匹兹堡睡眠质量指数在军人中应用的信效度研究

Study on the reliability and validity of the pittsburgh sleep quality index scale in its application among military staff

目的探讨匹兹堡睡眠质量指数(pittsburgh sleep quality index,PSQI)量表在军人中应用的信度和效度。方法采用Buysse编制的PSQI量表,选取健康官兵1 157名作为本次调查的研究样本,采用内部一致性信度Cronbach'α系数分析量表的信度,采用因子分析法评估量表的效度。结果 PSQ I量表在军人群体中的可接受率良好,同质性信度在0.537~0.846之间,Cronbach'α系数为0.833,分半信度为0.853,所获得的7个主成分,累积贡献率为58.42%,其载荷取值均在0.475~0.868。PSQI量表的7个因子与相应的PSQI总分具有显著相关性(P<0.05或0.01)。结论 PSQ I量表在军人中应用接受性好,具有较好的信度和效度,可用于基层部队睡眠质量的评估。

Objective To investigate the reliability and validity of the Pittsburgh Sleep Quality Index（PSQI） scale in its application among military staff.Me thods 1 157 military officers were selected in Jinan Military Region as the research subjects of this survey to be assessed by PSQI scale prepared by Buysse.Internal consistency reliability Cronbach was adopted to assess the reliability coefficient and the factor analysis assessment scale was adopted to assess validity.Re s ults The PSQI scale was well accepted in military groups and homogeneity reliability was between 0.537 to 0.846.Cronbach the coefficient α was 0.833 and split-half reliability was 0.853.The cumulative contribution rate of seven principal components obtained was 58.42% and their load values were 0.475 to 0.868.The seven factors and their corresponding PSQI scores were significantly correlated（ P〈0.05 or 0.01）.Conclus ion Enjoying good reliability and validity,PSQI scale is well accepted by the military staff and can be used to assess sleep quality of grassroot military units.
