The Argentinian version of the cognitive fusion questionnaire: Psychometric properties and the role of cognitive fusion as a predictor of pathological worry

The Cognitive Fusion Questionnaire (CFQ) consists in an instrument used to measure cognitive fusion. Cognitive fusion can be described as a core process in the psychopathology model of Acceptance and Commitment Therapy (ACT). The purpose of this study was to adapt the CFQ for the Argentinian population, to validate it through a confirmatory factor analysis together with the analysis of its psychometric properties in a local community sample, and to look into the role cognitive fusion plays as a predictor of pathological worry. Three hundred and thirty-three adult participants filled out not only the Argentinian adaptation of the questionnaire (CFQ-VA) but also measures that assessed psychological inflexibility, worry, rumination, mindfulness and psychological well-being. The results indicate that the CFQ’s one-factor structure was confirmed. The instrument showed adequate internal consistency, good temporal stability, and significant associations in the expected directions with relevant selected constructs indicating adequate criterion validity. Also, cognitive fusion emerged as a good predictor of worry. In conclusion, the findings confirm that the Argentinian adaptation of the CFQ presents solid psychometric properties.
