The present study aimed to investigate the relationship between shift work and cognitive performance in nurses. The present before-after study included 35 female nurses 25-40 years old with similar mental and physical workload. Working memory, response time and attention were assessed using Wechsler and Stroop tests. The variables were measured at the beginning and the end of three working shifts (morning, afternoon and night). An interval of 3 days was considered for performing an after-shift test to eliminate the learning effect. Data were analyzed using repeated-measures analysis of variance (ANOVA). At the end of all three shifts, nurses' working memory (= 0.039) and interference score (= 0.04) were significantly decreased, but their response time was not significantly affected during a shift. The decrease in working memory after the night shift was significantly higher than after the morning and evening shifts (< 0.001). The results of this study showed that shift work can affect some aspects of cognitive function (working memory and attention) in nurses, and this effect was more prominent after a night shift.
本研究旨在探讨轮班工作与护士认知表现之间的关系。本前后研究纳入了 35 名年龄在 25-40 岁之间、脑力和体力负荷相似的女性护士。使用韦氏和斯特鲁普测试评估工作记忆、反应时间和注意力。在三个工作班次（早班、中班和夜班）开始和结束时测量变量。为了消除学习效应，在轮班后测试中考虑了 3 天的间隔。使用重复测量方差分析（ANOVA）对数据进行分析。在所有三个班次结束时，护士的工作记忆（=0.039）和干扰评分（=0.04）明显下降，但反应时间在轮班期间没有明显变化。夜班后工作记忆的下降明显高于早班和中班后（<0.001）。本研究结果表明，轮班工作会影响护士认知功能（工作记忆和注意力）的某些方面，而这种影响在夜班后更为明显。
