The efficacy of individual cognitive-behavioural therapy (CBT) for eating disorders can be assessed by investigating the potential predictors, mediators and moderators of treatment. The present review focused on personality since its crucial role has been emphasized both by research and practice. Sixteen studies were collected, and data were extracted through a highly operationalized coding system. Overall, personality disorders were the most investigated construct; however, their influence was somewhat contradictory. A more cogent result occurred for borderline personality disorder (BPD) when considered as a moderator (not a predictor nor a mediator). Patients with a more disturbed borderline personality benefited to a greater extent from treatments including booster modules on affects, interpersonal relationships and mood intolerance, rather than symptoms exclusively. Nine additional personality dimensions, beyond BPD, were investigated sparsely, and results regarding them were barely indicative in this review. However, some of these dimensions (e.g., affective lability and stimulus-seeking behaviours) could be traced back to BPD, thereby strengthening evidence of the role of borderline disorder as a moderator. Although research on the relationship between personality and eating disorders needs to be increased and methodologically improved, personality, taken as a whole, emerged as a promising variable for enhancing the efficacy of CBT.

人格是饮食失调认知行为疗法的关键吗？回顾

个体认知行为疗法 (CBT) 对进食障碍的疗效可以通过研究治疗的潜在预测因子、调节因子和调节因子来评估。本综述侧重于人格，因为研究和实践都强调了人格的关键作用。收集了 16 项研究，并通过高度可操作的编码系统提取数据。总体而言，人格障碍是研究最多的结构。然而，他们的影响却有些矛盾。当将边缘型人格障碍 (BPD) 视为调节因子（不是预测因子或中介因子）时，会出现更令人信服的结果。边缘人格更受干扰的患者在更大程度上受益于治疗，包括关于情感、人际关系和情绪不耐受的增强模块，而不仅仅是症状。除了 BPD 之外，另外九个人格维度的研究很少，关于它们的结果在本次审查中几乎没有指示性。然而，其中一些维度（例如，情感不稳定性和寻求刺激的行为）可以追溯到 BPD，从而加强了边缘性障碍作为调节剂的作用的证据。尽管需要增加对人格与饮食失调之间关系的研究并在方法上进行改进，但作为一个整体，人格已成为提高 CBT 疗效的一个有希望的变量。情感不稳定性和寻求刺激的行为）可以追溯到 BPD，从而加强了边缘性障碍作为调节剂的作用的证据。尽管需要增加对人格与饮食失调之间关系的研究并在方法上进行改进，但作为一个整体，人格已成为提高 CBT 疗效的一个有希望的变量。情感不稳定性和寻求刺激的行为）可以追溯到 BPD，从而加强了边缘性障碍作为调节剂的作用的证据。尽管需要增加对人格与饮食失调之间关系的研究并在方法上进行改进，但作为一个整体，人格已成为提高 CBT 疗效的一个有希望的变量。
