Research has demonstrated an inconsistent relationship between suicide ideation and personality traits. This is the first study to empirically examine the relationship of the Five Factor Model of personality with current, past and no suicide ideation, and with the two interpersonal risk factors of suicide: thwarted belongingness and perceived burdensomeness (Joiner, T., 2005. Why people die by suicide. Cambridge, MA, US: Harvard University Press). Results indicate that high neuroticism was associated with both current ideation and a history of suicide ideation and extraversion was associated with current ideation. Neuroticism was positively related to thwarted belongingness and perceived burdensomeness, while extraversion was negatively related to these interpersonal predictors of suicide. Agreeableness was negatively related to thwarted belongingness but not perceived burdensomeness, indicating differentiated patterns of relationships between this personality domain and the two suicide constructs. Furthermore, these personality domains predicted 23.82% of variance for thwarted belongingness and 15.07% of the variance for perceived burdensomeness, above and beyond demographic variables associated with suicide ideation. This study, which was conducted with a college sample, demonstrates the potential benefit of identifying predispositional risk factors for suicide ideation and interpersonal predictors of suicide. This may have implications for the development of upstream preventative measures against suicide.
研究表明自杀意念与人格特质之间的关系并不一致。这是第一项实证研究，旨在检验人格的五因素模型与当前、过去和无自杀意念的关系，以及与自杀的两个人际风险因素：归属感受挫和负担感（Joiner，T.，2005. 人们为何自杀. 马萨诸塞州剑桥，美国：哈佛大学出版社）。结果表明，高神经质与当前意念和自杀意念史有关，外向性与当前意念有关。神经质与归属感受挫和负担感呈正相关，而外向性与这些自杀的人际预测因素呈负相关。宜人性与归属感受挫呈负相关，但与负担感无关，表明这一人格领域与自杀的两个结构之间存在不同的关系模式。此外，这些人格领域在预测归属感受挫的 23.82%的方差和感知负担的 15.07%的方差方面，超过了与自杀意念相关的人口统计学变量。这项在大学生样本中进行的研究表明，识别自杀意念的倾向风险因素和自杀的人际预测因素具有潜在的益处。这可能对制定针对自杀的上游预防措施具有重要意义。
