女性在更年期过渡和绝经后的各个阶段都会出现睡眠质量差的情况，尤其是潮热的时候。由于可用的仪器种类繁多，睡眠测量结果差异很大。匹兹堡睡眠质量指数 (PSQI) 是一种常用的调查问卷，可产生睡眠质量的单一分数。这一单因素结构尚未在文献中得到一致的支持。该分析的目的是确定潮热女性 PSQI 的最佳因子结构。对来自三项随机对照临床试验的 PSQI 基线数据进行了验证性因素分析，这些试验从更年期策略：寻找症状和健康 (MsFLASH) 网络中招募了患有潮热的围绝经期和绝经后女性 (N=849)。比较了几个先验因素模型。一因素和二因素模型不适合数据。包括睡眠效率、感知睡眠质量和每日干扰的三因素模型显示出良好的拟合度；然而，由于身体不适和睡眠药物使用率低，睡眠药物项目被取消。在非裔美国人 (AA) 和白种人子样本中检验了三因素模型，发现两组的情况相似；然而，有两个项目在指标强度方面显示出较小的群体差异。根据 PSQI 测量，患有潮热的中年女性的睡眠质量似乎由三个相关因素组成。组间检测到的微小测量差异具有研究意义，但不需要不同的评分实践。需要进行更多研究来进一步定义睡眠质量及其与健康相关结果的关联。
Women report poor sleep quality during various stages of the menopause transition and post-menopause, especially those with hot flashes. Sleep measurements vary widely due to the copious instruments available. The Pittsburgh Sleep Quality Index (PSQI) is a frequently used questionnaire that produces a single score for sleep quality. This one-factor structure has not received consistent support in the literature. The goal of this analysis was to determine the best factor structure of the PSQI in women with hot flashes. A confirmatory factor analysis was conducted on the PSQI baseline data from three randomized controlled clinical trials enrolling peri- and postmenopausal women with hot flashes (N=849) from the Menopause Strategies: Finding Lasting Answers for Symptoms and Health (MsFLASH) network. Several a priori factor models were compared. One- and two-factor models did not fit the data. A three-factor model comprising Sleep Efficiency, Perceived Sleep Quality, and Daily Disturbance showed good fit; however, the sleep medication item was dropped due to poor fit and low rates of sleep medication use. The three-factor model was examined in African American (AA) and Caucasian subsamples and found to be similar in both groups; however, two items showed small group differences in strength as indicators. Sleep quality in midlife women with hot flashes, as measured by the PSQI, appears to comprise three correlated factors. Minor measurement differences detected between groups are of research interest, but do not necessitate different scoring practices. Additional research is needed to further define sleep quality and its associations with health-related outcomes.
