Work Ability and Sleep Quality amongst Shift-Work Nurses

Nurses are forced to shift work due to the nature of their job. This shiftwork can reduce their sleep time and affects the quality of their performance and work ability. The aim of this study was to investigate the effect of sleep quality on the work ability of nurses in Sari hospitals. This cross-sectional study was conducted among Sari hospitals in 2017. Participants included 200 nurses selected by random selection. The Persian version of Pittsburgh’s sleep quality questionnaires and Work Ability Index (WAI) were used to collect data. Descriptive statistics, Spearman correlation, and linear regression tests were used for statistical tests. The mean±SD age of participants was 33.52 ± 7.22 years. The participants' mean±SD work ability was 37.55 ± 5.50, categorized at the good level. The average sleep quality score was 8.79 ± 3.80. The findings showed a significant and inverse correlation between sleep quality and work ability. This study confirmed that sleep quality had a high effect on nurses' work ability and performance.
