Dee-dee,
I honestly have zero experience with ABA and therefore, probably shouldn't have included it. I added it in the list b/c of info I got from an OT friend of mine. Her son does ABA for ADHD, but I don't know much about it. From the little she shared with me about it, it sounds more like she is describing behavior modification techniques. She did say that the methods are adapted to fit ADHD rather than autism spectrum disorders, but that's all I know. I did try to search online for some info on ABA for ADHD, but I didn't find much. This is what I found, and it's certainly not any kind of substantial info or proof that it works. In fact the yahoo answers post has a reply from a doctor who says it's not an appropriate therapy for ADHD (I think; I just glanced at it.) Sorry!
