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.
The SWAI consists of 59 items that provide six subscale scores: excessive daytime sleepiness, nocturnal sleep, ability to relax, energy level, social desirability, and psychic distress. [1] Each item is rated on a 1 to 9 semicontinuous Likert type scale from "always" to "never", based on the previous seven days. [ 1 ]
Adolescent sleep worsens with age. Specifically, longitudinal research demonstrates that sleep duration shortens during the transition from high school to college. [6] Additionally, sleep efficiency (the amount of time spent asleep when in bed) decreased during this transition. Day-to-day variability in sleep duration increased during this ...

The following standardized tests are designed and/or administered by state education agencies and/or local school districts in order to measure academic achievement across multiple grade levels in elementary, middle and senior high school, as well as for high school graduation examinations to measure proficiency for high school graduation.
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.
Sleep efficiency (SE) is the ratio between the time a person spends asleep, and the total time dedicated to sleep (i.e. both sleeping and attempting to fall asleep or fall back asleep). It is given as a percentage. [1] SE of 80% or more is considered normal/healthy with most young healthy adults displaying SE above 90%.
In narcolepsy, the Epworth Sleepiness Scale has both a high specificity (100%) and sensitivity (93.5%). [7] 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.
