Epworth Sleepiness Scale (ESS)[1]

The ESS is a subjective patient questionnaire that evaluates the extent of daytime sleepiness in everyday situations. This questionnaire asks patients to rate their likelihood of falling asleep in certain situations they encounter during the course of their day. Answers are rated from zero to three. An answer of zero means the patient would never fall asleep in this situation, while answering three means it’s very likely that the patient would fall asleep in this situation. The results are then tallied to give a final score.

Key:

  • 0 = would never doze
  • 1 = slight chance of dozing
  • 2 = moderate chance of dozing
  • 3 = high chance of dozing
Situation Chance of Dozing
