感觉肥胖，是一种超重的主观感受，并不总是与实际体重相符，在饮食失调患者中常有报告。研究表明，感觉肥胖与内感受觉知的缺陷有关，即与身体状态相关的信号的感知和整合。相关地，近期的研究将感觉肥胖与情感结构联系起来，比如抑郁症状和内疚感。当前的研究探讨了感觉肥胖、自我报告的和客观的内感受觉知、内疚、述情障碍以及抑郁症状之间的独特关系。
女性本科生（N = 128）完成了《饮食失调检查表问卷》的第11项、《多伦多述情障碍量表》、《正负性情绪量表》的内疚分量表以及《贝克抑郁量表 - II》。参与者还完成了两项内感受觉知测量：一项心跳感知任务和《内感受觉知多维评估》。
所有收集的测量指标解释了感觉肥胖的56%的变异性。抑郁症状、自我报告的内感受觉知以及体重指数（BMI）对感觉肥胖的变异性有显著影响。相对权重分析显示，抑郁症状对感觉肥胖的变异性影响最大（19%）。在控制了体重指数（BMI）后，这一发现仍然显著，体重指数对感觉肥胖的变异性也有显著影响（25%）。
我们的结果重复了先前的发现，即抑郁症状与感觉肥胖显著相关，并通过纳入内感受觉知、内疚和述情障碍的作用扩展了这项研究。在摄入性评估中对感觉肥胖的认可可能会提醒临床医生评估抑郁症状，并且在治疗中关注抑郁症状可能会改善感觉肥胖。

Feeling fat, a subjective feeling of being overweight that does not always correspond to actual body weight, is commonly reported in patients with an eating disorder. Research suggests that feeling fat relates to deficits in interoceptive awareness, the perception and integration of signals related to body states. Relatedly, recent work has linked feeling fat to affective constructs, such as depressive symptoms and guilt. The current study explores the unique relationships between feeling fat, self-reported, and objective IA, guilt, alexithymia, and depressive symptoms. Female undergraduates (N = 128) completed the 11th item of the Eating Disorder Examination Questionnaire, the Toronto Alexithymia Scale, the Guilt subscale of the Positive and Negative Affect Schedule, and the Beck Depression Inventory-II. Participants also completed two IA measures: a heartbeat perception task and the Multidimensional Assessment of Interoceptive Awareness. All collected measures explained 56% of the variability in feeling fat. Depressive symptoms, self-reported IA, and BMI accounted for significant variability in feeling fat. Relative weights analyses revealed that depressive symptoms accounted for the most variability in feeling fat (19%). This finding remained significant after controlling for BMI, which also accounted for significant variability in feeling fat (25%). Our results replicate previous findings that depressive symptoms relate significantly to feeling fat and extend this work by incorporating the role of interoceptive awareness, guilt, and alexithymia. Endorsement of feeling fat during an intake assessment may alert clinicians to assess for depressive symptoms, and focusing on depressive symptoms in treatment may improve feeling fat.
