Ítem Modelos aditivos y multiplicativos en el análisis de matrices multitrazos - multimétodos de cuestionarios de intereses profesionales(2009-02-18 00:00:00) Ruhel, Jacques; Marivain, ThierryThe psychologist needs the evaluation of the conceptual validity (convergent and discriminant) of psychological constructions, used for describing and explaining the organization of his observations. In this work, we describe two approaches based in latent variables, that can be used for these evaluations. The first one is the first order confirmatory (or restrictive) factor analysis; the second one is the direc´-product model where the traits and the methods take effect. The methods are used on a data matrix multitrait and multimethod take effect. The methods are used on a data matrix multitrait and multimethod obtained on a sample of 189 french high-school students, that responded two questionnaires of professional interests; a discussion of the results follows.Keywords: conceptual validity, multitrait-multimethod matrices, confirmatoty factor analysis, direct- product model, professional interest.
