Cross-sectional questionnaire data were used to compare the levels of job strain in shift and daytime workers. Job strain was measured according to Karasek's Demands/Discretion model. Four occupational groups were included: drivers, industrial workers, policemen/watchmen, and cooks. The study subjects were a random sample of 508 daytime workers and 418 shift workers. Job demand did not differentiate between shift and daytime workers, comparing groups broken down by gender and by occupation. The daytime workers reported higher levels of job strain than the shift workers, and women experienced a higher level of job strain than did men. Multiple linear regression analysis showed that only occupational group and gender predicted job strain level. Shiftwork was not significantly associated with job strain in the regression model.
采用横断面问卷调查数据比较轮班工人和日班工人的工作压力水平。工作压力根据Karasek的需求/自主性模型进行测量。研究纳入了四个职业群体：司机、产业工人、警察/保安和厨师。研究对象为508名日班工人和418名轮班工人的随机样本。按性别和职业细分群体后比较发现，工作需求在轮班工人和日班工人之间没有差异。日班工人报告的工作压力水平高于轮班工人，女性经历的工作压力水平高于男性。多元线性回归分析表明，只有职业群体和性别可预测工作压力水平。在回归模型中，轮班工作与工作压力没有显著关联。
