What is the Ages and Stages Questionnaire?
The Ages and Stages Questionnaire (ASQ) is a global developmental screener that healthcare providers use to assess a child's communication, fine motor skills, problem-solving, and personal-social skills. It is designed for children between 1 month and 5 ½ years old. The ASQ comprises a series of questions that parents or caregivers answer about their child's abilities and behaviors. The questions are divided into different age ranges and cover various skills.
The ASQ is important for identifying a potential developmental delay or disability in young children. The assessment of earlier development enhances the possibility for a child to achieve their maximum potential. Developmental psychologists Diane Bricker and Jane Squires, authorities in early childhood development, developed the ASQ (Ages and Stages Questionnaire, 2015). The questionnaire has been translated into several languages and is used by healthcare professionals globally.
