Bidirectional relations between work-related stress, sleep quality and perseverative cognition

Area of Science:

• Occupational Health Psychology
• Sleep Science
• Cognitive Psychology

Background:

• Work-related stress is a significant issue impacting employee well-being.
• Sleep quality is crucial for overall health and job performance.
• The interplay between stress, cognition, and sleep is not fully understood.

Purpose of the Study:

• To examine the bidirectional relationship between work-related stress and sleep quality.
• To investigate perseverative cognition as a potential mediator in this relationship.

Main Methods:

• Longitudinal two-wave study design.
• Online survey administered to 877 Dutch employees in 2012 and 2013.
• Structural equation modeling used for data analysis.

Main Results:

• Low sleep quality predicted increased work-related stress over time.
• Perseverative cognition showed bidirectional negative associations with sleep quality.
• Perseverative cognition demonstrated bidirectional positive associations with work-related stress.
• Perseverative cognition fully mediated the link between work-related stress and sleep quality.

Conclusions:

• Perseverative cognition is a key mechanism linking work-related stress and sleep quality.
• A vicious cycle exists where stress, cognition, and sleep mutually influence each other.
• Interventions targeting perseverative cognition may improve sleep and reduce stress.
