People with eating disorders (ED) have elevated rates of suicidal thoughts and behaviors. We used network analysis to identify symptoms that bridge EDs and suicidality, as well as central symptoms within the network, among 3 groups of adults. Participants were either (a) clinical psychiatric outpatients without current EDs (n = 538), (b) clinical psychiatric outpatients with a lifetime suicide attempt (n = 166), or (c) people with current EDs (n = 238). Networks were jointly estimated among groups. Within the Suicide Attempt and ED groups, interoceptive deficits and pain tolerance emerged as important bridge symptoms, whereas feeling inadequate was an important bridge symptom in the Clinical Outpatient group. Within all groups, having thoughts of killing oneself and feeling inadequate were central, meaning that they were most strongly connected to all other symptoms in the networks. Further, results indicate that a similar problem-interoceptive impairment-may link ED symptoms and suicidality both within people with EDs and people with suicide attempts. Overall, these findings are consistent with the notion that EDs and suicidality may bidirectionally influence one another, possibly through shared mechanisms (e.g., interoceptive impairment) or direct pathways (e.g., suicidal ideation being strongly connected to ED symptoms), though prospective work is needed to test these possibilities.

识别三个样本中饮食失调症状与自杀意念之间的桥梁途径。

饮食失调症（ED）的自杀念头和行为发生率较高。我们使用网络分析来确定在3组成年人中桥接ED和自杀的症状以及网络中的中心症状。参加者是（a）没有当前急诊就诊的临床精神科门诊患者（n = 538），（b）有终身自杀未遂的临床精神科门诊患者（n = 166）或（c）有当前EDs的人（n = 238）。网络是在群体之间共同估算的。在自杀未遂组和急诊室组中，感觉障碍和疼痛耐受性已成为重要的桥梁症状，而感觉不足是临床门诊组的重要桥梁症状。在所有群体中，自杀和感到不足的想法很重要，意味着它们与网络中的所有其他症状之间的联系最为紧密。此外，结果表明，在患有ED的人和有自杀企图的人中，相似的问题-感知障碍-可能将ED症状和自杀性联系起来。总体而言，这些发现与以下观点一致：尽管需要开展前瞻性工作，但EDs和自杀性可能会通过共享机制（例如，感受性障碍）或直接途径（例如，自杀意念与ED症状密切相关）而双向影响。测试这些可能性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。结果表明，类似的问题-感知障碍-可能将ED征状和自杀未遂者的ED症状和自杀性联系起来。总体而言，这些发现与以下观点一致：尽管需要开展前瞻性工作，但EDs和自杀性可能会通过共享机制（例如，感受性障碍）或直接途径（例如，自杀意念与ED症状密切相关）而双向影响。测试这些可能性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。结果表明，类似的问题-感知障碍-可能将ED征状和自杀未遂者的ED症状和自杀性联系起来。总体而言，这些发现与以下观点一致：尽管需要开展前瞻性工作，但EDs和自杀性可能会通过共享机制（例如，感受性障碍）或直接途径（例如，自杀意念与ED症状密切相关）而双向影响。测试这些可能性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。尽管需要前瞻性的工作来测试这些可能性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。尽管需要前瞻性的工作来测试这些可能性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
