Thought-shape fusion (TSF) is a cognitive distortion associated with eating disorders (ED). A similar distortion, thought-abandonment fusion (TAbF), is assumed to occur in borderline personality disorder (BPD). In this study the specificity of TSF in participants with anorexia nervosa (AN) and TAbF in participants with BPD was examined. 63 patients completed questionnaires assessing the manifestation of trait-TAbF and trait-TSF, as well as relevant psychopathology. Nonparametric conditional inference trees were used to test for cognitive disorder-specificity. Participants with AN exhibited higher trait-TSF-scores than those with BPD, when participants with BPD and a co-occurring AN were removed. Trait-TSF in participants with AN seemed to be disorder-specific. Participants with BPD and a co-occurring AN had the highest TAbF-scores. The specificity hypothesis could only be partially confirmed for trait-TAbF: while participants with BPD and a co-occurring AN tended to have the highest trait-TAbF scores, high mean values could also be found in participants with AN. The results indicate that TAbF is not specific to BPD, but may also play a role in AN. Both distortions seem to play a role in the maintenance of the respective disorders.
思维形合融合（TSF）是一种与饮食失调（ED）相关的认知扭曲。类似的扭曲，即思维放弃融合（TAbF），被认为发生在边缘型人格障碍（BPD）中。在这项研究中，检查了神经性厌食症（AN）患者中 TSF 的特异性和 BPD 患者中 TAbF 的特异性。63 名患者完成了评估特质-TAbF 和特质-TSF 表现以及相关精神病理学的问卷。非参数条件推理树用于测试认知障碍的特异性。当排除 BPD 患者伴发 AN 时，AN 患者的特质 TSF 评分高于 BPD 患者。AN 患者的特质 TSF 似乎是特定于疾病的。伴发 AN 的 BPD 患者具有最高的 TAbF 评分。特质 TAbF 的特异性假设只能部分得到证实：虽然伴发 AN 的 BPD 患者往往具有最高的特质 TAbF 评分，但也可以在 AN 患者中发现较高的平均值。结果表明，TAbF 不是 BPD 特有的，也可能在 AN 中起作用。这两种扭曲似乎都在维持各自的障碍中发挥作用。
