The purpose of this research study is to test how well a common, standardized quality of life tool measures quality of life among children on the autism spectrum who are minimally verbal or have an intellectual disability. Parents/ caregivers of autistic children (ages 5-17) who are minimally verbal or have an intellectual disability are eligible to participate in the study.About 35% of children on the autism spectrum also have an intellectual disability, so it is important to include families with autistic children who are minimally verbal and/or have intellectual disability in research.
