We conducted a controlled randomized preliminary trial of an expanded online version of the Body Project (n = 46) compared to an assessment-only control condition (n = 36) via a longitudinal design (baseline, postintervention, 2-month follow-up) in a community sample of women (N = 82) with clinical (n = 53) and subclinical (n = 29) eating disorder symptoms.
The traditional content of the Body Project was modified to include verbal, written, and behavioral exercises designed to dissuade objectification and maladaptive social comparison and adapted to an online format. Body dissatisfaction, self-esteem, self-objectification, thin-ideal internalization, maladaptive social comparison, trait anxiety, positive affect, negative affect, and eating disorder symptomatology were evaluated in the control and the online expanded Body Project condition at baseline, postintervention, and 2-month follow-up.
A 2 (condition: online expanded Body Project, control) × 3 (time: baseline, postintervention, 2-month follow-up) mixed factorial multivariate analysis of variance (MANOVA) was conducted to examine statistically significant group differences. As predicted, results indicated a statistically significant condition × time interaction.
Participants in the expanded online Body Project condition showed significant reductions in eating disorder symptoms and several associated psychological risk correlates from baseline to postintervention and follow-up; contrary to predictions, eating disorder symptoms and risk correlates were not significantly lower in the online expanded Body Project condition compared to the waitlist control condition at postintervention or 2-month follow-up.
我们通过纵向设计（基线、干预后、2个月随访），在一个包含有临床（n = 53）和亚临床（n = 29）饮食失调症状的女性社区样本（N = 82）中，对扩展版在线身体项目（n = 46）与仅进行评估的对照条件（n = 36）进行了一项对照随机初步试验。
对身体项目的传统内容进行修改，纳入旨在劝阻身体物化和适应不良的社会比较的言语、书面和行为练习，并将其改编为在线形式。在基线、干预后和2个月随访时，对对照组和在线扩展身体项目组的身体不满、自尊、自我物化、瘦身理想内化、适应不良的社会比较、特质焦虑、积极情绪、消极情绪和饮食失调症状进行评估。
进行了一项二因素（条件：在线扩展身体项目、对照）×三因素（时间：基线、干预后、2个月随访）混合因子多变量方差分析（MANOVA），以检验具有统计学意义的组间差异。正如预期的那样，结果显示存在具有统计学意义的条件×时间交互作用。
从基线到干预后及随访，参与扩展版在线身体项目组的饮食失调症状及一些相关心理风险因素显著降低；与预测相反，在干预后或2个月随访时，在线扩展身体项目组的饮食失调症状及风险因素与等待名单对照组相比并没有显著降低。
