The American Academy of Pediatrics (AAP) recommends routine developmental screenings for young children, with specific attention to autism spectrum disorder (ASD) at 18 and 24 months of age. These screenings are a standard part of well-child visits and aim to identify potential developmental delays or disabilities early on.
Developmental surveillance, an ongoing process of monitoring a child’s development, occurs during regular pediatric checkups at 9, 18, and 30 months, according to the AAP. These screenings are not diagnostic tools, but rather indicators of whether further evaluation is warranted. A positive screening result signals the need for a comprehensive assessment by a healthcare professional.
Several screening tools are utilized to assess children for ASD, each designed for different age groups and settings. The Modified Checklist for Autism in Toddlers (M-CHAT), a parent-completed questionnaire, is used for children between 16 and 30 months. It consists of 20 questions focused on a child’s behavior and can support determine if a professional evaluation is necessary.
For children aged 24 to 36 months, the Screening Tool for Autism in Toddlers and Young Children (STAT) offers an activities-based assessment. Administered by healthcare providers experienced in autism, the STAT evaluates social and communicative behaviors through 12 activities, including play, imitation, and attention-seeking.
The Social Attention and Communication Surveillance (SACS) Tool is designed for children from 12 months through preschool and is administered by educators, psychologists, or other healthcare professionals. It focuses on behaviors characteristic of ASD.
Screening also extends to school-age children. The Social Challenges Screening Questionnaire (SCSQ) identifies children who may exhibit symptoms previously associated with Asperger’s syndrome, now understood as level 1 ASD. This questionnaire is completed by parents, educators, or medical professionals.
For teenagers and adults aged 16 and over, the Autism Spectrum Quotient (AQ) Test is a self-administered questionnaire with 50 questions designed to measure autistic traits.
Research indicates that autism spectrum disorder can sometimes be detected as early as 18 months, and a diagnosis by an experienced professional can be considered reliable by age 2. However, many children receive a final diagnosis much later, potentially delaying access to crucial intervention services.
