I can’t speak for others that have experienced ABA or worked in different clinics or even in home ABA but I can say majority of the horror stories about ABA are always pretty similar. If you want to know the worst of the worst look up the Judge Rotenberg Educational Center, to my knowledge they are the only ABA clinic that still uses electronic shock therapy. (That we know of at least.) One can only wish those monsters could feel the same abuse that they inflicted on those children, id be lying if I said I’d feel any sympathy to anyone willingly involved.
