Early Identification of ASD in Young Children
A Training Model for the Diagnosis of Autism in Community Pediatric Practice, by Zachary Warren and Wendy Stone, was published in the October 2009 issue of the Journal of Developmental & Behavioral Pediatrics.
The Centers for Disease Control and Prevention (CDC), in collaboration with national partners, is hosting a public awareness campaign entitled Learn the Signs, Act Early. The campaign is meant to help parents and child care providers learn more about early childhood development, including potential early warning signs of autism and other developmental disabilities. Building on the success of this campaign, in February 2008 and March 2008, selected states were invited to attend Act Early Regional Summits for the purpose of developing Act Early Plans to enhance their capacity to identify children with ASD earlier and provide evidence-based intervention.
Autism Speaks, Florida State University's FIRST WORDS Project and First Signs have developed a Web-based ASD Video Glossary for parents of children suspected of or recently diagnosed with autism and for professionals who do not have experience in diagnosing young children with Autism Spectrum Disorders (ASD). It contains hundreds of video clips contrasting behaviors that are red flags for ASD with behaviors that are typical.
A promising practices report from the Centers for Medicare and Medicaid Services entitled California – Single Process for Diagnosis and Service Delivery (2007) describes one-stop clinics in California that have been established to diagnose ASD and start services as early as possible. Findings from an evaluation of these clinics show a four-month reduction in the average age of ASD diagnosis.
A Webcast entitled Screening for Autism and the Management of Neurobehavioral Comorbidities: A Primer for General Pediatricians (2007) has been released by the Advanced Studies in Medicine Program at Johns Hopkins University in collaboration with Autism Speaks. It is meant to help pediatricians and other health professionals better understand the signs and symptoms of autism. It is not meant to be used by parents or other caregivers to diagnose autism in their own children.
Materials from the National Conversation on Developmental Screening: Promising Practices for Coordination of Services (June 21, 2007) conference call are available online. This call was sponsored by the National Medical Home Autism Initiative (NMHAI) in collaboration with the American Academy of Pediatrics(AAP) and the National Early Childhood Technical Assistance Center (NECTAC).
