Process of Effect of Language Development on Behavior Problems in Children with Cochlear Implanted: the Mediating role of Private Speech and Self-Regulation

The main purpose of this study is to predict behavior problems by language development and secure attachment based on mediation role of self-regulation in cochlear implanted children. In this correlation study 114 available cochlear implanted children in the age range of 3-7 years that at least one year has passed from the Cochlear Implant program were selected with available sampling method. Test of language development (Newcomer and Hammill, 1997), and Structured Observation of Behavioral Regulation (Ponitz and et al, 2008) were administered on children, and their mothers responded to Private speech scale (Amraei, 2016) and Preschool Children Behavioral Disorder (Shahim and Yousefi, 1999). Path analysis was employed in order to analyze the data. The results of the study showed that language development (b= 0/60, P<0/01) predicting %36 of variance of private speech. Also, language development (b= 0/45, P<0/01) and private speech (b= 0/28, P<0/01) have the ability to predict %52 of self-regulation. Finally, language development (b= -0/23, P<0/01) with the mediating role of private speech (b=- 0/33, P<0/01) and self-regulation (b= -0/29, P<0/01) have the ability to predict %53 variance of behavior problem. The research showed behavior problems can be predicted by Language development, with the mediating role of private speech and self-regulation, in cochlear implanted children. This result can apply in prediction and rehabilitation programs for reducing behavior problems.
