与食物相关的焦虑和回避是神经性厌食症的主要特征，也是治疗中最难维持的过程之一。这项研究收集的信息，食物相关的焦虑，包括他们的协会与早期经验的厌恶学习相关的食物，和更广泛的anxiety. MethodsOne一百四十四名神经性厌食症患者从临床服务招募在意大利。他们完成了在线问卷调查，以评估食物相关的焦虑，饮食失调的精神病理学，饮食失调的安全行为和威胁认知，早期经验的厌恶学习相关的食物，和躯体anxiety. ResultsThe经验的食物相关的厌恶学习回忆的大部分样本（87.86%），与负面的心理后果后，吃是最经常报告的（75%）。还报告了与进食后果相关的安全行为和威胁认知（分别为14.29%-87.86%和36.43%-90%，取决于行为/认知）。进食障碍的精神病理学预测躯体焦虑和负面的心理后果后吃，而自我报告的食物焦虑只预测躯体anxiety.ConclusionFindings验证了焦虑为基础的模型神经性厌食症，建立的安全行为，威胁认知，早期厌恶的学习经验，和焦虑的精神病理学的疾病。基于暴露的干预措施有可能针对这些因素，并抑制与食物有关的恐惧。
ObjectiveFood-related anxiety and avoidance are key features of anorexia nervosa, and among the most arduous maintaining processes to address in treatment. This study gathered information on the behavioural and cognitive correlates of food-related anxiety, including their associations with early experiences of aversive learning related to food, and more general anxiety.MethodsOne-hundred and forty-four patients with anorexia nervosa were recruited from clinical services in Italy. They completed online questionnaires to assess food-related anxiety, eating disorder psychopathology, eating disorder safety behaviours and threat cognitions, early experience of aversive learning related to food, and somatic anxiety.ResultsExperiences of food-related aversive learning were recalled by the majority of the sample (87.86%), with negative psychological consequences following eating being the most often reported (75%). Safety behaviours and threat cognitions related to the consequences of eating were also reported (14.29%–87.86%, and 36.43–90% respectively, depending on the behaviour/cognition). Eating disorder psychopathology was predicted by both somatic anxiety and negative psychological consequences following eating, whereas self-reported food anxiety was only predicted by somatic anxiety.ConclusionFindings validate an anxiety-based model of anorexia nervosa which establishes the role of safety behaviours, threat cognitions, early aversive learning experiences, and anxiety in the psychopathology of the illness. Exposure-based interventions have the potential to target these factors, and inhibit food-related fear.
