Evidence-based treatment of stuttering: I. Definition and application

The philosophy guiding evidence-based treatment and its application to decision-making in stuttering treatment is described. Limitations to the use of evidence-based treatment principles to guide stuttering treatment, namely the lack of a substantial treatment research literature that can serve as the basis for meta-analyses and systematic reviews of effective treatment studies, are bemoaned. Guidelines are provided to aid clinicians in their own conduct of critical evaluations of treatment research. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to (1) describe the four steps that characterize evidence-based practice, (2) evaluate previous efforts to develop practice guidelines for stuttering, (3) assess the importance of an evidence-based approach to stuttering treatment, and (4) discuss the need for more research that will contribute to the evidence base.     

Evidence-based treatment of stuttering: III. Evidence-based practice in a clinical setting

At the heart of evidence-based practice in stuttering treatment are four issues: (1) the collection of data to inform treatment; (2) the long standing concern with maintenance of treatment gains; (3) the need to demonstrate accountability to clients, payers and our profession as service providers; and (4) the desire to advance theoretical knowledge. This article addresses the first three of these issues from a practical point of view, illustrating how data collection for stuttering treatment outcome research in a clinical setting is intimately blended with that required for clinical purposes and providing an example of a process of evaluating data for clinical and research purposes. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to (1) differentiate between treatment outcome and treatment efficacy research, (2) describe models for integrating data collection for treatment outcome and clinical purposes, and (3) utilize guidelines for treatment efficacy that are applicable to outcome research to evaluate data for use in treatment outcome studies and to design outcome studies.     

Evidence-based practice in stuttering: Some questions to consider

A recent forum in JFD (28/3, 2003) evaluated the status of evidence-based practice in fluency disorders, and offered recommendations for improvement. This article re-evaluates the level of support available for some popular approaches to stuttering therapy and questions the relative value placed on some types of programs endorsed by the forum. Evidence-based practice is discussed within the context of emerging concerns over its application to non-medical interventions and suggestions are made for grounding fluency interventions by reference to empirically supported principles of change. A popular, evidence-based intervention for stuttering in young children (the Lidcombe program) is evaluated within the suggested parameters. EDUCATIONAL OBJECTIVES: After reading this article, the reader will be able to: (1) evaluate the status of evidence-based practice in fluency disorders; (2) list concerns about the impact of narrow interpretation of EBP on research and practice in the field of fluency disorders and other non-medical domains; (3) articulate the role of theory and basic research in selecting among and evaluating therapy approach options.     

Evidence-based treatment of stuttering: II. Clinical significance of behavioral stuttering treatments

An evidence-based framework can be described as an empirically-driven, measurement-based, client-sensitive approach for selecting treatments. It is believed that using such a framework is more likely to result in a clinically significant outcome. For this paper, a clinically significant outcome was defined as a meaningful treatment change. It was suggested that there are at least three groups for whom a treatment's outcome is meaningful. These groups include clinicians/clinical researchers, the clients, and relevant others who have some interest in the outcome (e.g., parents of a child who stutters). The meaning and measurement of clinical significance was discussed for each of these three groups, based on research from the behavioral stuttering treatment literature. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to (1) broadly define a clinically significant outcome and identify some of the groups who are interested in such an outcome and (2) describe how clinical significance has been evaluated in stuttering treatment within an evidence-based framework.     

Multilingual children who stutter: clinical issues

Stuttering occurs across all languages and cultures. However, the impact of speaking more than one language on assessment and treatment of young children who stutter is not well documented. This paper discusses some of the challenges related to clinical issues pertaining to this population including (a) identifying stuttering in an unfamiliar language, (b) the influence of language proficiency, and (c) treatment of multilingual young children who stutter. The paper is written from the perspective of the author's experience treating multilingual children who stutter within the context of the linguistic and cultural diversity of Canada, notably in the French speaking Province of Quebec where many children grow up speaking two or more languages in everyday life. Clinical examples will be taken from the evidence-based literature as well as the author's clinical experience.Educational objectives: After reading this paper, the learner will be able to (1) summarize the literature regarding assessment and treatment of stuttering in young children speaking more than one language, (2) summarize some of the challenges related to this issue and (3) describe some of the findings associated with treatment of bilingual children who stutter and (4) be prepared to apply some of these suggestions in the treatment of bilingual children who stutter.     

Evidence-based treatment of stuttering: IV. Empowerment through evidence-based treatment practices

Assertion-based treatments for stuttering have historically been more popular than evidence-based treatments. In this paper it is argued that the use of evidence-based treatments for stuttering is professionally empowering for clinicians, but that the use of assertion-based treatments is a circular process that inhibits professional development. The arguments in favor of evidence-based treatment are elaborated under headings of "professional investment," "professional development and diversity," and "optimizing treatment efficacy." EDUCATIONAL OBJECTIVES: The reader will understand and be able (1) to describe the distinction between assertion-based and evidence-based treatment practices (2) to present a series of arguments that evidence-based treatment practices are professionally empowering.     

Contemporary issues with stuttering: The Fourth Croatia Stuttering Symposium

PurposeDuring the 2019 Fourth Croatia Clinical Symposium, speech-language pathologists (SLPs), scholars, and researchers from 29 countries discussed speech-language pathology and psychological practices for the management of early and persistent stuttering. This paper documents what those at the Symposium considered to be the key contemporary clinical issues for early and persistent stuttering.MethodsThe authors prepared a written record of the discussion of Symposium topics, taking care to ensure that the content of the Symposium was faithfully reproduced in written form.ResultsSeven contemporary issues for our field emerged from the Symposium.ConclusionEffective early intervention is fundamental to proper health care for the disorder. However, as yet, there is no consensus about the timing of early intervention and how it should be managed. Currently, clinical translation is a barrier to evidence-based practice with early stuttering, and proactive strategies were suggested for junior SLPs. Apprehension emerged among some discussants that treatment of early stuttering may cause anxiety. For persistent stuttering, assessment procedures were recommended, as were strategies for dealing with childhood bullying. There was agreement that SLPs are the ideal professionals to provide basic cognitive-behavior therapy for clients with persistent stuttering. Questions were raised about our discipline standards for basic professional preparation programs for stuttering management.     

Reprint of: technology and the evolution of clinical methods for stuttering

The World Wide Web (WWW) was 20 years old last year. Enormous amounts of information about stuttering are now available to anyone who can access the Internet. Compared to 20 years ago, people who stutter and their families can now make more informed choices about speech-language interventions, from a distance. Blogs and chat rooms provide opportunities for people who stutter to share their experiences from a distance and to support one another. New technologies are also being adopted into speech-language pathology practice and service delivery. Telehealth is an exciting development as it means that treatment can now be made available to many rural and remotely located people who previously did not have access to it. Possible future technological developments for speech-language pathology practice include Internet based treatments and the use of Virtual Reality. Having speech and CBT treatments for stuttering available on the Internet would greatly increase their accessibility. Second Life also has exciting possibilities for people who stutter.Educational objectives: The reader will (1) explain how people who stutter and their families can get information about stuttering from the World Wide Web, (2) discuss how new technologies have been applied in speech-language pathology practice, and (3) summarize the principles and practice of telehealth delivery of services for people who stutter and their families.     

The Lidcombe Program of early stuttering intervention for Malaysian families: Four case studies

PurposeThis study investigated the outcomes of implementing the Lidcombe Program, an evidence-based early intervention for stuttering, with four preschool children in Malaysia. Early stuttering intervention is currently underdeveloped in Malaysia, where stuttering treatment is often more assertion-based than evidence-based. Therefore, introducing an evidence-based early stuttering intervention is an important milestone for Malaysian preschoolers who stutter.MethodThe participants ranged from 3 years 3 months to 4 years 9 months at the start of the study. Beyond-clinic speech samples were obtained at 1 month and 1 week pretreatment and immediately post-Stage 1, and at 1 month, 3 months, 6 months and 12 months post-Stage 1.ResultsTwo participants, who were bilingual, achieved near-zero levels of stuttering at 12 months posttreatment. Near zero levels of stuttering were also present in their untreated languages. One participant withdrew due to reasons not connected with the research or treatment. The remaining participant, who presented with severe stuttering, completed Stage 1 but had some relapse in Stage 2 and demonstrated mild stuttering 12 months post-Stage 1.ConclusionsThe outcomes were achieved without the need to significantly adapt Lidcombe Program procedures to Malaysian culture. Further research to continue evaluation of the Lidcombe Program with Malaysian families and to estimate proportion of those who will respond is warranted.     

The Virtues of Evidence

Evidence-based medicine has been defined as the conscientious and judicious use of current best evidence in making clinical decisions. This paper will attempt to explicate the terms "conscientious" and "judicious" within the evidence-based medicine definition. It will be argued that "conscientious" and "judicious" represent virtue terms derived from virtue ethics and virtue epistemology. The identification of explicit virtue components in the definition and therefore conception of evidence-based medicine presents an important starting point in the connection between virtue theories and medicine itself. In addition, a unification of virtue theories and evidence-based medicine will illustrate the need for future research in order to combine the fields of virtue-based approaches and clinical practice.     

Technology and the evolution of clinical methods for stuttering

The World Wide Web (WWW) was 20 years old last year. Enormous amounts of information about stuttering are now available to anyone who can access the Internet. Compared to 20 years ago, people who stutter and their families can now make more informed choices about speech-language interventions, from a distance. Blogs and chat rooms provide opportunities for people who stutter to share their experiences from a distance and to support one another. New technologies are also being adopted into speech-language pathology practice and service delivery. Telehealth is an exciting development as it means that treatment can now be made available to many rural and remotely located people who previously did not have access to it. Possible future technological developments for speech-language pathology practice include Internet based treatments and the use of Virtual Reality. Having speech and CBT treatments for stuttering available on the Internet would greatly increase their accessibility. Second Life also has exciting possibilities for people who stutter.Educational objectives: The reader will (1) explain how people who stutter and their families can get information about stuttering from the World Wide Web, (2) discuss how new technologies have been applied in speech-language pathology practice, and (3) summarize the principles and practice of telehealth delivery of services for people who stutter and their families.     

In pursuit of fluency

It is suggested that fluent speech is a behavior that is relatively easy for the clinician to obtain from the majority of stuttering clients. Specific moments of stuttering, on the other hand, are often much more difficult to elicit. The rationale for this opinion and some therapeutic implications are discussed. Two areas of future research are advocated: (1) investigation of the conditions that appear to aid the clinician in eliciting moments of stuttering and (2) exploration into a phenomena that appears to be a basic component of the moment of stuttering-“loss of control.”     

Subtyping stuttering I: a review

A reliable and practical subtype system of stuttering should enhance all related scientific work concerned with this disorder. Although a fair number of classification systems have been offered, to date, none has received wide recognition or has been routinely applied in research or clinical spheres. Whereas progress has been made in understanding and treating the disorder, for the most part stuttering continues to be viewed and addressed as a unitary problem. The objectives of the current article are to (a) highlight the motivation for identifying sub-types of stuttering, (b) outline the issues involved in researching subtypes, and (c) address the question of whether or not subtyping is plausible for this disorder. Toward these ends, a broad-based review of past concepts regarding subtypes of stuttering and stutterers is presented according to seven categories that reflect the various authors' conceptual or experimental approaches. Selected studies for each category are also presented to illustrate the research problems and challenges. It is concluded that islands of progress can be identified in subtype research, particularly in studies of children. It is recommended that future studies include multiple factors or domains in the data collection process, especially with young children during the formative years of the disorder, when substantial overlap in the development of several speech/language domains occurs. EDUCATIONAL OBJECTIVES: (a) Readers will be able to describe the theory and research concerning the numerous attempts to subtype stuttering, particularly during the past 50 years; (b) Readers will be able to explain the general issues that need to be resolved in order to identify subtypes as well as current and future research strategies aimed at achieving these goals.     

Assessment of stuttering in a familiar versus an unfamiliar language

The present study investigated how well individuals knowledgeable about stuttering are able to make disfluency judgments in clients who speak another language than their own. Fourteen native speakers of Brazilian Portuguese identified and judged stuttering in Dutch speakers and in Portuguese speakers. Fourteen native speakers of Dutch identified and judged stuttering in Brazilian Portuguese speakers and in Dutch speakers. It was found that judges can make similar level of judgment in a native and a foreign language, and that native and foreign judges can make similar level of judgment irrespective of native/foreign differences. It was also found, however, that the Dutch judges performed significantly better in identifying native stutterers than foreign stutterers. And for the identification of nonstutterers, both panels performed better in their native language than in the foreign language, and in their native language they both performed better than the other panel. Both the Brazilian Portuguese and the Dutch speaking panel were generally also less confident, and found identification of stuttering more difficult in the foreign language than in the native language. In addition, when asked for the characteristics that helped them identify stutterers, they provided more detail in the native language than in the foreign language. Also a number of differences were found between the two panels which may be due to differences in training or cultural background. The implications of the findings for clinical practice and for future research in this area are discussed. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) describe how language influences the identification of a speech disorder such as stuttering, and (2) list, and (3) define behaviors that help to identify stuttering in a foreign language.     

Mindfulness training in stuttering therapy: a tutorial for speech-language pathologists

The use of mindfulness training for increasing psychological well-being in a variety of clinical and nonclinical populations has exploded over the last decade. In the area of stuttering, it has been widely recognized that effective long-term management often necessitates treatment of cognitive and affective dimensions of the disorder in addition to behavioral components. Yet, mindfulness based strategies and their possible usefulness in stuttering management have not been described in detail in the literature. This article seeks to engage professionals who treat stuttering in a conversation about the possible usefulness of incorporating mindfulness training into stuttering management. A review of the literature reveals that there is a substantial overlap between what is required for effective stuttering management and the benefits provided by mindfulness practices. Mindfulness practice results in decreased avoidance, increased emotional regulation, and acceptance in addition to improved sensory-perceptual processing and attentional regulation skills. These skills are important for successful long-term stuttering management on both psychosocial and sensory-motor levels. It is concluded that the integration of mindfulness training and stuttering treatment appears practical and worthy of exploration. Mindfulness strategies adapted for people who stutter may help in the management of cognitive, affective, and behavioral challenges associated with stuttering.Educational objectives: Readers should be able to: (1) describe what mindfulness is and how it is cultivated; (2) identify the benefits that can be produced from mindfulness practice; (3) summarize how the benefits of mindfulness practice parallel what is often required for effective long-term stuttering management; and (4) identify specific mindfulness techniques that can be taught in stuttering therapy and explain their rationale.     

Family therapy and the politics of evidence

This article situates family therapy in the politics of evidence-based practice. While there is a wealth of outcome research showing that family therapy works, it remains on the margin of mainstream therapy and mental health practice. Until recently it has been difficult to satisfy 'gold standards' of randomized control research which require manualization and controlled replication by independent investigators. This is because systemic family therapy is language-based, client-directed and focused on relational process rather than step-by-step operational techniques.
As a consequence family therapy is an empirically supported treatment unable to join the evidence-based club. The politics here concerns what is 'evidence', who defines it and the limitations of a scientist-practitioner model. Therapy is art and science and its research needs to be grounded in real-life clinical practice. Common factors such as personal hope and resourcefulness and the therapeutic relationship contribute more to change than technique or model.
While arguing for a wider definition of science and evidence it is politic to seek evidence-based status for family therapy. Family therapy is a best practice approach for all therapists where systemic wisdom helps to decide what to do with whom when . A systemic-practitioner model is informed by quantitative and qualitative research and holds modern and postmodern perspectives in tension, a stance I call paramodern . Family therapy is both scientific and systemic; it is a science of context, narrative and relationship.     

Cognitive-behavioral treatment of childhood obsessive-compulsive disorder in community-based clinical practice: clinical significance and benchmarking against efficacy

Objective

To evaluate the feasibility and outcomes of evidence-based (EB) manualized, cognitive-behavioral treatment (CBT) for childhood obsessive-compulsive disorder (OCD), when delivered in an outpatient community-based specialist clinic.

Method

This study, conducted in an outpatient private clinic in South-East Queensland Australia, involved thirty-three children and adolescents with OCD. Children were assessed at pre- and post-treatment, by means of diagnostic interviews, symptom severity interviews, and self-report. Treatment involved 12 sessions CBT delivered either individually or in small groups and included parental involvement.

Results

Manualized CBT could be transported to the community setting effectively, with 63% of the current sample responding positively, based on post-treatment diagnosis. Significant change was evident across a wide-range of outcomes; including, diagnostic severity, symptom severity, child reported depression and anxiety, and both child and parent reported OCD functional impairment.

Conclusions

This study provides evidence for the transportability of manualized CBT in clinical community practice for pediatric OCD. The next important step is larger community based dissemination and effectiveness studies to advance both research and clinical practice outcomes.     

The "Iowa Way" revisited

This paper attempts to bridge the gap between past and present stuttering therapy approaches. Specifically, the ideas and methods of Wendell Johnson and Dean Williams are compared to current approaches used in treating mental illness and communication disorders in which there is an emphasis on focusing on what is “right” with the individual and spending less time focusing on the “disorder”. There is particular emphasis on tying Johnson's and Williams’ overall philosophy to modern psychological approaches rooted in “Positive Psychology”, to highlight how these early ideas in stuttering therapy may help us to discover the common factors that underlie the success of several different stuttering therapy approaches, independent of the specific techniques employed. It is proposed that future research on clinical efficacy in stuttering should use focused hypotheses techniques to investigate common factors that make therapy effective across individuals and therapy approaches.Educational objectives: The reader will be able to: (1) summarize the basic philosophy of the “Iowa” approach to stuttering as laid out by Wendell Johnson and Dean Williams; (2) describe current therapeutic techniques that incorporate “positive psychology”; (3) discuss possible common factors that influence therapy outcome that are independent of the therapeutic technique employed.     

The local clinical scientist, evidence-based practice, and personality assessment

The local clinical scientist model was devised for clinical practitioners including those engaged in personality assessment. It emphasizes the importance of local data, the consideration of each clinical encounter as a mini-research project, and the incorporation of existing research data where relevant. It is consistent with, but goes beyond, evidence-based practice. There is a need to guard against the operation of cognitive heuristics for the model to be applied effectively.
