The Nature and Extent of Component Analyses for Improving or Mitigating Behavior: A Systematic Review.
Half of ABA packages can be slimmed down—run a quick component test before you treat every part as sacred.
01Research in Context
What this study did
Moya et al. (2022) hunted for every ABA paper that pulled apart a treatment package.
They found 21 studies that tested if you can drop pieces and still keep the good results.
Kids and adults with autism, ADHD, or ID filled the participant lists.
Each study compared the full package against smaller versions to spot the must-have part.
What they found
Only ten of the 21 papers found one golden piece that did all the work.
Two studies said every part was needed; the rest gave muddy or mixed answers.
In short, you have a fifty-fifty shot that your fancy package is over-stuffed.
How this fits with other research
Oliver et al. (2002) is inside the review. Their helmet study shows safety gear can hide the true reason for self-hitting. The review counts this as a case where one piece (no helmet) changes everything.
Frank-Crawford et al. (2018) is also in the pool. They saw that high-ranked toys failed when kids had to work hard. The review labels this another “single critical piece” win, matching the ten clear-cut cases.
Wouters et al. (2017) used the same review method but on fitness tests, not ABA parts. Both papers end with the same warning: narrow evidence bases limit wide use.
Why it matters
Before you run the full social story, token board, and DRA combo, test each slice.
Pick the cheapest or fastest piece first and run a mini-experiment.
If behavior holds, you just saved time, money, and client fatigue.
If it crashes, you have quick proof the whole bundle is worth it.

03Original abstract
A component analysis is an approach where two or more independent variables are evaluated as a package and independently. The approach is used to assess and identify which component of a treatment package is the most effective. The purpose of this review is to document the application of component analyses to improve or mitigate non-academic behaviors with individuals with disabilities. We identified 21 research articles that used a component analysis to evaluate treatment packages with students who were identified as having or at-risk for a disability in classroom and/or alternative settings. Results from reviewing 21 articles (22 cases) indicate that 11 intervention packages had a single component that was critical for successful behavior change. Two articles suggested the entire intervention package was necessary while nine articles did not report a critical component or had variable results pertaining to critical components. The benefits and drawbacks of using component analyses for single case research are discussed. Implications for future research are also presented.
