About this study
Official title: Evaluating an Eating Disorder Prevention Program for Young Women With Type 1 Diabetes
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Diabetes Body ProjectBehavioural
The Diabetes Body Project (DBP) is an adapted version of the Body Project Prevention program designed specifically for individuals with Type 1 Diabetes. DBP consists of six weekly, one-hour long sessions. Group participants complete the exercises from the original Body Project and also new diabetes-specific content, drawn from Olmsted et al. (2002) that is delivered in a dissonance-based interactive format with Socratic questions from group leaders encourage participants to generate their own answers.
Educational ControlBehavioural
We selected a T1D management/Eating disorder psychoeducational comparison condition previously tested (Olmsted et al., 2002) to control for expectancy effects and demand characteristics. To match the Diabetes Body Project, the educational lectures by Dr. Olmsted will be delivered in 6 1-hour blocks. Topics include basic information about the various EDs, complications of ED behaviors, diabetes and body image, effects of dieting on blood glucose, and the risk of complications.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Time With Blood Sugar in Range as a Measure of Glycemic Control
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.
Measured: Three months following the 6-week intervention period
Eating Disorder Symptoms
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.
Measured: Assessed at week 6 (post-intervention) and three months following the 6-week intervention period
Body Dissatisfaction (BS)
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.
Measured: Week 6 (post-intervention) and three months following the 6-week intervention period
Thin Ideal Internalization
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.
Measured: Week 6 (post-intervention) and three months following the 6-week intervention period
Diabetes-Specific Eating Pathology
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.
Measured: Week 6 (post-intervention) and three months following the 6-week intervention period
Diabetes-Specific Distress
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.
Measured: Week 6 (post-intervention) and three months following the 6-week intervention period
Negative Affect
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.
Measured: Week 6 (post-intervention) and three months following the 6-week intervention period
Quality of Life (Well-Being)
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.
Measured: Week 6 (post-intervention) and three months following the 6-week intervention period

Questions about this trial
What is this clinical trial studying?
A study testing Diabetes Body Project in people with Eating Disorders and Type 1 Diabetes, run by Stanford University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 7 Jan 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Time With Blood Sugar in Range as a Measure of Glycemic Control (time frame: Three months following the 6-week intervention period). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05264376, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2026; AzTrials last refreshed its copy on 26 Oct 2026.
