“Buying into thoughts”: French validation of the Cognitive Fusion Questionnaire

摘要

This research reports the psychometric properties of a French version of the Cognitive Fusion Questionnaire (CFQ). Cognitive fusion is one of the central concepts of Acceptance and Commitment Therapy (ACT), a form of cognitive and behavioural therapy (CBT). Cognitive fusion is defined as the excessive dominance of verbal or cognitive events on behavior, relative to other sources of behavioural influence. Cognitive fusion is characterized by entanglement in thinking, taking thoughts literally and viewing them as highly believable or factually accurate. Despite the relevance of cognitive fusion, very few instruments are available for the clinician and researcher, and none are yet available in French. Hence, the purpose of this paper is to translate and validate the CFQ among different samples of French-speaking individuals. Results across three samples (e.g. 2 undergraduate samples, one chronic pain sample from the community) show good support of the CFQ’s factor structure, internal consistency, as well as concurrent and convergent validity. The results are discussed in terms of the potential uses of the CFQ for research and clinical purposes.
