Suicidal ideation and behaviors constitute a serious public health issue both globally and in China, with nurses having a relatively higher suicide rate. While existing research has established that adverse childhood experiences (ACEs) may increase the risk of suicide-related behaviors, the precise mechanisms by which ACEs influence suicidal ideation remain underexplored, particularly among nurses. This research investigates the association between ACEs and suicidal ideation, while also analyzing the mediating effect of psychological strain and the moderating influence of impulsivity.
Two top public hospitals, one in Southern China and the other Eastern China, were selected to recruit young nurses for study. The sample consisted of 395 individuals with 80.76% being female and aged between 19 and 42 years. A self-reporting questionnaire survey was administered with a computerized program.
Psychological strain partially mediates the association between ACEs and suicide ideation, with the mediator effect representing 21.70% of the total effect. Impulsivity served as a moderator in the connection between ACEs and suicidal ideation.
This study discloses how ACEs can directly and indirectly influence nurses' suicidal ideation through psychological strain, and how impulsivity moderates the connection between ACEs and suicidal ideation. The research findings offer significant practical evidence for enhancing nurses' mental health levels. Future studies could focus on improving nurses' mental health by addressing factors like mitigating the impact of ACEs, reducing psychological strain, and managing impulsivity.
自杀观念和行为在全球及中国都是严重的公共卫生问题，护士的自杀率相对较高。虽然现有研究已证实童年不良经历（ACEs）可能增加自杀相关行为的风险，但ACEs影响自杀观念的确切机制仍未得到充分探索，尤其是在护士群体中。本研究调查ACEs与自杀观念之间的关联，同时分析心理压力的中介作用和冲动性的调节作用。
选取中国南方和东部的两家顶级公立医院，招募年轻护士进行研究。样本包括395名个体，其中80.76%为女性，年龄在19至42岁之间。采用计算机程序进行自填式问卷调查。
心理压力部分中介了ACEs与自杀观念之间的关联，中介效应占总效应的21.70%。冲动性在ACEs与自杀观念的联系中起调节作用。
本研究揭示了ACEs如何通过心理压力直接和间接影响护士的自杀观念，以及冲动性如何调节ACEs与自杀观念之间的联系。研究结果为提高护士心理健康水平提供了重要的实践依据。未来的研究可以聚焦于通过减轻ACEs的影响、减少心理压力和控制冲动性等因素来改善护士的心理健康。
