Observational StudyDetection of ASD at the 1st Birthday as Standard of Care: The Get SET Early Model

According to a recent report from the Centers for Disease Control, most children with ASD do not receive a diagnosis and begin receiving treatment until well after their 4th birthday, which is unfortunate given that many connections between brain cells have already been established by that age. This program will test a model called Get S.E.T. Early (S=Screen, E=Evaluate, T=Treat) in both San Diego and Phoenix, designed to detect, evaluate, and treat ASD within the first 2 years of life. In this proposal 7,500 toddlers from the general population will be screened in San Diego and Phoenix (total 15,000) using the CSBS IT Checklist (Wetherby \& Prizant, 2002) at well baby check-ups using a "triple screen" approach wherein toddlers are screened at three ages starting at 12 months. Investigators predict that providing screening tools with clear cut-off scores and guidelines for automatic referral for both evaluation and treatment will result in dramatically lowering mean age of detection in Phoenix from 4-5 years down to 1-2 years. Investigators also predict that using repeat screening at 12, 18, \& 24 months in combination with automatic referral options via technology (i-Pads) will result in an increase in the number of ASD toddlers detected by 24 months relative to a single time point screen using traditional paper screens.
