Abstrakt: Objective: This study investigates the mediating role of rumination in the relationship between work-related stress and sleep quality. Sleep quality is a critical component of mental health and wellbeing. Work-related stress is a potential risk factor for poor sleep quality, and this research focuses on how the constructs of rumination—affective rumination, detachment, and problem-solving rumination—may mediate this association. Methods: Data from the Dresden Burnout Study were analyzed cross-sectionally and longitudinally over three timepoints. The sample included 360 full- and parttime employees. Work-related stress was assessed using the effort–reward Imbalance Questionnaire, sleep quality using the Pittsburgh Sleep Quality Index, and rumination using the Work-Related Rumination Questionnaire. Results: The study found that work-related stress was positively correlated with reduced sleep quality, both cross-sectionally and longitudinally. In addition, work-related stress predicted increased levels of affective rumination and detachment but not of problem-solving rumination. Affective rumination and detachment partially mediated the relationship between work-related stress and sleep quality, suggesting that individuals who experience higher levels of work-related stress are more likely to engage in ruminative thoughts about their work experiences, which, in turn, leads to reduced sleep quality. Conclusion: These findings highlight the importance of considering cognitive processes such as rumination when addressing sleep disturbance related to work stress. Future research should include objective measures of sleep quality and consider shorter intervals to capture immediate changes in stress and sleep patterns. By addressing these factors, healthcare professionals can better support those suffering from sleep disturbance due to work-related stress. Ultimately, this may have a positive impact on their overall wellbeing and productivity at work.
