Background : High-quality debriefing is critical for effective simulation-based education; reliable tools are needed to assess its quality. Such tools must be validated for use with diverse populations, including French-speaking learners, to ensure their applicability across cultural and linguistic contexts. The French version of the Debriefing Experience Scale (DES-FR) was developed to address this need. Methods : A total of 396 French-speaking healthcare students completed the DES-FR. Internal consistency, test-retest reliability, confirmatory factor analysis, and measurement invariance were assessed. Results : The DES-FR showed excellent internal consistency, good to excellent test-retest reliability, and strong structural validity, supporting a four-factor model. Metric invariance was achieved for the Experience scale, while partial invariance was observed for the Importance scale. Conclusions : The DES-FR is a robust instrument with strong psychometric properties, suitable for assessing debriefing quality in simulation-based education among French-speaking healthcare students.
