Epworth Sleepiness Scale^[1]

The Epworth Sleepiness Scale (ESS) is a subjective patient questionnaire that evaluates the extent of daytime sleepiness in everyday situations. Take this questionnaire to see where you rank on the Epworth Sleepiness Scale, and to discuss your results with your doctor.

This questionnaire asks you to rate your likelihood of falling asleep in certain situations you encounter in the course of your day. On the form below, choose the option that best reflects your recent experience. If you haven’t engaged in some of these activities, try to imagine how they would affect you. Answers are rated from a low of zero to a high of three. An answer of zero means you would never fall asleep in this situation, while answering three means it’s very likely that you would.

After completing this questionnaire below click the results button which will tally your results. A score of 10 or more suggests that you might be suffering from excessive daytime sleepiness. You can then print the completed form and take the results to discuss with your doctor.
