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

Recent studies indicate that nurses experienced high levels of occupational burnout and insomnia during and after the pandemic and highlight resilience as a crucial competence for overcoming adversity. The aim of this study was to assess occupational burnout, insomnia, and psychological resilience and to explore their interrelations among Greek nurses 14 months after the official ending of the pandemic which was declared in May 2023. 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%. Multiple regression analysis indicated that CBI explained 34.4% of the variance in the AIS scores, while an additional 3% was explained by the BRS. Mediation analysis revealed that resilience operates protectively as a negative mediator in the relationship between burnout and insomnia. In conclusion, one year after the end of the pandemic the levels of occupational burnout and insomnia among nurses remain high, whereas psychological resilience seems to be retained at moderate levels. Consequently, there is an urgent need to regularly monitor for risk of burnout and insomnia and to implement resilience-building strategies for nurses to combat burnout and improve insomnia symptoms.
