Assessment & Research

Assessing change in early intervention programs for children with autism.

★ The Verdict

Stop assuming the whole package works—start testing the single parts you actually deliver.

✓ Read this if BCBAs running or supervising comprehensive early-intervention classrooms.
✗ Skip if Clinicians who only do one-to-one DTT and already graph each skill.

01Research in Context

01

What this study did

Kasari (2002) read every big early-intervention study for preschoolers with autism. She did not run new kids; she told a story about what was missing.

She asked one question: Do we really know which parts of these thick, pricey programs make kids better?

02

What they found

The answer was no. Most papers treated the whole package as a black box. They counted IQ or language at the end but never tracked which teaching move caused the jump.

Without that link, we can’t tell parents why therapy works or trim the parts that don’t.

03

How this fits with other research

Egli et al. (2002) looked at the same pile of studies the same year. They used a stricter checklist and reached the same bleak view: most tools were weak and no one measured the middle steps.

Matson (2007) picked up the baton five years later. The message got sharper: pick the wrong ruler and even a so-so program can look like a cure.

Eckes et al. (2023) finally crunched the numbers Connie wanted. Eleven solid trials showed medium gains in IQ and daily skills, but language and parent stress stayed flat. The box opened a crack: ABA works for some things, not everything.

04

Why it matters

Next time you praise a comprehensive program, pause. Ask which slice you can credit: discrete trials, peer play, parent coaching? Track that slice with a quick daily probe. If it climbs, keep it; if not, swap it out. Connie’s plea is now your Monday-morning scalpel.

03Original abstract

Assessing the efficacy of any intervention can be a difficult task. In the case of children with autism who require comprehensive and long-lasting interventions, the task becomes even more difficult. In this paper, intervention studies based on comprehensive interventions for young children with autism are reviewed and examined in reference to elements that are essential to a well-designed treatment study, e.g., randomization/matching procedures, and outcome measures. Given the complexity of these comprehensive intervention programs, and the few data available on interventions with clear empirical validation, a plea is made for studies to consider the active ingredients or component parts of an intervention, e.g., number of hours, type of setting, and teaching approach. Suggestions are further made for improving future studies, including more rigorous designs, and measuring change.
