Abstract

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.
