Interoceptive awareness is known to be impaired in eating disorders. To date, it has remained unclear whether this variable is related to the construct of interoceptive sensitivity. Interoceptive sensitivity is considered to be an essential variable in emotional processes. The objective of the study was to elucidate this potential relationship and to clarify whether general interoceptive sensitivity is reduced in anorexia nervosa.
Using a heartbeat perception task, interoceptive sensitivity was assessed in 28 female patients with anorexia nervosa and 28 matched healthy controls. Questionnaires assessing interoceptive awareness (EDI) and several other variables were also administered.
Patients with anorexia nervosa displayed significantly decreased interoceptive sensitivity. They also had more difficulties in interoceptive awareness.
In addition to a decreased ability to recognize certain visceral sensations related to hunger, there is a generally reduced capacity to accurately perceive bodily signals in anorexia nervosa. This highlights the potential importance of interoceptive sensitivity in the pathogenesis of eating disorders.
已知进食障碍患者的内感受性觉知受损。迄今为止，尚不清楚该变量是否与内感受性敏感性这一概念相关。内感受性敏感性被认为是情绪过程中的一个重要变量。本研究的目的是阐明这种潜在关系，并明确神经性厌食症患者的一般内感受性敏感性是否降低。
采用心跳感知任务，对28名神经性厌食症女性患者和28名匹配的健康对照者进行内感受性敏感性评估。还发放了评估内感受性觉知（EDI）和其他几个变量的问卷。
神经性厌食症患者的内感受性敏感性显著降低。他们在内感受性觉知方面也有更多困难。
除了识别与饥饿相关的某些内脏感觉的能力下降外，神经性厌食症患者准确感知身体信号的总体能力也有所降低。这突出了内感受性敏感性在进食障碍发病机制中的潜在重要性。
