ABSTRACT

Objective To investigate the fatigue status and influencing factors of nurses,and to evaluate whether trait coping styles mediate the relationship between occupational stress and fatigue.Methods A total of 167 nurses in Shaoxing Municipal Hospital were selected by cluster random sampling in April,2018.Their fatigue status was assessed by Chinese version of multidimensional fatigue scale,occupational stress was assessed by occupational stress inventory revised edition,and trait coping style was assessed by trait coping style questionnaire.The data were analyzed by SPSS22.0.Results A total of 164 valid questionnaires were obtained,the physical fatigue score was (22.9 ± 9.3) points,the decreased activity score was (6.7 ± 2.7) points,the decreased motivation score was (6.6 ± 2.6) points,the mental fatigue score was (9.0 ± 4.0) points,the total fatigue score was (47.3 ± 13.5) points.The total fatigue scores of nurses with different ages(F =2.520,P =0.043),nursing years(F =3.388,P =0.020),educational background(t =-2.571,P =0.011),professional tide (F =3.743,P =0.026),departments (F =4.412,P =0.001) and night shift frequency (F =3.412,P =0.019) were significantly different.The total fatigue scores were positively correlated with negative coping (r =0.274,P =0.009),occupational tasks (r =0.351,P =0.007) and stress response (r =0.348,P =0.004) respectively.Negative coping styles partially mediated the relationship between occupational stress and fatigue.The total effect of occupational stress on fatigue was 0.066,the ratio of negative coping to total effect was 49.62％.Conclusion There are many factors influencing nurses'fatigue,and negative coping styles play a mediating role between occupational stress and fatigue.
