Epworth Sleepiness Scale


Epworth Sleepiness Scale

A scale, obtained by self-administered questionnaire, that rates an individual’s probability of falling asleep on a scale of increasing probability from 0 to 3 for eight different situations that people experience in their daily lives. A final score of 0–9 is in the normal range; 11–15 is typical of mild to moderate sleep apnoea; a score of 16 and above is associated with severe sleep apnoea and narcolepsy (for the latter of which the Epworth Sleepiness Scale is both highly specific and sensitive). Named after the Epworth Hospital in Melbourne.
