Sleep & Fatigue

Pittsburgh Sleep Quality Index (PSQI Short)

7-component self-report sleep quality index over the past month.

This check is based on the Pittsburgh Sleep Quality Index developed by Buysse and colleagues at the University of Pittsburgh. Our version is a shortened seven-component self-rating that asks about sleep latency, duration, efficiency, disturbances, medication use, daytime dysfunction and overall quality. Scores here are not interchangeable with the full validated PSQI instrument.

1. Sleep latency — How long does it usually take you to fall asleep at night? (Not at all / Very good, Slightly / Fairly good, Moderately / Fairly bad, Severely / Very bad)
2. Sleep duration — How many hours of actual sleep do you get per night? (Not at all / Very good, Slightly / Fairly good, Moderately / Fairly bad, Severely / Very bad)
3. Sleep efficiency — How well do you feel you sleep relative to time in bed? (Not at all / Very good, Slightly / Fairly good, Moderately / Fairly bad, Severely / Very bad)
4. Sleep disturbances — How often does pain, discomfort, or wakings disturb your sleep? (Not at all / Very good, Slightly / Fairly good, Moderately / Fairly bad, Severely / Very bad)
5. Use of sleep medication — How often do you use sleep aids? (Not at all / Very good, Slightly / Fairly good, Moderately / Fairly bad, Severely / Very bad)
6. Daytime dysfunction — How often does sleepiness affect your daily activities? (Not at all / Very good, Slightly / Fairly good, Moderately / Fairly bad, Severely / Very bad)
7. Overall sleep quality — How would you rate your overall sleep quality? (Not at all / Very good, Slightly / Fairly good, Moderately / Fairly bad, Severely / Very bad)
