Short Description of Instrument
The Epworth Sleepiness Scale (ESS) was developed in 1991 and is the most widely used subjective scale of daytime somnolence.
As with all subjective scales, participants may not recognize sleepiness, particularly when chronic.
Translations are available in over 20 languages and the Scale can be completed in less than 5 minutes.
Rated from 0–24, with high scores indicating worse sleepiness.
General interpretation is as follows
0–5 Lower Normal Daytime Sleepiness
6–10 Higher Normal Daytime Sleepiness
11–12 Mild Excessive Daytime Sleepiness
13–15 Moderate Excessive Daytime Sleepiness
16–24 Severe Excessive Daytime Sleepiness
