Suicide is a global public health concern, significantly affecting young adults across the world. Studies have shown that nursing students exhibit a higher propensity for suicidal ideation in comparison to students from other academic disciplines. Personality traits have been recognized as a significant and comparatively consistent risk factor for suicidal ideation. However, the specific pathways through which personality traits influence suicidal ideation are not yet fully understood. Based on the Interpersonal-Psychological Theory of Suicide, this study aimed to examine the serial mediation effects of depressive symptoms, thwarted belongingness, and perceived burdensomeness in the relationship between the Big Five personality traits and suicidal ideation among nursing students.
A descriptive cross-sectional survey was conducted. A sample of 435 nursing students participated in the online survey. Participants completed Chinese versions of questionnaires of the Suicidal Behaviors Questionnaire-Revised, Big Five Personality Inventory-15, Patient Health Questionnaire-9, and Interpersonal Needs Questionnaire. SPSS version 27.0 and the PROCESS 4.3 macro model 6 were used for statistical analyses.
The prevalence of suicidal ideation among nursing students was 17.5%. Neuroticism (β = 0.26, p < .001), conscientiousness (β = -0.10, p = .001), agreeableness (β = -0.14, p < .001), openness (β = -0.11, p < .001), and extraversion (β = -0.19, p < .001) had a statistically significant total effect on suicidal ideation. Furthermore, significant indirect effects were found between Big Five personality traits and suicidal ideation, serially mediated by depressive symptoms, thwarted belongingness, and perceived burdensomeness.
The findings indicate that nursing students exhibit high levels of suicidal ideation, which are influenced by their Big Five personality traits. This relationship appears to be serially mediated by depressive symptoms, thwarted belongingness, and perceived burdensomeness, aligning with the Interpersonal-Psychological Theory of Suicide. Therefore, interventions focused on reducing depressive symptoms in nursing students with vulnerable personality traits may help mitigate feelings of thwarted belongingness and perceived burdensomeness, ultimately reducing suicidal ideation.
自杀是一个全球公共卫生问题，对世界各地的年轻人产生重大影响。研究表明，与其他学科的学生相比，护理专业学生有更高的自杀意念倾向。人格特质已被认为是自杀意念的一个重要且相对一致的风险因素。然而，人格特质影响自杀意念的具体途径尚未完全明确。基于自杀的人际心理理论，本研究旨在探讨抑郁症状、归属感受挫和感知负担在护理专业学生大五人格特质与自杀意念关系中的系列中介作用。
进行了一项描述性横断面调查。435名护理专业学生参与了在线调查。参与者完成了中文版的《自杀行为问卷修订版》《大五人格量表-15》《患者健康问卷-9》和《人际需求问卷》。使用SPSS 27.0版和PROCESS 4.3宏程序模型6进行统计分析。
护理专业学生自杀意念的发生率为17.5%。神经质（β = 0.26，p <.001）、尽责性（β = -0.10，p =.001）、宜人性（β = -0.14，p <.001）、开放性（β = -0.11，p <.001）和外向性（β = -0.19，p <.001）对自杀意念有统计学上的显著总效应。此外，在大五人格特质与自杀意念之间发现了显著的间接效应，由抑郁症状、归属感受挫和感知负担进行系列中介。
研究结果表明，护理专业学生表现出较高水平的自杀意念，这受到他们的大五人格特质的影响。这种关系似乎由抑郁症状、归属感受挫和感知负担进行系列中介，这与自杀的人际心理理论一致。因此，针对具有易损人格特质的护理专业学生，专注于减轻抑郁症状的干预措施可能有助于减轻归属感受挫和感知负担的感觉，最终减少自杀意念。
