Well in my humble yet very personally respected opinion, behavioral therapies are nice, and they are enough for some people who i believe are willing to do anything to control their stutter, but for others they are just useful tool. And for others, myself included, it's not something we're high about. It just feels like compromising, which may very well be the wrong way to look at it, but if thats the case, our SLPs may need to help us find a better perspective that will serve us. But even beyond that, I think behavioral therapies are really limited in their approach. I'm currently trying a psych approach for my stutter, but many psychologists may be too uninformed when it comes to stuttering to really make it work. Then again, maybe i just havent found the right one. Anyway, avoidance reduction therapy was a breath of fresh air the first time i heard about it. I really think it could help a lot of people, but its not easy to do right. It takes real understanding to be able to apply the therapy effectively. If you want to know more, Vivian Sisskin is the #1 person I would go to.
