Insomnia Severity Index (ISI)*

The Insomnia Severity Index* has seven questions. The seven answers are added up to get a total score. The total score is from 0-28. This is used to determine whether or not you are likely to have insomnia and its severity level. 
Remember: No screening survey is absolutely accurate and if you are concerned about your sleep, we recommend that you discuss it with your doctor or call the UT Sleep Disorders Center.
