To clarify how long working hours affect the likelihood of current and future depression.
Using data from four repeated measurements collected from 218 clerical workers, four models associating work-related factors to the depressive mood scale were established. The final model was constructed after comparing and testing the goodness-of-fit index using structural equation modeling. Multiple logistic regression analysis was also performed.
The final model showed the best fit (normed fit index = 0.908; goodness-of-fit index = 0.936; root-mean-square error of approximation = 0.018). Its standardized total effect indicated that long working hours affected depression at the time of evaluation and 1 to 3 years later. The odds ratio for depression risk was 14.7 in employees who were not long-hours overworked according to the initial survey but who were long-hours overworked according to the second survey.
Long working hours increase current and future risks of depression.
阐明工作时长如何影响当前和未来抑郁的可能性。
利用来自 218 名办事员的四次重复测量数据，建立了四个将与工作相关因素与抑郁情绪量表相关联的模型。通过使用结构方程建模比较和测试拟合优度指数，最终构建了最终模型。还进行了多变量逻辑回归分析。
最终模型显示出最佳拟合（归一化拟合指数=0.908；拟合优度指数=0.936；均方根误差近似值=0.018）。其标准化总效应表明，长时间工作会影响评估时和 1 至 3 年后的抑郁状况。与初始调查中未超时工作但根据第二次调查超时工作的员工相比，抑郁风险的比值比为 14.7。
长时间工作会增加当前和未来的抑郁风险。
