A sleep study (polysomnography) is required to know if someone has sleep apnea. This test will also determine the severity of sleep apnea, if present. Physicians and insurance companies sometimes use a variety of screening tools to help determine if someone is at risk for this disorder. One such tool is the Epworth sleepiness questionnaire, which is provided below. If your score is greater than 8, it is likely that you have sleep apnea. Scores less than 9 are inconclusive, and do not successfully predict whether or not someone has sleep apnea.
Using the scale of numbers provided below (0 to 3), rate how likely you are to become sleepy and doze during each circumstance described in the examples. Answer the questions using what has happened to you recently (during the last 6 months, for example). Even if you have not done the things in the examples recently, think about each of them and try to conclude how each would effect you.
0 = no chance of dozing
1 = slight chance of dozing
2 = moderate chance of dozing
3 = high chance of dozing
