Psychometric validation of the French adaptation of the Teenage Executive Functioning Inventory (TEXI) among adolescents

Executive functioning plays a central role in adolescents’ emotional and behavioral regulation, yet validated French-language measures remain limited. This study evaluated the psychometric properties of the French Teen Executive Functioning Inventory (TEXI) in a community sample of Canadian adolescents (N = 601). Factorial structure was examined using confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM). Convergent validity was assessed through associations with reward sensitivity, impulsivity, and internalizing symptoms. Results supported the expected two-factor structure, with ESEM providing the best model fit. Convergent validity analyses revealed theoretically coherent patterns: inhibition difficulties were strongly associated with reward sensitivity (β = .70, p < .001) and impulsivity (β = .55, p < .001), whereas working memory difficulties showed weaker and differentiated associations once internalizing symptoms were controlled. Overall, findings support the reliability and validity of the French TEXI and its usefulness for screening executive functioning difficulties in French-speaking adolescents.
