Comment:
The original version of the inventories was developed in 1975 by Bates, Camaioni, & Volterra, but the inventories have much changed since then
The MB-CDI is divided in to two parts. The CDI/Words and Gestures (CDI-WG) is designed for children 8 to 16 months old (also referred to as CDI Infant form, and the CDI/Words and Sentences (CDI-WS) is designed for children 16 to 30 months old (also referred to as the CDI toddler form)
Short versions of the MB-CDI also exist as well as the MB-CDI III which includes an extension for three year olds
Year: 1993
