What is an M-CHAT-R?

During infancy and early toddlerhood, many children with autism may display distinct developmental variations, particularly in social and language abilities.

While they may achieve typical milestones such as sitting, crawling, and walking on schedule, there could be delays or distinctive patterns in their spoken language and peer interactions.

The Modified Checklist for Autism in Toddlers, M-CHAT-Rs are used as a screening tool to assess your child's behavior through 20 thoughtfully crafted questions. Specifically created for toddlers aged 16 to 30 months, this screener aims to identify potential signs of autism.

Upon completion, the results of the M-CHAT-R will provide you with valuable insights. If necessary, it will indicate the potential need for further evaluation. This early detection can be instrumental in understanding your child's development and addressing any concerns promptly.

Armed with the screener's results, you'll have a concrete basis to discuss any worries or observations you might have about your child's behavior with their healthcare provider. This opens up an essential avenue for communication, ensuring that your child receives the appropriate care and support they may need, fostering their well-being and development.
