The current study investigated the factor structure of the Pittsburgh Sleep Quality Index (PSQI) among English speaking non-Hispanic whites (NHW) and English and Spanish speaking Hispanics of Mexican descent (HMD).
The PSQI was administered during a telephone interview. In order to test the factor structure of the PSQI structure across ethnic/language groups, multiple group confirmatory analysis with covariates (MIMIC) was employed. The 1- and 3-factor versions of the PSQI previously reported in the literature were examined.
San Diego County.
Community-dwelling English speaking, NHW (n = 1,698) and English (n = 654) and Spanish (n = 792) speaking HMD.
A single-factor scoring model fit across language/ethnic groups; however, a 3-factor model provided a better than the 1-factor model in all language/ethnic groups. The subscale sleep medications loaded poorly and was removed from all models.
Across groups, a 3-factor model of the PSQI more reliably assessed sleep quality than a single-factor global score. Results indicate that the 3-factor structure of the PSQI was uniform across English speaking NHW and English and Spanish speaking HMD.
本研究旨在调查匹兹堡睡眠质量指数（PSQI）在讲英语的非西班牙裔白人（NHW）和讲英语及西班牙语的墨西哥裔西班牙裔（HMD）中的因素结构。
PSQI 通过电话访谈进行。为了检验 PSQI 结构在不同种族/语言群体中的因子结构，采用了带有协变量的多组验证性分析（MIMIC）。文献中先前报道的 PSQI 的 1 因子和 3 因子版本进行了检验。
圣地亚哥县。
居住在社区中的讲英语的 NHW（n=1698）和讲英语（n=654）和西班牙语（n=792）的 HMD。
单一因子评分模型在所有语言/种族群体中均适用；然而，在所有语言/种族群体中，3 因子模型均优于 1 因子模型。睡眠药物的亚量表负荷不佳，因此从所有模型中删除。
在所有群体中，PSQI 的 3 因子模型比单一的全球总评分更可靠地评估了睡眠质量。结果表明，PSQI 的 3 因子结构在讲英语的 NHW 和讲英语及西班牙语的 HMD 中是一致的。
