Treatment Gains from Early and Intensive Behavioral Intervention (EIBI) are Maintained 10 Years Later.

The team tracked kids who finished two years of Early Intensive Behavioral Intervention. They wanted to know if the gains stuck around ten years later.

They checked cognitive scores, daily living skills, and looked for new mental health diagnoses or medication use.

All the early gains in thinking and self-help skills were still there a decade later.

No child had picked up new psychiatric labels or needed new meds.

Kovshoff et al. (2011) looked at the same kids after only two years without extra help. Most skills had faded. The new 10-year data seem opposite, but the kids here got steady parent-run services after the program ended. That extra support likely kept the gains alive.

Reichow et al. (2009) and Howlin et al. (2009) pooled many EIBI studies and saw average IQ and adaptive boosts. This single long cohort now shows those average gains can last if you keep some maintenance plan going.

Rodgers et al. (2021) found small-to-medium effects across 491 kids after two years. The present study says, 'Stick with it—those small wins can still matter ten years out.'

If you run or supervise EIBI, build a hand-off plan before kids leave. Schedule yearly check-ins, train parents to run short booster sessions, and track adaptive scores. A little upkeep beats starting over.
