A three-arm randomized controlled trial of Lidcombe Program and Westmead Program early stuttering interventions.

PURPOSE: To compare two experimental Westmead Program treatments with a control Lidcombe Program treatment for early stuttering. METHOD: The design was a three-arm randomized controlled trial with blinded outcome assessments 9 months post-randomization. Participants were 91 pre-school children. RESULTS: There was no evidence of difference in percentage syllables stuttered at 9 months among groups. Dropout rates were substantive and may have been connected with novel aspects of the trial design: the use of community clinicians, no exclusion criteria, and randomization of children younger than 3 years of age. CONCLUSION: The substantive dropout rate for all three arms in this trial means that any conclusions about the 9-month stuttering outcomes must be regarded as tentative. However, continued development of the Westmead Program is warranted, and we are currently constructing an internet version.

A phase II trial of the Westmead Program: syllable-timed speech treatment for pre-school children who stutter.

This report presents a Phase II clinical trial of a syllable-timed speech treatment for early stuttering known as The Westmead Program. Of 17 children recruited, eight children aged between 3-4.5 years (mean 3 years 8 months) completed the treatment. The primary outcome measure was percentage syllables stuttered (%SS) measured from independent, blinded speech assessments of beyond-clinic audio recordings. Secondary outcomes were measures of treatment time, speech quality, and parent severity ratings. Dropouts occurred, but at a similar rate to other clinical trials of this nature. For the eight children who completed the treatment, mean pre-treatment stuttering was 6.0%SS and at 12-months post-Stage 2 entry stuttering had decreased to 0.2%SS, representing a mean stuttering reduction of 96%. A large effect size was obtained with a mean of 8.0 clinical hours required for these children to reach Stage 2. Independent listeners judged the everyday speech of all children to be not unnatural in any way. Stuttering reductions were attained with clinical efficiency and simplicity compared to other early stuttering interventions. Further clinical trials development of the treatment is warranted.

Using syllable-timed speech to treat preschool children who stutter: a multiple baseline experiment.

UNLABELLED: This report presents the results of an experimental investigation of the effects of a syllable-timed speech treatment on three stuttering preschool children. Syllable-timed speech involves speaking with minimal differentiation in linguistic stress across syllables. Three children were studied in a multiple baseline across participants design, with percent syllables stuttered (%SS) as the dependent variable. In the week following the initial clinic visit, each child decreased their beyond-clinic stuttering by 40%, 49% and 32%, respectively. These reductions are only evident in the time series after the introduction of the syllable-timed speech treatment procedure. Participants required a mean of six clinic visits, of approximately 30-60 min in duration, to reach and sustain a beyond-clinic %SS below 1.0. The results suggest that clinical trials of the treatment are warranted. EDUCATIONAL OBJECTIVES: The reader will be able to summarize, discuss and evaluate: (1) The nature, impact and treatment options available for early stuttering. (2) The syllable-timed speech treatment protocol administered. (3) The advantages of syllable-timed speech treatment for early stuttering. (4) The questions that further research needs to answer about the syllable-timed speech treatment.
