Self-contained ear-level devices delivering altered auditory feedback (AAF) for the application with those who stutter have only been recently developed. The paper examines the first therapeutic application of self-contained ear-level devices in three experiments. The effect of the device on the proportion of stuttered syllables and speech…

Background: Bloodstein reviewed hundreds of studies that investigated the efficacy of therapeutic protocols for ameliorating the stuttering syndrome. Surprisingly, almost all were effective in significantly reducing overtly perceptible behaviours such as repetitions and prolongations of speech sounds. These results seem highly improbable…

Background: There will always be a place for stuttering treatments designed to eliminate or reduce stuttered speech. When those treatments are required, direct speech measures of treatment process and outcome are needed in clinical practice. Aims: Based on the contents of published clinical trials of such treatments, three "core" measures of…

Background: This paper is intended to contribute to the current debate in relation to persistent stuttering and evidence-based clinical practice. Aims: The paper will describe the authors' intervention framework for persistent stuttering, which is guided by evidence from the fields of stuttering and clinical psychology. It supports the opinion…

Background: Speech and language therapists treating children who stutter appear to be assigned a difficult task. Natural spontaneous remission accounts for approximately 60-80% of all children recovering from stuttering. Despite our best efforts, no protocol has ever shown its effectiveness separate from natural recovery rates (i.e. 60-80%).…

Background: In recent years, the importance of a multimodal approach to the assessment of the person who stutters (PWS) has become increasingly recognized. The Behavior Assessment Battery (BAB), which is a normed test procedure developed by G. Brutten, makes it possible to assess the multidimensional facets of this disorder. The emotional and…

Background: The development of evidence-based practice, which is increasingly popular in stuttering treatment, is closely linked to the development of outcome measures. Aims: Two approaches to the development of stuttering treatment outcome measures are outlined. The first is the deductive, top-down approach, where the development of specific…

Background: Similar positive results (e.g. immediate decreases in stuttering frequency and a 60-80% recovery rate from stuttering) have been reported for numerous therapeutic protocols for treating childhood stuttering, many of which have been diametrically opposite in their orientations and implementations. For example, Johnson advocated indirect…

Background: Data have accumulated to show that the Lidcombe Program of early stuttering intervention is a safe treatment with positive outcomes for preschoolers who stutter, and a randomized controlled trial is under way at the time of writing. Program components have not been investigated experimentally so the functionality of each component is…

Background: It has been suggested that one way to increase speech pathologists' confidence in working with people who stutter is to provide them with relevant and stimulating clinical experiences during their professional preparation. This paper describes a treatment programme for adults who stutter that is conducted by speech pathology students,…

Background: Those engaged in research might argue that we are involved in a process of explaining the world to others and to ourselves. The way in which we go about that process differs. The kind of questions we are concerned about answering will determine the approach we use, the information we gather and how we analyse the data. Some research…

Background: The paper reports on a laboratory investigation of the effects of self-modelling on stuttering rate in adolescents and adults. Self-modelling refers to a therapeutic or training method, usually involving videotape, that uses exposure to oneself performing selected error-free behaviours as the conduit for promoting behaviour change.…

Background: To the person who stutters, there are other experiences than the somatic ones of stuttered speech. These are experiences of cognition and affect: in other words, experiences of thought and emotion. For several reasons, it is quite difficult to determine and recommend core measures of cognition and affect for clinicians to consider…

"Background": Clinical trials have shown that behavioural treatments based on variants of prolonged-speech (PS) are best practice for reducing the stuttering rate in adults. However, while stuttering is significantly reduced or eliminated for most adults in the short-term with such treatment, relapse in the longer-term is common. Consequently,…
