简要总结
This proposed pilot study will evaluate whether this body acceptance class produces greater reductions in eating disorder risk factor symptoms (pursuit of the thin ideal, body dissatisfaction, dieting, dietary restraint and negative affect), eating disorder symptoms, and future onset of eating disorders over 6-month follow-up in this population.
详细描述
Dozens of eating disorder prevention programs have been evaluated, but only the 4-hr Body Project has reduced eating disorder symptoms and future eating disorder onset over 3-4 year follow-up, produced larger reductions in outcomes than credible alternative interventions, been shown to engage the intervention target (valuation of the thin beauty ideal), and produced effects in trials from several independent teams. Although undergraduate peer-educator-led Body Project groups have produced larger reductions in outcomes than an eating disorder education video, an unmoderated Internet-based prevention program, and even clinician-led Body Project groups, it can be logistically difficult to schedule in-person Body Project groups with high school and college students. One solution to this key implementation barrier is to have peer educators deliver Body Project groups virtually over the Internet. A pilot trial in Sweden provided initial evidence that virtually-delivered peer-led Body Project groups produced greater reductions in eating disorder symptoms and future onset of eating disorders than an active expressive-writing intervention. The proposed pilot study will evaluate whether Body Project produces greater reductions in risk factor symptoms, eating disorder symptoms, and future onset of eating disorders in this population.
Participation in the intervention will last four weeks. Participants will be randomly assigned to the intervention condition or waitlist-control condition. Assessments will take place at pre-intervention, post-intervention, and 6 month follow up. Waitlist control participants will receive the intervention after they complete their post-test assessment.

研究组 & 干预措施
Peer Led Group Intervention
In the virtual peer-led group Intervention, participants voluntarily engage in verbal, written, and behavioral exercises in which they critique and discuss the costs of pursuing the thin-ideal ideal. The intervention is 4 sessions long (1-hr each) and is administered by trained peer facilitators who use an intervention script. Participants will be asked to complete weekly home exercises throughout the course of the intervention.
干预措施: Peer Led Group Intervention (Behavioral)
Wait-List Control
Participants will be placed on a wait list for four weeks, an equal span of time of participants in the peer led group intervention. At four weeks, participants will complete their post-test assessment, then receive the intervention.
结局指标
主要结局
Change over time in Body Dissatisfaction
时间窗: pre intervention obtained on intake, immediately post intervention, and 6-months after the conclusion of the intervention
Ten items from the Satisfaction and Dissatisfaction with Body Parts Scale assessed satisfaction with body parts with a response scale ranging from 1 = extremely dissatisfied to 6 = extremely satisfied
Change over time in Thin Ideal Internalization
时间窗: pre intervention obtained on intake, immediately post intervention, and 6-months after the conclusion of the intervention
The eight-item Ideal-Body Stereotype Scale-Revised will assess endorsement of the thin beauty ideal using a response scale ranging from 1 = strongly disagree to 5 = strongly agree.
次要结局
- Change over time in Negative Affect(pre intervention obtained on intake, immediately post intervention, and 6-months after the conclusion of the intervention)
- Change over time in Dieting(pre intervention obtained on intake, immediately post intervention, and 6-months after the conclusion of the intervention)
- Change over time in Eating Disorder symptoms(pre intervention obtained on intake, immediately post intervention, and 6-months after the conclusion of the intervention)
