The development and use of a new scale, the Epworth sleepiness scale (ESS), is described. This is a simple, self-administered questionnaire which is shown to provide a measurement of the subject's general level of daytime sleepiness. One hundred and eighty adults answered the ESS, including 30 normal men and women as controls and 150 patients with a range of sleep disorders. They rated the chances that they would doze off or fall asleep when in eight different situations commonly encountered in… 

Tables from this paper

Epworth Sleepiness Scale in obstructive sleep apnea syndrome--an underestimated subjective scale.
Daytime sleepiness, snoring, and obstructive sleep apnea. The Epworth Sleepiness Scale.
TLDR
ESS scores significantly distinguished patients with primary snoring from those with obstructive sleep apnea syndrome (OSAS), and ESS scores increased with the severity of OSAS.
The Epworth Sleepiness Scale may not reflect objective measures of sleepiness or sleep apnea
TLDR
The data suggest that the subjectively derived ES cannot be used as a surrogate for the objectively determined Multiple Sleep Latency Test (MSL) or measures of sleep apnea severity.
Correlations among Epworth Sleepiness Scale scores, multiple sleep latency tests and psychological symptoms
TLDR
The aim of this study was to identify factors other than objective sleep tendency associated with scores on the Epworth Sleepiness Scale (ESS) and conclude that the MSLT and the ESS are not interchangeable.
Observation and Interview-based Diurnal Sleepiness Inventory for measurement of sleepiness in older adults
TLDR
The Observation and Interview-based Diurnal Sleepiness Inventory is a suitable measure of sleepiness and is appropriate for usage in clinical care in older adults.
The Epworth Sleepiness Scale in Service Members with Sleep Disorders.
TLDR
Overall, the ESS had poor ability to differentiate sleep disorders in military personnel, and does not help to differentiate OSA from insomnia.
Epworth Sleepiness Scale and sleep studies in patients with obstructive sleep apnea syndrome
TLDR
It is suggested that objective EDS in OSAS is related with fragmentation of sleep, and that several patients are not aware of their EDS.
Clinical utility of the Epworth sleepiness scale
TLDR
Individual ESS scores varied considerably within individual patients, but with classification into either normal or sleepy, the test-retest reliability of the ESS was substantial and in line with other clinical measures including polysomnographic determination of the AHI.

The Stanford Sleepiness Scale (SSS) is a self-rating scale which is used to quantify progressive steps in sleepiness. The present study investigated whether the SSS cross-validates with performance
Determinants of daytime sleepiness in obstructive sleep apnea.
TLDR
The best predictor of the excessive daytime sleepiness (EDS) frequently found inOSAS patients was the nocturnal polygraphic recording of the sleep disturbances and sleep structure anomalies that reflect the brain's overall dysfunction in OSAS.
Daytime alertness in patients with chronic insomnia compared with asymptomatic control subjects.
TLDR
The results are interpreted as supporting the existence of a tendency towards physiological hyperarousal in patients with chronic insomnia, which may be exacerbated by other factors also associated with insomnia.
Predictors of objective level of daytime sleepiness in patients with sleep-related breathing disorders.
TLDR
The hypothesis that sleep fragmentation is an important determinant of daytime sleepiness in patients with apnea is supported.
Relationship of autonomic nervous system activity to daytime sleepiness and prior sleep.
TLDR
The findings suggest that ANS activity is related to daytime sleepiness and to the quality of prior sleep.
Sleep extension in sleepy and alert normals.
TLDR
The sleep extension improved daytime sleepiness differentially in the two groups and the degree of improvement was greater in the sleepy subjects than the alert subjects and the pattern of improvement differed between the groups.
Sleep habits of healthy young adults: use of a sleep questionnaire.
TLDR
In the present study a sleep questionnaire was given to a relatively homogeneous population of fourth-year medical students at Monash University, Melbourne in 1969 and 1970 and the answers given by these students to questions relating to the quality and quantity of their usual sleep are described.
Twenty-four-hour structure of sleepiness in morning and evening persons investigated by ultrashort sleep-wake cycle.
TLDR
There was a significant interaction between type and time of day with respect to amount of sleep: morning types slept significantly more under the attempting sleep condition and showed an earlier rise in nocturnal sleepiness.
Daytime sleepiness, performance, mood, nocturnal sleep: the effect of benzodiazepine and caffeine on their relationship.
TLDR
Objective sleep measures of daytime sleepiness were not significantly related to either performance or mood, but subjects with greater daytimeSleepiness had significantly longer and more efficient nocturnal sleep and neither benzodiazepine or caffeine influenced these relationships.
Excessive daytime somnolence in young men: prevalence and contributing factors.
TLDR
Different possible factors of daytime sleep episodes were investigated, including hours of nocturnal sleep, sleep-wake schedule, sleep difficulties, use of hypnotics, snoring, and occurrence of cataplexy; a strong association was found between these factors and excessive daytime somnolence.
