The Childhood Autism Rating Scale 2nd ed. (CARS2) helps to identify children with autism and determine symptom severity through quantifiable ratings based on direct observation, for children aged 2 years and above.
It includes two 15-item rating scales completed by the clinician (each designed for a different population-Standard and High Functioning); and an unscored Parent/Caregiver Questionnaire, that gathers information for use in marking the Standard and High Functioning ratings.
The CARS2 Questionnaire for Parent/Caregiver in an unscored form that is completed by the parent or caregiver of the individual being assessed. Its purpose is to give the clinician more information on which to base CARS2 Standard and High Functioning ratings. Often the questionnaire serves as the framework for a follow-up interview, during which the clinician can clarify and interpret the responses provided by the parent or caregiver.
The areas covered include the individual's early development; social, emotional, and communication skills; repetitive behaviours; play and routines; and unusual sensory interests.
