Une nouvelle évaluation de l'échelle de mesure du leadership d'opinion publiée par Ben Miled et Le Louarn (1994) est pro-posée. Quatre échantillons d'individus ayant chacun rempli l'échelle pour trois catégories de produit différentes ont été utilisés, soit au total 660 individus et 12 catégories de produit. Les distributions des scores contredisent d'une part l'hypothèse d'un leader généralisé. D'autre part, une structure à deux dimensions latentes s'ajuste mieux aux données qu'une structure unidimensionnelle, ceci pour toutes les catégories de produit. Enfin, le très fort lien entre le leadership d'opinion et l'expertise dans la catégorie de produit montre une faible validité discriminante de l'échelle et suggère une relecture complète du concept.
