The Pittsburgh Sleep Quality Index (PSQI) is a widely used, evidence-based tool that measures sleep quality and disturbances over a one-month period. It assesses multiple domains including sleep duration, latency, efficiency, disturbances, medication use, and daytime dysfunction. The PSQI helps identify poor sleep quality and supports clinical decision-making, monitoring, and personalized sleep health interventions.
Please answer all questions based on your sleep over the past month.
