Previous research has demonstrated that both suicidal ideation (SI) and eating disorders (EDs) are associated with poor interoceptive awareness (IA). Suicidality research has demonstrated that the IA dimension of lower body trust is associated with SI, suicide plans, and suicide attempts. Similarly, in ED samples, recent research supports that low body trust has been the most robust dimension of IA associated with eating pathology. However, to date, research is lacking in how dimensions of IA may be associated with SI in an ED sample, above and beyond the impact of eating pathology on SI. Thus, in a clinical ED sample, the present study sought to determine which IA dimensions predict the presence and severity of SI, above and beyond ED symptoms. Participants (N = 102) completed a clinical interview assessing SI and self-report assessments including the Multidimensional Assessment of Interoceptive Awareness (MAIA). Results demonstrated that patients with current SI reported greater ED psychopathology, lower MAIA Attention Regulation, MAIA Self-Regulation, and MAIA Trusting scores compared to patients without SI. Higher ED psychopathology and lower MAIA Attention Regulation, Self-Regulation, and Trusting subscale scores were all significantly associated with the presence of SI. However, only low MAIA Trusting scores predicted the presence of SI, above and beyond covariates (age, depression, and eating pathology). No MAIA subscales were correlated with the severity of SI. Consistent with previous research, results suggest low MAIA Trusting scores may be associated with SI in ED samples and highlight the need for future research on mechanisms of these associations.
先前的研究表明，自杀意念（SI）和饮食障碍（EDs）都与较差的内感受意识（IA）有关。自杀研究表明，下半身信任的 IA 维度与 SI、自杀计划和自杀企图有关。同样，在 ED 样本中，最近的研究支持低身体信任是与饮食病理学相关的最稳健的 IA 维度。然而，迄今为止，关于 IA 的维度如何与 ED 样本中的 SI 相关，而不仅仅是饮食病理学对 SI 的影响，研究还很缺乏。因此，在临床 ED 样本中，本研究旨在确定 IA 的哪些维度可以预测 SI 的存在和严重程度，而不仅仅是 ED 症状。参与者（N=102）完成了一项临床访谈，评估 SI 和自我报告评估，包括多维内感受意识评估（MAIA）。结果表明，目前有 SI 的患者报告的 ED 心理病理学更严重，MAIA 注意调节、MAIA 自我调节和 MAIA 信任得分较低，与没有 SI 的患者相比。更高的 ED 心理病理学和更低的 MAIA 注意调节、自我调节和信任子量表得分与 SI 的存在显著相关。然而，只有低 MAIA 信任得分可以预测 SI 的存在，而与协变量（年龄、抑郁和饮食病理学）无关。没有 MAIA 子量表与 SI 的严重程度相关。与先前的研究一致，结果表明，低 MAIA 信任得分可能与 ED 样本中的 SI 有关，并强调需要进一步研究这些关联的机制。
