Technical Info

What sets ASQ-3 apart? Validity, sensitivity and specificity. To name a few.

ASQ-3’s high validity and reliability have been proven by extensive research. These results underscore the overall effectiveness of ASQ-3 to discriminate between children with developmental delays and those who appear to be developing typically.

• The validity of ASQ-3 has been evaluated extensively. The unparalleled research sample includes 15,138 children that mirror the U.S. population in terms of race, ethnicity, and socio-economic groups.
• The concurrent validity (measured by comparing the percentage of agreement between the results of the parent-completed ASQ-3 questionnaires with the results of professionally administered standardized assessments) ranged from 74% for the 42-month ASQ-3 questionnaire to 100% for the 2-month and 54-month questionnaires, with 86% overall agreement. Concurrent Validity for ASQ-3 questionnaire Intervals.
• The sensitivity* of ASQ-3, or the ability of ASQ-3 to correctly identify those children with delays, ranged from 75% for the 6-month questionnaire to 100% for the 4-month, 14-month, 54-month, and 60-month questionnaires, with 86% overall agreement.
• The specificity* of ASQ-3, or the ability of ASQ-3 to correctly identify typically developing children, ranged from 70% for the 14-month questionnaire to 100% for the 2-month, 16-month, and 54-month questionnaires, with 85% overall agreement.

*Given the complexity of measuring child development, the American Academy of Pediatrics considers high quality developmental screening tests to have sensitivities and specificities of 70% to 80%.

Research & Studies

How reliable? We’ll let the data tell the story.

The validity of ASQ-3 has been studied more than any other screener. Psychometric studies based on a normative sample of more than 18,000 questionnaires show high reliability, internal consistency, sensitivity, and specificity.

The research never stops.

Studies on ASQ-3 are currently being conducted in the United States, Canada, and countries throughout the world. We look to our users to inform the future evolutions of ASQ-3—the educators, families and professionals using our tools on a daily basis. To date, thousands of families and professionals have provided valuable feedback to the tool’s developers at the Early Intervention Program at the University of Oregon.

Our developers are happy to receive blind data to help further their research and the development of future editions. If your program has collected data on ASQ-3 and would like to share it, email . Please include your data and complete contact information, which will be shared only with the authors and not used by Brookes Publishing or any other party.

ASQ-3 and Autism

Identify early signs of autism with ASQ-3.

More children than ever before are being diagnosed with an autism spectrum disorder (ASD)—currently, the CDC estimates that an average of 1 in 68 children in the United States has an ASD.1

Here’s the good news. With early diagnosis and intervention, a child’s chances for social and academic success can be greatly improved.

This is where ASQ-3 comes in. Through its parent-completed questionnaires, educators and professionals get the critical insights need to detect delays or potential delays.

In fact, exciting retrospective research shows that ASQ accurately identified children who were later found to have autism after further assessment. And with ASQ-3’s questions on behavior and expressive language, it’s easier than ever to elicit parent concerns that may indicate autism.

ASQ-3 is a fast and accurate first step in identifying children with autism—and quickly starting the intervention services to truly impact outcomes during these early, critical first years.

Comparison Chart

The pediatric experts have spoken. See how they compare leading screeners.

In an effort to connect professionals with the most effective, accurate screeners, the experts at Pediatrics in Review performed a thorough review of leading screeners. The results are published in its research: “Selecting Developmental Surveillance and Screening Tools.”

Ages & Stages Questionnaires was recommended as a parent report measure to screen both for general developmental delay and for developmental delay in at-risk (such as preterm birth or economically disadvantaged) populations.
