Nursing students face significant academic and emotional stress, which may increase the risk of suicidal ideation. This study examines the relationships between self-regulatory fatigue, experiential avoidance, and suicidal ideation, with a focus on the mediating role of experiential avoidance and the moderating role of negative life events.
We conducted a cross-sectional survey with 562 nursing students from a university in Heilongjiang, China. Data were collected using standardized scales: the General Information Questionnaire, Adolescent Suicidal Ideation Scale, Self-Regulatory Fatigue Scale, Acceptance and Action Questionnaire II, and Adolescent Self-Rating Life Events Checklist Scale.
The study revealed a significant total effect of self-regulatory fatigue on suicidal ideation (β = 0.5610, p < 0.001), accounting for 52.26% of the variance. Experiential avoidance partially mediated this relationship, with a significant indirect effect (β = 0.0723, 95% CI [0.0059, 0.1398]), representing 12.89% of the total effect. Self-regulatory fatigue strongly predicted experiential avoidance (β = 0.3567, p < 0.001), which in turn predicted suicidal ideation (β = 0.2028, p < 0.01). Negative life events moderated the first stage of the mediation pathway (self-regulatory fatigue → experiential avoidance), as evidenced by a significant interaction term (β = 0.1097, p = 0.0063). The moderated mediation model explained 57.92% of the variance in experiential avoidance.
Self-regulatory fatigue is significantly associated with suicidal ideation in nursing students, both directly and through the mediating role of experiential avoidance. Negative life events amplify this association. These findings highlight the importance of enhancing emotional regulation and coping strategies within nursing education to reduce the risk of suicidal ideation.
护理专业学生面临巨大的学业和情感压力，这可能会增加自杀意念的风险。本研究探讨自我调节疲劳、经验性回避与自杀意念之间的关系，重点关注经验性回避的中介作用以及负性生活事件的调节作用。
我们对来自中国黑龙江某大学的562名护理专业学生进行了横断面调查。使用标准化量表收集数据：一般信息问卷、青少年自杀意念量表、自我调节疲劳量表、接受与行动问卷II以及青少年自评生活事件清单量表。
研究揭示了自我调节疲劳对自杀意念有显著的总效应（β = 0.5610，p < 0.001），解释了52.26%的变异。经验性回避部分中介了这种关系，具有显著的间接效应（β = 0.0723，95% CI [0.0059, 0.1398]），占总效应的12.89%。自我调节疲劳强烈预测经验性回避（β = 0.3567，p < 0.001），而经验性回避又预测自杀意念（β = 0.2028，p < 0.01）。负性生活事件调节了中介路径的第一阶段（自我调节疲劳→经验性回避），显著的交互项证明了这一点（β = 0.1097，p = 0.0063）。调节中介模型解释了经验性回避中57.92%的变异。
自我调节疲劳与护理专业学生的自杀意念显著相关，既直接相关，也通过经验性回避的中介作用相关。负性生活事件加剧了这种关联。这些发现凸显了在护理教育中加强情绪调节和应对策略以降低自杀意念风险的重要性。
