目的：本研究的目的是确定波斯语版匹兹堡睡眠质量指数在老年人中的效度和信度。材料与方法：采用方法学研究进行验证性因子分析。通过整群抽样，共抽取598名老年人。除了分析PSQI的三因素结构外，还对其内部一致性信度、结构效度和并发效度进行了检验。使用其他类似的工具，如睡眠健康、Epworth嗜睡、失眠严重程度、全球睡眠评估和柏林指数来检验PSQI的结构可信度。最后，通过多变量回归分析评估PSQI并发效度，所有统计分析均采用SPSS和AMOS软件进行。结果：经Cronbach's alpha检验的信度为0.81。验证性因子分析指标支持结构方程模型的拟合优度。验证性因子分析表明，PSQI的三因素结构chi(2) / DF的比值为2.66，模型的拟合优度指标可接受（RMSEA=0.053， CFI=0.98， TLI=0.96， NFI=0.97， GFI=0.99）。此外，PSQI的内部一致性为0.81，量表相关评分范围为0.48 ~ 0.71。结论：波斯语版匹兹堡睡眠质量指数在伊朗老年人群中具有一定的效度和信度，可作为其他研究的参考工具。
Objective: The purpose of this study is to determine the validity and reliability of the Persian version of the Pittsburgh Sleep Quality Index in the elderly population. Material and Methods: A methodological study was conducted as a confirmatory factor analysis. Totally, 598 elderly people were selected through cluster sampling. In addition to analyzing the three-factor structure of PSQI, internal consistency reliability, structural validity, and its concurrent validity were examined. The structural credibility of PSQI was examined using other similar tools such as Sleep Health, Epworth Sleepiness, Insomnia Severity, Global Sleep Assessment, and Berlin indices. Finally, the concurrent criterion validity of PSQI was evaluated through multivariable regression analysis and all statistical analyzes were performed using SPSS and AMOS software. Results: The reliability of the test according to Cronbach's alpha was 0.81. Confirmatory factor analysis indicators supported goodness of fit of the structural equation model. The confirmatory factor analysis showed that the ratio of chi(2) / DF was 2.66 for the three-factor structure of PSQI and the goodness of fit indices of model were acceptable for this structural model (RMSEA=0.053, CFI=0.98, TLI=0.96, NFI=0.97, GFI=0.99). In addition, the internal consistency of the PSQI was 0.81 and the scales correlation score ranged from 0.48 to 0.71. Conclusion: The results indicated that Persian version of Pittsburgh Sleep Quality Index had the required validity and reliability for the elderly population of Iran and it can be used as a useful tool by other studies.
