The investigation of efficacy of narrative-based language intervention (NBLI) on narrative production structures in Persian-speaking cochlear implanted children
Objectives: The aim of this study is determination of efficacy of narrative-based language intervention (NBLI) on story-telling skills in cochlear implanted children.
Design: The study will design in order to Randomized Clinical Trial.
Major Inclusion criteria: Persian-speaking cochlear implanted children who have 5 to 7 years old, enable to produce sentences, and having psycho-physical health.
Major Exclusion criteria: Demolishing the cochlear prosthesis during intervention in any type for more than 2 weeks, and no tendency to continue of study by child or his/her family. Sample size of study is 36 children.

Duration of intervention will be long 2 months and a two-monthly period will be considered for follow-up. The control group of study will be received conventional speech therapy similar to intervention group.
Main outcomes measures: Frequency of story grammars, production of main information of story, observing the event sequencing, percent of narrative cohesion, and percent of accuracy performance in story-telling
