简要总结
This study randomly assigned 114 participants with significant fear of heights to one of three conditions: a) a single session of virtual reality exposure; b) a single session of in vivo exposure; or c) a control condition. The aim of this study was to compare the efficacy of virtual reality exposure to the efficacy of in vivo exposure or no exposure for participants with significant fear of heights.

结局指标
主要结局
Acrophobia Questionnaire (AQ)
时间窗: 1-Week Post-Treatment (Controlling for Immediate Post-Treatment Scores)
Participants completed the anxiety subscale of the AQ, a 20-item questionnaire that assesses self-reported anxiety related to acrophobia. Scores for the subscale are summed, and totals range from 0 to 120, with higher scores indicating greater anxiety.
Heights Interpretation Questionnaire (HIQ)
时间窗: 1-Week Post-Treatment (Controlling for Immediate Post-Treatment Scores)
Participants completed the HIQ, a 16-item questionnaire that assesses self-reported interpretations of an imagined experience of heights. Items are summed scored, and totals ranged from 16 to 80, with higher scores indicating greater height fear-relevant interpretation bias.
Behavioral Approach Task (BAT)
时间窗: 1-Week Post-Treatment (Controlling for Immediate Post-Treatment Scores)
Participants walked up a staircase until they reach the highest level they can complete, while stopping to look over the ledge toward the floor at each landing. During each BAT, fear response was assessed behaviorally (highest step reached) and subjectively (self reported levels of fear).
