Occupational Burnout and Insomnia in Relation to Psychological Resilience Among Nurses in Greece in the Post-Pandemic Era

Recent studies indicate that nurses experienced higher levels of occupational burnout and insomnia during the pandemic compared to other healthcare professionals. The aim of this study was to assess occupational burnout, insomnia, and psychological resilience and to explore their interrelations among nurses in Greece in the post-pandemic era. The study was conducted online in July 2024 and included 380 nurses currently working in Greek hospitals, who completed the Copenhagen Burnout Inventory (CBI), the Athens Insomnia Scale (AIS), and the Brief Resilience Scale (BRS). Overall, 56.1% of the nurses exhibited insomnia symptoms and 46.8% displayed signs of occupational burnout. Low resilience scores were observed in 26.3%. Female nurses had a higher mean burnout score compared to their male counterparts. Multiple regression analysis indicated that CBI Total explained 34.4% of the variance in the AIS scores, with an additional 3% explained by BRS. Mediation analysis further revealed that resilience operates protectively as a negative mediator in the relationship between burnout and insomnia. In conclusion, the levels of occupational burnout and insomnia among nurses remain high one year after the end of the pandemic and consequently there is an urgent need to enhance the support for nurses to protect them from adverse physical and psychological effects.
