Introduction
Epworth Sleepiness Scale (ESS) is a simple and widely used self-administered questionnaire to measure daytime sleepiness. It was developed by Dr. Murray W. Johns in 1991 to assess the likelihood of falling asleep in various situations during the day.
The ESS has become a standard tool for assessing subjective daytime sleepiness in research and clinical settings. Here is a general review of the ESS, including its background, administration, interpretation, strengths, and limitations.
Background
The ESS consists of eight situations that people commonly experience during the day, such as sitting and reading, watching TV, and riding in a car. Participants rate their likelihood of falling asleep in each situation on a scale from 0 to 3, with 0 indicating no chance of dozing and 3 indicating a high chance of dozing. The scores are then added together to obtain a total score, which ranges from 0 to 24.
Administration
The ESS is a self-administered questionnaire that takes only a few minutes to complete. Participants are instructed to rate their likelihood of dozing off in each situation based on their usual daytime activities, rather than on how they feel at the time of completing the questionnaire.
Interpretation
The ESS score is a measure of subjective daytime sleepiness. Scores of 10 or higher are considered to be indicative of excessive daytime sleepiness, and scores of 16 or higher suggest a high probability of falling asleep in inappropriate situations. However, the interpretation of ESS scores should be made in conjunction with other clinical information, such as medical history, physical examination, and objective measures of sleepiness.
Strengths
- Simple, quick, and easy-to-administer questionnaire
- Good reliability and validity
- Can be completed by individuals without any medical training
- Useful for screening individuals who may be at risk for sleep disorders
- Can monitor the effectiveness of treatment
- Has been used in numerous studies to assess the effectiveness of interventions for sleep disorders
Conclusion
The ESS is a useful tool for assessing subjective daytime sleepiness in research and clinical settings. It is easy to administer, reliable, and valid, and has been used in numerous studies to assess the effectiveness of interventions for sleep disorders.
However, the ESS has some limitations that should be considered when interpreting its scores.
