Previous outcome studies on virtual reality and SAD have focused on people suffering from fear of public speaking and not full blown SAD. In this study, 45 adults receiving a DSM-IV-TR diagnostic of social anxiety were randomly assigned to traditional CBT treatment (with in vivo exposure), CBT-VR combined treatment, or a waiting list. Results show significant reduction of anxiety on all questionnaires as well as statistically significant interactions between both treatment groups and the waiting list. © 2010 The Interactive Media Institute and IOS Press.
