World Trade Center 9/11 Virtual Reality Clinical Study


We are recruiting individuals with Posttraumatic Stress Disorder related to 9/11 who witnessed the WTC attacks (i.e., who witnessed the planes hit the towers and/or witnessed the towers collapse)


The purpose of this study is to treat symptoms of Posttraumatic stress disorder (PTSD) resulting from 9/11 using traditional treatment combined with the Virtual Reality Therapy program. We will also be examining the effects of using D-Cycloserine (DCS) in conjunction with the virtual reality treatment.


Treatment is offered on an individual basis for 12-14 weekly sessions lasting approximately 75 minutes each. This cognitive-behavioral treatment aims to introduce skills and techniques that will reduce symptoms and improve quality of life. One essential component of the treatment includes describing one's experiences on 9/11. To enhance the ability to retell the experience, participants will be presented with a computerized virtual reality World Trade Center scenario, in which they will see and hear a "virtual environment" through a headset. In addition, participants will be randomly assigned to take either a low dose of D-Cycloserine (DCS; a broad-spectrum antibiotic) or a placebo pill prior to their weekly session to examine the effects of DCS on treatment. Thus treatment incorporates traditional techniques that have been shown to be effective in treating PTSD, with cutting edge technology and pharmacology to enhance the treatment. Treating clinicians are all highly experienced in working with PTSD, civilians and disaster workers.
