Treatment of posttraumatic stress disorder (PTSD) is hindered by limited uptake, early drop-out and non-response. This pilot study aimed to explore the feasibility, acceptability, and usability of a mobile app as part of a blended approach to treating frontline workers experiencing PTSD. A single-group pre-post study was conducted with 10 adult frontline workers (firefighters, police, correctional workers) receiving trauma-focused cognitive-behavioural therapy for PTSD. Participants used an app (Support Base) designed to consolidate session content and encourage independent skills practice. At post-treatment, feasibility was assessed via app usage data and participant feedback, usability via the mHealth App Usability Questionnaire, and acceptability via items from the Mobile Application Rating Scale: user version. Usability ratings were above average and the app received an overall mean rating of 3.4/5. Despite generally positive attitudes towards using technology in therapy, participants had low levels of confidence/experience with wellbeing apps and almost half preferred using the standard treatment workbook. Clinicians highlighted a range of client barriers to app use, including difficulties in clinician/client collaboration. Overall, there was significant pre- to post-treatment improvement in clinical measures of PTSD and depression, but this change cannot be tied to app use. Although Support Base was viewed by participants as usable and acceptable, there were feasibility issues which must be further considered in delivering this form of care. Due to the uncontrolled study design, any additive effects of the app beyond standard clinical treatment could not be assessed. The development of a more integrated blended care model is a potential avenue for future research.
