Perceived burdensomeness (PB) and thwarted belongingness (TB) are important indicators of suicide risk; however, limited research has investigated applicability to military populations, and no efforts have been initiated to translate these constructs into easily implemented clinical tools. The current study examined the structure and validity of a brief self-report survey of PB and TB, the 10-item Interpersonal Needs Questionnaire (INQ-10), among a sample of 219 deployed military personnel. Factor analysis confirmed that PB and TB are distinct, and are correlated with psychiatric symptomatology. Receiver operating characteristic analyses indicated the most useful cutoff scores were PB=1 and TB=3.2. Both scales significantly improved the ability to rule-in and rule-out current suicide ideation among deployed service members.
感知负担（PB）和归属感受挫（TB）是自杀风险的重要指标；然而，针对军事人群的适用性研究有限，也尚未开展将这些概念转化为易于实施的临床工具的工作。本研究在 219 名部署军人样本中，检验了 PB 和 TB 的简短自我报告调查即 10 项人际需求问卷（INQ-10）的结构和有效性。因子分析证实 PB 和 TB 是不同的，并且与精神症状相关。受试者工作特征分析表明，最有用的截断值为 PB=1 和 TB=3.2。这两个量表都显著提高了对现役军人当前自杀意念的确诊和排除能力。
