Children who screen positive for autism at 2.5 years and receive early intervention: a prospective naturalistic 2-year outcome study
For toddlers picked up by community screening, the kind of early-intervention package did not drive two-year adaptive gains.
01Research in Context
What this study did
Researchers in Australia followed toddlers who screened positive for autism at age 2.5. They tracked the kids for two years while families picked any early-intervention mix they wanted. Some families chose home-and-preschool ABA. Others chose home-only ABA or eclectic blends.
The team wanted to know if the kind of program predicted how well the children did later.
What they found
After two years, the label on the program did not matter. ABA, eclectic, or mixed plans all led to similar adaptive scores. Kids varied a lot, but the style of service was not the reason.
Group averages stayed flat; individual paths bounced around.
How this fits with other research
Vinen et al. (2018) checked the same Australian kids at school age and still found no winner between ESDM and eclectic care. The null result simply lasts longer.
Tsiplova et al. (2023) ran a big Canadian registry study and also saw zero adaptive boost from preschool behavioral services. Three different samples, same blank scoreboard.
Haglund et al. (2020) looks like a clash: Swedish preschoolers in community NDBI did show small ADOS gains. The difference is tiny, the kids were older, and the tool measured autism symptoms, not daily living skills. Measure change, not just program name, when you compare.
Why it matters
Stop selling families on brand names. Focus on the child's progress each quarter. Track individual goals, celebrate tiny wins, and switch tactics when data flat-line. The program label is less important than the daily response you see in session.

03Original abstract
Previous research has stressed the importance of early identification and intervention for children with autism spectrum disorders. Children who had screened positive for autism at the age of 2.5 years in a general population screening and then received a diagnosis of autism spectrum disorder were enrolled in an intervention program provided by Swedish habilitation services. The following interventions were available: a comprehensive intervention based on Applied Behavior Analysis – Intensive Learning (IL) – in two settings, which included home- and preschool-based (IL Regular) and only home-based (IL Modified) and eclectic interventions. There was considerable variability in terms of outcome, but intervention group status was not associated with any of the chosen outcome variables. The main finding was that the type of intervention was not critical for outcome of adaptive or global functioning. The variability in outcome demonstrates the need for continuous assessments and evaluation of the child’s function and behavior throughout the intervention period.
