思想形态融合（Thought-shape fusion，简称TSF）描述的是一种经历，即在考虑吃致肥/禁忌食品后，对体重/体型、肥胖感觉、体重增加的感知以及道德错误的印象产生明显的担忧。本研究旨在评估简短版的TSF特质问卷（TSF）。样本包括315名健康对照妇女，244名患有临床和阈下进食障碍的妇女，113名患有混合精神障碍的妇女（混合）。采用探索性因子分析和后续验证性因子分析对TSF问卷的因子结构进行检验。问卷区分概念量表和临床影响量表。然而，缺乏测量不变性是指在因子负荷、阈值和残差方面组间存在显著差异，这对跨组有效性提出了质疑。结果表明，这一概念在三组中有不同的理解，是指问卷主要适用于出现饮食失调症状的个体。
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.
