自我报告研究表明，神经性暴食症(BN)患者在内感意识方面存在困难。事实上，内感缺陷在BN恢复后可能持续存在，可能是导致BN症状发展的生物学特征。然而，到目前为止，还没有研究直接评估BN患者或康复患者的感觉间敏感性，或在检测和感知体内线索方面的准确性。9名从BN中康复的女性和10名健康对照女性完成了心跳感知任务(HBPT)，在这项任务中，个体被要求估计每隔一段时间的心跳次数。比较两组间的准确度得分。控制年龄后，两组间HBPT差异有统计学意义((F-1，F-19)=7.78，p=.013，Cohen‘s d=1.16)。这些结果表明，从BN康复的个体中存在内感敏感性缺陷。因此，内感缺陷可能是弥合BN患者大脑功能障碍和症状表现之间差距的一个因素。(C)2013爱思唯尔有限公司。保留所有权利。
Self-report studies suggest that patients with bulimia nervosa (BN) evidence difficulties with interoceptive awareness. Indeed, interoceptive deficits may persist after recovery of BN and may be a biological trait that predisposes symptom development in BN. However, no studies to date have directly assessed interoceptive sensitivity, or accuracy in detecting and perceiving internal body cues, in patients with or recovered from BN. Nine women who had recovered from BN and 10 healthy control women completed the Heart Beat Perception Task (HBPT) in which individuals were required to estimate the number of heartbeats between intervals of time. Accuracy scores were compared between groups. Significant differences were found between the groups on the HBPT ((F-1,F-19) = 7.78, p = .013, Cohen's d = 1.16) when controlling for age. These results suggest that deficits in interoceptive sensitivity are present in individuals recovered from BN. Thus interoceptive deficits may be one factor that bridges the gap between brain dysfunction and symptom presentation in BN. (C) 2013 Elsevier Ltd. All rights reserved.
