Cancer patients frequently report sleep problems. The Pittsburgh Sleep Quality Index (PSQI) is a 19-item instrument for assessing sleep problems. The main objective of this study was to analyze the usefulness of the PSQI in oncological research.
A sample of 1,733 cancer patients with mixed diagnoses were included. In addition to the PSQI, the following questionnaires were adopted: the Insomnia Severity Index (ISI), the Jenkins Sleep Scale (JSS) and the sleep scale of the EORTC QLQ-SURV100.
The internal consistency of the PSQI was α = 0.79. Of the PSQI subscales, the subjective sleep quality correlated most strongly with the other sleep instruments ( between 0.68 and 0.77). In total, 69.2% of the sample were poor sleepers; the effect size of the difference between the PSQI total scores of the patients and a general population sample was = 0.83. Female patients experienced more sleep problems than male patients ( = -0.49), and younger patients (<60 years) reported more sleep problems than older patients (≥60 years) ( = 0.21).
The PSQI can be recommended for use in clinical practice since its sub-dimensions provide detailed information on the sleep situation of cancer patients.
癌症患者经常报告存在睡眠问题。匹兹堡睡眠质量指数（PSQI）是一种用于评估睡眠问题的包含19个条目的工具。本研究的主要目的是分析PSQI在肿瘤学研究中的有用性。
纳入了1733例诊断混合的癌症患者样本。除PSQI外，还采用了以下问卷：失眠严重程度指数（ISI）、詹金斯睡眠量表（JSS）和欧洲癌症研究与治疗组织生活质量问卷-生存100（EORTC QLQ-SURV100）的睡眠量表。
PSQI的内部一致性为α = 0.79。在PSQI各子量表中，主观睡眠质量与其他睡眠工具的相关性最强（在0.68至0.77之间）。总体而言，69.2%的样本睡眠质量差；患者PSQI总分与一般人群样本之间差异的效应大小为 = 0.83。女性患者比男性患者经历更多的睡眠问题（ = -0.49），年轻患者（<60岁）比老年患者（≥60岁）报告更多的睡眠问题（ = 0.21）。
PSQI可推荐用于临床实践，因为其子维度提供了关于癌症患者睡眠状况的详细信息。
