Why the change?

The language we use can affect the services that Children receive Can’t do research without common definitions

Questions we need to answer

  • Which children should get extra help?
  • Audit: how many SALTs do we need?
  • Is rate of language problems

increasing/decreasing over time?

  • How do different countries/region compare?
  • What causes children’s language problems?

SLCN

e.g. genetic conditions such as cerebral palsy

e.g. ASC

e.g. language difficulties acquired after brain injury

DLD 7.6%

e.g. speech sound disorders

  • verbal learning / memory
  • syntax
  • semantics
  • word retrieval
  • pragmatics
  • phonology

Biomedical conditions

  • Language disorder associated with known genetic

condition (e.g. Down syndrome, Klinefelter syndrome)

  • Acquired brain injury
  • Sensorineural hearing loss
  • *Intellectual disability
  • *Autism spectrum disorder

*Included because growing evidence of genetic basis for these

conditions 58

What is new?

  • Developmental language disorder (DLD) to replace SLI
  • Disorder defined in terms of functional impairment

and poor prognosis

  • Rather than exclusionary factors, ‘Language disorder

associated with X’ – also need assessment/intervention

  • Does not use invalid delay/disorder distinction
  • Does not use social background as criterion
  • Does not use nonverbal IQ as criterion
  • Additional disorders as descriptor rather than

exclusionary factor 51
