The Epworth Sleepiness Scale (ESS) is a scale intended to measure daytime sleepiness that is measured by use of a very short questionnaire. This can be helpful in diagnosing sleep disorders. It was introduced in 1991 by Dr Murray Johns of Epworth Hospital in Melbourne, Australia.
The ESS score (the sum of 8 item scores, 0-3) can range from 0 to 24. The higher the ESS score, the higher that personâs average sleep propensity in daily life (ASP), or their âdaytime sleepinessâ. The questionnaire takes no more than 2 or 3 minutes to answer. It is available in many different languages. The 1997 version of the ESS is the standard version that can be used by most adults.
