ASQ-3

Also written as: ASQ-3 — Ages and Stages Questionnaires, Third Edition

Ages and Stages Questionnaires, Third Edition, a developmental screening tool used to identify children who may need further assessment.

Full Definition

The Ages and Stages Questionnaires, Third Edition (ASQ-3) is a widely used parent-completed developmental screening instrument designed to identify infants and young children (2 months to 5½ years) who may be at risk for developmental delays. The questionnaire covers five developmental domains: communication, gross motor, fine motor, problem-solving, and personal-social skills. Each age-specific questionnaire contains 30 items that parents can easily complete, making it practical for use in clinical settings, home visiting programs, and early intervention services. The ASQ-3 is considered a reliable first-level screening tool that helps determine which children need comprehensive developmental evaluation.

Usage

Usage note: Always specify the version (ASQ-3) and age interval used. Results should prompt clinical judgment, not replace it.
