Although I have a really healthy ego, so my negative self view came from the experience of being a freak in society who became embarrassed about his speech. So learning to accept myself largely fixed the problem. However, for people who have much deeper psychological issues, such as from parental abuse, or other things, I don't think my solution would work. I think people with deep seated pain and issues that predate the stuttering would need some kind of psycho or cognitive therapy to work on themselves. And by the way, I've done a bit of psycho and cognitive therapy when I was having a bad relationship and it really helped me to deal with problematic people in my life. Once I learned how certain types of personalities react to certain things, I learned not to take things so personally. But therapy only works if you are really willing to take a deep, hard, critical look at yourself, and be honest with yourself. You can't be super defensive and make big gains in therapy.
