In the interpersonal theory of suicide, perceived burdensomeness (PB) and thwarted belongingness (TB) are proximal triggers of suicidal ideation. Using the 15-item version of the Interpersonal Needs Questionnaire (INQ-15), suicidal ideation in psychiatric inpatients was predicted by the PB and TB scales, and cut-off scores were recommended. In this study, women (N = 942) who reported one or more chronic, invisible illnesses completed an online survey including the INQ-15 and the Suicide Behaviours Questionnaire-Revised (SBQ-R). PB and TB correlated significantly with SBQ-R total scores (r = 0.575 and 0.437, respectively; p < 0.01). In a Receiver Operating Characteristic analysis, scores of 17 for PB and 37 for TB maximized the correct classification of high-risk and low-risk participants, with slightly higher classification accuracy for PB than TB (AUCs = 0.781 and 0.701, respectively). These results support the INQ-15 scales in screening for suicidal ideation among chronically ill women.
在人际理论的自杀中，可察觉到的累赘感（PB）和受挫的归属感（TB）是自杀意念的直接诱因。使用 15 项人际需求问卷（INQ-15），精神病住院患者的自杀意念可以由 PB 和 TB 量表预测，并推荐了截断分数。在这项研究中，报告有一个或多个慢性、无形疾病的女性（N=942）完成了一项在线调查，包括 INQ-15 和修订后的自杀行为问卷（SBQ-R）。PB 和 TB 与 SBQ-R 总分显著相关（r=0.575 和 0.437，分别；p<0.01）。在受试者工作特征分析中，PB 得分为 17，TB 得分为 37，可最大化高风险和低风险参与者的正确分类，PB 的分类准确性略高于 TB（AUCs=0.781 和 0.701，分别）。这些结果支持 INQ-15 量表筛查慢性疾病女性的自杀意念。
