A Longitudinal Study of Stuttering in Children

A Preliminary Report

It has come to our attention that minor errors occurred in Table 3 on p. 759 of the Yairi and Ambrose article, "A Longitudinal Study of Stuttering in Children: A Preliminary Report," which appeared in the August 1992 issue (Vol. 35, pp. 755–760). A revised version of the table appears below that includes both the original values and the corrected values (in boldface). As can be seen, the differences are indeed minor. The changes do not affect the reported patterns or level of statistical significance. In the untreated group, 7 or 78% recovered by 24 months post-onset and 1 additional subject recovered later, making a total recovery rate of 89%, with 11% persistent. In the treated group, 11 or 61% recovered by 24 months post-onset and an additional 5 recovered later, again totalling 89% recovery and 11% persistent. These data do not in any way indicate that treatment is not beneficial nor that it has no effect but simply that success rates for treated individuals must take spontaneous recovery into account. We regret the error.
