ASQ:SE-2 is a parent-completed screening tool used to identify young children aged 1-72 months who may be at risk for social or emotional difficulties. It screens seven key behavioral areas and was developed as a complement to the Ages & Stages Questionnaires developmental screening tool. The second edition was published in 2015 and includes expanded age ranges, new data and cutoffs, and additional items to help identify autism and communication issues. Parents complete a questionnaire for their child's age level which takes 10-15 minutes. Scores are then used to identify children in need of further assessment.
