Comment on stuttering review
In the June 25, 2011 edition of the British Medical Journal O'Brian
and Onslow2 provide an overview of clinical management of developmental
stuttering in children and adults. Included in that review is the
following statement: "An Australian cohort study (n=1619) of children
recruited at 8 months of age found that 8.5% had begun to stutter a (sic)
36 months of age, and 12.2% by 48 months.1"
Given the overwhelming contrary evidence from numerous surveys of
stuttering in children3 showing that an 8.5% prevalence in 3 year old
children is an extraordinarily high figure, then it becomes even more
extraordinary to claim a prevalence of 12.2% in 4 year old children. That
claim is made even more suspect because the supplied reference for the
finding1 does not contain any evidence justifying that claim. The Reilly
et al. (2009, p. 275) paper states clearly "This report includes onset
only up to 3 years." Neither the Reilly et al. report nor O'Brian and
Onslow's review contain any data on 4 year old children. This misleading
claim requires explanation.
