Understanding the Pittsburgh Sleep Quality Index (PSQI)
What is the PSQI?
The Pittsburgh Sleep Quality Index (PSQI) is a standardized self-report questionnaire designed to measure sleep quality and disturbances over a 1-month period. Developed by Buysse et al. in 1989, the PSQI has become one of the most widely used tools in sleep research and clinical practice.
Components of the PSQI
The PSQI evaluates seven key components of sleep:
1. Subjective Sleep Quality: How the individual perceives their sleep quality.
2. Sleep Latency: Time taken to fall asleep.
3. Sleep Duration: Total sleep time per night.
4. Sleep Efficiency: Percentage of time in bed spent sleeping.
5. Sleep Disturbances: Factors that interrupt sleep, such as awakening during the night.
6. Use of Sleep Medication: Frequency of sleep medication use.
7. Daytime Dysfunction: Impact of sleep problems on daily activities.
Each component is scored on a scale of 0 to 3, with higher scores indicating poorer sleep quality.

Interpreting PSQI Scores
Score Thresholds
- 0–5: Good sleep quality
- 6–10: Poor sleep quality
- 11–21: Significant sleep disturbances
Clinical Significance of PSQI Scores
Higher scores are associated with greater sleep problems and may indicate underlying sleep disorders such as insomnia, sleep apnea, or restless leg syndrome. The PSQI score helps clinicians decide on further diagnostic testing or intervention strategies.
Limitations and Considerations
While the PSQI provides valuable insights, it should be used alongside other assessments for comprehensive evaluation. Self-reported data may also be subject to bias, and clinical judgment remains essential.
