Because psychoeducational primary prevention programs for eating disorders have met with little success, this preliminary experiment tested a dissonance-based targeted preventive intervention.
Female undergraduates (N = 30) with elevated body image concerns were assigned to a three-session intervention, wherein they voluntarily argued against the thin ideal, or a delayed-intervention control condition. Participants completed a baseline, termination, and a 1-month follow-up survey.
The intervention resulted in a subsequent decrease in thin-ideal internalization, body dissatisfaction, dieting, negative affect, and bulimic symptomatology, with most changes remaining at the 1-month follow-up.
These preliminary results suggest that this dissonance-based targeted prevention intervention reduces bulimic pathology and known risk factors for eating disturbances, and provide experimental support for the claim that thin-ideal internalization contributes to body dissatisfaction, dieting, negative affect, and bulimic symptoms.
由于针对饮食失调的心理教育初级预防项目成效甚微，本初步实验测试了一种基于认知失调的针对性预防干预措施。
将身体意象问题较为严重的女性本科生（N = 30）分为两组，一组接受为期三节课的干预，期间她们自愿反对瘦即美的观念，另一组为延迟干预对照组。参与者完成了基线、干预结束时以及1个月后的随访调查。
干预后，参与者对瘦即美的内化程度、身体不满、节食行为、消极情绪和暴食症状均有所减少，且大部分变化在1个月随访时依然存在。
这些初步结果表明，这种基于认知失调的针对性预防干预可减少暴食病理及已知的饮食失调风险因素，并为瘦即美的内化会导致身体不满、节食行为、消极情绪和暴食症状这一观点提供了实验支持。
