Epworth Sleepiness Scale

The Epworth Sleepiness Scale (below) was developed by researchers in Australia and is widely used by sleep professionals around the world to measure sleep deprivation.

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. If you have not done some of these things recently, think about how they have affected you in the past.

**Note: We assume no liability for outcomes of this test, and you by using this test, assume all responsibility contained herein. If you may have sleep apnea, please contact a qualified health care provider.

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
