BackgroundThe growing range of available treatment options for people who
stutter presents a challenge for clinicians, service managers and commissioners,
who need to have access to the best available treatment evidence to guide them in
providing the most appropriate interventions. While a number of reviews of
interventions for specific populations or a specific type of intervention have
been carried out, a broad‐based systematic review across all forms of intervention
for adults and children was needed to provide evidence to underpin future
guidelines, inform the implementation of effective treatments and identify future
research priorities.AimsTo identify and synthesize the published research evidence on the
clinical effectiveness of the broad range of non‐pharmacological interventions for
the management of developmental stuttering.Methods & ProceduresA systematic review of the literature reporting interventions for
developmental stuttering was carried out between August 2013 and April 2014.
Searches were not limited by language or location, but were restricted by date to
studies published from 1990 onwards. Methods for the identification of relevant
studies included electronic database searching, reference list checking, citation
searching and hand searching of key journals. Appraisal of study quality was
performed using a tool based on established criteria for considering risk of bias.
Due to heterogeneity in intervention content and outcomes, a narrative synthesis
was completed.Main ContributionThe review included all available types of intervention and found
that most may be of benefit to at least some people who stutter. There was
evidence, however, of considerable individual variation in response to these
interventions. The review indicated that effects could be maintained following all
types of interventions (although this was weakest with regard to feedback and
technology interventions).ConclusionsThis review highlights a need for greater consensus with regard to
the key outcomes used to evaluate stuttering interventions, and also a need for
enhanced understanding of the process whereby interventions effect change. Further
analysis of the variation in effectiveness for different individuals or groups is
needed in order to identify who may benefit most from which intervention.
