这项研究的目的是复制和扩展先前试验的结果，该试验调查了2种同伴主导的饮食失调预防干预措施在减少本科女性饮食失调风险因素方面的有效性（C。B。贝克尔湖，澳-地M. Smith，& A. C. Ciao，2006）。为了通过允许调查差异反应来扩展先前研究的结果，作者随机分配了更大样本的高风险和低风险姐妹会成员（N = 188;年龄M = 18.64岁，范围= 18-21; 20%少数民族），在自然主义条件下进行认知失调（CD）或媒体宣传（MA）干预。干预措施提供了训练有素的姐妹会同行领导人，包括两个2小时的小组会议。参与者在治疗前、治疗后、7周随访和8个月随访时完成了评估进食障碍风险因素的问卷调查。结果表明，这两种干预措施都减少了8个月时的瘦理想内化，身体不满，饮食限制和贪食症病理学，尽管高风险和低风险参与者的反应有所不同。CD和MA通常对高风险参与者有效;然而，只有CD似乎对低风险参与者有益。研究结果进一步支持了在基于不和谐的预防中使用同伴领导者的可行性。
The aim of this study was to replicate and extend results of a previous trial that investigated the effectiveness of 2 peer-led eating disorders prevention interventions in reducing eating disorder risk factors in undergraduate women (C. B. Becker, L. M. Smith, & A. C. Ciao, 2006). To extend findings from the previous study by allowing for investigation of differential response, the authors randomly assigned a larger sample of both higher and lower risk sorority members (N = 188; age M = 18.64 years, range = 18-21; 20% minority) to either a cognitive dissonance (CD) or a media advocacy (MA) intervention under naturalistic conditions. Interventions were delivered by trained sorority peer leaders and consisted of two 2-hr group sessions. Participants completed questionnaires that assessed eating disorder risk factors at pretreatment, posttreatment, 7-week follow-up, and 8-month follow-up. Results indicate that both interventions reduced thin-ideal internalization, body dissatisfaction, dietary restraint, and bulimic pathology at 8 months, although higher and lower risk participants responded somewhat differently. Both CD and MA generally appeared effective for higher risk participants; only CD, however, appeared to benefit lower risk participants. Results further support the viability of using peer leaders in dissonance-based prevention.
