NCT ID NCT05663970
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a 6-week virtual group program that teaches parents strategies to encourage their toddler's vocalizations and shared smiling. The program is for children aged 12-42 months who have early signs or a diagnosis of autism or related social communication challenges. Researchers will compare the program to a general child development discussion group to see if it improves child communication and parent skills.

- What this could lead to
- If it works, this could provide an effective, accessible early intervention that helps toddlers with autism or social communication challenges improve their vocal and social skills.
- What could go wrong
- This is a relatively small trial (120 participants) testing a new virtual group format. The program may not work as well as the in-person version, and results may not apply to all families.
