The aim of this study was to explore the interpersonal-psychological theory of suicide (IPTS) in medical students. Higher levels of thwarted belongingness and perceived burdensomeness were expected in medical students with suicidality compared with medical students without suicidality, and a high level of acquired capability was expected in planners compared with ideators. Recruited for the study were 178 undergraduate medical students at the Université Libre de Bruxelles (ULB): 95 subjects without suicidality, 24 subjects with lifetime suicidality, 28 subjects with recent suicidal ideation, and 26 planners. An ad hoc questionnaire evaluated the risk of suicide as well as the "Suicidal thoughts and wishes" item of the BDI-II. The Interpersonal Needs Questionnaire (INS) measured thwarted belongingness (TB) and perceived burdensomeness (PB). The Acquired Capability for Suicide Scale (ACSS) measured notably fearlessness of death or pain tolerance and depression was rated using the revised version of the Beck Depression Inventory (BDI). Cognitive-affective symptoms of depression (CA-BDI) were assessed using six items of the BDI. Analyses of variance showed significant differences between groups for TB and PB but not for ACSS. Analyses of covariance, controlling for the CA-BDI scores, confirmed the significance of differences in TB and PB. Post hoc tests showed that (1) high levels of TB were characteristic of subjects with recent suicidal ideation and planners compared with subjects without suicidality; and (2) high levels of PB were characteristic of planners compared with the three other groups. Among the three characteristics of the IPTS, PB could be a strong predictor of severe suicide risk in medical students.
这项研究的目的是探索医学生的人际心理理论（IPTS）。与无自杀意念的医学生相比，有自杀意念的医学生的归属感受挫和被认为是负担的程度预计会更高，而与意向者相比，计划者的习得能力预计会更高。研究招募了布鲁塞尔自由大学（ULB）的 178 名本科医学生：95 名无自杀意念的受试者、24 名有终生自杀意念的受试者、28 名有近期自杀意念的受试者和 26 名计划者。一份专门的问卷评估了自杀风险以及 BDI-II 的“自杀想法和愿望”项目。人际需求问卷（INS）测量了归属感受挫（TB）和被认为是负担的程度（PB）。习得自杀能力量表（ACSS）主要衡量对死亡或疼痛的无畏和耐受力以及抑郁程度，使用贝克抑郁量表（BDI）的修订版进行评估。抑郁的认知-情感症状（CA-BDI）使用 BDI 的六个项目进行评估。方差分析显示，TB 和 PB 两组之间存在显著差异，但 ACSS 组之间无差异。协方差分析，控制 CA-BDI 评分，证实了 TB 和 PB 差异的显著性。事后检验显示，（1）与无自杀意念的受试者相比，近期有自杀意念和计划者的 TB 水平较高；（2）与其他三组相比，计划者的 PB 水平较高。在 IPTS 的三个特征中，PB 可能是医学生严重自杀风险的一个强有力的预测指标。
