Project Description

This project consisted of 9 children who stutter, 6 boys and 3 girls, between the ages of 2;0 and 4;11, who were followed for 10 months each. The duration of the data collection for the study was from 2003-2005. Children received vocabulary and overall language testing in the first month of the study, and language samples were obtained each month, for a total of 10 samples per child.

The language sample protocol consisted of the child and an examiner (trained graduate research assistant) conversing during interactive play. Occasionally, a parent or sibling was involved in the interaction, as well. A standard set of interactive toys and books was used, from which the child could select at the beginning of each session.

Although 11 children completed the study, two of the children produced less than 3% stuttered syllables for all of their 10 samples and therefore are not included in the dataset. These participants are also excluded from the articles referenced above.

The datasheet provides demographic information for each participant and language test scores. Stuttering severity was estimated in the first session using the Stuttering Severity Instrument, 3rd Edition (Riley, 1994). However, for most children, stuttering fluctuated throughout the ten months of the study.
