What Is the ASQ Autism Screening? 

Author: Lucia Alvarez, MSc | Reviewed by: Dr. Rebecca Fernandez, MBBS

The ASQ autism screening (Ages and Stages Questionnaire) is a widely used tool designed to assess developmental milestones in young children, helping to identify potential early signs of autism spectrum disorder (ASD). It is a developmental screening tool that allows parents and healthcare providers to monitor a child’s growth and detect delays in areas such as communication, social interaction, and motor skills. The ASQ provides a structured format for parents to report on their child’s behaviour and development, guiding professionals toward potential autism indicators. 

The ASQ autism screening is typically used for children aged 1 month to 5½ years and includes a series of questions in the form of a parent questionnaire. Parents answer questions related to their child’s behaviour and skills, which are then reviewed by healthcare providers to determine if further evaluation is needed. 

How the ASQ Autism Screening Works 

Here’s how the ASQ autism screening operates: 

Ages and Stages:

The Ages and Stages portion of the ASQ focuses on age-appropriate milestones and behavioural expectations. By comparing the child’s progress against these stages, healthcare providers can assess whether the child is on track developmentally or if delays in specific areas are evident. 

Developmental Screening:

The developmental screening tool includes questions related to communication, social interactions, and play, which are important areas to assess when considering autism. Delays in language development, limited social engagement, and difficulty with pretend play are all signs that warrant further investigation. 

Parent Questionnaire:

The parent questionnaire is a critical part of the ASQ. It gathers first-hand information about the child’s behaviour in everyday settings, offering a reliable insight into how the child engages with their environment and others. 

The ASQ autism screening is a helpful first step in identifying potential autism concerns, allowing for early intervention and support. For expert advice and personalised consultations, visit providers like Autism Detect for guidance and the next steps in your child’s developmental journey.
