摘　　要：目的运用匹兹堡睡眠质量指数(pittsburgh sleep quality index,PSQI)中文版对患有近视的青少年人群进行信度和效度分析。方法通过分层整群随机的方法进行抽样,用分半信度、内在一致性信度及重测信度评价量表信度,用结构效度、效标关联效度和ROC曲线评估量表效度。结果样本人群的PSQI量表的总分为(3.67±2.57)分,不同年龄段PSQI得分有统计学差异(P<0.05),而性别无统计学差异,人群的睡眠障碍阳性率为9.49%;信度方面,量表条目与维度的分半信度分别为0.665、0.672,条目与维度的Cronbach'sα系数分别为0.680、0.616;效度方面,通过因子模型间的对比,修订后的二因子模型中χ~2值、GFI、CFI、AIC、CAIC、ECVI等指标分别为70.95、0.97、0.84、96.95、162.45、0.22。效标关联效度只有"催眠药物应用"维度无统计学意义(P>0.05)。ROC曲线下面积为0.889(95%CI:0.859～0.919,P<0.05)。当截断值为0.647时,量表的敏感性和特异性分别为91.32%和73.40%。结论 PSQI量表运用到患有近视的青少年人群中具有良好的信度和效度。Objective To evaluate the reliability and validity of the Chinese version of Pittsburgh Sleep Quality Index(PSQI)in adolescents with myopia.Methods Eligible participants in this study were recruited by performing a stratified clustering random method.The reliability of the scale was evaluated by semi reliability,internal consistency reliability and retest reliability;the validity of the structure validity,the validity of the standard effect and the ROC subjects curve were used to evaluate the validity of the scale.Results The total score of PSQI in the study population was 3.63 ±2.54.The difference between age groups was statistically significant(P<0.05),but not between genders.The prevalence of dyssomnia was 9.49% in the study population.In reliability,the semi-reliability of items and dimensions was 0.665 and 0.672.The Cronbach's alpha coefficient of the scale items and the dimensions was 0.680 and 0.616.In validity,by comparing the factor models,the indexes of X^2,GFI,CFI,AIC,CAIC and ECVI in the revised 2-factor model were 70.95,0.97,0.84,96.95,162.45 and 0.22 respectively.There was no significant difference in scale related validity(P>0.05).The area under the ROC curve was 0.889(95% CI:0.859-0.919,P<0.05).When the cut-off value was 0.647,the sensitivity and specificity of the scale were 91.32% and 73.40%,respectively.Conclusion The PSQI scale has a good reliability and validity among adolescents with myopia.
