The Epworth Sleepiness Scale has been used to compare the sensitivity and specificity of other similar measurements of sleep quality. [8] [9] The Pittsburgh Sleep Quality Index is a related scoring tool of sleep quality. Both scores are internally highly reproducible. [10] The test has limitations that can affect the test's accuracy.
One is the Epworth Sleepiness Scale (ESS) which grades the results of a questionnaire with eight questions referring to situations encountered in daily life. The ESS generates a numerical score from zero (0) to 24 where a score of ten [10] or higher may indicate that the person should consult a specialist in sleep medicine for further evaluation.
The Epworth Sleepiness Scale measures general sleep propensity and asks the patient to rate their chances of dozing off in eight different situations. The Stanford Sleepiness Scale asks the patient to note their perception of sleepiness by using a seven-point test. The Sleep Timing Questionnaire is a 10-minute self-administration test that can ...
The mortality is higher for women. [66] Some studies report that it is more frequent among the Hispanic and African American population than among the white population. [66] If studied carefully in a sleep lab by polysomnography (formal "sleep study"), it is believed that approximately 1 in 5 American adults would have at least mild OSA. [174]
Professor Jim Horne, director of Loughborough University's Sleep Research Centre, explains that "for women, poor sleep is strongly associated with high levels of psychological distress and greater ...
Consisting of 19 items, the PSQI measures several different aspects of sleep, offering seven component scores and one composite score. The component scores consist of subjective sleep quality, sleep latency (i.e., how long it takes to fall asleep), sleep duration, habitual sleep efficiency (i.e., the percentage of time in bed that one is asleep), sleep disturbances, use of sleeping medication ...
Men and women ages 20-45 may qualify for a sleep deprivation study that consists of four weeks of screening and a 10-day hospital stay. Other requirements of this study may include personal health ...
The Stanford Sleepiness Scale (SSS), developed by William C. Dement and colleagues in 1972, is a one-item self-report questionnaire measuring levels of sleepiness throughout the day. The scale has been validated for adult populations [ 1 ] and is generally used to track overall alertness at each hour of the day.
