This study investigated the role of individual differences in neuroticism in conferring increased reactivity to the interpersonal antecedents for suicide proposed by the interpersonal theory of suicide.
Undergraduate students (N = 113) were screened and selected to form high (n = 58) and low (n = 55) neuroticism groups, and an experimental computer task was used to manipulate participants' experience of thwarted belongingness and perceived burdensomeness. Participants' self-reported desire to persist in the face of this induced interpersonal adversity was measured.
Results indicate that high neuroticism confers increased reactivity to the experimental induction of the interpersonal antecedents of suicidal ideation: Thwarted belongingness and perceived burdensomeness. Furthermore, this vulnerability corresponds to a diminished desire to persist with the task in the face of interpersonal adversity.
Neuroticism confers vulnerability for suicidal desire via an increased reactivity to the proximal, causal risk factors proposed by the interpersonal theory of suicide. This has implications for considering how personality risk factors such as neuroticism may interact with proximal interpersonal risk factors to increase suicidal ideation.
本研究旨在探讨神经质人格特质个体差异在增强对自杀的人际关系理论所提出的自杀人际前因的反应中的作用。
筛选并选择本科生（N=113）组成高神经质组（n=58）和低神经质组（n=55），并使用实验性计算机任务来操纵参与者的归属感受挫和感知负担感体验。测量参与者在面对这种人际逆境时坚持下去的自我报告愿望。
结果表明，高神经质人格特质会增强对自杀意念的人际前因的实验诱导的反应：归属感受挫和感知负担感。此外，这种脆弱性对应于在面对人际逆境时，坚持完成任务的愿望降低。
神经质人格特质通过对自杀的人际关系理论所提出的近端、因果风险因素的反应增强，从而导致自杀愿望的脆弱性。这对于考虑神经质等人格风险因素如何与近端人际风险因素相互作用从而增加自杀意念具有重要意义。
