The influence of cochlear implants on behaviour problems in deaf children

Abstract

Background: This study seeks to analyse the relationship between behaviour problems in deaf children and their auditory and communication development subsequent to cochlear implantation and to examine the incidence of these problems in comparison to their hearing peers.

Method: This study uses an ex post facto prospective design with a sample of 208 Spanish children, of whom 104 were deaf subjects with cochlear implants. The first objective assesses the relationships between behaviour problems, auditory integration, and social and communication skills in the group of deaf children. The second compares the frequency and intensity of behaviour problems of the group of deaf children with their hearing peers.

Results: The correlation analysis showed a significant association between the internal index of behaviour problems and auditory integration and communication skills, such that deaf children with greater auditory and communication development had no behaviour problems. When comparing behaviour problems in deaf children versus their hearing peers, behavioural disturbances are significantly more frequent in the former.

Conclusions: According to these findings, cochlear implants may not guarantee adequate auditory and communicative development that would normalise the behaviour of deaf children.
