About#

The Autism Observation Scale for Infants is a structured, examiner-administered observational assessment designed to detect early behavioral markers associated with autism spectrum disorder in infants, typically between 6 and 18 months of age. It evaluates domains such as visual attention, social engagement, motor behavior, sensory responses, and early communication. The AOSI provides a quantitative summary score reflecting the presence and severity of autism-related behaviors.
