title: Concurrent validity of caregiver/parent report measures of language for children who are learning both English and Spanish.
abstract: The validity of two analogous caregiver/parent report measures of early language development in young children who are learning both English and Spanish is examined. Caregiver/parent report indices of vocabulary production and grammar were obtained for 26 children using the MacArthur Communicative Development Inventory: Words & Sentences (CDI; Fenson et al., 1994) and the Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC; Jackson-Maldonado, Bates, & Thal, 1992). Scores were significantly correlated with analogous laboratory measures in both English and Spanish, including a real-object naming task and spontaneous language use during free-play. The findings offer evidence that the CDI and IDHC provide valid assessments of early language milestones in young English- and Spanish-speaking children. Factors that may influence the validity of these tools for use with this population are also discussed.
