title: Adaptation of the Child Development Clinical Risk Indicators instrument to retrospective parent report.
abstract: OBJECTIVE
  To adapt the Child Development Clinical Risk Indicators (IRDI) instrument to retrospective report for parents of children from 3 to 7 years old and administer it in two groups.
  
  
  METHODS
  Participated on the study 72 subjects--parents of children aged from 2 years and 11 months to 7 years and 7 months--divided into two groups: Research Group and Control Group. The proposed modification to parent report transformed the 31 indicators (affirmations) into retrospective self-administered questions to parents, with responses in Likert scale. The IRDI-questionnaire was administered in the two groups.
  
  
  RESULTS
  The IRDI-questionnaire showed to be easy and quick to administer (average 15 minutes) and with low cost. The analysis of the questions obtained a good internal consistency value. The comparison between the groups by the parents' answers to the 31 questions showed difference in 16 questions.
  
  
  CONCLUSIONS
  The items of the IRDI-questionnaire concern the main Autism Spectrum Disorders risk signs pointed out in literature. The parents' answers showed differences between the studied groups.
