    Abstract

    In a recent review of various physical self-concept instruments, Marsh and Cheng (in press) noted that the very short 12-item version of the French Physical Self-Inventory (PSI-VS) represents an important contribution to applied research but that further research was needed to investigate the robustness of its psychometric properties in new and diversified samples. The present study was designed to answer these questions based on a sample of 1103 normally achieving French adolescents. The results show that the PSI-VS measurement model is quite robust and fully invariant across subgroups of students formed according to gender, weight, age and ethnicity. The results also confirm the convergent validity and scale score reliability of the PSI-VS subscales.
