A short version of the MacArthur-Bates Communicative Development Inventories with high validity.The MacArthur-Bates Communicative Development Inventories (CDIs) are among the most widely used evaluation tools for early language development.  CDIs are filled in by the parents or caregivers of young children by indicating which of a prespecified list of words and/or sentences their child understands and/or produces.  We present a new method through which an estimation of the full-CDI score can be obtained, by combining parental responses on a limited set of words sampled randomly from the full CDI with vocabulary information extracted from the WordBank database, sampled from age-, gender-, and language-matched participants.
