Summary

This study tested JASPER, a play-based therapy for autism, in 84 toddlers aged 18 months to 5 years. Children were randomly assigned to receive JASPER from a clinician or their parent. The goal was to see if two new measurement tools (BOSCC and ELSA-T) could track changes in social communication and language. The study focused on improving how we measure progress, not on finding a cure.

What this could mean

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

Active substance
JASPER (a play-based behavioral therapy)
What this could lead to
If successful, this could provide better ways to measure social communication changes in young children with autism, helping future therapy trials.
What could go wrong
This is an early-stage study focused on measurement tools, not a treatment trial. The results may not apply to all children with autism.
