Here some important quotes:
The Wellcome Trust team says a specific speech test accurately predicts whose stutter will persist into their teens. The researchers, based at University College London, used a test developed in the US called SSI-3 (stuttering severity instrument). They found that the SSI-3 test was a reliable indicator of who would still have a stutter and who would recover - while other indicators such as family history, which have been used, were less so.I am not sure exactly what the hype is about, but it seems to be saying that the more severe you stutter as a child the less likely you recover? That sounds to me obviously true on average. That's also the factor I found in my outcome study that correlates with positive outcome: the less you stutter before treatment, the more likely you are fluent afterwards! I have to read the paper, but I am skeptical.
The most interesting comment is that "researchers also found so-called "whole word repetition" was not a reliable indicator of persistent stutter". I vaguely remember that being a prediction by the EXPLAN theory pushed by Pete Howell. But I could be wrong.
I am also not impressed by Mr Lieckfeldt's BBC comment:
"At five, there is still a window of opportunity to help those with a stammer."
And afterwards, no opportunity to help those with a stammer? ;-)
"If we intervene early enough, there is a really high success rate of normal, fluent speaking, whereas for six- to eight-year-olds, the recovery rate drops like a stone."
OBVIOUSLY, due to the natural recovery rate! Those that would recover, recovered already!
