MARTINEZ-GARCIA, JOSÉ ANTONIO  e  MARTINEZ-CARO, LAURA. Discriminant Validity as a Scale Evaluation Criterion Theory or Statistics?. Univ. Psychol. [online]. 2009, vol.8, n.1, pp.27-36. ISSN 1657-9267.

Discriminant validity is one of the usual criteria for evaluating measurement scales that define latent constructs in social sciences. This article shows how different statistical procedures frequently used for accomplishing this aim can yield misleading results. Authors recommend a theoretical judgement about divergence among scales that are manifestation of latent concepts. Therefore, content validity represents a robust condition against certain covariance statistical based analysis.
