Previous research shows that interoceptive deficits are associated with harmful behaviors such as nonsuicidal self-injury (NSSI), eating disorder pathology, and suicide attempts. The present study replicates and extends this area of research by examining the association between interoceptive deficits and suicidality in a military sample.
In Study 1, respondents to an online survey (N = 134) answered self-report questionnaires related to interoceptive deficits. Study 2 consisted of a secondary data analysis of 3,764 military service members who had previously completed questionnaires on interoceptive indicators, NSSI, suicide thoughts and attempts, and other psychopathology.
Study 1 demonstrated that our interoceptive deficits latent variable had adequate psychometric properties. In Study 2, multigroup confirmatory factor analysis showed that scores on the interoceptive deficits latent variable were highest among suicide attempters, lowest among those with no suicide history, and intermediary among participants who had thought about but not attempted suicide. The interoceptive deficits latent variable was more strongly related to NSSI and suicidality than were posttraumatic stress disorder symptoms, hopelessness, gender, and age.
These results confirm-and extend to a military sample-previous research showing that interoceptive deficits can provide important information about suicide risk.
先前的研究表明，内感受缺陷与非自杀性自我伤害（NSSI）、饮食障碍病理和自杀企图等有害行为有关。本研究通过在军事样本中检查内感受缺陷与自杀倾向之间的关系，复制和扩展了这一研究领域。
在研究 1 中，在线调查的受访者（N=134）回答了与内感受缺陷相关的自我报告问卷。研究 2 由对 3764 名曾完成过内感受指标、NSSI、自杀想法和尝试以及其他精神病理学问卷的军事人员的二次数据分析组成。
研究 1 表明，我们的内感受缺陷潜在变量具有足够的心理测量特性。在研究 2 中，多组验证性因子分析表明，内感受缺陷潜在变量的得分在自杀未遂者中最高，在无自杀史者中最低，在有自杀想法但未尝试自杀者中居中。内感受缺陷潜在变量与 NSSI 和自杀倾向的关系比创伤后应激障碍症状、绝望、性别和年龄更密切。
这些结果证实了-并扩展到军事样本-先前的研究表明，内感受缺陷可以提供有关自杀风险的重要信息。
