摘要进食障碍(ED)是一组与进食行为异常相关的精神障碍，症状复杂多变，各个亚型间常出现诊断交叉，共病率高，医学治疗常存在困难，严重影响患者的生活质量。以跨诊断视角理解ED为治疗提供了新思路。按照认知行为治疗理论，心理认知发展是跨诊断ED的重要维持机制。核心信念作为最深层次的心理认知，在ED发展和维持中起着重要作用。大量研究发现，各个亚型的ED患者中，与自我相关的核心信念如体形体重、成就/价值和控制感，与世界或他人相关的核心信念如不可爱和被抛弃，既影响进食相关症状，也在共病层面发挥作用。本文首次重点对ED患者跨诊断的核心信念进行梳理，进一步厘清跨诊断核心信念与ED症状间的联系，以期更好地了解、预防、诊治ED，促进康复，减少复发。

abstractsEating disorders(ED) are a group of psychiatric disorders related to abnormal eating behaviors, with complex and variable symptoms, frequent crossover of diagnoses among various subtypes, high comorbidity rates, and often difficulties in medical treatment, which seriously affect the quality of life of patients. Understanding ED from a transdiagnostic perspective provides new ideas for treatment. According to the theory of cognitive behavioral therapy, psychological cognitive development is an important maintenance mechanism for the transdiagnosis of ED. Core beliefs, as the deepest level of psychological cognition, play an important role in the development and maintenance of ED. A large number of studies have found that among patients with various subtypes of ED, the core beliefs related to the self involve body shape and weight, achievement/worth, sense of control, and the core beliefs related to the world/others involve unloveability and abandonment influence both eating-related symptoms and comorbidity levels. For the first time, this paper focuses on sorting out the transdiagnostic core beliefs of patients with ED and further clarifying the relationship between transdiagnostic core beliefs and ED symptoms, in order to better understand, prevent and treat ED, then promote recovery and reduce relapse.
