['The purpose of this study was to make a quantitative comparison of parameters of self-esteem and social well-being between children with cochlear implants and normal-hearing children.', 'Data were obtained from 164 children with cochlear implant (CI) and 2169 normal-hearing children (NH). Parental questionnaires, used in a national survey assessing the self-esteem and well-being of normal-hearing children, were applied to the cochlear implanted group, in order to allow direct comparisons.', 'The children in the CI group rated significantly higher on questions about well-being in kindergarten/school and the CI boys appeared to manage school work better than normal-hearing boys. CI children were significantly more active and bullied other children less than normal-hearing peers, whereas no difference existed as to being bullied by other children. No difference was obtained regarding overall self-esteem or number of friends. The two groups of children scored similarly on being confident, independent, social, not worried and happy.'] Do self-esteem and social well-being of children with cochlear implant compared to normal-hearing children?
