Outline
To explore the chain-mediated relationship between worker occupation fit (WOF) and occupational stress between occupational fatigue and depressive symptoms.
The method of stratified cluster sampling was used to study the medical staff in Sichuan Province. Pearson correlation analysis, stepwise regression model, and bootstrap method were used to analyze the relationship and chain mediating effect among WOF, occupational stress, occupational fatigue, and depression.
In total 1 988 subjects were enrolled in this study, of which 43.5% (864/1 988) had depressive symptoms, and 6.5%(130/1 988) had severe depressive symptoms; 31.1% (618/1 988) had occupational fatigue symptoms, and the WOF level was 31.6±7.1. Stepwise regression analysis showed that with WOF, WOF type and occupational stress added to the model, the explanation of depressive symptoms in the model increased by 37.3% and 41.4%, respectively. Intermediary effect analysis showed that WOF and occupational stress had chain mediating effect between occupational fatigue and depressive symptoms, and the proportion of chain mediating effect was 1.80% (β = 0.020, bias corrected and accelerated 95%CI: 0.016-0.039).
The occurrence of depressive symptoms in medical staff is not only affected by occupational fatigue but also mediated by WOF and occupational stress.
