PSQI Sleep Archive Room | Decoding Your Hidden Late-Night Killer

I. What Is the PSQI Test?

The Pittsburgh Sleep Quality Index (PSQI) is the 'gold standard' for measuring sleep quality in psychiatry and clinical psychology. It does not focus only on 'how long you slept', but rather, over the past month, on assessing yoursubjective sleep quality, sleep latency, sleep efficiency and daytime dysfunction.

II. Good Sleep Is Not Just 'Falling Asleep'

A healthy sleep profile is usually made up of the following positive indicators:

• Sleep-onset efficiency:Being able to fall asleep within 30 minutes after turning off the lights.
• Complete structure:Having a cyclical rhythm of deep sleep, light sleep and REM sleep, with few awakenings in between.
• Daytime alertness:Feeling refreshed after waking, and not feeling irresistible drowsiness during important meetings or studying.
• Steady breathing:No severe snoring or sleep apnea, and the body fully recovering at night.

III. The Observation Dimensions of This Test

This test is a scenario-based adaptation based on the core principles of the PSQI, with 15 questions covering five key coordinates:

• Sleep-onset resistance:Monitoring your biological clock and adaptability to the environment.
• Continuity and stability:Assessing the frequency of nighttime awakenings and the psychological or physical triggers behind them.
• Breathing and physical symptoms:Focusing on the physical interference of coughing, breath-holding or pain with sleep.
• Medication and aid dependence:Examining your psychological or physiological need for sleep-inducing substances.
• Daytime depletion:Observing the 'long-tail effect' of low-quality sleep on your daytime mood and energy.

IV. How Do You Get the Most Accurate 'Profile'?

Please recallthe past monthwhen making your choices. Sleep is strongly influenced by the environment and short-term stress; an occasional sleepless night does not represent your long-term profile, so please answer based on the average.
