Mediating effect of sleep disturbance and rumination on work-related burnout of nurses treating patients with coronavirus disease

BACKGROUND: COVID-19 has created significant and unprecedented psychological distress on nurses working with COVID-19 patients. Nurses dealing with such psychological distress are prone to burnout. This study examined the mediating role of sleep disturbance and rumination in the association between psychological distress and work-related burnout of nurses treating COVID-19 patients. METHODS: A cross-sectional study was conducted from 26th February to 16th March 2021, on a sample of 250 nurses who were actively working during the COVID-19 pandemic in five referral hospitals in Tehran, Iran. The Oldenburg Burnout Inventory, Kessler Psychological Distress Scale (K10), Pittsburgh Sleep Quality Index, and Ruminative Responses Scale were used to collect data. Data analysis was based on pearson’ correlation analysis and path analysis. RESULTS: Psychological distress has a significant effect on job burnout. When sleep disturbances were modeled as a mediator, path coefficients of psychological distress showed a significant effect on job burnout. Also, according to the findings, rumination poses a significant mediating effect on the association between psychological distress and job burnout. CONCLUSION: This study demonstrated the importance of designing psychological interventions intended to reduce sleep disturbances and rumination when experiencing stressful events to avoid job burnout among nurses.
