People with eating disorders have elevated interoceptive deficits and risk for self-injurious behaviors (SIBs). Across two eating disorder samples, the relationship between interoceptive deficits (IDs) and SIBs was tested. Study 1 (n = 100) found that suicide attempters and those engaging in non-suicidal self-injury (NSSI) had greater IDs than those with no self-injury history. Lack of access to emotion regulation strategies accounted for the link between IDs and SIBs. In Study 2 (n = 92) multiple suicide attempters had greater IDs than single attempters and those engaging in NSSI; however, the latter two groups did not differ from one another. Interoceptive deficits may differentiate those who engage in severe SIBs from those who do not, and thus be a useful determinant of suicide risk severity among patients with eating disorders. Lack of access to emotion regulation strategies appears to be one pathway linking interoceptive deficits and self-injury.
患有饮食失调症的人存在较高的内感受缺陷和自残行为（SIBs）风险。本研究在两个饮食失调症样本中检验了内感受缺陷（IDs）与 SIBs 之间的关系。研究 1（n=100）发现，有自杀企图和非自杀性自伤（NSSI）的患者比没有自伤史的患者具有更大的 IDs。无法获得情绪调节策略解释了 IDs 与 SIBs 之间的联系。在研究 2（n=92）中，多个有自杀企图的患者比单次企图的患者和进行 NSSI 的患者具有更大的 IDs；然而，后两组彼此之间没有差异。内感受缺陷可能将那些从事严重 SIBs 的人与不从事的人区分开来，因此可能是饮食失调症患者自杀风险严重程度的一个有用决定因素。无法获得情绪调节策略似乎是内感受缺陷和自伤之间的一个联系途径。
