Abstract
The MacArthur–Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994 ), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N=113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and receptive language and measures from parent–child conversation. Associations indicated reasonable concurrent and predictive validity. The findings suggest that satisfactory vocabulary scores at age 2 are likely to predict normal language skills at age 3, although some children with limited skills at age 3 will have had satisfactory scores at age 2. Many children with poor vocabulary scores at 2 will have normal skills at 3.Keywords
