Abstract

Los test estadísticos se utilizan de forma generalizada como criterio de evaluación de escalas de medida de constructos latentes en organización de empresas y marketing. Sin embargo, la utilización de éstos puede llevar a conclusiones erróneas sobre la validez de las escalas de medida, si no se consideran las divergencias en cuanto al contenido teórico que los conceptos susceptibles de ser medidos poseen. Este trabajo muestra a través de un ejemplo real como, en el caso de los análisis encaminados a estudiar la validez discriminante entre conceptos, existen varios procedimientos estadísticos que ofrecen resultados confrontados. Por tanto, la validez de contenido debe de ser el principal argumento para concluir que dos escalas que miden conceptos dispares, realmente divergen. / There is a widespread use of statistical tests to evaluate measurement scales of latent constructs in the business arena. However, the results of these tests can yield misleading conclusions regarding the validity of measurement scales. Therefore, content validity has to be considered in order to avoid misleading outcomes. Through an empirical example, this paper shows how different statistical tests used to analyse discriminant validity yield ambiguous findings. Consequently, discriminant validity should be theoretically established.
