日常负性生活事件、感知压力与情绪个体内可变性的关系——基于经验取样法的研究

The Relationship Between Daily Negative Life Events,Perceived Stress and Intraindividual Variability of Affect——Research on Empirical Sampling Method

目的:探讨日常负性生活事件与情绪个体内可变性(情绪变迁、情绪自旋与情绪脉冲)的关系,以及日常感知压力在两者间的多水平中介效应。方法:对144名被试当下正发生或感受到的负性生活事件、感知压力和核心情绪状态进行持续14天、每天3次的动态跟踪测量。结果:多层结构方程模型表明负性生活事件对效价变异性、激活变异性、情绪自旋和情绪脉冲具有正向预测。感知压力在负性生活事件对效价变异性、情绪自旋和情绪脉冲的影响中具有中介效应。结论:个体日常经历的负性生活事件通过其内在感知到的压力程度,进而导致个体在情绪效价维度上产生变化,同时引起核心情绪状态的不稳定和情绪强度波动。

Objective:To explore the relationship between daily negative life events and intraindividual variability of affect(affect flux,affect spin and affect pulse),and the multi-level mediating effect of daily perceived stress between them.Methods:144 subjects were dynamically followed up three times a day for 14 days.Results:The analysis of multi-layer structural equation model showed that negative life events had a positive predictive effect on titer variability,activation variability,affect spin and affect pulse.Perceived stress mediated the effects of negative life events on titer variability,affect spin and affect pulse.Conclusion:The negative life events experienced by individuals lead to changes in the dimension of emotional potency through their internal perceived stress,accompanied by the instability of core emotional state and strong fluctuation of emotional intensity.
