Epworth Sleepiness Scale (ESS)
Epworth Sleepiness Scale (ESS)
Please visit this website for more information about the instrument:
Supplemental: Spinal Cord Injury (SCI), Sport-Related Concussion (SRC) Subacute (after 72 hours to 3 months), and Persistent/Chronic (3 months and greater post concussion)
Exploratory: Sport-Related Concussion (SRC) Acute (time of injury until 72 hours)
|Short Description of Instrument||
The Epworth Sleepiness Scale (ESS) was developed in 1991 and is the most widely used subjective scale of daytime somnolence.
As with all subjective scales, participants may not recognize sleepiness, particularly when chronic.
Translations are available in over 20 languages and the Scale can be completed in less than 5 minutes.
See Epworth Sleepiness Scale - Children and Adolescents Version (ESS-CHAD) for children and adolescents aged 5-18.
Rated from 0-24, with high scores indicating worse sleepiness.
General interpretation is 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
Strengths/Weaknesses: The ESS is indicated for studies requiring a subjective measure of 'sleep propensity' (i.e. sleepiness). It has been extensively used in the general population and many health conditions. The ESS has also been used quite extensively in SCI studies. More evidence supporting its psychometric properties in SCI is warranted.
