Epworth Sleepiness Scale

The ESS measures a person’s general level of daytime sleepiness, or their average sleep propensity in daily life (ASP). It is a simple questionnaire based on retrospective reports of the likelihood of dozing off or falling asleep in a variety of different situations. The ESS is the most commonly used method for measuring a person’s ASP, used worldwide in many different languages.

The ESS should be used with a clear understanding of what it measures, and what its strengths and limitations are.
