ABSTRACT

The Interpersonal Theory of Suicide posits that two unmet interpersonal needs, thwarted belongingness and perceived burdensomeness, interact to predict suicide desire. These two constructs are frequently assessed using the 15-item Interpersonal Needs Questionnaire (INQ-15); however, this measure has never been validated in military service members. The current study analyzed the psychometric properties of the INQ-15 in a sample of (N = 1096) military personnel stationed overseas. Results indicated that the two-factor model of the INQ-15 had a poor model fit in this population; however, a bifactor model with two specific factors representing TB and PB demonstrated good fit. As seen in previous research, perceived burdensomeness was more strongly related to suicidal ideation severity than thwarted belongingness. Implications and future directions for research are discussed.

 抽象的

自杀的人际理论认为，两种未满足的人际需求，即受挫的归属感和感知到的负担，相互作用，预测自杀欲望。这两种结构经常使用包含 15 项的人际需求问卷 (INQ-15) 进行评估；然而，这项措施从未在军人中得到验证。当前的研究分析了驻海外军事人员样本（ N = 1096）中 INQ-15 的心理测量特性。结果表明，INQ-15 的双因素模型对该人群的模型拟合较差；然而，具有代表 TB 和 PB 的两个特定因素的双因素模型表现出良好的拟合度。正如之前的研究所示，与受挫的归属感相比，感知到的负担与自杀意念的严重程度关系更为密切。讨论了研究的意义和未来方向。
