Ages and Stages Questionnaire: a global screening scale

Abstract

With standardized screening tools, research studies have shown that developmental disabilities can be detected reliably and with validity in children as young as 4 months of age by using the instruments such as the Ages and Stages Questionnaire. In this review, we will focus on one tool, the Ages and Stages Questionnaire, to illustrate the usefulness of developmental screening across the globe.
