 The study found that virtual reality exposure-based cognitive behavioral therapy, VRE-CBT, is more effective than waitlist and as effective as regular cognitive behavioral therapy, CBT, in treating more severe anxiety disorders, excluding specific phobias and sub-threshold anxiety disorders. The results suggest that VRE-CBT may be a promising alternative to CBT for patients with more severe anxiety disorders. However, higher quality randomized controlled trials are needed to verify the robustness of these findings.
