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. Even if you have not done some of these things recently try to work out how they would have affected you. 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
How likely are you to doze off or fall asleep in the following situations?
This refers to normal activity during the past several months.
