This study aimed to evaluate the validity and reliability of the Persian version of the Bergen Shift Work Sleep Questionnaire (BSWSQ) in Iranian nurses. This cross-sectional study was performed on nurses in Kashan using simple random sampling. The original text of the BSWSQ was translated into Persian using the direct-reverse method. The Persian version of the questionnaire was culturally adapted performed. After collecting and scoring the questionnaires, the construct validity was performed using exploratory and confirmatory factor analysis. Convergent and divergent validity were also performed. Spearman correlation coefficient, Cronbach’s alpha, and ICC calculation were also used to measure reliability. A total of 280 people participated in this study, of which 77.2% were female. Cronbach’s alpha of the total BSWSQ was 0.83. The intra-class correlation index (ICC) was calculated as 0.88 (0.93–0.8) using the test-retest method to estimate the reliability of the tools. Exploratory factor analysis explained 75% of the total variance. This study showed that the Persian translation of the BSWSQ has good validity and reliability for assessing nurses’ sleep in the Iranian population. This tool can be a standard tool for assessing sleep quality in employees with work shift rotations.
