Epworth sleepiness scale
From Wikipedia, the free encyclopedia
The Epworth sleepiness scale is a questionnaire intended to measure daytime sleepiness. This can be helpful in diagnosing sleep disorders. It was introduced in 1991 by Dr Murray Johns of Epworth Hospital in Melbourne, Australia.[1]

[edit] The instrument
How likely are you to doze off or fall asleep in the following situations, in contrast to feeling just tired? This refers to your usual way of life in recent times. Even if you have not done some of these things recently try to work out how they would have affected you.[1]
Use the following scale to choose the most appropriate number for each situation:
- 0 = no chance of dozing
- 1 = slight chance of dozing
- 2 = moderate chance of dozing
- 3 = high chance of dozing
| Situation | Chance Of Dozing |
|---|---|
| Sitting and reading | |
| Watching TV | |
| Sitting inactive in a public place (e.g a theater or a meeting) | |
| As a passenger in a car for an hour without a break | |
| Lying down to rest in the afternoon when circumstances permit | |
| Sitting and talking to someone | |
| Sitting quietly after a lunch without alcohol | |
| In a car, while stopped for a few minutes in traffic |
[edit] Interpretation
The score obtained by adding the numbers leads to a total:[1]
- 0 - 9 - average score, normal population
- 10 - 24 - sleep specialist advice recommended
The Epworth Sleepiness Scale has been validated primarily in obstructive sleep apnea. It is used to measure excessive daytime sleepiness, and is repeated after the administration of treatment (e.g. CPAP) to document improvement of symptoms.[2] The Pittsburgh Sleep Quality Index is a related scoring tool of sleep quality. Both scores are internally highly reproducible.[3]
