Methods
For a detailed description of the methodology see the trial protocol (Dell et al., Participants underwent a pre-treatment baseline assessment (T1) including a clinical interview and a self-report booklet. Immediately following T1 assessment, eligible participants were randomly allocated in a 1:1 ratio to SPE or MPE therapy. Randomisation occurred using two components – randomisation to SPE or MPE, and then randomisation to a therapist to deliver the intervention. Assessors (blinded to condition) conducted follow-up assessments at 4 weeks post-treatment commencement (T2), 12 weeks post-treatment commencement (T3), and 12 months post-treatment commencement (T4).The Australian Defence Human Research Ethics Committee and Department of Veterans' Affairs Human Research Ethics Committee approved the protocol (now known as the Departments of Defence and Veterans' Affairs Human Research Ethics Committee), see Dell et al.
