Participants

Participants were recruited from a state-wide department in Australia comprising corrective and welfare service workers, with high rates of occupational trauma exposure. All frontline workers were eligible to participate, regardless of PTSD diagnosis or treatment experience, in order to enrich the data collected regarding the non-clinical aspects of the app (e.g. language, engagement and acceptability), to more accurately simulate treatment-naive patients who had not previously encountered therapy concepts, and to avoid potential confidentiality issues arising from the workshop format. The partner organisation promoted workshop sessions by posting recruitment flyers/advertisements in the workplace and/or online (e.g. via social media channels, email newsletters).
