Autism spectrum disorder (ASD) diagnosis is a multifaceted process that doesn’t rely on a single medical test like a blood test or genetic test. Instead, diagnosing autism involves a comprehensive evaluation by experienced healthcare professionals. This assessment includes examining an individual’s developmental history and behavior, conducting interviews with the person and their family, and utilizing specialized screening and diagnostic tools.
While only qualified health professionals can provide an official autism diagnosis, various screening tools are available that can highlight potential autism symptoms for parents, caregivers, and individuals themselves. Early autism screening is crucial as it can significantly improve access to necessary services and support, positively influencing the long-term outcomes for individuals with autism.
The screening tools detailed below are designed to help identify both children and adults who might have ASD. It’s important to remember that this is not an exhaustive list, and other screening tests exist. Crucially, a positive result from a screening tool is not a diagnosis of autism. If a screening indicates potential ASD, it must be followed by a thorough diagnostic evaluation conducted by a healthcare professional.
Autism Screening Tools: Identifying Potential ASD
Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R)
Recommended for children aged 16 to 30 months
The M-CHAT-R is a freely available questionnaire completed by parents. It consists of 20 questions focused on different aspects of a toddler’s behavior. Parents can use the results of this initial autism screening to discuss any concerns they might have about their child’s development with a healthcare provider. Access the 2-minute screening questionnaire.
Social Attention and Communication Surveillance, Revised (SACS-R) and SACS-Preschool (SACS-PR) Tools
Designed for children between 12 to 60 months old
Developed by La Trobe University, the SACS-R and SACS-PR are autism screening tools aimed at identifying behaviors characteristic of autism spectrum disorder in young children, starting as early as 12 months and extending through the preschool years. These tools are designed to be administered by trained professionals such as psychologists, early childhood educators, and allied health professionals.
Social Challenges Screening Questionnaire (SCSQ)
Intended for school-aged children
The Southwest Autism Research & Resource Center (SARRC) developed the 15-question Social Challenges Screening Questionnaire. This tool can be used by parents, educators, and medical professionals to identify school-aged children who may exhibit symptoms consistent with what was previously known as Asperger syndrome, now categorized as level 1 ASD. Take the Social Challenges Screening Questionnaire.
Autism Spectrum Quotient (AQ) Test
For individuals aged 16 years and older
The Autism Spectrum Quotient Test is a self-administered questionnaire featuring 50 questions. It’s designed to measure the degree of autistic traits in adolescents and adults aged 16 and above with an IQ over 80. Take the Autism Spectrum Quotient Test.
