title: [Diagnostic accuracy of language tests and parent rating for identifying language disorders].
abstract: BACKGROUND
  Until now German language tests have been rarely evaluated for their diagnostic accuracy. The goal of the study was to determine whether frequently used German language instruments are valid measures for identifying developmental language disorders in 3-year-old children.
  
  
  METHODS
  The language test SETK 3-5 (including the short version SSV) and the parent questionnaire SBE-3-KT were administered to 88 children with and without language impairment. The procedure of the selection of children enabled an extrapolation to general population. A language sample rating was used as a gold standard.
  
  
  RESULTS
  Depending on case definition 6-22% of children were classified as language impaired by SETK 3-5, 9% by SSV and 15% by SBE-3-KT. Sensitivity, specificity and positive predictive values of SETK 3-5 for specified cut-offs were 35-93%, 86-97% and 41-58%, respectively. The corresponding values of SSV were 49%, 96%, 56% and of SBE-3-KT 92%, 93%, 59%.
  
  
  CONCLUSIONS
  3-year-old children with developmental language disorders can been identified with sufficient accuracy by means of SETK 3-5, an individual language test, as well as by SBE-3-KT, a parent questionnaire. However, the number of false positive classifications is relatively high. The hit rate of SSV, an individual short test, was too low for clinical use.
