title: [Diagnostic value of ERTL4: a screening test of language disorders in 4-year-old children].
abstract: BACKGROUND
  Language disorders in children are frequent and may sometimes severely affect their development. ERTL4 (screening test for language disorders of children aged 4) is the first test for screening language disorders to be used by doctors. It has not yet been evaluated.
  
  
  OBJECTIVE
  The objective of this study is to assess and optimize the diagnostic value of the ERTL4 test and to evaluate its potential interest as a screening test.
  
  
  METHODS
  A sample of 370 children was randomly constituted among children aged between 3 years 9 months and 4 years 6 months from schools in Nancy, France and surrounding areas. These children undertook both the ERTL4 test and a standardized examination of language and speech as a reference.
  
  
  RESULTS
  Among the 325 children included in the analysis, 34.1% presented with disorders requiring speech and language therapy. ERTL4 sensitivity and specificity were 88.6% and 66.8%, respectively. Varying thresholds for disorder diagnoses and proposals for a modified test led to a sensitivity of 72.9% and a specificity of 91.0%. The proportion of well-classified subjects improved from 73.8% to 85.3% (P < 10(-3)). The positive predictive value was 78.7% and the negative predictive value was 88.1% (with the observed frequency in the sample).
  
  
  CONCLUSIONS
  ERTL4 is a good test for doctors to screening of children's language disorders and their management.
