Baby Siblings of Children with Autism

Last Updated: Thursday, September 17, 2015

Principal Investigator: Paul J. Yoder, Ph.D.


We are interested in learning more about early development in baby siblings of children with Autism Spectrum Disorder (ASD). Research shows that younger siblings of children with autism have a greater risk of autism or of social communication and language delay.

Study Details

All participants come to the Kennedy Center for a series of assessment appointments, every 3 months over a 9-month period.

All younger siblings receive standardized developmental testing, psychological assessment for autism, and a formal written report of testing results, including recommendations and referrals at no cost.

Some participants receive training in communication strategies to use at home with their children.

Participant Criteria

Children who are 12 to 18 months old who have an older sibling with a diagnosis of Autism Spectrum Disorder.


All families will receive $200 at the end of the study.
