Ages and Stages Questionnaire (ASQ)

Caregiver-report questionnaire to determine the extent to which children aremeeting or missing key developmental milestones in a variety of domains frombirth through 6 years-of-age.  The ASQ spans five areas of development: communication,gross motor, fine motor, problem solving, and personal-social interaction.  Distinct versions are available for different age groups, with some continuityto the content, even as the specific items change to keep pace with children’sdevelopment.   Forms can be completed byparents or by other caregivers (e.g., daycare workers) familiar with thechild’s behaviors. Items are constructed using simple vocabulary and grammar,as well as concrete scenarios or examples of child behavior that could beplausibly be observed in many settings.  The measure requires just 10-15 minutesto complete and 2-3 minutes to score.  Cut-off scores allow for theidentification of children with potential areas of delay.  Evidence supports thetest-retest reliability, inter-rater reliability, and internal reliability ofthe measure, as well as its concurrent validity with widely used directassessments of children such as the Bayley Mental Development Index (see Squires, Twomby, Bricker, & Potter, 2009). The ASQ can be linked to a library of coordinated learningactivities, allowing for the construction of strategic interventions to addressareas of weakness and enhance areas of strength.
