ABSTRACT

Background:

Canadian public safety personnel (PSP) experience high rates of mental health disorders and face many barriers to treatment. Internet-delivered cognitive behavioural therapy (ICBT) overcomes many such barriers and is effective for treating depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms.

Objective:

The current study was designed to fill a gap in the literature regarding the use of ICBT tailored specifically for PSP. We examined the effectiveness of a tailored ICBT program for treating depression, anxiety, and PTSD symptoms among PSP in the province of Saskatchewan.

Methods:

We employed a longitudinal single-group open trial design (n = 83) with outcome measures administered at screening and eight weeks. Data was collected between December 5, 2019 and September 11, 2020. Primary outcomes included changes in depression, anxiety, and PTSD symptoms. Secondary outcomes included changes in functional impairment and symptoms of panic, social anxiety, and anger, as well as treatment satisfaction, working alliance, and program usage patterns.

Results:

Clients reported large symptom reductions on measures of depression and anxiety, as well as moderate reductions on measures of PTSD and secondary symptoms, except for social anxiety. Most clients who reported symptoms above clinical cut-offs on measures of depression, anxiety, and PTSD during screening experienced clinically significant symptom reductions. Results suggested good engagement, treatment satisfaction, and working alliance.

Conclusions:

Tailored, transdiagnostic ICBT demonstrated promising outcomes as a treatment for depression, anxiety, and PTSD among Saskatchewan PSP and warrants further investigation. Clinical Trial: clinicaltrials.gov (NCT04127032).
