This module guides you through important screening, assessment questionnaires, and a brief interpretation to help you decide whether an online CBT-I course may suit you. Please read each question carefully, answer honestly, and take note of any recommendations to consult a health professional.

I have been diagnosed with bipolar disorder or have experienced manic or hypomanic episodes.
I have a seizure disorder or a history of seizures.
