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.

Background/Objectives: Several studies have reported alarming rates of mental health issues and sleep problems among nurses even in the post-pandemic era. The objective was to investigate the prevalence of stress, anxiety and depressive symptoms, burnout and insomnia among nurses in Greece one year after the end of the pandemic and to construct a mediation model evaluating the impact of stress on insomnia, the chain mediating roles of depressive symptoms and burnout, as well as the moderating role of anxiety symptoms in the model. Methods: This cross-sectional study was conducted online in July 2024 and included 380 hospital nurses who completed the Depression Anxiety Stress Scale (DASS-21), the Copenhagen Burnout Inventory (CBI) and the Athens Insomnia Scale (AIS). Results: The prevalence rates of stress, anxiety and depressive symptoms, burnout and insomnia were 33.9% with 95% confidence interval (CI): [0.292, 0.390], 33.3% (95% CI: [0.284, 0.381]), 35% (95% CI: [0.302, 0.400]), 46.8% (95% CI: [0.399, 0.502]) and 56.1% (95% CI: [0.509, 0.611]), respectively. Multiple regression analysis indicated that the Depression subscale of the DASS-21 explained 40.6% of the variance in the AIS, while an additional 7.6% was explained by the CBI and another 1.3% rate by the Stress subscale of the DASS-21. Mediation analysis revealed that stress affected insomnia both directly and indirectly through the chain mediating roles of depressive symptoms and burnout. Anxiety symptoms moderated the chain mediation path by enhancing the negative impact of stress on depressive symptoms. Conclusions: The proposed moderated chain mediation model introduces certain factors influencing insomnia and explains how changes in any one of these factors effectuate changes in the other factors, offering insights for individualized interventions.

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.
