厌恶的情绪被认为在维持神经性厌食症患者的限制性饮食中起着关键作用。这项探索性横断面研究探讨了神经性厌食症患者的食物特异性特征和厌恶状态、进食障碍精神病理学、疾病严重程度（体重指数：BMI）以及与虚拟食物的相互作用之间的相关性。在三个虚拟现实（VR）厨房中的一个中暴露于虚拟食物之前，测量了特定于食物的厌恶和饮食失调症状，参与者被随机分配到其中。在VR曝光期间测量食物相互作用（眼睛注视和接触虚拟食物）。在VR曝光后收集食物特定状态厌恶评级。在整个样本中，进食障碍症状与食物特异性特质厌恶呈正相关（rs（68）= 0.45，p < 0.001）。我们还发现，在每个虚拟厨房场景中，食物特定状态厌恶和进食障碍症状之间存在显著关联：仅虚拟厨房（rs（22）= 0.40，p = 0.05），虚拟厨房加宠物（rs（22）= 0.80，p < 0.001），虚拟厨房加化身（rs（20）= 0.78，p < 0.001）。没有显着的相关性，观察特定食物的厌恶措施和食物相关的触摸之间的联系。食物特异性特征厌恶和食物相关的眼睛凝视之间的相关性在不同的场景中不同。目前的实验范式需要改进，以得出明确的结论。食物特异性特征和状态厌恶都与进食障碍的精神病理学相关，因此，有效的策略是必要的，以减轻食物特异性厌恶。
The emotion of disgust is thought to play a critical role in maintaining restrictive eating among individuals with anorexia nervosa. This exploratory cross-sectional study examined correlations between food-specific trait and state disgust, eating disorder psychopathology, illness severity (body mass index: BMI), and interactions with virtual foods in people with anorexia nervosa. Food-specific trait disgust and eating disorder symptoms were measured before exposure to virtual foods in one of three virtual reality (VR) kitchens to which participants were randomly allocated. Food interactions (eye gaze and reaching towards virtual foods) were measured during the VR exposure. Food-specific state disgust ratings were collected after the VR exposure. In the entire sample, eating disorder symptoms correlated positively with food-specific trait disgust (rs (68) = 0.45, p < 0.001). We also found a significant association between food-specific state disgust and eating disorder symptoms in each virtual kitchen scenario: virtual kitchen only (rs (22) = 0.40, p = 0.05), virtual kitchen plus pet (rs (22) = 0.80, p < 0.001), and virtual kitchen plus avatar (rs (20) = 0.78, p < 0.001). No significant correlation was observed for the link between food-specific disgust measures and food-related touch. Correlations between food-specific trait disgust and food-related eye gaze differed across scenarios. The current experimental paradigm needs to be improved to draw firm conclusions. Both food-specific trait and state disgust are associated with eating disorder psychopathology, and therefore, effective strategies are warranted to attenuate food-specific disgust.
