Brief Report: An Exploratory Study of the Diagnostic Reliability for Autism Spectrum Disorder.

Previous research shows inconsistency in clinician-assigned diagnoses of Autism Spectrum Disorder (ASD). We conducted an exploratory study that examined the concordance of diagnoses between a multidisciplinary assessment team and a range of independent clinicians throughout Australia. Nine video-taped Autism Diagnostic Observation Schedule (ADOS) assessments were collected from two Australian sites.

Diagnostic evaluation for autism spectrum disorder: a survey of health professionals in Australia.

Objectives: There is currently no agreed Australian standard for the diagnosis of autism spectrum disorder (ASD) even though there are specific diagnostic services available. We suspected inconsistency in the diagnostic practices of health professionals in Australia and aimed to assess these practices across the nation by surveying all relevant professional groups.

Design: In this study, we completed a survey of 173 health professionals whose clinical practice includes participating in the diagnostic process for ASD in Australia.
