OBJECTIVE
The authors' goal was to examine the efficacy of computer-generated (virtual reality) graded exposure in the treatment of acrophobia (fear of heights).
METHOD
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.
RESULTS
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.
CONCLUSIONS
The authors conclude that treatment with virtual reality graded exposure was successful in reducing fear of heights.
目的
作者的目标是检验计算机生成（虚拟现实）分级暴露疗法在治疗恐高症（对高度的恐惧）中的疗效。
方法
20名患有恐高症的大学生被随机分配到虚拟现实分级暴露治疗组（N = 12）或等待名单对照组（N = 8）。17名学生完成了研究。治疗在8周内单独进行。通过治疗前后与暴露于高度相关的焦虑、回避、态度和痛苦测量来评估结果。
结果
在所有测量指标上，完成虚拟现实治疗的学生（N = 10）和等待名单上的学生（N = 7）之间存在显著差异。治疗组在8周后有显著改善，但对照组没有变化。
结论
作者得出结论，虚拟现实分级暴露疗法成功降低了对高度的恐惧。
