MacArthur-Bates Communicative Development Inventories (CDI), Third Edition Set (Paperback)

The MacArthur-Bates Communicative Development Inventories (CDIs) are one of the most widely used and recommended measures of language and communication for young children.

ThisCDI Third Edition Print Set includes:

• Paperback User’s Guide
• 25 paper Words & Gestures forms
• 25 paper Words and Sentences forms
• 25 paper CDI-III forms

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.

WHAT’S NEW

The third edition of the CDIs includes updated norms, additional tools, and more administration formats and helpful resources. Here’s a look at what’s new:

• Expanded and more representative norms—more than 4,000 new children have been added to the norming dataset for the CDI: Words and Gestures and CDI: Words and Sentences. Norming tables have been statistically adjusted to reflect key U.S. demographic indicators.
• More options for electronic administration of the CDIs, including fillable PDFs and a new web-based administration platform, Web-CDI
• New picture-based instructions with easy-to-understand illustrations and examples
• More extensive administration and scoring guidelines
• More on using the CDIs with bilingual and multilingual children
• An expanded chapter on the CDI-III
• Detailed guidelines about choosing the most appropriate CDI forms when several are potentially useful
• Expanded guidelines on the use of CDI short forms, including new statistically-adjusted norms and information on reliability and validity
• More CDI resources available online, including Wordbank, an open repository of CDI data in 38 languages representing more than 84,000 children
• A rapid, valid Computerized Adaptive scale for expressive vocabulary, now available through Web-CDI
• A helpful list of

Larry Fenson, Ph.D., is Professor of Psychology at San Diego State University in California. Dr. Fenson has published research on infant attentiveness, early symbolic development, categorization, children's drawing skills, play, and early language development. He received his doctorate in child psychology from the University of Iowa. He served as Assistant Professor at the University of Denver and was a National Institute of Child Health and Human Development postdoctoral fellow with Jerome Kagan at Harvard University.

Donna J. Thal, Ph.D., holds a master of science degree in speech pathology and audiology from Brooklyn College and a doctorate in speech and hearing sciences from the Graduate School and University Center of the City University of New York (CUNY). She has been a postdoctoral fellow at the Center for Research in Language at UCSD, an assistant professor at Hofstra University, and an assistant professor at Queens College of CUNY. Dr. Thal is a developmental psycholinguist and a certified and licensed speech-language pathologist who has conducted research in a number of areas, including normal and disordered development of language and cognition, children with focal brain injury, and children with delayed onset of language. She has also carried out studies of language development in Spanish-speaking infants and toddlers. Her most recent work focuses on early identification of risk for clinically significant language impairment and is funded by a grant from the National Institute of Deafness and Other Communicative Disorders (NIDCD), within the National Institutes of Health. Dr. Thal is an editorial consultant for language for the Journal of Speech, Language, and Hearing Research and the American Journal of Speech-Language Pathology.

Philip S. Dale, Ph.D., is Professor in Departments of Psychology, Linguistics, and Speech and Hearing Sciences at University of Washington. Dr. Dale's research interests include assessment of young children's language, language development in exceptional populations including linguistically precocious children, early language and cognition, and the effects of various models of intervention for young children with disabilities.

J. Steven Reznick, Ph.D., is an affiliate of the Department of Psychology at the University of North Carolina at Chapel Hill.

Dr. Bates was a founding member of the Cognitive Science Department at University of California at San Diego (the first of its kind in the world), the Director of the federally-funded UCSD Project in Cognitive and Neural Development, a founding co-director of the innovative Joint Doctoral Program in Language and Communicative Disorders at San Diego State University and UCSD, and the Director of the Center for Research in Language and Professor of Cognitive Science at UCSD. With strengths in developmental psychology, linguistics, neurology, and cognitive science, she carried out many creative and influential collaborative studies on the interrelations among language acquisition, brain function, symbolic growth, and other key aspects of development. During her extensive career, she directed cross-linguistic studies on 4 continents and authored or co-authored 10 books and more than 200 scientific publications. Her work was interdisciplinary, influencing diverse fields such as neuroscience, linguistics, biology, psychology, computer science, and medicine.
