The relationship between work requirements and mental distress in hospital staff: the chain mediating effects of rumination and work recovery classes

The findings revealed three distinct WR classes among hospital staff. Significant associations were found between work requirements and mental distress among medical staff in the low and moderate WR classes. Additionally, in these two classes, there were significant relationships in which rumination and WR classes had a chain-mediated nature about work requirements and mental distress. This suggests that future intervention studies should focus on these two classes and develop psychological health interventions for hospital staff according to different WR classes.
