Bryant RA, Kenny L, Rawson N, et al. - Cognitive behavior therapy (CBT) is supported as possibly valuable for treating PTSD in emergency service personnel using either prolonged or brief periods of reliving the trauma memory; the benefits can last for at least 2 years after treatment.

• Randomization of 100 emergency service personnel with PTSD was done to CBT-Long (CBTL), CBT-Brief (CBTB), or WaitList (WL).

• In both CBT conditions, 12 weekly individual sessions were involved that comprised education, CBT skills building, imaginal exposure, in vivo exposure, cognitive restructuring, and relapse prevention.

• At the 2 year follow-up, CBTL and CBTB did not differ in PTSD severity.

• Very large effect sizes were recorded for CBTL and CBTB from baseline to 2-year follow-up
