Inventario I: Primeras Palabras y Gestos, sold in packages of 25 for easy re-ordering, is one of the two standardized, parent-completed report forms that make up the the Spanish adaptation of the MacArthur Communicative Development Inventories (CDIs), which was designed by top language researchers to assess language and communication skills in young children ages 8-30 months. With the Inventarios, professionals can tap into parents' invaluable day-to-day knowledge about their children's language and communication skills--and respond to legislation that requires parental input in child evaluations. The forms focus on current behaviors and salient emergent behaviors that parents can recognize and track. Numerous studies document the reliability and validity, clinical utility, and research potential of the CDIs and Inventarios. The CDIs were normed on approximately 1,800 children in three locations, and the Inventarios were normed on more than 2,000 children. The CDI and Inventario forms were developed separately to reflect the vocabulary and grammatical structure of each language. Inventario I: Primeras Palabras y Gestos is a "words and gestures" form for use with children ages 8-18 months. The first part of the form prompts parents to document the child's understanding of hundreds of early vocabulary items separated into semantic categories such as animal names, sound effects, and question words. Parents mark the words understood or used, and the form yields separate indexes of words understood and words produced. The second part of the form asks parents to record the communicative and symbolic gestures the child has tried or completed. This form generally takes 20-40 minutes to complete and 20-30 minutes to score by hand. Also available are the Inventario II: Palabras y Enunciados and the User's Guide and Technical Manual. These forms are part of the MacArthur-Bates Inventarios del Desarrollo de Habilidades Comunicativas (Inventarios). The Inventarios and their English version, the CDIs, are standardized, parent-completed report forms that track young children's language and communication skills. Top language researchers developed the report forms, designing them to focus on current behaviors and salient emergent behaviors that parents can recognize and track. This product is sold in a package of 25. Learn more about the MacArthur-Bates CDIs.
