Summary

This study looks at when to start a parent coaching program called JASPER Babble for infants who have an older sibling with autism, putting them at higher risk. About 140 babies will join at 6-8 months old and be randomly assigned to start coaching at 9, 12, or 15 months. Researchers will track their language and communication skills up to age 2 to find the best timing for support.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
JASPER Babble parent coaching
What this could lead to
If successful, this could show the best age to start early coaching for infants at risk of autism, leading to better language and communication skills.
What could go wrong
This is an early-stage study with only 140 infants, so results may not apply to all families. The coaching may not improve outcomes more than standard monitoring.
