Abstract

Objective: Interoceptive deficits have been linked to suicidality and eating disorders. The relationship between disordered eating symptoms and suicidality may depend on the level of interoceptive deficits. It was expected that interoceptive deficits would moderate the relationship between disordered eating symptoms (oral control, dieting, and bulimia) and suicidality (suicide attempts, ideation, and communication) when interoceptive deficits were high. Methods: University students (N = 417, Mage = 19.75, 78.2% white, 72.4% female) completed self-report measures that assessed disordered eating, interoceptive deficits, and suicide history. Results: Interoceptive deficits emerged as a significant moderator only in the association between bulimia symptoms and suicidality, when interoceptive deficits were high. Conclusions: The results of this study indicate that bulimia symptoms may have a unique interaction with interoceptive deficits and suicidality. Future research should focus on targeting interoceptive deficits in treatment to help reduce disordered eating symptoms and suicide risk, particularly for students with bulimia symptoms.

摘要

目的：内感受缺陷与自杀和饮食失调有关。饮食失调症状与自杀之间的关系可能取决于内感受缺陷的水平。当内感受缺陷较高时，预计内感受缺陷将调节饮食失调症状（口腔控制、节食和暴食症）与自杀倾向（自杀企图、意念和沟通）之间的关系。方法：大学生（N = 417，M年龄 = 19.75，78.2% 白人，72.4% 女性）完成自我报告措施，评估饮食失调、内感受缺陷和自杀史。结果：只有当内感受缺陷较高时，内感受缺陷才成为贪食症症状与自杀之间关联的显着调节因素。结论：这项研究的结果表明贪食症症状可能与内感受缺陷和自杀有独特的相互作用。未来的研究应侧重于治疗中的内感受缺陷，以帮助减少饮食失调症状和自杀风险，特别是对于有贪食症症状的学生。
