Overview
Brief Summary
This study aims to test the effectiveness of an evidence-based eating- disorder prevention program specifically targeted for individuals with Type 1 Diabetes (T1D) compared to an educational control group. The Diabetes Body Project (DBP), is an adaptation of the Body Project which is the only eating disorder prevention program to have repeatedly produced effects when evaluated by independent researchers, produced stronger effects than credible alternative interventions, and affected objective outcomes. DBP has been adapted slightly for individuals with T1D who are at ultra-high risk for eating disorders. The study aims to test the effectiveness of the DBP of reducing body image concerns and reducing eating pathology and improving glycemic control.

Outcomes
Primary Outcomes
Percentage of Time With Blood Sugar in Range as a Measure of Glycemic Control
Time Frame: Three months following the 6-week intervention period
Participants wore a continuous-glucose monitor for 14 days as well as self-reported A1c levels. The percentage of time that participants had blood sugar in range (70 to 180 mg/dL) is reported.
Eating Disorder Symptoms
Time Frame: Assessed at week 6 (post-intervention) and three months following the 6-week intervention period
Participants completed a diagnostic interview using the semi-structured Eating Disorder Diagnostic Interview (EDDI) was used to assess eating disorder symptoms, including frequency of binge eating, vomiting, laxative/diuretic use, fasting, and excessive exercise, as well as degree of overvaluation of weight/shape, feeling fat, and fear of weight gain. Participants were also asked about distress regarding binge eating, rapid eating, eating until uncomfortably full, eating large quantities of food when not hungry, eating alone because of embarrassment, and feeling disgusted, depressed, or guilty after binge eating. The research assistant administering the interview was blinded to the person's condition. Scores range from 0 to over 100 for the most severe cases. Higher scores indicate higher levels of eating disorder symptoms. Items assessing symptoms in the past month were summed to form a composite.
Body Dissatisfaction (BS)
Time Frame: Week 6 (post-intervention) and three months following the 6-week intervention period
Assessed with the 10-item Body Dissatisfaction Scale which assesses dissatisfaction with various body parts. Each item is scored on a scale of 1 = extremely dissatisfied to 6 = extremely satisfied. Item scores were averaged to create an overall score (1 to 6). Lower scores indicate greater body dissatisfaction.
Thin Ideal Internalization
Time Frame: Week 6 (post-intervention) and three months following the 6-week intervention period
Assessed with the 8-item Ideal-Body Stereotype Scale-Revised which measures pursuit of the thin ideal. Each item is scored on a scale of 1 = strongly disagree to 5 = strongly agree. Item scores were averaged to create an overall score (1 to 5). Higher scores indicate greater belief in the thin-deal.
Diabetes-Specific Eating Pathology
Time Frame: Week 6 (post-intervention) and three months following the 6-week intervention period
Assessed with the 16-item Diabetes Eating Problem Survey-Revised. Each item is assessed on a scale of 0 = Never to 5= Always. Item scores were averaged to create an overall score (0 to 5). Higher scores indicate greater eating pathology specific to individuals with Type 1 Diabetes such as purposefully not taking enough insulin.
Diabetes-Specific Distress
Time Frame: Week 6 (post-intervention) and three months following the 6-week intervention period
Assessed with the 28-item Type 1 Diabetes Distress Scale which measures distress related to diabetes. Each item is assessed on a scale of 1 = Not a Problem to 6 = A Very Serious Problem. Item scores were averaged to create an overall score (1 to 6). High scores indicate greater distress that are related to living with Type 1 Diabetes.
Negative Affect
Time Frame: Week 6 (post-intervention) and three months following the 6-week intervention period
Negative affect will be assessed with the sadness, guilt, and fear/anxiety subscales (totaling 20 items) from the Positive Affect and Negative Affect Scale-Revised. Each item is scored on a scale of 1 = Not at All to 5 = Extremely. Item scores were averaged to create an overall score (1 to 5) Higher scores indicate greater negative affect.
Quality of Life (Well-Being)
Time Frame: Week 6 (post-intervention) and three months following the 6-week intervention period
Assessed with the 5-item World Health Organization Well-Being Index that measures health related quality of life. Each item is scored on a scale of 0 = At no Time to 5 = All of the Time. Item scores were averaged to create an overall score (0 to 5). Higher scores indicate greater well-being.
