Changing the T1DE (Type 1 Diabetes Eating Disorders): A Randomized Controlled Trial Comparing Acceptance and Commitment Therapy (ACT) to Supportive Diabetes Counseling and a Waitlist Control
Duke University
Summary
The goal of this clinical trial is to test whether a new intervention works to treat eating disorders in type 1 diabetes. Participants are assigned to one of the following: (1) Acceptance and Commitment Therapy (ACT), (2) Supportive Diabetes Counseling, or (3) a 6-month Waitlist Control. Participants in the ACT and Supportive Diabetes Counseling conditions complete 12 sessions over 12-16 weeks and use their mobile phone between sessions to increase engagement and reinforce learning. The main questions are: Does treatment improve glycemic levels, eating disorder symptoms, diabetes management and diabetes distress? Does one treatment do better than the other? How do the treatments work, if they work, and for whom? Participants complete assessments that include wearing a continuous glucose sensor and activity watch, and get a blood draw to determine HbA1c. They also complete diagnostic interviews, surveys and computer tests of attention and things like heart rate and reaction time. These assessments help us better understand the types of changes that are happening and how they might influence health and well-being.
Description
This is a randomized controlled trial comparing an Acceptance and Commitment Therapy (ACT) protocol to supportive diabetes counseling (SDC) and a Waitlist Control (WLC) for individuals with type 1 diabetes and disordered eating (or T1DE). Both active conditions are tailored to the needs of individuals living with T1D and the unique conditions under which the eating disorder developed and is maintained. Participants will be 161 individuals with T1D, between the ages of 16-50, with binge-purge eating disorders (EDs), including threshold and subthreshold bulimia nervosa, binge eating disorder and…
