Children screening positive for language delay at 2.5 years: language disorder and developmental profiles

To characterize language disorder and developmental profiles in children who screened positive for language delay but negative for autism at 2.5 years of age.

The first 100 children who screened positive for language delay - but negative for autism - in 2016 were assessed in detail by speech language pathologists. Parents completed a newly developed questionnaire covering eight domains - Motor, Executive functions, Perception, Memory, Language, Learning, Social skills and Child's behaviour - with impairment scored for each domain.

ICD-10 language disorder diagnoses were made in 87/100 children (29 girls, 58 boys). Of 52 children with mixed receptive-expressive language disorder, 32% had problems in other developmental areas according to the "global rating" in the impairment questions of the questionnaire. Of the 35 with expressive language disorder, 21% had problems in other areas according to the impairment questions. Thirteen children had isolated language delay with no other diagnoses according to the speech and language pathologists' assessment; however, 23% of them had problems according to the parental rating on the impairment questions.

Most children screening positive for language delay but negative for autism at age 2.5 years were diagnosed with ICD-10 language disorder diagnoses. Parents in about one in four cases reported impairing problems within other developmental areas. Possible explanations for the findings are discussed.
