ABA in One Week?

This CNN article gives a pretty decent basic explanation of applied behavioral analysis, which is the most widely used autism intervention methodology. Based on my personal experience, I really have to wonder whether this ABA therapist was able to turn around this girl's behavior in a one week intervention. I vividly remember the day it took five adults to restrain both of my boys during in-home training, and A. still managed to bite a chunk of flesh from the psychiatrist. Moreover, most experts I've read speak in terms of years.
