The MIGDAS-2 (Monteiro Interview Guidelines for Diagnosing the Autism Spectrum, Second Edition) is a qualitative, sensory-based diagnostic tool used by clinicians to assess for Autism in children, adolescents, and adults. It includes interview protocols for parents, teachers, and individuals, allowing for a comprehensive and personalised assessment. This approach helps clinicians gather in-depth insights into how a person perceives and interacts with the world and is particularly helpful for people who present with a more internal presentation of Autism. The MIGDAS-2 is a validated tool for Autism assessment.
