I’m sorry that this was your experience, truly. I speak as someone who has stuttered for most part of his life with a background in psychology. I must say most psychology training does not cover every specific condition unless they are very prevalent in the population (e.g. substance abuse etc). However, the general models you learn in training allows you to have a good understanding of the mechanisms of the mind, brain, and body interaction. I think any good and dedicated psychologist can invest the time to work out the underlying psychological mechanism of stuttering. But you also make a valid point about having the time and maybe even the interest for some or most. Overall I must also say that I’ve come across enough feedback from people who felt like tackling the underlying anxiety and social difficulties helped a lot. So I’d say maybe the problem was the psychologists or their lack of time/dedication to figure it out? Glad to hear you found someone willing to work collaboratively with a speech therapist!
