Using the ISI Questionnaire
The ISI questionnaire is a screening assessment tool designed to evaluate insomnia. After completion, you should gain an understanding of your insomnia's severity. If insomnia is bothering you, we recommend that you complete the questionnaire and request a full report from us, then provide to your family doctor for further consultation.
