Developmental language disorder (DLD) is a common disorder in childhood. The aim of this study was to investigate the performance of Persian-speaking children with and without DLD in sentence repetition as a clinical marker.
As a cross-sectional and observational study, seven 5-to-7-year-old Persian-speaking children with DLD and thirty normal peers were studied using the Persian version of test of language development (TOLD-P: 3) as a diagnostic test and sentence repetition task (SRT). Finally, the performance of two groups on the SRT was compared by statistical tests at the significance level of 0.05.
The score of sentence repetition task between the children suspected to have DLD and their normal peers were significantly different (P<0.05). Indeed, there was a significant difference between the groups in terms of the mean scores of prepositions (P<0.01), conjunctions (P<0.01), plural case (P<0.01), subject-verb agreement (P<0.05), and word order (P<0.05).
The sentence repetition can be used as a clinical marker for early detection and intervention of Persian-speaking children with DLD.
