The Chinese Communicative Development Inventories are checklists for parents or other caregivers of Putonghua- (Mandarin) or Cantonese-learning children. They are published by Peking University Medical Press and distributed by the Center for Human Growth and Development, University of Michigan.  These instruments were normed for native Mandarin- or Cantonese-speaking families with typically developing children, aged 8 to 30 months, in Beijing and Hong Kong. 

They can be used with native or non-native speakers of Putonghua (Mandarin) or Cantonese, and atypically developing children from Putonghua- or Cantonese-speaking households. However, caution is advised in using the norms with populations that differ from the norming samples.

Development of these inventories was approved by the CDI advisory board and based on the widely used MacArthur-Bates Communicative Development Inventories in English and include both "Words and Gestures" and "Words and Sentences" Long and Short Forms (a total of 8 forms) that can be copied for individual use.  In addition to the forms, a User's Manual, description of the procedures used to develop the forms, the norming study results, and percentile ranks (by age and gender) for each of the forms are included.  For further information or information on ordering a copy of the User's Guide and Manual, please see below.
