A selective overview of issues on classification, causation, and early intensive behavioral intervention for autism.

Temple et al. (2001) wrote a narrative review about autism and early intensive behavioral intervention. They talked about how doctors decide who has autism. They also explained why starting ABA early is important.

The paper did not run a new experiment. It summed up what was known in 2001. It told readers that comprehensive ABA is the way to go for young kids with autism.

The review found no fresh numbers. Instead, it stated that early intensive behavioral intervention is still the top choice. It warned that every child is different, so programs must be tailored.

In short, the paper gave a green light to early ABA while urging teams to watch each child's unique profile.

Eikeseth (2009) later graded 25 studies and agreed: behavioral early programs hold the strongest evidence for preschoolers. This backs up the 2001 endorsement with a wider lens.

Matson (2007) extends the story by throwing a yellow flag. That review says the tools we pick to measure progress can make results look better than real life. So the cheer in Temple et al. (2001) needs a measurement check.

Kasari (2002) also extends the call, telling us to stop treating whole programs like black boxes. We should test which parts actually help, something the 2001 paper did not dig into.

Yazdani et al. (2020) adds another caution: studies that exclude lots of kids often show bigger gains. This tempers the sunny view from 2001 and tells clinicians to read fine print before buying hype.

For BCBAs, this paper is a history marker: it shows when the field locked in on early intensive ABA. Pair it with later reviews to see both the promise and the pitfalls. Use it to justify early starts, but also to remind referral sources that one size never fits all and that solid measurement plans are a must.
