The Epworth Sleepiness Scale is widely used in the field of sleep medicine as a subjective measure of a

patient’s sleepiness. The test is a list of eight situations in which you rate your tendency to become sleepy

on a scale of 0, no chance of dozing, to 3, high chance of dozing. When you finish the test, add up the

values of your responses. Your total score is based on a scale of 0 to 24. The scale estimates whether you

are experiencing excessive sleepiness that possibly requires medical attention.

How Sleepy Are You?

How likely are you to doze off or fall asleep in the following situations? You should rate your chances of

dozing off, not just feeling tired. Even if you have not done some of these things recently try to determine

how they would have affected you. For each situation, decide whether or not you would have:

• No chance of dozing =0

• Slight chance of dozing =1

• Moderate chance of dozing =2

• High chance of dozing =3

Select the number corresponding to your choice below each situation.
