ABSTRACT={In this article, we show that structure validity is an essential step in the psychometric validation of subjective measurement scales, the partial credit model is used to study the structure validity. We take as an example, the psychometric validation of the GOHAI scale (General Oral Health Assessment Index) for the general French population. The partial credit model verifies the unidimensionality of the GOHAI scale.}}
