RESUMO
Objectives@#This study aimed to explore how the coronavirus disease-2019 (COVID-19) pandemic affected the mental health of university hospital nurses with a focus on their resilience, stress, depression, anxiety, and sleep. @*Methods@#A total of 220 nurses working at a university hospital in South Korea during the COVID-19 pandemic participated in this study. The collected data were subjected to analysis based on the percentage, mean, standard deviation, Kruskall-Wallis test, Mann-Whitney test, and Pearson correlation coefficient using the IBM SPSS Statistics 25 program. @*Results@#The range of the Brief Resilience Scale was 1.3 to 5.0 (3.2±0.6), Perceived Stress Scale was 4 to 34 (18.6±5.3), Pittsburgh Sleep Quality Index was 2 to 17 (7.4±3.1), Patient Health Questionnaire was 0 to 18 (5.0±4.0), and General Anxiety Disorder-7 was 0 to 16 (3.4±3.4). The range of the difference in job stress before and after the COVID-19 pandemic outbreak was -5 to +7 (2.2±1.9). There was a negative correlation between the nurses’ resilience and stress, depression, anxiety, and sleep. @*Conclusion@#Most of the nurses experienced high levels of stress, depression, anxiety, and poor sleep quality during the COVID-19 pandemic. The mental health of nurses should be carefully monitored with interest, and various compensatory systems should be developed to help them cope with the situation.
