The Ages and Stages Questionnaires, Third Edition (ASQ-3) was developed for use in
pediatric developmental screening to determine the need for further evaluation of
developmental delay.1., 2.
This screening tool is a system of 21 age-specific questionnaires for children 1
to 66 months of age.1., 2.
The ASQ-3 measures 5 developmental domains: gross motor, fine motor, communication,
problem-solving, and personal-social, with items rated as typical development, need
for monitoring, and need for further assessment. A professional or caregiver can complete
the ASQ-3, allowing this tool the potential to be completed by a parent or caregiver
before being seen by a clinician. The ASQ-3 has shown to be a reliable and valid instrument
for determining the need for further developmental evaluation. The ASQ-3 was found
to have excellent test-retest reliability among 4 of the 5 domains measured by the
This measure has shown to have both excellent interrater reliability4
and excellent concurrent validity in children >30 months of age.3
The ASQ-3 has been translated and validated into multiple languages,5
and studies have shown both the disadvantages3
and the effectiveness of the measure when translated and culturally adapted for use
in various countries.6., 7.
