Rehabilitation of Narrative Language in Children With Hearing Impairment and Developmental Language Disorder

Assessment and Rehabilitation of Narrative Language in Children With Hearing Impairment and Developmental Language Disorder

The importance of narrative skills is evident in their role in language development and their relation to important academic skills namely reading, comprehension, and writing. Narratives are also essential for competent social skills, and children with delayed language development are usually found to have less proficient social communication skills. Research demonstrates the effects of narrative language intervention on improved narrative structure and complexity in addition to improved receptive and expressive use of syntax, morphology and general language use in children with narrative language impairment in various types of communication disorders. Given the importance of narrative language abilities in language development and due to lack of research targeting the assessment and intervention of narrative language skills of Arabic speaking children with language impairments, this study is dedicated towards the assessment of narrative language in Arabic speaking children and the development of a comprehensive intervention program targeting narrative language skills and its application on children with hearing impairment and developmental language disorder.

Study Overview

• Status: Completed
• Conditions: Developmental Language Disorder; Hearing Impaired Children
• Intervention / Treatment: Behavioral: Narrative language intervention program; Behavioral: Conventional language intervention

Detailed Description

A narrative refers to the ability to produce a fictional or real account of temporally sequenced meaningful occurrences and experiences. Studies have shown that narrative competence increases with age alongside language, cognitive and social skills. Development of narrative abilities starts during the preschool years, expands during the school age years, and continues to develop through adolescence and even adulthood.

Children with developmental language disorder (DLD) are known to have impaired narrative skills. Narratives of children with DLD are characterized by incomplete episodes, poor coherence, less expression of cognitive states, less complex sentences with fewer dependent clauses, and less complex morpho-syntax when compared to their peers.

Research has also shown that hearing impairment is another communication disorder in which narrative skills are particularly vulnerable. Narratives of children with hearing loss demonstrate comprehension and production deficits and they have a statistically significant lower performance in tests assessing narrative structure.

The aim of this work is to develop a narrative language intervention program and to apply it on children with developmental language disorder and children with hearing impairment to detect its efficacy on improving their narrative and language skills.

This study will be conducted on 44 children with hearing impairment, and 44 children with developmental language disorder attending the Unit of Phoniatrics, in the outpatient clinic of Alexandria Main University hospital. Sample size was calculated to achieve 80% power with a target significance level at 5% to detect the efficacy of the proposed narrative intervention program in improvement of narrative language skills of Egyptian children with hearing impairment and developmental language disorder.

The narrative intervention program will include an introductory section on the elements of story grammar to introduce the children to narratives and give them explicit instructions about the concepts of narrative macrostructure. The program will include 24 illustrated story sequences with a minimum of 5 sequences representing the main story elements: characters and setting; problems; internal response; actions; and consequence. Story icons will be designed to represent the main 5 elements to accompany storytelling and act as visual prompts. Each story will reflect specific content with several target vocabulary words and complex morphosyntax.

The following procedure will be implemented with each story: Modeling, answering comprehension questions, retelling with icons and colored illustrations, retelling with icons only, and retelling without icons.

All subjects meeting the specified inclusion and exclusion criteria will be assessed by the specified protocol of assessment to evaluate narrative skills, language skills and cognitive abilities before and after intervention.

The results of this study will be tabulated and analyzed with the use of appropriate statistical methods and appropriate figures and diagrams.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Hearing Impairment cases; Hearing impaired children who will receive the proposed narrative intervention program. The program will include 24 illustrated story sequences with a minimum of 5 sequences representing the main story elements: characters and setting; problems; internal response; actions; and consequence. Story icons will be designed to represent the main 5 elements to accompany storytelling and act as visual prompts.The narrative intervention program will be applied on the cases groups by a phoniatrician in 24 sessions, 60 minutes in duration, one session per week, for 3 months.	Behavioral: Narrative language intervention program; Narrative language targets improving narrative macrostructure and microstructure. The program will include 24 illustrated story sequences with a minimum of 5 sequences representing the main story elements: characters and setting; problems; internal response; actions; and consequence. Story icons will be designed to represent the main 5 elements to accompany storytelling and act as visual prompts. Each story will reflect specific content with several target vocabulary words and complex morphosyntax. Each story will be followed by comprehension questions to facilitate understanding and answering question about stories. The following procedure will be implemented with each story: Modeling, answering comprehension questions, retelling with icons and colored illustrations, retelling with icons only, and retelling without icons. This procedure is adapted from story champs intervention program
Active Comparator: Hearing Impairment control; The Hearing impairment control group will receive the conventional language rehabilitation sessions in 30 minute sessions twice a week, for 3 months. Conventional language therapy targets semantics, syntax, prosody, pragmatics, and phonology.	Behavioral: Conventional language intervention; Language rehabilitation targets improving semantics, syntax, pragmatics and phonology.
Experimental: Developmental language disorder cases; Developmental language disorder children who will receive the proposed narrative intervention program. The program will include 24 illustrated story sequences with a minimum of 5 sequences representing the main story elements: characters and setting; problems; internal response; actions; and consequence.
