This study was conducted in order to analyze the effect of the nurses’ quality of work life based on fear about COVID-19 and examine the psychological well-being as a moderating variable in this relationship. The survey questionnaire was administered among nurses between 1 November 2020 and 14 November 2020. The self-report survey comprised the nurse information survey, Fear of COVID-19 Scale, work quality of life scale, and psychological well-being scale as data collection tools. Data were obtained from 339 nurses. The findings show that fear of COVID-19 negatively affects nurses’ quality of work life. It has been determined that PWB plays a moderating role in this relationship. While the fear of COVID-19 negatively affects the quality of work life in nurses with low psychological well-being, there is not any kind of significant effect on the quality of work life in nurses with high psychological well-being. This result shows that as the psychological well-being of nurses’ increases, fear of COVID-19 effect on quality of work life decreases. The results of the study show that responses designed to enhance psychological well-being can enhance nurses' working conditions that could reduce the negative effects of the fear of COVID-19. There is an urgent need for clinical and policy strategies to help increase nurses’ PWB in order to increase the quality of work life by reducing fear and also anxiety among nurses fighting on the front line during COVID-19.
