Research on VR Therapy

In this article they stated that there was not a lot " quantitative meta- analysis that enhances understanding of the variability and clinical significance of anxiety reduction outcomes after VRET. Searches of electronic databases yielded 52 studies, and of these, 21 studies (300 subjects) met inclusion criteria."

They stated that "exposure therapy is effective for reducing negative affective symptoms. Empirical data from research assessing the efficacy of VRET on affective outcomes have been increasingly emerging over the last 10 years as VR systems have become less costly, more available and generally more usable."
The results was that VRET "appears effective from a clinical psychology standpoint but the results are limited because there isn't enough research and testing done.

With the cost of VR headsets going down there is a potential increase in use of VR for in-vio exposure therapy. It offers a more realistic approach than imagining your fear.
