Spillover Effect of Job Stress on Life Satisfaction： a Diary Study

目的：基于挑战型-阻碍型压力源模型与工作要求-资源理论,探索工作压力对生活领域的溢出效应机制及心理脱离的调节作用。方法：通过对55名白领职员连续5天的线上日记调查获得226个有效数据点（occasions）。结果：多层线性模型分析发现,挑战型压力源通过提高活力水平对生活满意度产生积极溢出效应,阻碍型压力源通过削弱活力水平对生活满意度产生消极溢出效应;尽管两类压力源都会显著增加情绪耗竭水平,但是情绪耗竭对生活满意度没有显著消极溢出效应。心理脱离水平可以增强活力对生活满意度的溢出效应。 Objective： Based on the Challenge-Hindrance stressors Model and Job Demand-Resource theory, the current study aimed to explore spillover effect of job stressors on life satisfaction, as well as the possible moderating role of psychological detachment. Methods： A total of 55 white-collar employees were recruited to participate in a 5 consecutive days＇ online daily survey, and 226 valid occasions were collected. Results： Hierarchical linear model analysis showed that challenge stressors had a positive spillover effect on life satisfaction via vigor, whereas hindrance stressors had a negative spillover effect on life satisfaction via vigor; Notwithstanding two categories of stressors both significantly increased exhaustion, the spillover effect of exhaustion on life satisfaction was not significant. In addition, psychological detachment can boost the spillover effects of vigor on life satisfaction.
