目的我们的研究旨在验证新开发的德国自杀能力问卷（GCSQ）。它应该评估对死亡的无畏精神和疼痛耐受力，这两个方面都是自杀人际理论所假设的获得性自杀能力的两个方面。方法这项横断面研究是针对两个临床样本（n = 424）和一个在线样本（n = 532）进行的。研究了因素结构、收敛和判别效度、预测效度以及重测信度。结果得出两个因素——“死亡恐惧”和“疼痛耐受性”。其中一项“感知能力”项目评估受试者对所获得能力的自我感知。子量表和“感知能力”项目都表现出良好的结构效度和高重测信度。对死亡的无畏被证明可以预测自杀行为的发生，而疼痛耐受性对自杀行为的重要性尚未得到证实。受试者对其自身能力的感知对于企图状态和自杀行为都具有很高的预测价值。结论GCSQ 似乎是衡量疼痛耐受性、对死亡的无畏性和对获得的自杀能力的自我感知的有用指标。
ObjectiveOur study aimed at the validation of the newly developed German Capability for Suicide Questionnaire, the GCSQ. It is supposed to assess both fearlessness of death and pain tolerance, both facets of the acquired capability to commit suicide as postulated by the interpersonal theory of suicide.MethodsThis cross-sectional study was conducted on two clinical (n= 424) and an online sample (n= 532). Factor structure, convergent and discriminant validity, predictive validity as well as test–retest reliability were investigated.ResultsTwo factors—“Fearlessness of Death” and “Pain Tolerance”—were derived. One item, the “perceived capability” item, assesses the subject's self-perception of acquired capability. Both subscales and the “perceived capability”-item demonstrate good construct validity and a high test–retest reliability. Fearlessness of death proves to be predictive for the occurrence of suicidal behaviors, whereas the importance of pain tolerance for suicidal behaviors was not confirmed. The subject's perception of his own capability is of high predictive value for both attempt status and suicidal behaviors.ConclusionThe GCSQ seems to be a useful measure of pain tolerance, fearlessness of death and the self-perception of acquired capability of suicide.
