Due to COVID-19 measures, the Phoenix Australia Traumatic Stress Clinic has temporarily suspended face-to-face appointments. Presently, recruitment for the IMPACT trial is open for treatment delivered via videoconferencing (available to Victoria residents only at this stage). We welcome expressions of interest for face-to-face treatment in the meantime.
This 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.
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.
Due to significant expression of interest in the IMPACT trial, we currently have a waitlist for this trial. We are in the process of building capacity to meet these demands, however there will be delays in entering the trial and starting treatment for eligible participants. Once you register your interest with us we will record your interest and be in touch with you as soon as possible to discuss the trial and explain the next steps. Please also continue to monitor our website for trial updates.
