Abstract

Suicide is a serious public health problem and is the fourth leading cause of death among adolescents. Suicide ideation is the most significant predictor of suicide. However, few empirical studies have examined the relationship between stressful life events, insomnia, depression symptoms, self‐esteem, and suicide ideation among college students. This study builds on O'Connor's The integrated motivational‐volitional model of suicidal behavior theory will verify the relationship between these five factors through a large data study among college students, and further reveal the mechanisms and interventions of suicide ideation among college students. A total of 2717 (mean age = 19.81 years, 22.49% male) college students from South China participated in this behavioral and health survey. Using self‐reported questionnaires which were Adolescent Self Rating Life Events Check‐list, MINI‐C, Insomnia Severity Index, PHQ‐9, and Self‐Esteem Scale to assess the subjects’ demographic information, suicide ideation, stressful life events, insomnia, depressive symptoms, and self‐esteem levels as comprehensively as possible. A moderated chain mediation model was used to validate their relationship. The results showed that stressful life events significant positively predicted insomnia symptoms, depressive symptoms, and suicide ideation. The mediating effect of depression between stressful life events and suicide ideation was significant. The chain mediating effect of insomnia and depression between stressful life events and suicide ideation was significant. However, the mediating effect of insomnia between stressful life events and suicide ideation was not significant. Also, the positive prediction of stressful life events and depression on suicide ideation was weaker when the individual's self‐esteem level was higher, and the moderated chain mediating effect was significant. This study developed a moderated chain mediation model, and proposes a new integrated stress coping‐self‐perception model of suicide ideation to discover the important role of self‐esteem levels in adolescent suicide prevention.
大学生的生活压力事件:与失眠、抑郁、自尊和自杀意念的直接和间接关系
自杀是一个严重的公共健康问题,也是导致青少年死亡的第四大原因。自杀意念是预测自杀的最重要因素。然而,很少有实证研究对大学生的生活压力事件、失眠、抑郁症状、自尊和自杀意念之间的关系进行研究。本研究将以奥康纳的自杀行为动机-波动综合模型理论为基础,通过对大学生的大数据研究,验证这五个因素之间的关系,并进一步揭示大学生自杀意念的产生机制和干预措施。华南地区共有 2717 名大学生(平均年龄为 19.81 岁,男性占 22.49%)参与了此次行为与健康调查。调查采用自我报告式问卷,即青少年生活事件自评量表(Adolescent Self Rating Life Events Check-list)、MINI-C、失眠严重程度指数(Insomnia Severity Index)、PHQ-9和自尊量表(Self-Esteem Scale),尽可能全面地评估受试者的人口统计学信息、自杀意念、生活压力事件、失眠、抑郁症状和自尊水平。研究采用调节链中介模型来验证它们之间的关系。结果显示,生活压力事件对失眠症状、抑郁症状和自杀意念有显著的正向预测作用。抑郁症在生活压力事件和自杀意念之间的中介效应显著。失眠和抑郁在生活压力事件和自杀意念之间的连锁中介效应是显著的。然而,失眠在生活压力事件和自杀意念之间的中介效应不明显。此外,当个体的自尊水平较高时,生活压力事件和抑郁对自杀意念的正向预测作用较弱,且调节链中介效应显著。本研究建立了一个调节链中介模型,并提出了一个新的压力应对-自我认知综合自杀意念模型,以发现自尊水平在青少年自杀预防中的重要作用。
