睡眠质量和抑郁在童年不良经历青少年神经质人格与执行功能之间的链式中介作用

目的 探讨睡眠质量与抑郁在有童年不良经历(ACEs)的青少年神经质人格与执行功能间的中介作用,为提高该群体的执行功能提供参考。方法 2020年7—10月,运用心理相关评定量表对324名ACEs青少年的执行功能、抑郁、睡眠质量及神经质人格进行调查,采用Pearson相关分析分析各变量间关系,运用结构方程模型分析睡眠质量和抑郁在神经质与执行功能间的中介作用。结果 1)ACEs青少年的神经质人格、睡眠质量、抑郁总分及各维度和执行功能得分呈显著正相关关系(r=0.13~ 0.91,P<0.05)。2)神经质人格显著预测ACEs青少年执行功能(β=0.31,t=5.24,P<0.001);睡眠质量和抑郁分别在神经质与ACEs青少年执行功能间起中介作用,中介效应分别为20.3%、21.9%;同时,睡眠质量和抑郁在神经质与执行功能间起链式中介作用,中介效应为9.4%。结论 神经质人格可直接预测ACEs青少年执行功能,还可通过睡眠质量和抑郁的链式中介作用间接预测ACEs青少年的执行功能。

Chain mediating effects of sleep quality and depression on neurotic personality and executive function in adolescents with adverse childhood experiences

Objective To explore the mediating role of sleep quality and depression between neurotic personality and executive function in adolescents with adverse childhood experiences(ACEs),so as to provide reference for improving executive function of adolescents. Methods From July to October 2020,the executive function,depression,sleep quality and neuroticism of 324 adolescents with ACEs were investigated by psychological assessment scale. Pearson correlation analysis was used to analyze the relationship between the variables. Structural equation model was used to analyze the mediating role of sleep quality and depression between neuroticism and executive function. Results 1) The total score and each dimension scores of neuroticism,sleep quality,depression of adolescents with ACEs were positively correlated with executive function(r=0.13 - 0.91,P<0.05). 2) Neuroticism significantly predicted executive function of adolescents with ACEs(β=0.31,t=5.24,P<0.001). Sleep quality and depression played mediating roles between neuroticism and executive function of adolescents with ACEs,and mediation effects were 20.3% and 21.9%,respectively. Meanwhile,sleep quality and depression played a chain mediating role between neuroticism and executive function,with a mediation effect of 9.4%. Conclusions Neuroticism can not only directly predict the executive function of adolescents with ACEs,but also indirectly predict the executive function of adolescents with ACEs through the chain mediating effect of sleep quality and depression.
