Pittsburgh Sleep Quality Index (PSQI)

The Pittsburgh Sleep Quality Index (PSQI) is a questionnaire used by healthcare professionals to assess a person's sleep quality over the past month. It asks about various aspects of sleep, such as how long it takes to fall asleep, how often sleep disturbances occur, and overall sleep satisfaction. The responses are scored to provide a single index that indicates whether someone has good or poor sleep quality. This helps identify sleep problems and guides treatment or lifestyle changes to improve sleep health.
