ABSTRACT

Background & Objectives
For children speaking various languages including English, Chinese and French, sentence repetition has been found to be one of the best clinical markers of specific language impairment. In the present study, the accuracy of a sentence repetition test in diagnosing specific language impairment among Korean preschool children was investigated.
Methods
Sixteen five- to six-year-old children with specific language impairment, 16 typically developing children with matched chronological ages, and 16 younger children with matched language ages participated in the present study. A sentence repetition test containing 36 sentences of varying length and syntactic complexity was developed. The children’s performances on the sentence repetition test were scored in two different ways. The sentence level scoring system followed the ‘correct - incorrect’ criteria used in most standardized tests where a single error made during sentence repetition lead to a 0 score. In the word-level scoring system, correctly repeated words were counted.
Results
The children with specific language impairment performed significantly more poorly compared to their typically developing peers, but no significant difference was observed compared to the younger children with matching language skills. The children’s performances on the sentence repetition test correlated significantly with performances on other language tests but in different ways across the groups. The sensitivity, specificity, and positive/negative predictive values of the sentence repetition test in diagnosing specific language impairment were greater than 85% in both the five- and six-year age groups. The positive likelihood ratios for these age groups were 20.83 and 11.0, and the negative likelihood ratios were 0.13 and 0.09, respectively.
Discussion & Conclusion
The sentence repetition test was found to be very accurate in diagnosing specific language impairment among Korean preschool children aged five to six years.
