对食物的厌恶情绪和进食的后果是神经性厌食症的核心。暴露疗法可以有效地减少焦虑和对恐惧刺激的回避。基于抑制性学习框架，本研究探讨了诱导社会支持或积极情绪以增强单次虚拟食物暴露对神经性厌食症患者食物相关焦虑的影响的可行性。基线条件），（2）虚拟食物暴露加上积极情绪诱导（即，积极情绪条件），或（3）虚拟食物暴露加上社会支持（即，社会支持条件）。他们在接触虚拟食物之前和之后完成了对虚拟食物的焦虑，一般焦虑，积极情绪，社会支持和饥饿的自我报告评估。在虚拟现实exposure.ResultsPatients的眼睛注视和触摸对食物的数量被记录在积极的情绪条件下，对虚拟食物的焦虑水平较低，与基线条件相比[F（2,141）= 4.36，p = 0.015;中等效应量]。在基线条件下，他们也更频繁地接触食物。DiscussionVirtual food exposure enhanced by positive mood induction seems a practical approach to strengthen the impact of food exposure in anorexia nervosa.Public Significance这项研究有助于了解如何支持神经性厌食症患者克服食物周围的恐惧和焦虑。虚拟现实使患者能够将自己暴露在困难的情况下（例如，厨房里有各种卡路里含量的食物），同时体验积极的刺激，如一个充满爱心和善良的宠物或支持性的化身。
ObjectiveAversive emotions toward food and the consequences of eating are at the core of anorexia nervosa. Exposure therapy is effective to reduce anxiety and avoidance toward feared stimuli. Based on the inhibitory learning framework, this study examined the feasibility to induce social support or positive mood to enhance the impact of a single session virtual food exposure on food‐related anxiety in anorexia nervosa.MethodOne hundred and forty‐five patients were randomized to: (1) virtual food exposure (i.e., baseline condition), (2) virtual food exposure plus positive mood induction (i.e., positive mood condition), or (3) virtual food exposure plus social support (i.e., social support condition). They completed self‐report assessments of anxiety toward virtual foods, general anxiety, positive mood, social support, and hunger, before and after virtual food exposure. Number of eye gazes and touches toward foods were recorded during the virtual reality exposure.ResultsPatients had lower levels of anxiety toward virtual foods in the positive mood condition, compared to the baseline condition [F(2,141)= 4.36,p= .015; medium effect size]. They also touched food items more often in the baseline condition. No other significant changes were found.DiscussionVirtual food exposure enhanced by positive mood induction seems a feasible approach to strengthen the impact of food exposure in anorexia nervosa.Public SignificanceThis research contributes to the understanding of how patients with anorexia nervosa can be supported to overcome fear and anxiety around food. Virtual reality enables patients to expose themselves to difficult situations (e.g., kitchen with foods of various calorie contents) while experiencing positive stimuli, such as a loving and kind pet or a supportive avatar.
