Macarthur Communicative Development Inventories (User's Guide And Technical Manual)2023

Essential for use alongside the MacArthur-Bates Communicative Development Inventories (CDIs), Third Edition, the User’s Guide and Technical Manual provides information on the development of third edition of the inventories, provides guidance on which inventories to use with which populations, and describes how to deliver, score, and interpret the tools.ABOUT THE CDIs Used in both research and clinical settings, these parent report instruments help SLPs and other professionals screen children, develop a prognosis for children with language delays, plan effective intervention, monitor progress, and meet mandates for including parent input in child evaluation. The CDIs include measures for three age ranges: • Words and Gestures form (ages 8 to 18 months). With this comprehensive instrument, parents document the child’s understanding of hundreds of early vocabulary items, and the form yields separate indexes of words understood and words produced. Then, parents record communicative and symbolic gestures the child has tried or completed • Words and Sentences form (ages 16 to 30 months). Parents use this comprehensive instrument to document the child’s production of hundreds of words, record the child’s use of early forms of grammar, and provide written examples of the child’s three longest utterances. • CDI-III (ages 30 to 37 months). This shorter, single-sheet tool measures expressive vocabulary and grammar. See the Third Edition Set to learn more.
