What ESS score indicates excessive sleepiness?

ESS scores 0–10 are normal, 11–12 slight, 13–15 moderate, and 16–24 severe excessive daytime sleepiness. Scores >10 warrant further investigation for sleep disorders such as obstructive sleep apnea or narcolepsy.

How is the ESS different from PSQI?

The PSQI assesses sleep quality and disturbance, while ESS specifically measures daytime sleepiness. They assess complementary dimensions and are often used together in sleep disorder evaluation.

Epworth Sleepiness Scale (ESS)

Quantify daytime sleepiness using the Epworth Sleepiness Scale. Rate likelihood of dozing in 8 daily situations (0–3 each) for a total of 0–24; scores >10 indicate excessive daytime sleepiness.

How It Works

Quantify daytime sleepiness using the Epworth Sleepiness Scale. Rate likelihood of dozing in 8 daily situations (0–3 each) for a total of 0–24; scores >10 indicate excessive daytime sleepiness

Each component has a specific meaning:

Epworth Sleepiness Scale — The epworth sleepiness scale recorded for the scenario being assessed.

Note: Interpret the ess score result against the thresholds and context described above.

How to Use

Enter the Epworth Sleepiness Scale for the scenario you are assessing. Quantify daytime sleepiness using the Epworth Sleepiness Scale. Rate likelihood of dozing in 8 daily situations (0–3 each) for a total of 0–24; scores >10 indicate excessive daytime sleepiness. Use the ess score result to inform your calculation.
