Athens Insomnia Scale, AIS

Test scores

AIS scores 0-5 generally indicate no or minimal insomnia symptoms, while scores ≥ 6 signal the probable presence of an insomnia disorder.

The higher the score above 6, the more severe the insomnia is considered: for instance, a score in the tens or higher implies substantial sleep impairment affecting both night-time sleep and daytime well-being.

Clinicians may use the degree of elevation in the AIS score to gauge whether insomnia is mild, moderate, or severe, even though the AIS itself is often used primarily with the single cutoff to screen for insomnia. A score of 0 would indicate normal sleep with no complaints, and intermediate scores (e.g. 6-12 vs. 13-24) can give a sense of moderate vs. severe insomnia, respectively, with all eight domains being increasingly affected as the score rises.
