As psychoeducational eating disorder prevention programs have not been shown to reduce bulimic pathology, we developed and evaluated a dissonance-based intervention for high-risk populations.
Young women (N = 87) with body image concerns were randomized to this intervention, which involves verbal, written, and behavioral exercises requiring them to critique the thin-ideal, or to a healthy weight management control group. Participants completed a baseline, termination, and 4-week follow-up survey.
Participants in the dissonance intervention reported decreased thin-ideal internalization, body dissatisfaction, dieting, negative affect, and bulimic symptoms at termination and at 4-week follow-up. Unexpectedly, participants in the healthy weight management control group also reported some benefits.
Taken in conjunction with past findings, these preliminary results suggest that the dissonance intervention, and to a lesser extent the healthy weight management intervention, may reduce bulimic pathology and risk factors for eating disturbances.
由于心理教育性饮食失调预防项目尚未被证明能减少暴食症病理症状，我们针对高危人群开发并评估了一种基于认知失调的干预措施。
将87名存在身体意象问题的年轻女性随机分为接受该干预措施（包括要求她们批判瘦身理想形象的口头、书面和行为练习）的组，或健康体重管理对照组。参与者完成了基线、干预结束时和4周随访调查。
认知失调干预组的参与者在干预结束时和4周随访时报告称，对瘦身理想形象的内化、身体不满、节食、消极情绪和暴食症状均有所减轻。出乎意料的是，健康体重管理对照组的参与者也报告了一些益处。
结合过去的研究结果，这些初步结果表明，认知失调干预措施，以及在较小程度上的健康体重管理干预措施，可能会减少暴食症病理症状和饮食紊乱的风险因素。
