Thought-shape fusion (TSF) describes the experience of marked concerns about body weight/shape, feelings of fatness, the perception of weight gain, and the impression of moral wrongdoing after thinking about eating fattening/forbidden foods. This study sets out to evaluate the short version of the TSF trait questionnaire (TSF). The sample consists of 315 healthy control women, 244 women with clinical and subthreshold eating disorders, and 113 women with mixed mental disorders (mixed). The factor structure of the TSF questionnaire was examined using exploratory and subsequent confirmatory factor analyses. The questionnaire distinguishes between a Concept scale and a Clinical Impact scale. However, a lack of measurement invariances refers to significant differences between groups in terms of factor loadings, thresholds, and residuals, which questions cross-group validity. Results indicate that the concept is understood differently in the 3 groups and refers to the suitability of the questionnaire primarily for individuals presenting with symptoms of eating disorders.
思维-体型融合（TSF）描述的是在想到食用易胖/禁食食物后，对体重/体型的显著担忧、肥胖感、体重增加的认知以及道德错误感的体验。本研究旨在评估TSF特质问卷（TSF）的简短版本。样本包括315名健康对照女性、244名患有临床和阈下饮食失调的女性以及113名患有混合精神障碍的女性（混合组）。使用探索性和后续验证性因素分析对TSF问卷的因素结构进行了检验。该问卷区分了一个概念量表和一个临床影响量表。然而，缺乏测量不变性指的是不同组在因素负荷、阈值和残差方面存在显著差异，这对跨组效度提出了质疑。结果表明，这一概念在三组中的理解不同，并且该问卷主要适用于有饮食失调症状的个体。
