Current Research
Thousands of families have completed ASQ questionnaires, and professionals using the questionnaires have provided valuable feedback to the tool’s developers at the Early Intervention Program at the University of Oregon. As programs make the transition to ASQ-3, the developers will be 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 rights@brookespublishing.com. 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.
