Thought-shape fusion (TSF) describes the experience of body-related cognitive distortions associated with eating disorder (ED) pathology. In the laboratory TSF has been activated by thoughts about fattening/forbidden foods and thin ideals. This study aims at validating a questionnaire to assess the trait susceptibility to TSF (i.e., body-related cognitive distortions) associated with the imagination of thin ideals, and developing an adapted version of the original TSF trait questionnaire, the (TSF-B). Healthy control women (HC, = 317) and women diagnosed with subthreshold and clinical EDs ( = 243) completed an online-questionnaire. The factor structure of the TSF-B questionnaire was examined using exploratory (EFA) and subsequent confirmatory factor analysis (CFA). EFA pointed to a two-factor solution, confirmed by CFA. Subscale 1 was named , containing five items referring to the imagination of female thin ideals. Subscale 2 was named , with seven items about pursuing/abandoning attempts to reach one's own thin ideal. The total scale and both subscales showed good convergent validity, excellent reliability, and good ability to discriminate between individuals with subthreshold/clinical EDs and HCs. Results indicate that cognitive distortions are also related to the imagination of thin ideals, and are associated with ED pathology. With two subscales, the TSF-B trait questionnaire appropriately measures this construct. Future studies should clarify whether TSF-B is predictive for the development and course of EDs. Assessing cognitive distortions with the TSF-B questionnaire could improve understanding of EDs and stimulate the development of cognitively oriented interventions.

思维-体型融合（TSF）描述了与饮食失调（ED）病理相关的身体相关认知扭曲的体验。在实验室中，TSF已通过对增肥/禁食食物和瘦身理想的思考而被激活。本研究旨在验证一份问卷，以评估与瘦身理想想象相关的TSF特质易感性（即身体相关认知扭曲），并开发原始TSF特质问卷的改编版，即TSF-B。健康对照女性（HC，n = 317）和被诊断为阈下和临床ED的女性（n = 243）完成了一份在线问卷。使用探索性因素分析（EFA）和后续验证性因素分析（CFA）对TSF-B问卷的因素结构进行了检验。EFA指向一个双因素解决方案，CFA予以证实。分量表1被命名为“理想体型想象”，包含五个与女性瘦身理想想象相关的项目。分量表2被命名为“追求/放弃尝试达到自身瘦身理想”，有七个关于此方面的项目。总量表和两个分量表均显示出良好的收敛效度、出色的信度，以及在区分阈下/临床ED个体和HC个体方面的良好能力。结果表明，认知扭曲也与瘦身理想的想象有关，且与ED病理相关。通过两个分量表，TSF-B特质问卷能够恰当地测量这一结构。未来的研究应阐明TSF-B是否能预测ED的发展和病程。使用TSF-B问卷评估认知扭曲可能会增进对ED的理解，并促进认知导向干预措施的发展。
