What's included?

Parts of the Adult Autism or ADHD Assessment

Pre-Session Online Questionnaires

A set of targeted, evidence-based questionnaires. These include screeners for common signs and experiences of adult Autism and/or ADHD, and a structured background questionnaire. This step usually takes around 1.5 to 2.5 hours and is completed at your own pace. It is essential for targeting the diagnostic session specifically to your needs.

Diagnostic Assessment Session (Online)

These are structured clinical interviews using internally recognised, gold standard diagnostic tools:

Autism Assessment

A 2-hour session using the MIGDAS-2 (Monteiro Interview Guidelines for Diagnosing the Autism Spectrum, Adolescent/Adult version, Second Edition). This tool is often preferred by Autistic people for its strengths-based style.

ADHD Assessment

A 2-hour session using the DIVA-5 (Diagnostic Interview for ADHD in Adults), a structured assessment tool considering symptoms across both childhood and adulthood. It has been validated in multiple languages and international studies.

Each section has an explanation of your strengths, potential challenges and recommended tools to build your personal toolkit.

A Right Fit for You?

Adult Autism and ADHD assessments are a significant investment of time, energy, and money, so it’s important to choose an approach that matches your needs and style. 

This approach is structured and efficient. Pre-session questionnaires are used to gather key information upfront, so the session can focus on clarity and confirmation. It’s faster overall but does require some independent work ahead of time.

Check below if this style suits your needs.

A right fit if you:

Need a comprehensive, fast-tracked assessment using gold-standard diagnostic tools

Prefer online sessions over in-person appointments

Are able to complete 2.5–3.5 hours of pre-session questionnaires independently

Are looking for a clear understanding of your strengths, challenges, and blind spots, regardless of diagnosis

Appreciate having two outputs: a plain-language Neurodiversity Guide for your own personal insights, and a formal diagnostic report summary that is suitable for sharing in professional or official contexts

Are prepared to invest time, focus, and financial resources to get structured answers

Crossed-out circle icon indicating that this structured adult Autism and ADHD assessment process may not suit all preferences or support needs.

Not a right fit if you:

Are looking for long-term therapy, open-ended exploration, case management, or connection with local services

Need a functional assessment for government services (e.g. NDIS, DSP, Centrelink)

Are only seeking an ADHD diagnosis for medication (this can only be done by a psychiatrist, so they’re the most appropriate assessors for that)

Prefer in-person attendance over online sessions

Prefer talking things through in real time rather than completing questionnaires independently

Would rather space the process out over several months, with more time to prepare and reflect between each step
