The aim of this study was to investigate some child- and environment-dependent factors in a retrospective method in order to find a prediction model for the spoken language development of children with hearing loss (HL) after cochlear implantation (CI).
The research reported here was conducted as a pilot study. The sample size was 18 Persian 5-to-7-year-old children with HL using CI (6 girls and 12 boys) who were recruited through consecutive sampling method from Soroush Rehabilitation Center in Shiraz, Iran. The studied independent variables were categorized into child-related variables and parental variables. At the first step, the participants were divided into two groups, good language ability and poor language ability, based on the results of the Sentence Repetition Test (SRT). The correlation between the independent variables and SRT scores of the groups were compared in two stages.
Regarding the development of spoken language in two groups of Persian-speaking preschool children using cochlear implants with good and poor language development, IQ, duration of watching TV, duration of playing with the father, education status of the mother, education status of father, and economic status of the family had a significant correlation with language development of these children.
In general, the higher the child's intelligence and the parents' socioeconomic status, the better his interaction with parents and others around him/her. Therefore, these factors may be considered as predictive factors in language development of cochlear implant children during the preschool years.
