Abstract

The structure of phonological processing for typically developing children has been debated over the past two decades. Recent research has indicated that phonological processing is best explained by a single underlying phonological ability (e.g., Anthony and Lonigan, 2004). The current study had two goals. The first goal was to determine the structure of phonological processing for school-age children with mild intellectual disabilities (MID). The second goal was to determine the relationship between the components of phonological processing and expressive and receptive language ability. The participants were 222 school-age children identified by their schools as having MID. Confirmatory factor analysis was utilized to determine the structure of phonological processing. The results indicated that a model with one phonological awareness factor and one naming speed factor explained the data better than competing models with a single latent factor or more than two latent factors. There was a negative significant relationship between phonological processing and naming speed. There were positive bivariate relationships between phonological processing and expressive and receptive language. There were negative bivariate relationships between naming speed and expressive and receptive language. These results are consistent with other research findings with typically developing children, indicating a similarity in the relationships between phonological process and language for children with MID. Theoretical and instructional implications are discussed.
