ABA in simple words
What applied behavior analysis is. What it can do, what it should not. Without jargon, with references to CDC, NICE, AAP.
I will say right away. ABA is not some separate method, not a course, not a "system of exercises." It is a scientific approach to how people learn, and how behavior is influenced by what happens before and after it. Large organizations like CDC, AAP, and NICE describe this approach very similarly.
Behavior is a message
What often seems to adults like "bad behavior" (screaming, aggression, running away) is usually a way to say something. "It is hard for me." "I do not understand." "It hurts." "It is too loud here." "I want a break." "I cannot wait." "Help."
NICE directly requires that when assessing behavior that causes concern, the following be checked:
* communication difficulties
* physical condition (pain, gastrointestinal problems)
* sensory conditions (noise, light, touch)
* changes in routine
* accidental reinforcement of behavior by adults themselves
That is, before "unlearning," a modern specialist tries to understand why the child does this.
What ABA can really help do
* functional communication (ask for a break, "it hurts," "help")
* self-care (toilet, dressing, hygiene, food)
* safety (stopping at the road, not running away)
* transitions between activities
* waiting with support
* reducing dangerous behavior through alternative skills
What ABA should not do
* promise to "cure autism." This does not exist
* make the child "normal" or "invisible"
* forbid safe stimming only because it "looks strange"
* force eye contact when the child does not want it
* use shame, fear, shouting, pain, physical coercion
This is not my opinion but an ethical consensus. WHO emphasizes rights and quality of life. NICE places emphasis on sensory adaptations and the child's preferences. BACB (the professional association of behavior analysts) requires respect for dignity and minimization of harm.
About "hours" and "volume"
It used to be thought that the more hours of ABA, the better. More recent data does not support this simply. A 2018 Cochrane review found only weak evidence of benefit from intensive programs. A 2024 JAMA Pediatrics meta-analysis did not find a reliable connection between volume and progress in small children.
So the right question for the specialist is not "how many hours will you give" but "what functional goals do you set," "how do you measure them," "how will you understand that this is really helping the child."
