What ASQ Users Are Saying

Comparison Chart of Screeners

Selecting the screening tool that best suits your program can be daunting. Numerous tools are out there, but how do you know which one is best for you?

A 2008 Pediatrics in Review article on “Selecting Developmental Surveillance and Screening Tools” summarized a review of the research that was designed to help guide practitioners in the selection of valid screening instruments. The review recommended the Ages and Stages Questionnaires® (ASQ) 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.

In the chart below, see why ASQ is the screener of choice for thousands of programs across the country.

Commonly Used Parent-Report Developmental Screening Tools
Instrument Ages & Stages Questionnaires®,Third Edition (ASQ-3): A Parent-Completed, Child-Monitoring System Denver Prescreenng Developmental Questionnaire (PDQ II) Infant Development Inventory (IDI) and the Child Development Review Parent Questionnaires (CDR-PQ) Parents’ Evaluation of Development Status (PEDS) and PEDS: Developmental Milestones (PEDS:DM)
For use with Children from 1-66 months Children from birth to 6 years Children from birth to 18 months (IDI); and children from 18 months to kindergarten (CDR-PQ) Children from birth to 8 years
Questionnaire items ASQ-3 includes 21 age-specific questionnaires, which allow you to accurately screen anytime between 1 and 66 months—whether at the AAP recommended 9-, 18-, and 24- or 30- month well-child visits, or whenever the child enters your program The PDQ is a 105-item questionnaire regarding a child’s current level of development. At each visit the parent is asked to answer 7-10 age-appropriate questions The IDI includes about 85 developmental milestones divided by month and across 5 domains; the CDR-PQ includes about 100 items divided by month or year and across 5 domains; also includes open-ended questions PEDS is a single questionnaire containing the same 10 open-ended questions for all ages to elicit and address parents’ concerns. PEDS:DM provides 6-8 milestones-type items per well visit
Single stage screener? Yes. Empirically derived cutoff scores produce results that clearly suggest whether to (a) evaluate further, (b) closely monitor, and/or (c) share information with parents about a child’s strengths and recommend activities for healthy development No. Results of the PDQ showing two or more delays produce a referral for further screening with the professionally administered DENVER II. Yes. The results are compared to age norms, and classified as “typical” for age in all areas, or as “borderline” or “delayed” in one or more areas of development Yes, when used in combination. PEDS alone “provides decision-making paths to aid in interpreting parents’ responses to questions.”
Developmental areas screened Communication, gross motor, fine motor, problem solving, and personal-social, plus self-regulation, compliance, language, adaptive behaviors, autonomy, affect, and interaction with people with ASQ:SE Personal and social, fine motor, gross motor, and language Social, self-help, gross motor, fine motor, language Fine motor, gross motor, self-help, expressive language, receptive language, and social-emotional
Sample item The parents answers Yes,Sometimes, or Not Yet: Does your child stack a small block or toy on top of another one? (18-month questionnaire, fine motor area) (sample not available) The parent checks (or doesn’t check)Runs well, seldom falls (2-0 years, gross motor area) The parent circles No,Yes, or A Littleand adds comments: Do you have any concerns about how your child talks and makes speech sounds?(expressive language and articulation area)
Time to complete and score 2-3 minutes to score. Once parents complete the questionnaire (10-15 minutes), the professional consults a scoring grid with clearly designated results 2-12 minutes IDI: 5-10 minutes CDR: 10-20 minutes 2-10 minutes
Standardization Standardized in an unparalleled national sample of 15,138 children Drawn from the DENVER II, which was normed on 2096 children in Colorado; diversified in terms of age, place of residence/
ethnicity/cultural background, and maternal education
IDI: Studied in 86 high-risk 8-month olds seen in a perinatal follow-up program and compared with the Bayley scales; CDR: Standardized with 220 children aged 3-4 from primarily white, working class families in south St. Paul, MN Standardized with 771children from diverse ethnic and socioeconomic backgrounds, including Spanish speaking
