Abstract

Background: Interventions targeting core characteristics of eating disorders (EDs) can effectively alleviate symptoms. However, it remains unclear whether these characteristics exhibit cultural specificity within the Chinese population. This study combines exploratory graph analysis (EGA) and network analysis to identify key psychological characteristics in Chinese patients with EDs.

Methods: The psychological characteristics of 1,001 patients with EDs were assessed using the Eating Disorder Inventory-1 (EDI-1). Nineteen representative items were selected and categorized into different dimensions through EGA. Network analysis was then performed to identify key psychological characteristics by determining central and bridge nodes.

Results: In addition to the "ED-specific" and "Non-specific" categories, an unexpected category, "Perfectionism," was identified. Across these three categories, four key psychological characteristics were highlighted: "terrified of gaining weight," "guilty after overeating," "worry that feelings will get out of control," and "must do things perfectly."

Conclusion: Beyond drive for thinness, perfectionism and emotional regulation difficulties may represent key psychological characteristics among Chinese individuals with EDs. These findings could help inform the development of culturally tailored treatment strategies for EDs in China.

识别中国饮食失调患者的主要心理特征:探索性图和网络分析。
背景:针对进食障碍(EDs)核心特征的干预措施可以有效缓解症状。然而,尚不清楚这些特征是否在中国人群中表现出文化特异性。本研究结合探索性图分析(EGA)和网络分析来识别中国急诊科患者的主要心理特征。方法:采用进食障碍量表-1 (edi1)对1001例急症患者的心理特征进行评估。选取19个具有代表性的项目,通过EGA进行不同维度的分类。然后进行网络分析,通过确定中心节点和桥节点来确定关键的心理特征。结果:除了“ed特异性”和“非特异性”类别外,还发现了一个意想不到的类别,“完美主义”。在这三个类别中,有四个关键的心理特征被强调:“害怕体重增加”、“暴饮暴食后感到内疚”、“担心情绪失控”和“必须把事情做得完美”。结论:除了追求苗条之外,完美主义和情绪调节困难可能是中国ed患者的主要心理特征。这些发现可能有助于为中国急诊科量身定制的治疗策略的发展提供信息。
