Inflammatory bowel diseases (IBD) are accompanied by symptoms that can vastly affect patients' representations of their bodies. The aim of this study was to investigate alterations in body evaluation and body ownership in IBD and their link to interoceptive sensibility, gastrointestinal-specific anxiety, and history of childhood maltreatment.
Body evaluation and ownership was assessed in 41 clinically remitted patients with IBD and 44 healthy controls (HC) using a topographical self-report method. Interoceptive sensibility, gastrointestinal-specific anxiety and a history of childhood maltreatment were assessed via self-report questionnaires.
Patients reporting higher interoceptive sensibility perceived their bodies in a more positive manner. Higher gastrointestinal-specific anxiety was linked to a more negative body evaluation particularly of the abdomen in patients with IBD. Childhood maltreatment severity strengthened the positive association between interoceptive sensibility and body ownership only in those patients reporting higher trauma load.
Altered body representations of areas associated with abdominal pain are linked to higher symptom-specific anxiety and lower levels of interoceptive sensibility in IBD. Particularly in patients with a history of childhood maltreatment, higher levels of interoceptive sensibility might have a beneficial effect on the patients' sense of body ownership.
炎症性肠病（IBD）伴有多种症状，这些症状会极大地影响患者对自身身体的认知。本研究旨在调查IBD患者身体评价和身体所有权的改变，以及它们与内感受敏感性、胃肠道特异性焦虑和童年期虐待史之间的联系。
采用一种地形学自我报告法，对41例临床缓解期的IBD患者和44名健康对照者（HC）进行身体评价和身体所有权评估。通过自我报告问卷对内感受敏感性、胃肠道特异性焦虑和童年期虐待史进行评估。
报告内感受敏感性较高的患者对自己身体的认知更为积极。较高的胃肠道特异性焦虑与IBD患者对身体尤其是腹部的更负面评价有关。童年期虐待的严重程度仅在那些报告创伤负荷较高的患者中加强了内感受敏感性与身体所有权之间的正相关。
IBD患者中，与腹痛相关区域的身体表征改变与较高的症状特异性焦虑和较低的内感受敏感性水平有关。特别是在有童年期虐待史的患者中，较高水平的内感受敏感性可能对患者的身体所有权感有有益影响。
