Although several questionnaires have been developed to measure mindfulness, the Five Facets Mindfulness Questionnaire (FFMQ), [Baer et al., 2006. Using self-report assessment methods to explore facets of mindfulness. Assessment, 13, 27-45] is currently one of the most empiricallybased scale assessing mindfulness. Objective. - The present study was designed to: (1) test the psychometric properties and (2) explore the structural validation of the French version of the FFMQ. Method. - Two hundred and fourteen participants were tested using the French version of the FFMQ. Results. - Using confirmatory factor analysis, the results showed the French version of the FFMQ has good psychometric properties and a structural validity similar to the initial version. Conclusion. - This adaptation constituted a validated mindfulness measure for French-speaking clinicians as well as researchers.
