住院患者满意度调查问卷的效度评价

目的应用结构方程模型评价自行编制的住院患者满意度调查问卷的结构效度。方法采用系统抽样方法，于2016年4月现场发放问卷，调查四川省某三甲医院住院患者。采用Lisrel8.70软件，应用结构方程模型评价问卷的结构效度。结果本次调查问卷有效回收率为98.5%，共2562名住院患者纳入分析。自行编制的住院患者满意度调查问卷具有较优的结构效度，最终模型拟合结果显示，χ²/df=8.36，渐进残差均方和平方根（RMSEA）=0.054，残差均方和平方根（RMR）=0.021,适配度指数（GFI）=0.93，调整后GFI（AGFI）=0.91，比较适配指数（CFI）=0.98，非规准适配指数（NNFI）=0.98，简约GFI（PGFI）=0.74；外生潜变量的各条目因子载荷为0.59~0.94，AVE为0.52~0.87。结论最终模型的拟合指标均达到统计学要求，拟合效果理想，适配度良好，问卷的效度佳，可应用于三甲医院住院患者满意度评价。

英文摘要:

Objective To assess the validity of the self-designed inpatient satisfaction questionnaire using Structural Equation Model (SEM). Methods The questionnaire survey was conducted in a tertiary hospital in Sichuan in April 2016, with participants selected through a systematical sampling approach. The structural validity of the inpatient satisfaction questionnaire was assessed using SEM. The statistical analyses were performed using Lisrel8.70. Results About 98.5% of returned questionnaires were valid for data analyses, which resulted in a total sample of 2562. A good model fit was achieved: df=8.36, root mean square error of appoximation (RMSEA)=0.054, root mean square residual (RMR)=0.021, goodness-of-fit index (GFI)=0.93, adjusted GFI (AGFI)=0.91, com-parative fit index (CFI)=0.98, non-normed fit index (NNFI)=0.98, parsimony GFI(PGFI）=0.74. Factor loadings on exogenous latent variables ranged from 0.59 to 0.94, with 0.52-0.87 AVE. Conclusion The questionnaire has a good construct validity, which can be used for evaluating inpatient satisfaction in tertiary hospitals.
