Researchers administered the Epworth Sleepiness Scale (ESS) to 620 consecutive individuals 16 years or older who presented to the Department of Motor Vehicles in Madison, WI, for various reasons related to driving. The ESS is an 8-item questionnaire where each question is answered with a score from 0 (would never doze) to 3 (high chance of dozing), yielding a total between 0 (minimum) and 24 (maximum sleepiness). Questions ask the tendency to fall asleep during the following circumstances: (1) sitting and reading, (2) watching TV, (3) sitting inactive in a public place, (4) as a passenger in a car for 1 hour without a break, (5) lying down in the afternoon, (6) sitting and talking to someone, (7) sitting quietly after lunch, and (8) in a car while stopped for a few minutes in traffic. The data confirm that daytime sleepiness is not only common in the general population, but also among drivers.
