title: [Validation for Colombia of the CRAFFT substance abuse screening test in adolescents].
abstract: OBJECTIVE
  Evaluate the properties of CRAFFT scale for substance abuse screening in adolescent population aged 14 to 18.
  
  
  METHODS
  The criteria was validated by comparing the CRAFFT scale to the gold standard for substance use identification (i.e. the clinical interview). The diagnostic test model was used for calculating the sensitivity, specificity and predictive values of the scale.
  
  
  RESULTS
  The test revealed 0.95 sensitivity, 0.83 specificity, 0.85 PPV and 0.94 NPV (χ(2)=187.87 and p<0.0005) for identifying dysfunctional use (frequent use, abuse and dependence) with a score >2.
  
  
  CONCLUSIONS
  The scale was seen to have great usefulness for psychoactive substance use screening. A cut-off point of 2 differentiated functional from dysfunctional use.
