Post-Traumatic Stress Disorder (PTSD) occurs as a response to an acute traumatic event or an extreme stressor. Symptoms include fear, helplessness, hyperarousal, re-experiencing of the event, and avoidance of reminders of the event for at least one month. PTSD can be treated with pharmacological and psychological interventions such as cognitive behavioural therapy (CBT). CBT delivered through the Internet (iCBT) may mitigate barriers to accessing face-to-face CBT such as geographical distance or cost of treatment.

CADTH completed a review of the clinical effectiveness, cost-effectiveness, patients’ preferences and experiences, as well as the ethical and implementation implications of the use of iCBT for the treatment of PTSD.
