FARKAS, CHAMARRITA. McArthur'Bates Communicative Development Inventory (CDI): Proposal of an Abbreviate Version. Univ. Psychol. [online]. 2011, vol.10, n.1, pp.245-262. ISSN 1657-9267.

The McArthur-Bates Communicative Development Inventories (CDI) assesses language development en children, through a significant caregiver report. The first inventory assesses verbal and non verbal language in infants who are from 8 to 18 months old and it is composed of 949 items distributed in 6 scales. This study proposes an abbreviate form of this instrument, and was tested on families and educators of 130 Chilean children of 11-15 months old. Analyses related to the items, reliability and validity of the instrument and factorial analyses of subscales were realized. The abbreviate version consider 241 items distributed in 4 scales. The evaluation of the psychometric properties of the instrument was acceptable, demonstrating adequate reliability and validity.
