住院患者体验量表的信效度评价

Reliability and validity assessment of inpatient experience questionnaire

目的：对“住院患者体验量表”进行信效度评价。方法：采用整群随机的抽样方式于2012年7月至8月对河南省某医院的住院患者672人进行问卷调查，通过信度分析、因子分析等方法对量表的信度和结构效度进行评价。结果：量表的总体克朗巴赫α系数和分半信度系数分别为0．939、0．966，各维度的克朗巴赫α系数和分半信度系数均＞0．7，各条目与条目总分的相关系数介于0．503～0．716。 KMO值为0．931，经探索性因子分析后共提取6个公因子，累计方差贡献率为63．843％。经验证性因子分析，除拟合优度指数GFI未达到最优标准之外，该模型的χ2/df为2．366，比较拟合指数CFI、Tucker-Lewis指数TLI均大于0．9，近似误差均方根RMSEA为0．064，均方根残差RMR＜0．05。结论：该量表拥有良好的信效度。

Aim： To evaluate the reliability and validity of inpatient experience questionnaire （ IPEQ ） .Methods：Cluster sampling method was used to sample 672 inpatients in a hospital of Henan Province from July 2012 to August 2012 for IPEQ survey.Reliability analysis and factor analysis methods were adopted to evaluate the reliability and constructive validity.Results：The Cronbach＇αand split-half reliability of the questionnaire were 0.939 and 0.966, all dimensions＇αand split-half reliability were above 0.7, and the correlation coefficient of each item score to the total was between 0 5.03 and 0.716.KMO was 0.931, and exploratory factor analysis showed the cumulative contribution rate of 6 factors was 63.843%.Confirmatory factor analysis showed except GFI did not reach optimal standard ,χ2/df was 2.366, CFI and TLI was above 0.9, RMSEA was 0.064, and RMR was under 0.05.Conclusion：IPEQ shows good reliability and validity and is easy to accept .
