Summary

The Pittsburgh Sleep Quality Index (PSQI) is a validated clinical tool used to assess sleep quality over the past month. It measures seven components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. Each component scores 0–3; the global score (0–21) distinguishes good sleepers (≤5) from poor sleepers (>5).

How it works

  1. Answer 9 questions covering your typical sleep habits over the past month.
  2. Each answer maps to one of 7 scored components (0 = no difficulty, 3 = severe difficulty).
  3. The calculator sums all 7 component scores into a global PSQI score (0–21).
  4. A global score of 5 or below indicates good sleep quality.
  5. A global score above 5 indicates poor sleep quality — consider discussing with a clinician.
  6. Results are computed entirely in your browser; nothing is stored or sent anywhere.
