Abstract

Objective: Cognitively oriented therapies, first-line treatment for eating disorders (EDs), still show room for improvement in treatment retention and outcomes. Despite the development of additional cognitive models and therapies, few studies examine the relationship between traditional and third-wave cognitive targets in EDs. The study explores the relationship between irrational beliefs (IBs) and metacognitions and their relationship with ED psychopathology and cognitive reappraisal in ED outpatients. Method: Seventy-seven patients (mean age 27.49 ± 12.28 years) were assessed with The Attitudes and Beliefs Scale-ABS-2, Meta-cognitions Questionnaire-MCQ-65, Eating Disorder Inventory 3-EDI-3, Eating Attitudes Test-EAT-40, Emotion Regulation Questionnaire-ERQ. Results: Correlational analyses showed that IBs and metacognitions significantly correlated with each other. Metacognitions partially mediated the relationship between IBs and ED-related general psychological maladjustment and completely mediated the relationship between IBs and ED symptom severity. Cognitive reappraisal was predicted only by IBs and metacognitions were not significant mediators. Conclusions: While IBs are sufficient in explaining ED-related psychopathology and reduced use of cognitive reappraisal, a potential integration of metacognitions about need to control thoughts in CBT models for EDs may offer incremental validity given their contribution to ED severity. Treatment implications include targeting metacognitions concerning need to control thoughts, as a potential maintenance mechanism of ED symptomatology through cognitive restructuring.

摘要

目的：以认知为导向的疗法，即饮食失调（ED）的一线治疗，仍然显示出在治疗保留和疗效方面仍有改善的空间。尽管开发了其他认知模型和疗法，但很少有研究检查ED中传统和第三波认知目标之间的关系。该研究探讨了非理性信念（IBs）与元认知之间的关系，以及它们与ED门诊患者的ED心理病理学和认知重新评估之间的关系。方法：采用态度和信念量表-ABS-2，元认知问卷-MCQ-65，饮食失调量表3-EDI-3，饮食态度测验-EAT对77例患者（平均年龄27.49±12.28岁）进行了评估。 -40，情绪调节问卷-ERQ。结果：相关分析表明，IB和元认知彼此之间显着相关。元认知部分介导了IBs与ED相关的一般心理失调之间的关系，而完全介导了IBs与ED症状严重程度之间的关系。认知重新评估仅由IB预测，而元认知不是重要的中介。结论：尽管IB足以解释ED相关的精神病理学并减少了对认知再评估的使用，但鉴于ED对ED严重性的贡献，潜在的元认知整合可能需要增加CBT模型中控制思想的元认知。治疗的意义包括针对与控制思想有关的元认知，这是通过认知重构来维持ED症状的潜在机制。
