Executive function and childhood stuttering: Parent ratings and evidence from a behavioral task.

The study compared different children at one time point, so it cannot show that executive function differences cause stuttering or that they change as children grow older. The overall behavioral task result was null, and the difference appeared only in a later age-group analysis, so it should not be treated as the main finding. The behavioral task and parent questionnaire did not agree with each other, so the two measures may reflect different demands rather than one clear executive function profile. Children were required to have speech-language standard scores of 85 or higher on the tests they completed, so the results do not apply to children who stutter with co-occurring language or intellectual difficulties. Four children who stutter were already receiving speech-language services, and the paper does not say how this affected the results. Two children did not complete the hearing screening, so their hearing status was unknown. No intervention was tested, so the study does not show that targeting executive function improves fluency or everyday function.

The supplied metadata lists NIH extramural research support. The supplied text does not include an author conflict-of-interest statement.

Do not conclude that children who stutter have a general executive function problem or that treating executive function will improve fluency. The overall behavioral task showed no difference between groups, the parent-report finding was not linked to stuttering frequency, and no treatment was tested.
