The purpose of this study was to classify patients with suicidal tendencies into suicide attempts (SA), suicidal ideation (SI), and non-suicidal self-injury (NSSI) and to identify differences in temperaments and characters of the groups. It also aimed to identify difference between the groups and non-suicidal tendencies.
Using psychiatric diagnostic data of 195 patients, temperaments and characters were measured with the Temperament and Character Inventory, and the level of depression was measured with the Beck Depression Inventory. The subjects were classified into SA, SI, NSSI, psychiatric patients without suicidal tendencies (PP), and non-patient (Normal) groups, and multivariate analysis of variance and multinomial logistic regression were conducted.
The NSSI group had higher novelty seeking compared to the SI group, while having higher harm avoidance, lower persistence, and lower self-directedness compared to the SA group. Furthermore, low persistence was a better predictor for the SA group between SA and NSSI groups, and low novelty seeking was found to be a better predictor for the SI group between the SI and NSSI groups.
As a result, the group differences in temperaments and characters were found, which would be useful to identify patients with suicidal tendencies and provide appropriate interventions tailored to the temperaments and characters of each group.
本研究旨在将有自杀倾向的患者分为自杀未遂（SA）、自杀意念（SI）和非自杀性自伤（NSSI）三类，并确定这些组在气质和性格方面的差异。它还旨在找出这些组与非自杀倾向之间的差异。
利用195名患者的精神科诊断数据，使用气质与性格量表测量气质和性格，并用贝克抑郁量表测量抑郁程度。将受试者分为自杀未遂组、自杀意念组、非自杀性自伤组、无自杀倾向的精神科患者组（PP）和非患者（正常）组，并进行多变量方差分析和多项逻辑回归分析。
与自杀意念组相比，非自杀性自伤组的寻求新奇性更高，而与自杀未遂组相比，其回避伤害性更高、坚持性更低、自我导向性更低。此外，在自杀未遂组和非自杀性自伤组之间，低坚持性是自杀未遂组更好的预测指标，而在自杀意念组和非自杀性自伤组之间，低寻求新奇性被发现是自杀意念组更好的预测指标。
结果发现了气质和性格方面的组间差异，这将有助于识别有自杀倾向的患者，并根据每组的气质和性格提供适当的干预措施。
