The parent-completed Ages & Stages Questionnaires, Third Edition (ASQ-3) is the most accurate, family-friendly way to screen children for developmental delays between one month and 5½ years, without any gaps between the questionnaire age intervals. Recommended by top organizations such as the American Academy of Neurology, First Signs, and The Child Neurology Society*, ASQ-3 is highly valid and reliable. ASQ-3’s questions on behavior and communication also help elicit parent concerns that may point to autism.
ASQ-3 questionnaires
- are available in Arabic, English, French, Spanish or Vietnamese
- take just 10–15 minutes for parents to complete and 2–3 minutes for professionals to score
- capture parents’ in-depth knowledge
- highlight a child’s strengths as well as concerns
- teach parents about child development and their own child’s skills
- highlight results that fall in a “monitoring zone,” to make it easier to keep track of children at risk
- can be completed at home, in a waiting room, during a home visit, or as part of an in-person or phone interview
