Which tool is utilized to screen a child for Autism Spectrum Disorder at 1.5 years old?

• A. M-CHAT questionnaire
• B. ASQ-3 (Ages and Stages Questionnaire)
• C. Childhood Behavioral Checklist
• D. Evaluative Play Assessment

Answer: (A)

The M-CHAT (Modified Checklist for Autism in Toddlers) questionnaire is specifically designed for the early detection of Autism Spectrum Disorder (ASD) in children aged 16 to 30 months, making it highly appropriate for screening at 1.5 years old. The M-CHAT focuses on social and communicative behaviors that are critical for identifying potential signs of autism. Its purpose is to identify children who may benefit from further evaluation, allowing for early intervention, which can significantly improve long-term outcomes for children with autism. The tool is straightforward, relying on parent-reported behaviors to assess developmental milestones relevant to autism. The other tools mentioned, such as the Ages and Stages Questionnaire, Childhood Behavioral Checklist, and Evaluative Play Assessment, have different focuses, such as general developmental milestones or behavioral issues, but are not specifically tailored for the early identification of autism, making them less suitable for the purpose of screening at 1.5 years old.
