Little is known about the impact of the pandemic on frontline and non-frontline nurses working with COVID-19 patients. The aim of this study was to compare mental disorders (sleep disorders, sleepiness, depression, anxiety, and fear) of frontline nurses of COVID-19 with non-frontline nurses. Instruments & Methods: This comparative correlational study was conducted on 240 frontline and non-frontline nurses of COVID-19 who were selected by simple random sampling method in 2020 in hospitals affiliated to Khoy University of Medical Sciences. Data collection tools included demographic information questionnaire, Pittsburgh Sleep Disorders Index, Epworth Sleepiness Scale, Goldberg Questionnaire, Corona Disease Anxiety Scale, and Numerical Rating Scale. The results were analyzed using SPSS 20 software. Findings: Mean scores of sleep disorder, sleepiness, depression, anxiety, and fear in frontline nurses were 10.27±2.34, 18.85±3.90, 30.11±7.05, 25.40±8.90, 6.07±2.17, respectively, and in non-frontline nurses was 7.20±1.65, 15.35±3.80, 24.34±3.56, 21.60±7.23,4.90±1.62. The mean scores in both groups were moderate, but the difference between the mean scores of the frontline nurses was significantly greater than that of non-frontline nurses (p<0.05). There was a direct and significant correlation between the studied variables with age, gender, marital status, number of children and years of work and an inverse and significant correlation with shift work (p<0.05). Conclusion: The Mean scores of sleep disorder, sleepiness, depression, anxiety and fear in frontline nurses and in non-frontline nurses are moderate, but these mental disorders are more common in frontline nurses than in non-frontline nurses.
