The Childhood Autism Rating Scale (CARS) is a tool used by healthcare professionals to identify and diagnose autism spectrum disorder (ASD) in children. However, there are several other synonyms for CARS that are also commonly used. One such term is Autism Diagnostic Observation Schedule (ADOS), which is another assessment tool used to evaluate ASD. Another synonym is the Autism Spectrum Screening Questionnaire (ASSQ), which is a questionnaire based tool used to assess the presence of ASD symptoms in children. Another commonly used term is the Social Communication Questionnaire (SCQ), which is a screening tool that measures symptoms of ASD. Other synonyms include the Autism Behavior Checklist (ABC), and the Autism Diagnostic Interview-Revised (ADI-R). Overall, these tools are crucial in the diagnosis and early intervention of ASD in children.
