Abstract

In recent years, a new Italian standardization was conducted for Raven’s Progressive colored Matrices with samples from different regions of Italy, but with no Sardinian children. The population of Sardinia represents a peculiar group in the Italian population for specific history, for specific genetic bases and for epidemiological differences for various diseases. The present contribution aims to verify the extendibility of Raven Colored Progressive Matrices to a subpopulation of a Sardinian sample of 1626 children attending the primary and secondary level of education of the Italian scholastic organization. The main objective of the research concerns the construct validity and the psychometric properties of the global test instrument.
