title: [Determination of the concurrent validity of the CRAFT-d - a screening instrument for problematic alcohol consumption].
abstract: OBJECTIVE
  The aim of this study was to determine the concurrent validity of the CRAFFT-d alcohol abuse screening test for adolescents.
  
  
  METHODS
  This criterion-related validity study compared the decisions of the CRAFFT-d with the decisions of the concurrently administered Alcohol Use Disorders Identification Test (AUDIT). Data was obtained from an online questionnaire including CRAFFT-d and AUDIT.
  
  
  RESULTS
  Of the 12250 participants, 54.2 % were found to have an alcohol use disorder due to the AUDIT. CRAFFT-d identifies 63.6 % with problematic alcohol consumption. The Phi-coefficient showed high agreement between AUDIT and CRAFFT-d classifications (Phi Phi = .57; chi(2) 3978.671**; df = 1, p > .001). At a score of 2 or higher, CRAFFT showed sensitivity of 88.8 % and specificity of 66.2 %.
  
  
  CONCLUSIONS
  The CRAFFT-d is a valid instrument for screening adolescents for problematic alcohol consumption. However, further comparison of CRAFFT items with diagnostic criteria for adolescents is needed.
