Athens Insomnia Scale (AIS) — online insomnia test
Mark the answers that describe your sleep, provided the difficulty occurred at least three times a week during the last month.
Interpretation
Each of the 8 items scores 0–3, giving a total of 0–24. The first five items cover night-time sleep (ICD-10 insomnia criterion A) and the last three daytime functioning (criterion C).
- ≥ 6 points — the authors’ cut-off (93% sensitivity, 85% specificity).
- ≥ 8 points — the optimal cut-off in the Polish validation (94% sensitivity, 84% specificity).
The score helps with diagnosis and with tracking treatment, but insomnia is diagnosed by a clinician.
Limitations
- The scale does not distinguish primary insomnia from insomnia secondary to depression, sleep apnoea or restless legs syndrome.
- Symptoms count only if they occurred at least 3 times a week over the last month.
- The scale is copyrighted by Prof. C.R. Soldatos; we reproduce it with attribution for educational purposes.
