title: Normative ADHD-RS-Preschool Data in a Community Sample in Spain.
abstract: OBJECTIVE
  The objective was to obtain normalized data from the ADHD Rating Scale-IV-Preschool Version (ADHD-RS-IV-P) in a Spanish sample.
  
  
  METHODS
  We translated and adapted the ADHD-RS-IV to our culture to obtain normalized data from a random representative sample of 1,426 Spanish preschool children (3 to <7 years old; 49.7% males). To analyze differences between evaluators, we used MANOVA. Internal consistency was assessed via Cronbach's alpha.
  
  
  RESULTS
  The mean age was 4.7 years old. There was a significant sex effect. The questionnaire had an internal consistency between .86 and .96 according to subscale and evaluator.
  
  
  CONCLUSIONS
  To evaluate ADHD in preschool children, it is necessary to use scores standardized by sex. Using a validated scale in schools and primary care centers may be useful for early detection of ADHD.
