摘要

目的:消极情绪是进食障碍维持模型的核心;确定这种联系的内在机制可为特定治疗目标提供依据。本研究评估了哪些情绪(即苦恼、恐惧和道德情绪)与感觉自己胖有最密切的联系,并测试了感觉自己胖是这些情绪与限制性进食或暴饮暴食之间关系的纵向中介(https://osf.io/3d5cq/)。方法:社区成年人(N = 714,M[SD] 年龄 = 41.5[13.7],84.6% 为女性,85.9% 为白人)提供了基线、3 个月和 6 个月随访数据。相对权重分析检验了哪些情绪类别与感觉自己胖表现出最强的纵向关系。交叉滞后面板模型检验了感觉自己胖是情绪与饮食失调行为之间关系的中介:结果:苦恼和道德情绪是预测感觉自己胖的最强情绪因素。感觉肥胖预测暴饮暴食(P's 讨论:感觉肥胖与暴饮暴食有关联吗?感觉自己胖与暴饮暴食有关,而与限制饮食无关,这突出了维持模型中特异性的重要性。由于 "感觉自己胖 "的中介效应是由体型决定的,因此与体型相关的因素(如内化的体重耻辱感)可能是负面情绪与进食障碍行为之间关系的更相关的中介因素。未来有关 "感觉自己胖 "的研究应该对体型进行调整。

Testing “Feeling Fat” as a Mediator of the Longitudinal Relationship Between Negative Emotions and Eating Disorder Behaviors

Objective

Negative affect is central to eating disorder maintenance models; identifying mechanisms underlying this link may inform specific treatment targets. The current study evaluated which emotions (i.e., distress, fear, and moral emotions) were most strongly linked to feeling fat and tested feeling fat as a longitudinal mediator of the relationship between these emotions and restricting or binge eating (https://osf.io/3d5cq/).

Method

Community adults (N = 714, M[SD] age = 41.5[13.7], 84.6% female, 85.9% white) provided data at baseline, 3-month, and 6-month follow-up. Relative weights analysis examined which emotion categories exhibited the strongest longitudinal relationships with feeling fat. Cross-lagged panel models tested feeling fat as a mediator of the relationship between emotions and eating disorder behaviors.

Results

Distress and moral emotions were the strongest emotional predictors of feeling fat. Feeling fat predicted binge eating (p's < 0.001), but not restricting (p's ≥ 0.832), in random effects cross-lagged panel models. Feeling fat partially mediated the longitudinal relationship between distress and binge eating (p = 0.044); however, this effect became nonsignificant after adjusting for BMI (p = 0.354). Feeling fat did not mediate relationships between moral emotions and binge eating or between either distress or moral emotions and restricting (p's ≥ 0.638).

Discussion

Feeling fat was associated with binge eating, not restricting, highlighting the importance of specificity in maintenance models. Because the mediating effect of feeling fat was accounted for by body size, factors associated with body size, such as internalized weight stigma, may be more relevant mediators of the relationship between negative emotions and eating disorder behaviors. Future research on feeling fat should adjust for body size.

期刊介绍: Articles featured in the journal describe state-of-the-art scientific research on theory, methodology, etiology, clinical practice, and policy related to eating disorders, as well as contributions that facilitate scholarly critique and discussion of science and practice in the field. Theoretical and empirical work on obesity or healthy eating falls within the journal’s scope inasmuch as it facilitates the advancement of efforts to describe and understand, prevent, or treat eating disorders. IJED welcomes submissions from all regions of the world and representing all levels of inquiry (including basic science, clinical trials, implementation research, and dissemination studies), and across a full range of scientific methods, disciplines, and approaches.
