【摘要】：目的评价匹兹堡睡眠质量指数(PSQI)在农村老年人群中的信度和效度。方法采用分层整群随机抽样的方法,从四川省某市农村地区选取共318名年龄≥60岁的老年人作为研究对象。用分半信度、内在一致性信度考察其信度,用区分效度、结构效度考察其效度。结果观察对象PSQI分半信度系数为0.833;16个条目总体Cronbach'sα系数为0.767;7个成分间区分效度定标试验成功概率为100%;验证性因子分析显示双因子模型和三因子模型拟合较好(RMESA、NFI、CFI各自为0.037、0.972、0.992;0.000、0.992、1.000)。结论 PSQI量表用于农村老年群具有良好的信度和效度,双因子结构和三因子结构模型均适用于农村老年人群体。考虑到三因子结构两个因子内部内在一致性较低,在农村老年人中使用PSQI量表以双因子结构更为合适。
[Abstract]:Objective to evaluate the reliability and validity of Pittsburgh Sleep quality Index (PSQI) in rural elderly population. Methods using stratified cluster random sampling, 318 elderly people aged more than 60 years were selected from a rural area of Sichuan province as the research object. The reliability was evaluated by split-half reliability, intrinsic consistency reliability, distinguishing validity and structural validity. Results the PSQI split-half reliability coefficient was 0.833; the total Cronbach's 伪 coefficient of 16 items was 0.767; the probability of success in the discriminant validity calibration test among 7 components was 100; and the confirmatory factor analysis showed that the double-factor model and the three-factor model fitted well (RMESA,NFI,CFI was 0.037 0. 972X 0.9920.000 0.9921.000 respectively). Conclusion the PSQI scale has good reliability and validity in the rural elderly group, and the two-factor structure and three-factor structure model are suitable for the rural elderly population. Considering that the internal consistency of the two factors is low, it is more appropriate to use the PSQI scale in the rural elderly to use the two-factor structure.
