Résumé

The present study sought to examine the psychometric properties of the French and German versions of the Physical Self-Concept Questionnaire for Elementary School Children – Revised (PSCQ-C-R). A sample of 519 children participated in this study. Of those, 197 were French-Canadian and 322 were German. Results support the factor validity and reliability of PSCQ-C-R across the overall sample and the French-Canadian and German samples. Subsequent analyses not only supported the weak, partial strong, and strict invariance of the PSCQ-C-R across samples, but also showed significant latent mean differences across samples. Moreover, analyses revealed a lack of differential item functioning as a function of age, body mass index, and sex between samples, as well as latent mean differences (that were invariant between samples) as a function of children’s age, body mass index, and sex. Finally, analyses confirmed the measurement invariance of the PSCQ-C-R over a nine-month period in the German sample.
