Sleep Quality Index Calculator
Calculate comprehensive sleep quality score using Pittsburgh Sleep Quality Index methodology
About this calculator
The Sleep Quality Index Calculator uses the validated Pittsburgh Sleep Quality Index (PSQI) methodology to assess your overall sleep quality through a comprehensive scoring system. This scientifically-backed tool evaluates seven key components including sleep duration, sleep latency, sleep efficiency, sleep disturbances, use of sleep medications, daytime dysfunction, and subjective sleep quality. By analyzing these factors, it provides a standardized score that helps identify potential sleep disorders and guide improvements to your sleep hygiene and overall health.
How to use
Answer questions about your sleep patterns over the past month, including bedtime, wake time, sleep latency, and sleep disturbances. Rate your sleep quality and any daytime impacts on the provided scales. The calculator will automatically compute your PSQI score and provide interpretation based on established clinical guidelines.
Frequently asked questions
What is a good PSQI score?
Scores range from 0-21, with lower being better. A score of 5 or below indicates good sleep quality, while scores above 5 suggest poor sleep quality requiring attention.
How often should I use this calculator?
Use it monthly or when experiencing sleep changes. The PSQI assesses sleep patterns over the past month, so more frequent use won't provide meaningful results.
Can this calculator diagnose sleep disorders?
No, this is a screening tool only. While it identifies poor sleep quality, consult a healthcare professional for proper diagnosis and treatment of sleep disorders.
