Abstract

Although emergency service personnel experience markedly elevated the rates of post-traumatic stress disorder (PTSD), there are no rigorously conducted trials for PTSD in this population.

One hundred emergency service personnel with PTSD were randomised to either immediate CBT-L, CBT-B or wait-list (WL). Following post-treatment assessment, WL participants were randomised to an active treatment. Participants randomised to CBT-L or CBT-B were assessed at baseline, post-treatment and at 6-month follow-up. Both CBT conditions involved 12 weekly individual sessions comprising education, CBT skills building, imaginal exposure, in vivo exposure, cognitive restructuring and relapse prevention. Imaginal exposure occurred for 40 min per session in CBT-L and for 10 min in CBT-B. At post-treatment, participants in WL had smaller reductions in PTSD severity (Clinician Administered PTSD Scale), depression, maladaptive appraisals about oneself and the world, and smaller improvements on psychological and social quality of l...Continue Reading
