已经进行了许多结果研究，以评估虚拟现实在治疗特定恐惧症方面的疗效。然而，大多数研究使用自我报告数据。增加唤醒和信息处理机制的客观措施将是一个有价值的贡献，以验证虚拟现实在治疗焦虑症的有用性。本研究的目的是记录虚拟现实暴露（VRE）对心脏反应和自动处理威胁刺激的影响。28名患有蜘蛛恐惧症的成年人接受了评估，并接受了使用虚拟现实的治疗。一般结果和特定过程的措施包括一组标准化问卷，一个图形化的情绪Stroop任务，行为回避测试和测量参与者的心跳间隔（IBI），而他们正在看一个活的狼蛛。在治疗前后进行评估。重复测量方差分析显示，治疗有积极的影响问卷数据，以及行为回避测试。对图像Stroop任务的分析表明，治疗后蜘蛛相关刺激的信息处理发生了变化，这也表明治疗成功。心理生理学数据也显示治疗后的积极变化，表明焦虑减少。总之，VRE在客观测量和自我报告工具上导致了显著的治疗改善。
Many outcome studies have been conducted to assess the efficacy of virtual reality in the treatment of specific phobias. However, most studies used self-report data. The addition of objective measures of arousal and information processing mechanisms would be a valuable contribution in order to validate the usefulness of virtual reality in the treatment of anxiety disorders. The goal of this study was to document the impact of virtual reality exposure (VRE) on cardiac response and automatic processing of threatening stimuli. Twenty-eight adults suffering from arachnophobia were assessed and received an exposure-based treatment using virtual reality. General outcome and specific processes measures included a battery of standardized questionnaires, a pictorial emotional Stroop task, a behavioral avoidance test and a measure of participants' inter-beat intervals (IBI) while they were looking at a live tarantula. Assessment was conducted before and after treatment. Repeated measures ANOVAs revealed that therapy had a positive impact on questionnaire data, as well as on the behavioral avoidance test. Analyses made on the pictorial Stroop task showed that information processing of spider-related stimuli changed after treatment, which also indicates therapeutic success. Psychophysiological data also showed a positive change after treatment, suggesting a decrease in anxiety. In sum, VRE led to significant therapeutic improvements on objective measures as well as on self-report instruments.
