Relationships between chronological and linguistic age and phonological awareness in children with developmental language disorder

Abstract

ABSTRACT Purpose: to verify whether there is a relation between linguistic age and performance in phonological awareness of children presented with developmental language disorder. Methods: a retrospective study comprising 53 children with developmental language disorder aged between 4 and 7 years old. Their language disorder diagnosis followed the inclusion criteria internationally described and Brazilian standardized tests for language assessment were used. All children underwent phonological awareness and linguistic skills assessment via standardized tests and all data went through statistical analysis. For correlation analysis, the p-value was performed through the Pearson’s test. In the regression analysis the models used expressive and receptive linguistic age as independent variables and the performance in phonological awareness as a dependent variable (p=0,036* and p= 0,048*). Results: the data indicated a strong correlation between language age and phonological awareness skills in children with language developmental disorder. A strong correlation between syllabic awareness and linguistic age was found as well. In addition, phonemic awareness was correlated to their chronological age. All correlation tests were confirmed by regression analysis. Conclusion: the data indicated a strong correlation between linguistic age and phonological awareness in children with developmental language disorders. These findings raise discussion regarding phonemic skills in children under this condition and their literacy process.
