虚拟现实暴露疗法已被提议作为一种可行的替代方案来治疗焦虑症，包括社交焦虑症。治疗师可以从广泛控制在虚拟暴露中引发焦虑的刺激中受益。本研究研究了两种刺激控制：社会对话情境，以及人与虚拟角色之间的对话反馈反应(积极或消极)。在第一项研究中，16名参与者被暴露在三种虚拟现实场景中：中立虚拟世界、相亲场景和工作面试场景。结果显示，这三个虚拟场景在自我报告的焦虑水平和心率方面存在显著差异。在第二项研究中，24名参与者被暴露在虚拟环境中的求职面试场景中，虚拟角色的积极对话反馈反应与消极对话反馈反应之间的比例在运行中系统地变化。结果发现，在对话中，更积极的对话反馈会导致较少的自我报告焦虑、较低的心率和较长的回答时间，而虚拟角色的较负面对话反馈会导致相反的结果。在8种对话条件下，一方面对话应激源比率与SUD评分、心率和音频长度的平均值之间的相关关系分别为r(6) = 0.91，p = 0.002；r(6) = 0.76，p = 0.028；r(6) = −0.94，p = 0.001。此外，研究发现，暴露前报告的预期焦虑越多，自我报告的焦虑越多，在虚拟暴露期间回答的时间越短。这些结果表明，虚拟环境中的社交对话可以被有效地操纵以达到治疗目的。
Virtual reality exposure therapy has been proposed as a viable alternative in the treatment of anxiety disorders, including social anxiety disorder. Therapists could benefit from extensive control of anxiety eliciting stimuli during virtual exposure. Two stimuli controls are studied in this study: the social dialogue situation, and the dialogue feedback responses (negative or positive) between a human and a virtual character. In the first study, 16 participants were exposed in three virtual reality scenarios: a neutral virtual world, blind date scenario, and job interview scenario. Results showed a significant difference between the three virtual scenarios in the level of self-reported anxiety and heart rate. In the second study, 24 participants were exposed to a job interview scenario in a virtual environment where the ratio between negative and positive dialogue feedback responses of a virtual character was systematically varied on-the-fly. Results yielded that within a dialogue the more positive dialogue feedback resulted in less self-reported anxiety, lower heart rate, and longer answers, while more negative dialogue feedback of the virtual character resulted in the opposite. The correlations between on the one hand the dialogue stressor ratio and on the other hand the means of SUD score, heart rate and audio length in the eight dialogue conditions showed a strong relationship: r(6) = 0.91, p = 0.002; r(6) = 0.76, p = 0.028 and r(6) = −0.94, p = 0.001 respectively. Furthermore, more anticipatory anxiety reported before exposure was found to coincide with more self-reported anxiety, and shorter answers during the virtual exposure. These results demonstrate that social dialogues in a virtual environment can be effectively manipulated for therapeutic purposes.
