Learning through interaction in children with autism: preliminary data from asocial-communication-based intervention.
Two hours of parent play coaching each week can grow toddler social skills even when language scores stay flat.
01Research in Context
What this study did
Researchers tested a parent coaching program for toddlers with autism. Parents learned to build social moments into daily play. The team ran a year-long randomized trial against usual community services.
Families got two hours of coaching each week. Therapists visited homes and showed parents how to wait, smile, and respond to tiny social bids.
What they found
After twelve months, coached toddlers showed bigger social gains than the control group. They looked, shared, and played with adults more often.
Surprise: standard language test scores did not move. Social skills grew even though words did not.
How this fits with other research
Klusek et al. (2022) later ran the same idea in the real world. Their 12-week Social ABCs rollout also boosted language and social skills. The 2013 study found social-only gains; the 2022 study found both. The gap likely comes from different yardsticks—2013 used standard language tests, 2022 used parent checklists.
Rouhandeh et al. (2022) squeezed the program into four weeks. Toddlers still gained social and language skills. Shorter, lighter doses can work if you track everyday communication instead of clinic tests.
de Jonge et al. (2025) refined the model further. Their Pathways trial coded tiny engagement states minute-by-minute. They saw small but real jumps in joint engagement, echoing the 2013 social boost while still skipping raw word counts.
Why it matters
You can coach parents in natural play and see social growth without waiting for language. Use brief, low-dose visits if you track real-life communication. Pick parent checklists or engagement codes over standard language tests to catch early change.

03Original abstract
The study evaluates a social-communication-based approach to autism intervention aimed at improving the social interaction skills of children with autism spectrum disorder. We report preliminary results from an ongoing randomized controlled trial of 51 children aged 2 years 0 months to 4 years 11 months. Participants were assigned to either a target treatment or community treatment group. Families in the target treatment group were given 2 hours of therapy and coaching each week in an intervention emphasizing social-interaction and the parent-child relationship. Children in the community treatment group received a variety of services averaging 3.9 hours per week. After 12 months, outcomes were measured to determine changes in the groups in social interaction and communication. In addition, a regression analysis was conducted to determine whether changes in social interaction skills were associated with language development. Results suggest that children in the treatment group made significantly greater gains in social interaction skills in comparison to the community treatment group, but no between-group differences were found for standard language assessments. Initiation of joint attention, involvement, and severity of language delay were found to be significantly associated with improvement of language skills in children with autism. Finally caregiver skills targeted by the intervention were found to be significantly associated with changes in children's interaction skills.
