Auditory skills, language development, and adaptive behavior of children with cochlear implants and additional disabilities.

Objective: The objective of this study was to evaluate the development of functional auditory skills, language, and adaptive behavior in deaf children with cochlear implants (CI) who also have additional disabilities (AD).

Design: A two-group, pre-test versus post-test design was used.

Study Sample: Comparisons were made between 23 children with CIs and ADs, and an age-matched comparison group of 23 children with CIs without ADs (No-AD). Assessments were obtained pre-CI and within 12 months post-CI.

Results: All but two deaf children with ADs improved in auditory skills using the IT-MAIS. Most deaf children in the AD group made progress in receptive but not expressive language using the preschool language scale, but their language quotients were lower than the No-AD group. Five of eight children with ADs made progress in daily living skills and socialization skills; two made progress in motor skills. Children with ADs who did not make progress in language, did show progress in adaptive behavior.

Conclusions: Children with deafness and ADs made progress in functional auditory skills, receptive language, and adaptive behavior. Expanded assessment that includes adaptive functioning and multi-center collaboration is recommended to best determine benefits of implantation in areas of expected growth in this clinical population.
