iACT for eating disorders in Type 1 Diabetes - Clinical Trial

What is the Purpose of this Study?

We are doing this study to test a new intervention for people with type 1 diabetes who also have disordered eating. We hope the strategy we are testing in this study can improve diabetes management and decrease eating disorder symptoms and emotional distress.

What is the Condition Being Studied?

Type 1 Diabetes and Disordered Eating

Who Can Participate in the Study?

Adults ages 16-50 who:

  • Are diagnosed with type 1 diabetes
  • Independently manage their T1D
  • Experience signs/symptoms of disordered eating, including any of the following: overeating or binge eating, skipping doses of insulin, or emotional distress about body weight or body image

What is Involved?

If you choose to join the study, we will randomly assign you (like a coin flip) to either receive standard diabetes education along with your usual care or to receive the experimental study intervention.

No matter your assignment, during the course of the study you will:

  • Be enrolled for 3 months of active study treatment with 6 months of follow-up
  • Complete individual counseling sessions with a health care provider (typically once a week for the first 3 months)
  • Complete assessments at the beginning of the study, 6 weeks, end of the study, 3 months after the end of the study, and 6 months after the end of the study

The study assessments can include:

  • Diagnostic interviews
  • Surveys
  • Brief computer tests of attention, memory, and heart rate variability
  • Blood draws to check hemoglobin A1C
  • Use of continuous glucose monitoring (using the Dexcom G6 Pro system)
  • Actigraphy (an ActiLife watch that tracks activity and sleep)
