摘要
目的:探讨睡眠质量和脑力疲劳之间的关系以及对二者关系可能有影响的自我情绪管理的中介效应和调节效应。方法:应用匹茨堡睡眠质量指数量表、多维疲劳量表和自我情绪管理问卷对521例医务人员进行测评,利用回归分析来研究变量之间的效应关系。结果:睡眠质量和脑力疲劳的相关系数为0.380(P<0.001)。睡眠质量对脑力疲劳的影响中,19.13%是通过中介变量自我情绪管理间接影响的。交互作用项"睡眠质量×自我情绪管理"的偏回归系数差异有统计学意义(B=0.035,t=2.875,P=0.004),且引入交互项后ΔR2差异亦有统计学意义(ΔR2=0.196,P<0.001)。结论:自我情绪管理在医务人员的睡眠质量和脑力疲劳的关系中起中介效应和调节效应。
Aim:To investigate the relationship between sleep quality and mental fatigue by adding “third variable”, named, mediator and moderator .Methods:A total of 521 medical staff were investigated by Pittsburgh sleep quality in-dex, the multidimensional fatigue inventory-20, and emotional intelligence scale .The hierarchical regression was used to explore the mediating effect and moderating effect .Results:The correlation coefficient of sleep quality and mental fatigue was 0.380(P&lt;0.001).The self emotional management played an incomplete intermediary role in the effect of the sleep&amp;nbsp;quality on the mental fatigue , with the mediating effect accounting for 19 .13%of the total effects .There was statistic sig-nificance in the interaction variable (sleep quality &#215;self emotional management) of regression coefficient (B=0.035,t=2.875,P=0.004) and R2 change (ΔR2 =0.196, P&lt;0.001).Conclusion: The self emotional management may play both an incomplete intermediary role and a modulatory role on the relationship of sleep quality and mental fatigue .
