Uncovering energetic mechanisms that link work stressors to sleep
本研究基于努力恢复模型，通过98位在职单亲母亲的每日日记数据，分析挑战型和阻碍型工作压力源如何通过身体疲劳、心理疲劳和活力影响睡眠，发现个体间差异支持了间接效应。
In this study we examine whether and why daily work stressors are associated with sleep quality and sleep quantity. We draw on the effort-recovery model to test daily relationships between challenge and hindrance work stressors and sleep through physical and psychological fatigue, and vigor. We analyze daily diary data from 98 working sole mothers collected over seven days. The within-person daily hypotheses linking challenge and hindrance stressors to sleep via energetic mediators in our model were not supported. Exploratory analysis revealed several of our hypotheses were supported at the between-person level. Challenge and hindrance stressors were differentially related to psychological fatigue and physical fatigue such that hindrance stressors were positively associated, and challenge stressors were negatively associated. Challenge and hindrance stressors were differentially related to vigor such that hindrance stressors were negatively associated, and challenge stressors were positively associated. Across individuals, challenge and hindrance stressors were indirectly related to sleep quantity through these energetic mediators. This study answers calls for more investigations into mechanisms linking work stressors and sleep, and emphasises the importance of examining phenomena at multiple levels of analysis. Theoretical and practical implications for the challenge-hindrance framework and effort-recovery model, including the appropriate timeframe for study, are discussed.
