The IMPACT trial is comparing a novel, transdiagnostic psychological intervention for PTSD known as the Unified Protocol against Prolonged Exposure therapy, the gold standard in PTSD treatment.
The IMPACT trial is currently funded to provide treatment to veterans and first responders residing in Victoria. For other treatment trials for members from the general community, please see our link to the BDNF trial here.
Unified Protocol therapy has promise as an effective treatment for those with PTSD by helping individuals build skills in emotion regulation to better manage the emotional impacts of trauma. Prolonged Exposure is well established as a treatment for supporting people with PTSD by helping individuals process their traumatic memories and reclaim their lives.
