Autism Assessments in Newcastle – A Guide for Families from a Psychologist
Accessing an autism assessment can sometimes feel overwhelming. At Mind & Health Psychology, we offer structured, evidence-based autism assessments for children, adolescents, and adults, conducted in Newcastle (Eastlakes Medical Centre) and Sydney (Chatswood). Our assessments are consistent with current clinical guidelines and suitable for NDIS documentation where relevant. This article outlines our process, the tools we use, and our commitment to neuroaffirming practice.
What Is Included in an Autism Assessment?
We use a comprehensive battery of validated tools. Depending on age and presentation, the assessment may include:
ADOS-2 – Autism Diagnostic Observation Schedule (a semi-structured behavioural observation)
ADI-R – Autism Diagnostic Interview–Revised (with parents or caregivers)
MIGDAS-2 – Monteiro Interview Guidelines for Diagnosing Autism Spectrum
Cognitive assessment – using the Wechsler scales, Stanford-Binet, or other appropriate developmental tools
Clinical behavioural observation and developmental review
Understanding the Tools We Use
ADOS-2 (Autism Diagnostic Observation Schedule – Second Edition)
This semi-structured observational tool assesses social communication and interaction through interactive tasks. It is suitable for individuals aged 12 months through adulthood and is adapted based on language ability.
ADI-R (Autism Diagnostic Interview – Revised)
The ADI-R is a structured clinical interview conducted with caregivers, exploring early development, communication, play, social interaction, and restricted behaviours. It is particularly useful when a developmental history is required for diagnosis.
MIGDAS-2
The MIGDAS-2 provides a sensory-based and narrative-driven framework that complements the ADOS-2 and ADI-R. It emphasises authentic communication, sensory interests, and individual differences, and is particularly helpful for individuals who may find structured assessments challenging.
How These Tools Work Together
Using both the ADOS-2 and ADI-R allows for a comprehensive understanding of both present behaviours and developmental history. The MIGDAS-2 adds qualitative insights and supports a more person-centred understanding of autism characteristics. This triangulated approach helps inform diagnostic formulation.
Cognitive and Developmental Assessments
Cognitive testing supports diagnosis by clarifying verbal/non-verbal strengths, reasoning skills, learning profiles, and adaptive functioning. Depending on age and developmental level, we use:
Wechsler Intelligence Scales (for school-aged children and adults)
Stanford-Binet Early Version or Rossetti Infant-Toddler Language Scale (for younger children)
These assessments also allow for observational insight into problem-solving, communication, and task engagement.
About the Practitioner
All autism assessments at Mind & Health Psychology are conducted by a Registered Psychologist. Stephen O’Malley has undertaken postgraduate training in Clinical Neuropsychology and is a Board Approved Supervisor. He is formally certified in the use of the ADOS-2, ADI-R, and MIGDAS-2 and other Cognitive and Language measures.
What Happens After the Assessment?
Following the assessment:
A feedback session is conducted to discuss the findings and provide clarification
A Comprehensive written report is provided, suitable for health professionals, NDIS, and educational or therapeutic planning.
Final Considerations
Autism is a form of neurodiversity that presents uniquely across individuals. Our assessments aim to offer a structured and affirming understanding, consistent with best-practice guidelines and the ethical standards of the Psychology Board of Australia.
