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 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, and daytime dysfunction. Each item is weighted on a 0–3 interval scale.
This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
The 'Epworth sleepiness scale' (ESS) is also a self-reported questionnaire that measures the general level of sleepiness in a day [49] [50] The patients have to rate specific daily situations by means of a scale going from 0 (would never doze) to 3 (high chance of dozing). [51]
Their study had over 4,000 students in India take a number of tests, in a variety of subjects, at different times throughout the day — some were administered tests shortly after eating, others ...
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 be used in place of a 2-week sleep diary. The questionnaire can be a valid determinate of sleep parameters such as bed time, wake time, sleep latency ...
