CBT is for specific phobias and anxiety disorders, and for that, it works well (OCD here), but these things are based on an erroneous cognitive thought process, but unlike ASDs, which aren't based on specific thoughts, rather innate differences of the mind. One individual there kept on assuring me that sensory problems were in fact anxiety related, and no matter how much I said that, 'hey, it's actually the overstimulation that's making me uncomfortable, which in turn creates the anxiety I feel,' "she" wouldn't listen. Personally, I saw this as them just...firing over that mountain blindly, because they had nothing else. Yeah, I see that now, often (medication); however, some children either have to stay at home or be medicated to attend ASD schools. It's a rock and a hard place here with these children.
CBT works well for anxiety disorders, as I said.
