Cognitive Fusion Questionnaire—Body Image: Psychometric Properties and Its Incremental Power in the Prediction of Binge Eating Severity

Abstract

Given the clinical usefulness of the CFQ-BI (Cognitive Fusion Questionnaire -BodyImage; 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 analyse 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 nonclinical 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.

“…Costa Marôco, and Pinto-Gouveia (2017) validated a Portuguese language translation in a general adult sample and in samples with chronic health problems, finding support for invariance across groups. Similarly, Lucena-Santos, Trindade, Oliveira, and Pinto-Gouveia (2017) validated a Brazilian Portuguese version and showed invariance across three samples of Brazilian women (a general sample, a college sample, and a medical sample of women treated for weight concerns). Romero-Moreno, Losada, Fernández-Fernández, Márquez-González, and Gillanders (2014) validated a Spanish language version of the CFQ in a sample of dementia caregivers.…”
