ESS
Epworth Sleepiness Scale
Purpose : Measure of a subject's usual level of daytime sleepiness or average sleep propensity.
The ESS asks people to rate their usual chances of dozing off or falling asleep in 8 different situations or activities that most people engage in as part of their daily lives, although not necessarily every day.
Admin time : 5 min.
User Friendly : High
Administered by : self or GP
Content : The client self-rates on how likely it is that he/she would doze in eight different situations. Scoring of the answers is 0-3, with 0 being “would never doze” and 3 being “high chance of dozing”. A sum of 10 or more from the eight individual scores reflects above normal daytime sleepiness and need for further evaluation.
In general ESS scores can be interpreted as follows:
0-5 Lower Normal Daytime Sleepiness
6-10 Higher Normal Daytime Sleepiness
11-12 Mild Excessive Daytime Sleepiness
13-15 Moderate Excessive Daytime Sleepiness
16-24 Severe Excessive Daytime Sleepiness

Epworth Sleepiness Scale
Advantages:
-
Quick and easy to administer
-
The psychometric properties of the ESS have been investigated widely
Limitations:
-
Because ESS item-scores are based on subjective reports, they can be influenced by the same sources of bias and inaccuracy as any other such reports. The ESS should not be used in isolation in circumstances where the scores could determine outcomes with potential legal implications, such as granting or withholding a driver’s license. Confirmatory evidence of ‘excessive daytime sleepiness’ or an increased risk of a drowsy road-crash should be sought from other sources too.
-
The ESS does not usually enable accurate predictions to be made of a person’s level of drowsiness, and hence their crash-risk, when driving a vehicle at some particular time. However, there may be an exception to this among people with very high ESS scores (>15), whose ASP (average sleep propensity) is very high under most circumstances.
-
The ESS does not distinguish which factors, or which sleep disorders, have caused any particular level of ASP. The ESS is not a diagnostic tool by itself. Nor does it assess other aspects of a person’s sleep habits, for which other methods are available.
-
The ESS is not suitable for use among people with serious cognitive impairment. Nor is it suitable for measuring rapid changes in sleep propensity over periods of hours, eg. to demonstrate the short-term sedative effects of a drug, or to assess the circadian rhythm of sleep propensity.
Accuracy :
Sensitivity (93.5%) and specificity (100%) with a cut-off score > 10. (Johns MW,2001)
