Internet-Delivered Cognitive Behaviour Therapy for PTSD Among Public Safety Personnel

This study evaluates two Internet-delivered cognitive behavioural therapy (ICBT) interventions: one for symptoms of posttraumatic stress disorder (PTSD) and one for symptoms of anxiety, depression, and PTSD. Both interventions have been tailored for Canadian public safety personnel (PSP). Outcomes of interest include preference for disorder-specific or transdiagnostic care, engagement with the interventions, changes in symptoms and functioning, and strengths and limitations of implementing ICBT with Canadian PSP.
