title: [Assessment of attention deficit hyperactivity: SNAP-IV scale adapted to Argentina].
abstract: OBJECTIVE
  Assess the usefulness of the SNAP-IV scale as an instrument for detecting attention deficit hyperactivity disorder (ADHD) in Argentine children aged 4 to 14 years.
  
  
  METHODS
  The SNAP-IV scale was adapted and administered to a group of 1 230 schoolchildren in the province of Buenos Aires, Argentina. The diagnosis was determined with the clinical control, based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. The sensitivity and specificity, as well as the cut-off scores for the SNAP-IV scale in the population studied, were determined.
  
  
  RESULTS
  The score on the SNAP-IV scale with the best correlation between sensitivity and specificity was established in order to determine the true positive cases that in fact had a clinical diagnosis. The cut-off scores obtained were: 1.66 (15/27 points) for the attention deficit subscale and 1.77 (16/27 points) for hyperactivity/impulsivity in the population studied.
  
  
  CONCLUSIONS
  The SNAP-IV scale for detection of ADHD is considered to be valid in the population studied as long as the cut-off scores are modified to obtain the best sensitivity/specificity ratio based on the cultural and socioeconomic features of the population.
