Autism assessments have historically been shaped by clinical frameworks that, while useful, often fail to centre the autistic perspective.

In recent years, however, a more affirming and individual-focused approach has emerged: the MIGDAS (Mutual Interview Guide for Diagnosing and Assessing Autism Spectrum) method. Rooted in respect, understanding, and authenticity, MIGDAS offers a refreshing alternative to traditional diagnostic models.

What Is MIGDAS?

MIGDAS is a qualitative assessment tool designed to engage autistic individuals in a meaningful, conversational way. Unlike many conventional diagnostic methods, which can feel clinical and impersonal, MIGDAS prioritises the unique experiences and perspectives of the individual. By creating a comfortable, sensory-friendly environment, MIGDAS enables assessors to build rapport and gain a deeper understanding of the individual’s inner world.

A Neuroaffirming Approach

Traditional autism assessments often focus on deficits, using language that can feel pathologising or stigmatising. MIGDAS turns this paradigm on its head by emphasising strengths and embracing neurodiversity. Through its structured yet flexible framework, MIGDAS celebrates individuality, viewing differences in communication, behaviour, and sensory preferences as natural variations rather than problems to be fixed.

The Process

The MIGDAS assessment begins with a sensory-based interview that encourages the individual to share their preferences and experiences. By focusing on sensory interests and comfort items, the process becomes less intimidating and more engaging. Assessors observe and document behaviours, communication styles, and sensory preferences in a way that respects the individual’s autonomy.

Family members and caregivers are also invited to contribute insights, ensuring a holistic view of the person’s experiences. This collaborative approach not only aids diagnosis but also helps individuals and their families better understand and embrace their unique neurology.

Why It Matters

For many autistic individuals, traditional assessments can feel overwhelming or invalidating. MIGDAS offers a welcome change by aligning with the principles of neurodiversity, which advocate for acceptance and understanding of neurological differences. By framing autism as a different, not deficient, way of being, MIGDAS fosters a sense of pride and self-awareness in those being assessed.

This shift is particularly important for children, who often internalise negative perceptions of their differences. A neuroaffirming assessment like MIGDAS can help them—and their families—see these differences as sources of strength.

Looking Ahead

The adoption of tools like MIGDAS marks a crucial step towards more inclusive and respectful practices in autism diagnosis. It reflects a broader cultural shift towards understanding and celebrating neurodiversity, moving away from deficit-focused models and towards a more compassionate approach. Several of our team members are trained in the MIGDAS, as well Dr Goldsmith runs the international peer supervision group for MIGDAS and has regular consultation with the Founder. It provides Foundations a more deeper look at an individual's experience that ADOS and other tools might not pick up, especially in females.
