Eating disorders (EDs) are a group of illnesses associated with significant psychological and physiological consequences. Overall, only 20% of individuals with EDs receive treatment and treatment is effective for only about 25-35% for those who receive care. The development and implementation of effective prevention approaches for those at risk is therefore pivotal. The Body Project is the most effective ED prevention program for at-risk females according to meta-analyses, but reach has been limited since delivery has traditionally been in-person. Further research is warranted to examine cost-effective and easily accessible approaches to increase scalability and potential for broad implementation. With this application, the investigators therefore propose to examine the effectiveness of the Body Project in young females, a high-risk group, with the following main novel aspects: i) virtually-delivered Body Project groups to maximize reach; ii) peer-led versus clinician-led virtually-delivered Body Project groups; iii) the inclusion of objective measures to assess engagement of intervention targets (i.e., mediator).

Change over time in eating disorder symptoms
Assessed with the 28-item self-report Eating Disorder Examination Questionnaire (EDE-Q). Responses range from 0-6, whith higher scores indicating more severe eating disorder psychopathology
Time frame: Baseline/pretest, posttest right after intervention (an average of 8 weeks), and at follow-up after 6-months, 1-year, and 2-years
Rate of eating disorder onset
Assessed with the eating disorder diagnostic interview Eating Disorder Assessment-5 (EDA-5). This is a semi-structured clinician-led diagnostic interview, based on the diagnostic criteria in the diagnostic manual DSM-5, and is efficient to determine eating disorder diagnostic status. This outcome will be used to determine proportion of participants with an eating disorder diagnosis.
Time frame: Baseline/pretest, 1-year, and at 2-years
Change over time in Body dissatisfaction
Assessed with the 10-item Body Dissatisfaction Scale (BDI; Berscheid et al., 2973) which assesses dissatisfaction with various body parts. Each item is scored on a scale of 1 = extremely dissatisfied to 5 = extremely satisfied. Lower scores indicate greater body dissatisfaction
Time frame: Baseline/pretest, posttest right after intervention (an average of 8 weeks), and at follow-up after 6-months, 1-year, and 2-years
Change over time in thin-ideal internalization
Assessed with the 8-item Ideal-Body Stereotype Scale-Revised (Stice et al., 2017) which measures pursuit of the thin ideal. Each item is scored on a scale of 1 = strongly disagree to 5 = strongly agree. Higher scores indicate greater belief in the thin-deal.
Time frame: Baseline/pretest, posttest right after intervention (an average of 8 weeks), and at follow-up after 6-months, 1-year, and 2-years
Negative affect
20 negative items from the Positive and Negative Affect Schedule - Revised (PANAS-X) (Watson \& Clark, 1992) to measure negative affect. Higher scores indicate higher levels of negative affect. Responses range from 1-5
Time frame: Baseline/pretest, posttest right after intervention (an average of 8 weeks), and at follow-up after 6-months, 1-year, and 2-years
Change over time in appearance ideals and perceived pressures
Assessed with the Attitudes Towards Appearance Questionnaire (SATAQ-4R) (Schaefer et al., 2017). A total of 31 items are included, and responses range from 1-5. Higher scores indicate higher levels of internalization/pressures
Time frame: Baseline/pretest, posttest right after intervention (an average of 8 weeks), and at follow-up after 6-months, 1-year, and 2-years
