Abstract Trough the “cross modality matching” approach this research examines the perceived intensity of verbal qualifiers used in agreement scales. Also, the effect on perceived intensity resulting from the scaling context in itself (i.e. number of response categories and the chosen verbal qualifiers) is investigated. Results show a low amount of inter-individual variability between subjects concerning the perceived intensity of verbal qualifiers. A category scale with five response alternatives is least prone to context effects and the use of supplementary extreme answer categories on the left and the right ends of the scale does not improve the metric properties of the scale. L'usage d'échelles est une méthode courante dans le domaine des sciences sociales. Le but de cette expérimentation était de déterminer l'influence sur les réponses des sujets, de l'utilisation de descripteurs verbaux sur une échelle graphique. La tâche des sujets consistait à définir l'intensité de sept descripteurs par estimation numérique et par production graphique d'un trait. Les descripteurs ont été présentés tels quels et dans le contexte d'une échelle à cinq, six ou sept catégories. Afin d'étudier ces relations, nous avons utilisé la technique de d'appariement intermodal. Les résultats montrent qu'une échelle comportant cinq catégories possède les meilleures propriétés psychométriques et que les catégories extrêmes n'apportent aucune valeur supplémentaire à l'échelle.
