areas have shown promise, indicating potential for success.
