Alterations in the perception of body signals (i.e., interoceptive awareness [IA]) are considered crucial for the development and maintenance of somatoform disorders (SFDs). However, competing theories come to different conclusions about whether IA is increased or decreased in SFDs. The present study investigated IA in 23 patients with SFDs (as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) and in 27 healthy controls. IA was reliably assessed with two well-established heartbeat perception paradigms (heartbeat discrimination task and mental tracking task). The results of both paradigms showed no evidence for increased IA in patients with SFDs. Correlational analyses revealed that having a higher number of somatoform symptoms was significantly linked to lower (rather than higher) IA in SFDs. These findings are in line with recent cognitive approaches to SFDs that stress the importance of biased schema-guided processing of interoceptive information.
躯体形式障碍患者的躯体信号感知（即内感受意识[IA]）发生改变，这被认为对躯体形式障碍的发展和维持至关重要。然而，不同理论对于躯体形式障碍患者的 IA 是增加还是减少存在不同结论。本研究使用两种成熟的心跳感知范式（心跳辨别任务和心理追踪任务）对 23 名躯体形式障碍患者（根据《精神障碍诊断与统计手册（第四版）》定义）和 27 名健康对照者进行了 IA 可靠评估。这两种范式的结果均未显示躯体形式障碍患者的 IA 增加。相关分析表明，躯体形式障碍患者的躯体症状越多，IA 越低（而不是越高）。这些发现与最近的躯体形式障碍认知方法一致，该方法强调了内感受信息的有偏差的模式引导加工的重要性。
