Clinical characteristics of children referred to a child development center for evaluation of speech, language, and communication disorders.

Speech, language, and communication disorders are prominent reasons for referrals to a child development center. From 1984 to 1988, 1,090 preschool children were referred to our child development center, which serves the Tel Aviv metropolitan area. Of all referrals, 432 (41%) were primarily due to speech, language, and communication problems. After exclusion of those with IQ < 50 and those with non-language-related disabilities, 323 children remained. The children were classified into different subtypes of developmental language disorders and autistic spectrum disorders. The main developmental language disorder subtypes were combined expressive-receptive (49%) and expressive (44%). Central processing deficits were less common, occurring in 20 (7%) of the children. Parents of children with developmental language disorders had educational levels similar to those of parents of children referred to the child development center for other causes. However, parents of children with infantile autism had higher educational levels than parents of children with developmental language disorder or parents of children referred for other causes (P < .001). Our results reflect the distribution of language and related problems in an unselected population of preschool children referred to a child development center.
