对基层医务人员基本工作情况进行纸质与电子问卷调查的对比研究

A comparative study on the application of paper and electronic questionnaire on the basic work of grass roots medical staff

目的评价电子问卷在调查基层医务人员工作情况量表时的信度和效度。方法电子版数据采用电子问卷智能手机版,于2017年从四川省9个乡镇卫生院220名医务人员中收集。用克伦巴哈系数评价量表的内部一致性,用重复测量数据的混合效应模型校正人口学变量后,计算问卷条目内相关系数即内部一致性信度;用Amos软件进行验证性因子分析以评价其结构效度。再将以上结果与纸质问卷调查结果比较。结果电子问卷测量基本工作各量表的克伦巴哈系数在0.748～0.942之间,纸质问卷的克伦巴哈系数在0.695～0.924之间。前者大部分条目的因子负荷高于后者,且2/3量表的验证性因子分析拟合指数前者优于后者。结论电子问卷在医务人员基本工作情况的测量中具有较好的信度和效度,且在整体上优于纸质问卷。

Objective To evaluate reliability and validity of electronic questionnaire for working condition scales of grass-root medical staff. Methods The working condition questionnaire data of electronic questionnaires were collected via smart mobile phone from 220 medical staff in 9 township hospitals in Sichuan Province in 2017. Cronbach＇s α coefficient was used to assess the internal consistency reliability of the scales.Demographic factor corrected intra-class correlation coefficient, namely the internal consistency reliability, was estimated using mixed effects model of repeated measurement data. Confirmatory factor analysis was performed to evaluate the questionnaires＇ construct validity using Amos software. The above statistics were compared with the results of the paper-and-pencil based questionnaire. Results The Cronbach＇s α coefficient of individual scale was between 0.748 and 0.942 for electronic questionnaires, and was between 0.695 and 0.924 for paper-and-pencil based questionnaires. Most factor loadings of scale items in the former were higher and the model fitting indices were better than those in the latter. Conclusion The working condition scales collected from grass-root medical staff via electronic survey form has good reliability and validity, and is generally better than that of paper-and-pencil questionnaire form.
