Do you have insomnia? Take this quick quiz to determine the severity of your symptoms. It should take you under 5 minutes.

Please note: The Insomnia Severity Index (ISI) is a brief screening tool designed to evaluate insomnia. It was developed by Dr. Charles M. Morin, Professor of Psychology at the Université Laval in Quebec City, Canada, a world leading authority on insomnia and its treatment. The ISI was validated with several hundred patients suffering from insomnia; although it is not a diagnostic tool, it can be used to assess the perceived severity of insomnia and determine the need for treatment.
