ABSTRACT

This study aims to examine whether employees who perceive there to be social support from supervisors and colleagues would be better able to detach from work during non-work time and thus sleep better in times of high job demands. Considering contextual factors, such as type of employment (full- and part-time) and supervisor status (with and without), which could influence the associations between work, non-work, and sleep, we also explored these relationships within subgroups of employees. A total of 1856 employees participated in a two-wave-panel study representative of the German adult population. Controlling for the baseline level of sleep quality, regression analyses revealed that job demands predicted changes in sleep quality over a 6-month period and that detachment fully mediated this effect. Furthermore, perceived social support buffered the indirect effect of job demands on sleep quality via detachment. In summary, the results suggest that the interplay of job demands, detachment, and perceived social support is important in promoting sleep quality. Type of employment and supervisor status seem to be factors shaping the above-mentioned effects and should, therefore, be considered in future research.

摘要

本研究旨在检验认为从主管和同事那里得到社会支持的员工是否能够在非工作时间更好地脱离工作，从而在工作需求高的时候睡得更好。考虑到可能影响工作、非工作和睡眠之间关联的上下文因素，例如就业类型（全职和兼职）和主管状态（有和没有），我们还在员工亚组中探讨了这些关系. 共有 1856 名员工参加了一项代表德国成年人口的两波小组研究。控制睡眠质量的基线水平，回归分析显示，工作需求预测了 6 个月内睡眠质量的变化，而脱离完全调节了这种影响。此外，感知到的社会支持通过超脱缓冲了工作需求对睡眠质量的间接影响。总之，结果表明，工作需求、超脱和感知到的社会支持之间的相互作用对于提高睡眠质量很重要。就业类型和主管地位似乎是影响上述影响的因素，因此应在未来的研究中加以考虑。
