A structural equation model of the relationship among occupational stress, coping styles, and mental health of pediatric nurses in China: a cross-sectional study

Background Pediatric nurses experience a wide rang of stressful events at work every day, which can trigger a lot of emotional responses. The objectives of this study were mainly to explore the potential interrelationships of occupational stress, coping styles and mental health among pediatric nurse. Methods A total of 381 pediatric nurses from Chongqing, China were recruited in this cross-sectional study. We performed this study based on a questionnaire survey that contained the Chinese Perceived Stress Scale (CPSS), Simplified Coping Style Questionnaire and Symptom-Checklist 90(SCL-90). Results The pediatric nurses reported having health risk stress(HRS) was 54.3%, and nurses with different medical professional titles, style of coping and profiles of mental health had significantly different occupational stress levels (P < 0.01) . And with the application of the Spearman correlation analysis and Structural Equation Modelling were revealed a significant relationship among occupational stress, coping style and mental health. The positive coping style had a negative direct predictive effect on occupational stress ( β = -0.499, P < 0.01 ) and mental health symptoms (β = -0.115, P < 0.01), negative coping styles had positive predictive effect on occupational stress (β = 0.185, P < 0.01) and mental health symptoms (β = 0.205, P < 0.01). Occupational stress had significant impact on mental health symptoms ( β = 0.416, P < 0.01), and it was played a part of mediating effect between coping style and mental health. Conclusion These findings demonstrated significant associations between occupational stress, coping style and mental health in pediatric nurses, and this SEM model highlighted that the potential prediction effects of occupational stress and coping styles for mental health and the mediated effect of occupational stress between coping style and mental health, which we believe facilitates the understanding of these associations. This model should be useful in the formulation of strategies to improve mental health level for this population.
