This study investigated interindividual differences in employees' trajectory of sleep quality over a 5-day workweek. We hypothesized that sleep quality is entrained to the rhythm of the workweek showing a linear increase from Monday to Friday. Moreover, we proposed that employees' chronic job demands (time pressure and social stress) and their negative work reflection on Sunday night moderated the sleep quality trajectory. In this study, 132 employees completed a baseline questionnaire assessing chronic job demands and age, and daily morning surveys from Monday to Friday assessing sleep quality and negative work reflection on Sunday. On average, sleep quality did not significantly change from Monday to Friday. However, negative work reflection moderated the sleep quality trajectory: When negative work reflection was high, the start level of sleep quality on Monday was lower and sleep quality displayed a linear increase over the workweek. When negative work reflection was low, employees' sleep quality remained stable throughout the week. Chronic social stress, but not time pressure, indirectly affected employees' sleep quality trajectory via negative work reflection on Sunday. Further, results revealed age differences in the effects of social stress on employees' sleep quality trajectory: The start level of sleep quality was lower and its increase over the workweek was stronger for older employees high on social stress. This study contributes to research on the dynamics of employee sleep and extends findings on age-differential effects of workplace characteristics.

工作要求和负面工作反映在员工整个工作周的睡眠质量轨迹中的作用。

这项研究调查了员工在5天工作周内睡眠质量轨迹的个体差异。我们假设睡眠质量与工作周的节奏有关，从星期一到星期五呈线性增长。此外，我们提出员工的长期工作需求（时间压力和社会压力）以及他们在周日晚上的负面工作反映可以改善睡眠质量的轨迹。在这项研究中，有132名员工完成了基线问卷，以评估长期工作需求和年龄，并在周一至周五每天进行早晨调查，以评估周日的睡眠质量和负面工作反映。平均而言，星期一至星期五的睡眠质量没有明显变化。但是，负向工作反射会降低睡眠质量的轨迹：当负向工作反射较高时，星期一的睡眠质量开始水平较低，并且睡眠质量在工作周内呈线性增加。当负面工作反映低时，员工的睡眠质量在整个星期中保持稳定。长期的社会压力而不是时间压力通过星期日的负面工作反映间接影响了员工的睡眠质量轨迹。此外，研究结果还显示出了在社交压力对员工睡眠质量轨迹的影响中的年龄差异：对于社交压力较高的老年员工，睡眠质量的开始水平较低，并且在整个工作周内睡眠质量的增长水平更高。这项研究有助于研究员工睡眠的动态，并扩展了关于工作场所特征的年龄差异影响的发现。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
