Read your nights and your days together
The Athens Insomnia Scale (AIS) is an eight-item self-report measure based on the ICD-10 criteria for insomnia. Five items cover getting to sleep, waking during the night, waking early, sleep duration and sleep quality; three cover daytime mood, functioning and sleepiness. This page uses an English translation of the CareOps Korean version and asks about difficulties experienced at least three times a week during the past month.
Reading your results
The total ranges from 0 to 24, and the screen shows sleep at night and daytime functioning separately. The authors’ 2003 study proposed a total of 6 or higher as the screening threshold; the ranges above it match those reported in a 2020 study of adults in Japan. A few restless nights differ from sleep difficulty that continues for more than a month, so consider how long it has lasted and how it affects your days. If you snore heavily, stop breathing during sleep, feel very sleepy in the daytime, or the difficulty continues beyond a month, ask a clinician to look into the cause.
A question to reflect on
For one week, note roughly when you went to bed, fell asleep, woke during the night and got up. Add what you did while lying awake, plus naps, caffeine and alcohol. This makes it easier to see which conditions change from night to night.
