Autism Spectrum Assessment

Autism Spectrum Disorder (ASD) describes a group of neurodevelopmental disorders characterised by a) deficits in social communication and b) repetitive/ restricted behaviours and interests, present from the early developmental period.

The Autism Assessment Clinic @ Kidspace offers a unique model of assessing for ASD, which involves the expert opinion of a Child & Adolescent Psychiatrist, as well as a behaviour observation and parent interview conducted by a Child & Adolescent Psychologist.

What assessment tools are used?

  • Psychiatric Assessment: A comprehensive assessment is first conducted by a Child and Adolescent Psychiatrist, who will be able to advise whether he or she recommends further testing for ASD


  • Child Observation: The Autism Diagnostic Observation Schedule – Second Edition (ADOS-2) is a behaviour observation, where the assessing clinician will be interested in how your child interacts with him or her (i.e., an unfamiliar adult). The ADOS-2 is considered the most reliable diagnostic instrument designed to assess for ASD


  • Parent Interview: The Autism Diagnostic Interview Revised (ADI-R) is a clinical interview conducted with parents in order to assist in diagnosing ASD and distinguishing ASD from other developmental disorders


  • Supplementary Assessments: At the time of the Psychiatric Assessment, extra assessments may be recommended if clinically indicated (e.g., intellectual assessment, ADHD assessment)
