Definition & Meaning
The Pittsburgh Sleep Quality Index (PSQI) is a widely recognized tool designed to measure sleep quality and disturbances over a one-month period. Developed by Joel Carnazzo PsyD, this questionnaire assesses various sleep-related factors, including sleep latency, duration, and disturbances, leading to a comprehensive evaluation of an individual's sleep quality. The PSQI is used in both clinical settings and research to diagnose sleep disorders and guide treatment decisions. The tool's reliability and validity make it a trusted resource for healthcare professionals.
