Abstract: Background: The Cognitive Fusion Questionnaire (CFQ) is a self-report questionnaire that assesses the extent to which individuals are psychologically entangled with, and dominated by the form/ content of their thoughts. The aim of this study was to replicate the factor structure of CFQ in osteoarticular disease, diabetes mellitus, obesity, depressive disorder and normative population. It further examined the factorial invariance of the CFQ across these five groups. Method: Data from 299 participants (N General Population= 67, N Osteoarticular Disease= 73, N Diabetes Mellitus= 47, N Depressive Disorder= 45, N Obesity= 60) were subjected to Confirmatory Factorial Analysis (CFA) to replicate the structural model of CFQ dimensionality. Results: CFA supported an one-factor structure with good internal consistency and construct related validity. The one-factor solution was also supported by a second independent data set, which showed a configural, strict measurement and structural invariance of the one-factor solution proposed. Multigroup Confirmatory Factorial Analysis showed the configural invariance, strict measurement invariance and also structural invariance of CFQ across the five groups under study. Conclusions: The unidimensional model have both similar meanings and the same structure, but the measurement model across the groups was not the same. The study provides the first approach to CFQ to Portuguese population, as a reliable tool of general cognitive fusion. Furthermore, results indicated that CFQ has a coherent structure across multiple samples and clinical utility, as it discriminate individuals with psychological distress from those who do not.
