| Pittsburgh Sleep Quality Index (PSQI) | Change from baseline PSQI at 8 weeks | The Pittsburgh Sleep Quality Index (PSQI) is a self-report tool used to assess sleep quality and disturbances. It consists of 19 items covering seven components: sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, daytime dysfunction, and use of sleep medications. Each component is scored from 0 to 3, with higher scores indicating worse sleep quality. The total score ranges from 0 to 21, where a score of 5 or higher suggests poor sleep quality. The PSQI is widely used in clinical and research settings to evaluate sleep health. |
