Behavior analysts' perceptions of the population specificity or comprehensiveness of autism treatments
Most BCBAs say ABA works for everyone, yet many still back non-science fixes—time to pair our universal confidence with individualized, assessment-driven plans.
01Research in Context
What this study did
Campbell et al. (2021) sent an online survey to certified behavior analysts.
They asked whether ABA works for everyone with autism or only for some groups.
The survey also asked about non-science-based treatments like special diets or sensory rooms.
What they found
Three out of four BCBAs said ABA is effective for all people with autism.
Yet many of those same analysts also said non-evidence treatments can help certain kids.
The results show a split between strong faith in ABA and lingering openness to fads.
How this fits with other research
Chung et al. (2024) agree ABA is top-tier, but they stress picking the style that fits each child.
Campbell (2003) and Heyvaert et al. (2014) prove ABA cuts problem behavior best when a functional analysis is done first.
Fleury et al. (2019) show parents trust treatments more when you say “evidence-based” out loud.
Together these papers hint the field already knows how to tailor ABA; the survey shows many BCBAs just don’t do it.
Why it matters
If you treat every child the same, you risk slow progress and burnt-out staff.
Use the meta-analyses as your guide: assess first, then match the procedure to the function.
When you explain this plan to families, call it “evidence-based” and share the data.
You’ll keep the science in behavior analysis and stop quietly endorsing non-science fads.

03Original abstract
AbstractThe basic philosophy of radical behaviorism provides foundations for behavioral intervention applications in applied behavior analysis (ABA) across a variety of populations and human behaviors. However, as ABA increases in popularity for people with autism, many people perceive that ABA resembles other non‐research‐supported interventions which market themselves almost exclusively for autism. This study evaluated the extent to which behavior analysts perceived scientifically supported treatments (e.g., ABA) and non‐scientifically supported treatments as population‐specific or as comprehensively applicable across populations. Behavior analysts (N = 876) completed an online survey which indicated that approximately 3/4 of behavior analysts reported ABA as comprehensively effective for all people. Treatments without scientific support also were ranked more often or as effective as ABA for specific populations (i.e., intellectual and developmental disabilities, autism, severe behavior problems, adults, and children). Results indicated a continuing need to emphasize the education and requirements of radical behaviorism as the scientific foundations of ABA.
