Efficacy of virtual reality in reducing fear of public speaking: A systematic review

Abstract

Abstract Public speaking is no doubt one of the most feared mode of oral communication. Such anxiety is often treated through cognitive behavior therapy (CBT). An arising alternative to this treatment is virtual reality exposure therapy (VRET) where user confronts feared stimuli in a controlled 3D environment designed for such purpose. Sense of presence in this medium elicits similar feeling when standing in front of a real audience. Because of this, several studies were conducted to test its effect on individuals suffering from PSA. This paper attempts to look into the undertakings of studies within the last 10 years with the objective of gaining enlightenment on the efficacy of virtual reality in reducing public speaking anxiety. From Google Scholar search engine and online libraries PLOS ONE and ScienceDirect, 14 were short-listed for final review based on the set inclusion/exclusion criteria. Findings of these studies reveal that VRET can be as effective as CBT, and more advantageous in terms of cost-efficiency and manageability. The use of virtual reality is then highly recommended as a tool for treating PSA. It is worth noting that the length of time spent in this therapy is a great factor in its efficacy.
