对社会威胁的偏见性注意与社交焦虑症有关。在暴露疗法期间改变视觉注意力提供了对这种机制的直接测试。我们开发并测试了一个简短的虚拟现实暴露治疗（VRET）协议，使用360°视频和眼动跟踪。参与者（N = 21）被随机分配到标准VRET或VRET +注意力引导训练（AGT）。使用多水平贝叶斯模型来检验（1）是否存在随时间推移的状况效应，以及（2）治疗后凝视模式的变化是否介导了随访时的状况效应。干预对社交焦虑症状有很大的整体影响，AGT增强对观众视觉注意力变化的影响也很大。有微弱的证据对公众演讲的恐惧和弱证据支持中介效应的条件的影响，但这些估计模型先验的强烈影响。综上所述，我们的研究结果表明，注意力可以在VRET内和VRET期间被修改，并且视觉凝视回避的修改可能与社交焦虑的减少有偶然的联系。需要用更大的样本量进行复制。
Biased attention to social threat has been implicated in social anxiety disorder. Modifying visual attention during exposure therapy offers a direct test of this mechanism. We developed and tested a brief virtual reality exposure therapy (VRET) protocol using 360°-video and eye tracking. Participants (N = 21) were randomized to either standard VRET or VRET + attention guidance training (AGT). Multilevel Bayesian models were used to test (1) whether there was an effect of condition over time and (2) whether post-treatment changes in gaze patterns mediated the effect of condition at follow-up. There was a large overall effect of the intervention on symptoms of social anxiety, as well as an effect of the AGT augmentation on changes in visual attention to audience members. There was weak evidence against an effect of condition on fear of public speaking and weak evidence supporting a mediation effect, however these estimates were strongly influenced by model priors. Taken together, our findings suggest that attention can be modified within and during VRET and that modification of visual gaze avoidance may be casually linked to reductions in social anxiety. Replication with a larger sample size is needed.
