This study presents the validation of a French version of the Career Adapt-Abilities Scale in four
Francophone countries. The aim was to re-analyze the item selection and then compare this
newly developed French-language form with the international form 2.0. Exploratory factor
analysis was used as a tool for item selection, and confirmatory factor analysis (CFA) verified
the structure of the CAAS French-language form. Measurement equivalence across the four
countries was tested using multi-group CFA. Adults and adolescents (N=1,707) participated from
Switzerland, Belgium, Luxembourg, and France. Items chosen for the final version of the CAAS
French-language form are different to those in the CAAS international form 2.0 and provide an
improvement in terms of reliability. The factor structure is replicable across country, age, and
gender. Strong evidence for metric invariance and partial evidence for scalar invariance of the
CAAS French-language form across countries is given. The CAAS French-language and CAAS
international form 2.0 can be used in a combined form of 31 items. The CAAS French-language
form will certainly be interesting for practitioners using interventions based on the life design
paradigm or aiming at increasing career adapt-ability.
