Effectiveness of computer-generated (virtual reality) graded exposure in the treatment of acrophobia.

Abstract

The authors' goal was to examine the efficacy of computer-generated (virtual reality) graded exposure in the treatment of acrophobia (fear of heights). Twenty college students with acrophobia were randomly assigned to virtual reality graded exposure treatment (N = 12) or to a waiting-list comparison group (N = 8). Seventeen students completed the study. Sessions were conducted individually over 8 weeks. Outcome was assessed by using measures of anxiety, avoidance, attitudes, and distress associated with exposure to heights before and after treatment. Significant differences between the students who completed the virtual reality treatment (N = 10) and those on the waiting list (N = 7) were found on all measures. The treatment group was significantly improved after 8 weeks, but the comparison group was unchanged. The authors conclude that treatment with virtual reality graded exposure was successful in reducing fear of heights.
