About this trial

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.

Treatments tested in this trial

  • PSP PTSD Course

    Behavioral

    A tailored ICBT intervention designed to treat symptoms of PTSD will be delivered to public safety personnel. Clients will be offered once a week support, but support can be increased to twice a week support if PSP request extra support. The intervention is designed to be completed in 8 weeks, but clients will be able to extend their treatment by an additional 8 weeks (i.e., up to 16 weeks in total).

The intervention is designed to be completed in 8 weeks, but clients will be able to extend their treatment by an additional 8 weeks (i.e., up to 16 weeks in total).
