Given the clinical usefulness of the CFQ-BI (Cognitive Fusion Questionnaire-Body Image; the only existing measure to assess the body-image-related cognitive fusion), the present study aimed to confirm its one-factor structure, to verify its measurement invariance between clinical and non-clinical samples, to analyze its internal consistency and sensitivity to detect differences between samples, as well as to explore the incremental and convergent validities of the CFQ-BI scores in Brazilian samples. This was a cross-sectional study, which was conducted in clinical (women with overweight or obesity in treatment for weight loss) and non-clinical samples (women from the general population). The one-factor structure was confirmed showing factorial measurement invariance across clinical and non-clinical samples. The CFQ-BI scores presented an excellent internal consistency, were able to discriminate clinical and non-clinical samples, and were positively associated with binge eating severity, general cognitive fusion, and psychological inflexibility. Furthermore, body-image-related cognitive fusion scores (CFQ-BI) presented incremental validity over a general measure of cognitive fusion in the prediction of binge eating symptoms. This study demonstrated that CFQ-BI is a short scale with reliable and robust scores in Brazilian samples, presenting incremental and convergent validities, measurement invariance, and sensitivity to detect differences between clinical and non-clinical groups of women, enabling comparative studies between them.
鉴于CFQ-BI（身体意象认知融合问卷；唯一现有的评估与身体意象相关的认知融合的测量工具）在临床上的实用性，本研究旨在确认其一因素结构，验证其在临床样本和非临床样本之间的测量不变性，分析其内部一致性和检测样本间差异的敏感性，以及探究CFQ-BI分数在巴西样本中的增量效度和聚合效度。这是一项横断面研究，在临床样本（接受减肥治疗的超重或肥胖女性）和非临床样本（普通人群中的女性）中进行。确认了一因素结构，表明在临床和非临床样本中存在因子测量不变性。CFQ-BI分数具有出色的内部一致性，能够区分临床样本和非临床样本，并且与暴饮暴食严重程度、一般认知融合和心理灵活性呈正相关。此外，在预测暴饮暴食症状方面，与身体意象相关的认知融合分数（CFQ-BI）相对于一般认知融合测量具有增量效度。本研究表明，CFQ-BI是一个简短的量表，在巴西样本中具有可靠且稳健的分数，呈现出增量效度和聚合效度、测量不变性以及检测临床和非临床女性群体间差异的敏感性，从而能够在它们之间进行比较研究。
