The MacArthur-Bates CDI-III for Spanish-speaking Children
Parent report measures have been shown to be effective, valid and cost-effective means for obtaining information about early child language development. There are several measures available in multiple languages for children below the age of 3. There has been a need for such measures for older children. This study presents the development of a Spanish version of the MacArthur-Bates Communicative Development Inventory-III for children 2 ½ to 4 years of age. A total of 571 families of monolingual Spanish-speaking children from a diverse socio-economic group were asked to fill out the parent report measure in order to obtain a norming sample. Data are presented by age and socio-economic groups that show developmental growth curves for vocabulary production and sentence complexity. Norming tables that show variability by ages are presented. Additional information is given for a General Concepts section. This study presents a new parent report instrument that can be used both clinically and for research purposes.
