本研究旨在探讨匹兹堡睡眠质量指数（PSQI）在类风湿关节炎（RA）中的因子结构。样本包括107例RA患者，88例女性和7例男性，平均年龄为56.09岁，从大南加州地区招募。影响因素分析评价了单因素、双因素和三因素模型。单因素解决方案与数据的拟合度较差。虽然三因素解决方案具有最佳拟合，但由睡眠效率和感知睡眠质量因素组成的双因素解决方案是最佳的，因为它具有非常好的拟合，并且其各个因素的可靠性可接受。临床指标始终与睡眠质量因素相关，但与睡眠效率因素无关。
The purpose of this research was to evaluate the factor structure of the Pittsburgh Sleep Quality Index (PSQI) in rheumatoid arthritis (RA). The sample included 107 patients with RA, 88 females and seven males, with an average age of 56.09 years, recruited from the greater Southern California area. Confirmatory factor analysis evaluated single, two- and three-factor models. The single factor solution yielded a poor fit to the data. While the three-factor solution had the best fit, the two-factor solution, comprised of sleep efficiency and perceived sleep quality factors, was optimal because it had very good fit, and acceptable reliability for its individual factors. Clinical indices were consistently correlated with the sleep quality factor, but not with the sleep efficiency factor.
