Pittsburgh Sleep Quality Index (PSQI) Scoring System

01 January 1970 0 1K Report

The Pittsburgh Sleep Quality Index (PSQI) scoring system assesses sleep quality over a one-month period. It consists of 19 self-rated items grouped into seven components:

Subjective Sleep Quality

Sleep Latency (time taken to fall asleep)

Sleep Duration

Sleep Efficiency (time asleep vs. time in bed)

Sleep Disturbances

Use of Sleep Medication

Daytime Dysfunction

Each component is scored from 0 (no difficulty) to 3 (severe difficulty).
The component scores are summed to yield a global score ranging from 0 to 21.
A total score >5 indicates poor sleep quality.
