Normativization to the Spanish-Colombia to the CDI- MacArthur-Bates Communicative Development Inventories

The MacArthur-Bates Communicative Development Inventories-CDT (Fenson et al., 2007) is an instrument that allows a valid and reliable assessment of the communicative and linguistic development in young children. This paper describes the normalization process of the instrument to the language and cultural context of Colombia, as well as the first part of creation of the age-expected scores for the Capital city (Bogota). The parents of 825 children, between 8 and 30 months from different socioeconomic backgrounds residing in Bogota's greater area, completed the adapted inventories. Statistical analysis included reliability and validity measures, which suggest internal consistency and a good predictive value for the scales version. Results allow the identification of developmental rhythms in language acquisition for colombian children, where discontinuities and reorganizations are the common note with different CDI adaptations around the world.
