To assess the immediate and long‐term effects of non‐pharmacological interventions for stuttering on speech outcomes, communication attitudes, quality of life and potential adverse effects in children aged six years and younger.
To describe the relationship between intervention effects and participant characteristics (i.e. child age, IQ, severity, sex and time since stuttering onset) at pretest.
Data collection and analysis
All four studies reported the outcome of stuttering frequency. One study also reported on speech efficiency, defined as articulation rate. No studies reported the other predetermined outcomes of this review, namely stuttering severity; communication attitudes; emotional, cognitive or psychosocial domains; or adverse effects.
The Lidcombe Program resulted in a lower stuttering frequency percentage syllables stuttered (% SS) than a wait‐list control group at post‐test, 12 weeks, 16 weeks and nine months postrandomization (mean difference (MD) −2.16, 95% confidence interval (CI) −3.48 to −0.84, 4 studies, 151 participants; P = 0.001; very low‐certainty evidence).
However, as the Lidcombe Program is designed to take one to two years to complete, none of the participants in these studies had finished the complete intervention programme at any of the data collection points.
We assessed stuttering frequency to have a high risk of overall bias due to high risk of bias in at least one domain within three of four included studies, and to have some concern of overall bias in the fourth, due to some concern in at least one domain.
We found moderate‐certainty evidence from one study showing that the Lidcombe Program may increase speech efficiency in young children.
Only one study reported outcomes at long‐term follow‐up. The long‐term effect of intervention could not be summarized, as the results for most of the children in the control group were missing. However, a within‐group comparison was performed between the mean % SS at randomization and the mean % SS at the time of extended follow‐up, and showed a significant reduction in frequency of stuttering.
