The diagnostic process:
The diagnostic process includes initial screening performed at the child's doctor's office using initial screening tools such as the MCHAT Modified Checklist for Autism in Toddlers), the PEDS (Parents’ Evaluation of Developmental Status) and the ASQ (Ages and Stages Questionnaires) addition to a full history, developmental history, and a physical examination. Any concerns either expressed by a parent or discovered by the child's doctor should be further evaluated.
The ASRS (Autism Spectrum Rating Scales) is a norm referenced parent questionnaire that provides a detailed analysis with T scores and centiles based on the parent's answers.
The further diagnostic evaluation includes an evaluation by a doctor or psychologist trained in the diagnosis of autism. In addition to the screening tests, and parent reports, a full history including the developmental history and physical examination should be performed.
There are further diagnostic tests that may be performed such as the Autism Diagnosis Interview – Revised (ADI-R), the Autism Diagnostic Observation Schedule (ADOS-2), and the Childhood Autism Rating Scale (CARS).
The diagnostic criteria according to the American Psychiatric Association's Diagnostic and Statistical Manual, Fifth Edition (DSM-5) are used to help diagnose ASD. You can click here to read them: https://www.cdc.gov/ncbddd/autism/hcp-dsm.html.
