Diabetes Body Project
Diabetes Body Project: 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 Control Group
Educational Control: 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.

PRIMARY outcome

Timeframe: 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.
