Outcome Measures
Primary Outcomes (1)
Pittsburgh Sleep Quality Index (PSQI) Total Score
The Pittsburgh Sleep Quality Index (PSQI) is a validated self-reported questionnaire evaluating sleep quality over the past month, covering 7 domains: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. Each domain is scored 0-3, with a total score ranging from 0 to 21; higher scores indicate worse sleep quality. The total PSQI score will be assessed to evaluate changes in participants' sleep status.
