Study Comparing Acceptance and Commitment Therapy to Supportive Diabetes Counseling and a Waitlist Control for Eating Disorders in Type 1 Diabetes

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.

Naltrexone Neuroimaging in Teens With Eating Disorders

Using a randomized, placebo-controlled, crossover study, this study will evaluate functional magnetic resonance imaging (fMRI) as a pharmacodynamic biomarker of opioid antagonism in adolescents with eating disorders. The hypothesis is that fMRI will be able to detect acute reward pathway modulation by naltrexone (an opioid antagonist) in pre-defined regions of interest (anterior cingulate cortex, nucleus accumbens, dorsolateral prefrontal cortex).

Targeting Social Function in Anxiety and Eating Disorders

Social processing and cognition are often altered in patients with eating disorders. The goal of this clinical trial is to assess two different social therapeutic interventions -- one educational, one interactive -- for their effectiveness in improving clinical outcomes in patients with eating disorders. Patients in both interventions will receive education about social function in eating disorders, but those in the interactive treatment group will complete an additional collaborative art task. Participants will: * attend a baseline study visit to complete clinical interviews, cognitive testing, and behavioral tasks * complete a pre-intervention assessment with questionnaires * attend eight sessions of their assigned treatment group over the course of 12 weeks * complete three virtual follow-up assessments 4, 8, and 12 months from their baseline * attend a final study visit to repeat some clinical interviews, cognitive testing, and behavioral tasks Researchers will compare changes in eating disorder, mood, and anxiety symptoms as well as test results from baseline and final study visits for each group to see if * patients can be treated effectively with education alone or if an interactive group component produces additional benefits * cognitive and behavioral task performance are associated with recovery or illness state.
