Abstract

This study considers the validity of the Words and Gestures and Words and Sentences portions of the MacArthur Communicative Development Inventories (MCDI) for pediatric cochlear implant users who exceed the age ranges for which these inventories were normed. In Experiment 1, scores on the Words and Gestures measures were compared with scores on behavioral receptive and expressive vocabulary and language measures at preimplantation and again at 6 months postimplantation. Children ranged in age from 17 to 72 months, and results revealed significant correlations (r-values: .38-.80), with the strongest correlations resulting between MCDI measures and raw scores derived using the Reynell Developmental Language Scales (RDLS). Correlations also obtained between the number of words produced reported on the MCDI Words and Gestures inventory and the Peabody Picture Vocabulary Test-Third Edition (PPVT-III). Experiment 2 compared scores on the Words and Sentences measures with the same behavioral receptive and expressive vocabulary and language measures at 12 and 18 months postimplantation. Children ranged in age from 38 months to 67 months, and significant correlations obtained between behavioral measures and Words and Sentences measures assessing word production as well as grammatical ability (r-values: .60-.90). The strong validity findings motivated Experiment 3, in which predictive formulas were developed to predict scores on the RDLS based on scores from the MCDI. These models will allow researchers and clinicians to use a single index to assess the language abilities of a broad range of ages and performance abilities within the pediatric cochlear implant population.
