Objective: The Coronavirus Diseases 2019 (COVID-19) pandemic has severely affected healthcare systems. Nurses have played a vital role in this pandemic. However, increases in stress levels from exposure to high-risk environments can negatively impact nurses’ mental health, affecting their performance. This study aims to explore the prevalence of perceived stress levels and the factors associated with psychological stress among nurses during the COVID-19 pandemic in Macau. Methods: This cross-sectional descriptive study recruited registered nurses in Macau to participate in an online questionnaire through nurses’ social media platforms using a convenience sampling method in August and September 2022. Self-administered questionnaires consisting of sociodemographic characteristics and working conditions, the 10-item Perceived Stress Scale (PSS-10), Brief Coping Orientation to Problems Experienced Inventory (Brief COPE), and Social Support Questionnaire (SSQ6) were used. Descriptive statistics were used to analyze the sociodemographic characteristics and working conditions, level of perceived stress, coping strategies, and current status of social support. Multivariate regression analysis was used to analyze factors associated with perceived stress among nurses in Macau. Results: A total of 167 nurses participated in this study; 90% of the respondents were female, and 63% were under the age of 40. The prevalence of perceived stress was 20.05±6.4 (70.1% reported moderate levels of stress) among Macau nurses. The top five coping strategies respondents tended to use were acceptance, active coping, positive reframing, planning, and the use of instrumental support. The support number of the participants was 1.89±1.45 persons (0–9 persons), and the support satisfaction score was 2.51±1.02 (1–6 scores). Bivariate correlational analyses found that smoking, alcohol drinking, insomnia, poor appetite, fatigue, confidence to work in an isolated ward, time to join the infectious control training, and fear of being infected had a statistically significant association with perceived stress (all p<0.05). The PSS score had a significantly positive correlation with support satisfaction, substance use, behavioral disengagement, denial, humor, and self-blame (p<0.05; r=0.208–0.518), and a significantly negative correlation with support number, active coping, use of instrumental support, positive reframing, planning, and acceptance (p<0.05; r=-0.222–-0.362). Finally, multivariate regression analysis found that eight independent variables (fatigue, support satisfaction, self-blame, denial, insomnia, fear of being infected, smoking, and active coping) explained the 59.5% variance in PSS scores. Conclusion: The perceived stress level of nurses during the COVID-19 pandemic in Macau is moderate to high. Fatigue, support satisfaction, self-blame, denial, insomnia, fear of being infected, and smoking are risk factors for higher perceived stress levels among nurses, while active coping strategies reduce perceived stress levels. Nurses should be aware of the importance of stress management and effective coping strategies. Healthcare organizations should consider periodic infection control refreshment courses to alleviate nurses’ fear of being infected. In addition, psychological and physical intervention programs should be developed for nurses to help them reduce stress during the COVID-19 pandemic.
