匹兹堡睡眠质量指数 (PSQI) 广泛用于评估临床和非临床环境中的主观睡眠质量。尽管通常对 PSQI 进行评分以提供单一睡眠质量因素，但最近的两项研究表明，多因素评分方法可能更合适。因此，本研究调查了 364 名 18 至 59 岁澳大利亚成年人的 PSQI 维度和因子结构。结果表明，二因素和三因素评分模型在统计上优于单因素模型。这些结果补充了最近的发现，并表明对与多个因素相关的 PSQI 进行评分可以促进对社会上日益常见的睡眠问题的评估。
The Pittsburgh Sleep Quality Index (PSQI) is widely used to assess subjective sleep quality in clinical and non-clinical settings. Although the PSQI is routinely scored to provide a single sleep quality factor, two recent studies suggest that multiple factor scoring methods could be more appropriate. As a consequence, the present study investigated for the dimensionality and factor structure of the PSQI in 364 Australian adults aged 18 to 59 years. The results demonstrate that two factor and three factor scoring models were favored statistically over the single factor model. These results add to recent findings and suggest that scoring the PSQI in relation to multiple factors could facilitate the assessment of sleep problems, which are increasingly common in society.
