title: Usefulness of the Bayley scales of infant and toddler development,third edition, in the early diagnosis of language disorder.
abstract: BACKGROUND
  Language disorder (LD) is a neurodevelopmental disorder, and early diagnosis has an impact on speech therapy practice. The aim of this work is to test the usefulness of the Cognitive and Language scales of the Bayley-III in the early diagnosis of LD.
  
  
  METHODS
  In a longitudinal study, a clinical sample of 187 children with diagnostic hypothesis of communication disorders at 4.5 years was assessed with the Bayley-III before age 3.5 years and subsequently with other scales of different psychological and psycholinguistic functions.
  
  
  RESULTS
  The results indicate that children with LD scored significantly lower than their control groups in all subtests and compounds of the Bayley-III. Additionally, low scores on the Language composite in the Bayley-III predicted lower scores in the Auditory-vocal Channel of the ITPA. A significant correlation was obtained between the Cognitive Scale of the Bayley-III and the General Cognitive Scale of the MSCA and the Mental Processing Composite of the K-ABC.
  
  
  CONCLUSIONS
  We can draw the conclusion that the Cognitive and Language scales of the Bayley-III are a useful instrument for early diagnosis of LD, and can also discriminate more severe forms of LD.
