PURPOSE
To explore and validate the factor structure of the Pittsburgh Sleep Quality Index (PSQI) in the collegiate young adults.
METHODS
Six hundred university students were initially contacted and invited to participate in a survey of their sleep experience and history. Of this preliminary sample 418 of the students (age = 20.92 ± 1.81 years, BMI = 23.30 ± 2.57 kg/m(2)) fulfilled the screening criteria and ultimately completed the Pittsburgh Sleep Quality Index (PSQI), a self-report survey of respondents' sleep habits and sleep quality. The students were enrolled in various undergraduate and postgraduate programs at Jamia Millia Islamia, New Delhi, India. Exploratory factor analysis (EFA) investigated the latent factor structure of the scale. Confirmatory factor analysis evaluated both of the models found by EFA.
RESULTS
The Kaiser's criteria, the Scree test, and the cumulative variance rule revealed that a 2-factor model accounted for most of the variability in the data. However, a follow up Parallel Analysis found a 1-factor model. The high correlation coefficient (r = 0.91) between the two factors of the 2-factor model and almost similar values of the fit indices supports the inference that the PSQI is a unidimensional scale.
CONCLUSIONS
The findings validate the 1-factor model of the PSQI in the collegiate young adults.
目的
探讨并验证匹兹堡睡眠质量指数（PSQI）在大学生中的因子结构。
方法
最初联系了600名大学生并邀请他们参与一项关于睡眠经历和睡眠史的调查。在这个初步样本中，418名学生（年龄 = 20.92 ± 1.81岁，体重指数 = 23.30 ± 2.57 kg/m²）符合筛选标准并最终完成了匹兹堡睡眠质量指数（PSQI），这是一项关于受访者睡眠习惯和睡眠质量的自我报告调查。这些学生就读于印度新德里贾米亚米利亚伊斯兰大学的各种本科和研究生课程。探索性因子分析（EFA）研究了该量表的潜在因子结构。验证性因子分析评估了EFA找到的两个模型。
结果
凯泽准则、碎石图检验和累积方差规则表明，一个双因子模型解释了数据中的大部分变异性。然而，后续的平行分析发现了一个单因子模型。双因子模型的两个因子之间的高相关系数（r = 0.91）以及拟合指数的几乎相似的值支持了PSQI是一个单维量表的推断。
结论
研究结果验证了PSQI在大学生中的单因子模型。
