Background: This study aimed to investigate some child- and environmentdependent
factors in a retrospective method to find a prediction model for the
spoken language development of children with hearing loss (HL) after cochlear
implantation (CI).
Methods: The research reported here was conducted as a cross-sectional 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 via consecutive sampling methods
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 Sentence Repetition
Test (SRT). The correlation between the independent variables and SRT scores of
the groups were compared in two stages.
Results: Regarding the development of spoken language in two groups of
Persian-speaking preschool children using the 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.
Conclusion: According to this study’s findings, the child’s IQ, the duration of
watching TV during the day, the duration of playing with the father during the
day, the level of education of the mother, the level of education of the father, and
the economic level of the family may be considered the predictive factors in the
language development of cochlear implant children during the preschool years.
