Preschoolers with language disorders: 10 years later.

Language, intelligence, academic achievement, and behavioral adjustment were assessed in a group of 20 adolescents originally studied 10 years earlier as preschoolers with language disorders. At follow-up, 20% had WISC-R IQ scores in the mentally deficient range and were being educated in EMR classrooms. Of the remaining 16, 11 (69%) had required special tutoring, grade retention, or LD class placement. The majority of non-EMR subjects continued to evidence persistent deficits in language and academic achievement and were rated by their parents as being less socially competent and having more behavioral problems than their peers. Of the initial preschool measures available, the Leiter was found to be the best single predictor of intelligence, language, class placement, and reading achievement in adolescence, although the NSST: Expressive subtest also was a strong predictor of adolescent language.
