Abstract

Background

The prevalence of suicide is high among major depressive adolescents. Poor sleep quality has been documented as a significant risk factor for suicide, influencing perceived social support. Enhanced social support acts as a buffer against suicidal ideation and positively impacts resilience, reducing the prevalence of suicidal ideation. This reciprocal relationship between sleep quality, social support and resilience forms the basis for understanding the mechanisms contributing to suicidal ideation in major depressive adolescents.

Methods

A total of 585 major depressive adolescents aged 11 to 24 years was conducted to explore these associations. Assessments included the Pittsburgh Sleep Quality Index, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale and Beck Scale for Suicide Ideation. Pearson correlation and Model 6 in the SPSS program were employed for chain mediating tests.

Results

Better sleep quality positively predicted decreased suicide ideation (β = 0.207, p < 0.01) and predicted lower perceived social support (β = −0.226, p < 0.01) and resilience (β = −0.355, p < 0.01). Perceived social support positively predicted increased resilience (β = 0.422, p < 0.01) and negatively predicted suicide ideation (β = −0.288, p < 0.01). Resilience negatively predicted suicide ideation (β = −0.187, p < 0.01). Sleep quality indirectly predicted suicide ideation through perceived social support and resilience, with a mediation value of 0.0678 (95% CI [0.0359, 0.1060]), constituting 10.65% of the total effect.

Conclusions

This study establishes that sleep quality indirectly predicts suicide ideation in major depressive adolescents, mediated independently by perceived social support and resilience.

青少年抑郁症患者的睡眠质量与自杀意念：感知到的社会支持和复原力的连锁中介效应

背景重度抑郁青少年的自杀率很高。据记载，睡眠质量差是导致自杀的一个重要风险因素，会影响感知到的社会支持。加强社会支持可以缓冲自杀意念，并对恢复能力产生积极影响，从而降低自杀意念的发生率。睡眠质量、社会支持和复原力之间的这种相互关系是了解导致重度抑郁青少年产生自杀意念的机制的基础。方法研究人员对 585 名年龄在 11-24 岁之间的重度抑郁青少年进行了调查，以探究这些关联。评估包括匹兹堡睡眠质量指数、感知社会支持多维量表、康纳-戴维森复原力量表和贝克自杀意念量表。采用皮尔逊相关性和 SPSS 程序中的模型 6 进行连锁中介测试。结果睡眠质量越好，自杀念头越少（β = 0.207，p < 0.01），感知到的社会支持越低（β = -0.226，p < 0.01），复原力越低（β = -0.355，p < 0.01）。感知到的社会支持正向预测复原力的增强（β = 0.422，p < 0.01），负向预测自杀意念（β = -0.288，p < 0.01）。复原力对自杀意念有负向预测作用（β = -0.187，p < 0.01）。睡眠质量通过感知的社会支持和复原力间接预测自杀意念，中介值为 0.0678 (95% CI [0.0359, 0.1060])，占总效应的 10.65%。结论本研究证实，睡眠质量可间接预测重度抑郁青少年的自杀意念，并通过感知到的社会支持和抗逆力进行独立中介。
