Social anxiety disorder (SAD) is a specific subtype of anxiety disorder where individuals experience uncomfortable social situations that induce anxious feelings including nervousness and panic. Computer technology has been applied in interventions for many mental health disorders. We aim to understand and explore the use of virtual reality exposure therapy (VRET) to treat adults with SAD. We conducted a literature search using relevant mesh keywords in PubMed and PsycINFO. Six studies met inclusion criteria in our final qualitative synthesis review. Results showed a significant reduction in SAD symptom severity based on primary measures in all studies, suggesting that VRET is an effective option in treating SAD. Studies have shown the success of VRET in formats such as a single-user implementation, one-session treatment, and self-training intervention. In conclusion, VRET is effective in reducing SAD symptoms. The limitations of most studies included a small sample size and weak ecological validity. Future research can examine VRET with a more extensive clinical sample and broader social behaviors.
