In Israel, civilians are a frequent target of terrorist suicide bombers such as attacks on civilians riding on public buses. After experiencing terrorist attacks, the survivors may develop post traumatic stress disorder (PTSD).
Naomi Josman and her collaborators are studying how virtual reality can be an effective treatment of PTSD. In the following lines, they present an abstract from a forthcoming manuscript by Freedman, SA, Hoffman HG, Garcia-Palacios A, Weiss PL, Avitzour S, and Josman N: “Prolonged Exposure and Virtual Reality enhanced imaginal exposure for PTSD following a Terrorist Bulldozer Attack: A Case Study” (in press), CyberPsychology and Behavior.
Post Traumatic Stress Disorder or PTSD: is a sever and ongoing emotional reaction that may occur following a traumatic event such as serious injury or threat of injury or death. The symptoms of PTSD can include reexperiencing the original trauma with flashbacks or nightmares, avoiding stimuli associated with the trauma, difficulty falling asleep and anger.
Clinician-Administered PTSD Scale or CAPS: is a structured interview that is used for diagnosing and measuring the severity of PTSD. It contains separate ratings for the frequency and intensity of each symptom, which can be summed to create a severity score for each symptom.
This study provided first-time evidence for the efficacy of Virtual Reality Exposure (VRE) treatment in treating Post Traumatic Stress Disorders (PTSD) triggered by an Israeli terrorist attack. In the present case study virtual reality was used to augment imaginal exposure in a protocol based on Prolonged Exposure (PE) (Foa, et al., 2005).
Traumatic memories of childhood abuse and traumatic memories of the bulldozer terrorist attack were treated using imaginal exposure while the patient was in the virtual environment (BusWorld). The patient showed large post-treatment reductions in PTSD symptoms and his Clinician Administered PTSD Scale (CAPS) scores dropped from 79 pre-treatment to zero immediately post-treatment and CAPS was still at zero six months later.
