Body shame is an established antecedent and maintaining factor of binge eating, beyond global negative affect and body weight, and partly through the effects of dietary restriction. These associations have mainly been established in women and are understudied in men. Body image flexibility, a concept from Acceptance and Commitment Therapy, may be a protective psychological process against the effects of negative body image on binge eating.
Using structural equation modeling and a non-clinical sample of 244 women and 185 men, this cross-sectional study tested an integrated model of the association between body shame and binge eating, mediated by dietary restriction and moderated by body image flexibility, controlling for depressive symptoms and BMI.
Body shame predicted binge eating in women but not in men, whereas depressive symptoms predicted binge eating in men but not in women. Body image flexibility moderated the association between body shame and binge eating in women.
These cross-sectional findings highlight the importance of considering gender differences in current negative affect models of binge eating, and further support the role of body image flexibility in attenuating the influence of body shame on binge eating in women. Longitudinal studies are required to examine the temporal dynamics between these variables.
除了整体负性情绪和体重外，身体羞耻感也是暴食的既定前提和维持因素，且部分通过节食的影响。这些关联主要在女性中建立，而在男性中研究较少。接纳与承诺疗法中的身体意象灵活性是一种对负面身体意象对暴食影响的保护心理过程。
本横断面研究使用结构方程模型和 244 名女性和 185 名男性的非临床样本，检验了身体羞耻感与暴食之间的综合模型，该模型由节食和身体意象灵活性调节，控制抑郁症状和 BMI。
身体羞耻感预测女性暴食，但不预测男性暴食，而抑郁症状预测男性暴食，但不预测女性暴食。身体意象灵活性调节了女性身体羞耻感与暴食之间的关系。
这些横断面研究结果强调了在当前暴食的负性情绪模型中考虑性别差异的重要性，并进一步支持了身体意象灵活性在减轻女性身体羞耻感对暴食影响方面的作用。需要进行纵向研究来检验这些变量之间的时间动态关系。
