To investigate mental workload among nurses from tertiary hospitals in Shandong Province, and analyze various factors related to mental workload. From May to July 2019, a cluster sampling method was used to select 8255 nurses from 20 third class a general hospitals in 16 cities of Shandong Province as the research objects, and 8159 valid questionnaires were collected. The general information and psychological load of nurses were investigated by general information questionnaire and task load index scale. The measurement data were expressed in percentage (%) ; the nurses' psychological load scores were in accordance with normal distribution, and the differences between groups were compared by t-test or ANOVA; the related influencing factors of nurses' psychological load were analyzed by multiple stepwise regression analysis. The average scores of mental workload among nurses was 77.83 (SD=12.88) . Time demands and physical demands were the two highest rated dimensions of mental workload. the average scores were 90.77 (SD=12.47) and 79.92 (SD=15.23) . Multiple stepwise regression analysis showed that Satisfaction with income, monthly average night shift and professional titles were the significant predictors of mental workload ((2)=0.08) . Nurses with higher psychological load, lower income satisfaction, higher number of night shifts per month and lower title have higher psychological load.
为调查山东省三级医院护士的心理负荷，并分析与心理负荷相关的各种因素。2019年5月至7月，采用整群抽样方法，从山东省16个城市的20家三级甲等综合医院中选取8255名护士作为研究对象，共收集到有效问卷8159份。通过一般信息问卷和任务负荷指数量表对护士的一般信息和心理负荷进行调查。计量资料以百分比（%）表示；护士心理负荷得分符合正态分布，组间差异采用t检验或方差分析进行比较；采用多元逐步回归分析护士心理负荷的相关影响因素。护士心理负荷平均得分为77.83（标准差=12.88）。时间需求和体力需求是心理负荷评分最高的两个维度，平均得分分别为90.77（标准差=12.47）和79.92（标准差=15.23）。多元逐步回归分析显示，收入满意度、月平均夜班次数和职称是心理负荷的显著预测因素（（2）=0.08）。心理负荷较高、收入满意度较低、每月夜班次数较多且职称较低的护士心理负荷较高。
