INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2019; 54:927-939. [PMID: 31364252 DOI: 10.1111/1460-6984.12496] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Revised: 06/25/2019] [Accepted: 06/30/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND iGlebe is a fully automated internet treatment program for adults who stutter that has been shown, in some cases, to reduce anxiety and effectively manage social anxiety disorder for many participants. No such automated internet treatment program exists for adolescents who stutter. AIMS The present paper reports a Phase I trial of an adolescent version of the adult program: iBroadway. METHODS & PROCEDURES Participants were 29 adolescents in the age range 12-17 years who were seeking cognitive-behaviour therapy (CBT) for anxiety associated with stuttering. The design was a non-randomized Phase I trial with outcome assessments at pre-treatment and immediately post-treatment after 5 months of access to the program. No contact by a clinical psychologist occurred during participant use of the program. Outcomes were a range of psychological, quality-of-life and stuttering severity measures. OUTCOMES & RESULTS The compliance rate for the seven iBroadway modules over 5 months was extremely favourable for internet CBT, at 52.4%. There was evidence of treatment effects for (1) the number of DSM-IV mental health diagnoses with the Diagnostic Interview Schedule for Children; (2) the Unhelpful Thoughts and Beliefs About Stuttering scale; (3) the Subjective Units of Distress Scale; and (4) parent-reported speech satisfaction. CONCLUSIONS & IMPLICATIONS Further development of iBroadway, the adolescent version of iGlebe, with Phase II trialling is warranted.

Abstract
Childhood-onset fluency disorder, the most common form of stuttering, is a neurologic disability resulting from an underlying brain abnormality that causes disfluent speech. Stuttering can lead to significant secondary effects, including negative self-perception and negative perception by others, anxiety, and occasionally depression. Childhood-onset fluency disorder affects 5% to 10% of preschoolers. Early identification of stuttering is important so that therapy can begin while compensatory changes to the brain can still occur and to minimize the chances of the patient developing social anxiety, impaired social skills, maladaptive compensatory behaviors, and negative attitudes toward communication. However, stuttering may be persistent, even with early intervention, and affects about 1% of adults. In patients with persistent stuttering, speech therapy focuses on developing effective compensatory techniques and eliminating ineffective secondary behaviors. The role of family physicians includes facilitating early identification of children who stutter, arranging appropriate speech therapy, and providing support and therapy for patients experiencing psychosocial effects from stuttering. Finally, physicians can serve as advocates by making the clinic setting more comfortable for people who stutter and by educating teachers, coaches, employers, and others in the patient's life about the etiology of stuttering and the specific challenges patients face.

Eichorn N, Pirutinsky S, Marton K. Effects of different attention tasks on concurrent speech in adults who stutter and fluent controls. JOURNAL OF FLUENCY DISORDERS 2019; 61:105714. [PMID: 31472297 DOI: 10.1016/j.jfludis.2019.105714] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 08/15/2019] [Accepted: 08/20/2019] [Indexed: 06/10/2023]
Abstract
PURPOSE Motor theories indicate that focusing attention on well-practiced movements interferes with skilled performance; however, specific forms of attention (alerting vs. orienting vs. executive control) associated with this effect are not well understood. The present study explored this question in relation to stuttering, and examined whether dual task conditions that engaged sustained attention or working memory (WM) affected speech fluency in different ways. We also considered whether fluency changes were associated with changes in speech rate and language. METHODS Nineteen adults who stutter (AWS) and 20 controls produced spontaneous speech under a baseline condition and two dual task conditions: one involving a sustained attention task, the other involving WM demands. RESULTS Both groups produced fewer stutter-like disfluencies under dual task relative to baseline conditions and this reduction did not differ between the two dual tasks (attention vs. WM). Speech rate and language variables, which were potentially influenced by attention conditions, were not affected by dual tasks in the same way as disfluencies, and appeared to be unassociated with fluency results. CONCLUSIONS Findings indicate that atypical disfluencies decrease when attention is divided, even when secondary task demands are minimal, as they were in the sustained attention task. For simple secondary tasks, fluency changes do not appear to be a byproduct of slowed rate and are not accompanied by observable changes in language. These results demonstrate that simple manipulations of attention can induce measurable effects on aspects of speech production, and may be a useful tool for facilitating fluency in clinical intervention.

Abstract
PURPOSE Individuals who covertly stutter have a unique experience of stuttering that involves concealing the core behaviors of stuttering (e.g., repetitions, prolongations, and blocks). From the listener's perspective, covert stuttering results in minimum typical, overt stuttering behaviors. However, from the speaker's perspective, covert stuttering often increases the cognitive and emotional impact of stuttering. This study explores the speech-language therapy experiences of individuals who covertly stutter in order to improve treatment recommendations and best practice. METHODS This investigation is a qualitative analysis of individuals' speech-language therapy experiences as persons who covertly stutter. Real-time video interviews were conducted with the use of open-ended phenomenological interview questions. Interviews were transcribed and thematic analysis of interview transcripts was conducted to investigate the speech-language therapy experiences of the participants. RESULTS The participants indicated that stuttering therapy was most impactful when it included explicit goals and activities, personalized selection of therapy techniques or strategies beyond fluency techniques, encouraged self-education, and educated those in the person's environment. CONCLUSION The evidence suggests individualized therapy based on each client's unique manifestation of covert stuttering is beneficial; while, fluency-focused stuttering therapy is often incongruent with the needs of persons who covertly stutter. Therapeutic implications and recommendations for speech-language pathologists are discussed.

Abstract
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.

Abstract
PURPOSE The purpose of this study was to examine how the therapeutic alliances (TA) of graduate student clinicians and adult clients who stutter relate to perceived treatment outcomes. METHODS Student clinicians (N = 42) and adult clients who stutter (N = 22) completed a survey assessing their TA strength and perception of treatment outcomes. Responses were analyzed to determine similarities and differences in how clinicians and clients relate the TA to perceptions of treatment effectiveness, progress, and outcome satisfaction. RESULTS Results suggest that clinicians and clients who stutter both relate the TA to treatment outcome, but in different ways. While clinicians associate the TA most with treatment effectiveness and client progress, clients relate the TA most to outcome satisfaction. CONCLUSION Clinicians should be aware that for adult clients who stutter, outcome satisfaction is related to the degree of shared understanding, agreement on daily tasks, and bond they experience with their clinician. To ensure a strong TA and client satisfaction, clinicians should actively seek their clients' perspective regarding TA status.

Abstract
Purpose: Parents have a vital role in the delivery of the Lidcombe Program when treating stuttering in young children. Research into parent experiences and perceptions throughout the Lidcombe Program is currently limited. Qualitative literature indicates that parent experiences and child progress are closely linked with program duration. This preliminary quantitative study examined parent satisfaction with child fluency at three time points. Data from clinic and telehealth delivery of the Lidcombe Program were used to further explore between-group non-inferiority. Method: The data were drawn from a parallel, non-inferiority, randomised controlled trial. Forty-nine children were randomised to the clinic or telehealth group. Parent satisfaction ratings with child fluency, the percentage of syllables stuttered and parent reported severity ratings were measured pre-treatment, 9 months and 18 months post-commencement of treatment. Result: An increase in parent satisfaction paralleled a decrease in stuttering severity across the three time points universally, however, the relationship between parent satisfaction and stuttering severity was not found at every time point. Conclusion: Though a general increase in parent satisfaction was seen as severity decreased, a global assumption on satisfaction cannot be made based on stuttering severity when measured using an ordinal scale.

Abstract
BACKGROUND Multiple factors can influence the working alliance and treatment outcome in speech and language therapy. The 'working alliance' is an important concept in treatment and can be described as the degree to which a treatment dyad is engaged in collaborative, purposive work. To date, relatively little attention has been paid to this concept within speech and language treatment in general, and within stuttering treatment research in particular. AIMS To investigate the role of the working alliance within stuttering treatment, and to evaluate whether the quality of the working alliance correlated with clients' concept of motivation and treatment outcomes 6 months post-therapy. METHODS & PROCEDURES Eighteen adults (21-61 years) participated in this multiple single-case treatment study, with treatment facilitated by an experienced speech and language therapist. The working alliance was investigated using the Working Alliance Inventory-Short Version Revised (WAI-SR), an Extended version of the Client Preferences for Stuttering Treatment (CPST-E), the Overall Assessment of Speakers' Experience of Stuttering-Adult version (OASES-A), the Wright & Ayre Stuttering Self-Rating Profile (WASSP) and the Hospital Anxiety and Depression Scale (HADS). OUTCOMES & RESULTS Analyses demonstrated significant associations between the working alliance and client motivation (r = 0.781) and treatment outcomes (r = 0.644) 6 months post-treatment. The association between client-led goals and therapy tasks appeared particularly important. CONCLUSIONS & IMPLICATIONS The working alliance between speech and language therapists and persons who stutter matters. Within the alliance, the level of client-clinician agreement on treatment goals and therapy tasks may be of greater importance than the bond between client and clinician. Further research with greater numbers of participants is warranted.

Abstract
BACKGROUND The Rotterdam Evaluation Study of Stuttering Therapy randomized trial (RESTART) was seminal, comparing the Lidcombe Program with RESTART Demands and Capacities Model-based treatment (RESTART-DCM) for pre-school age children who stutter. AIMS To critique the methods of the RESTART trial to develop guidelines for its systematic replication and extension. Beyond that, to contribute to the refinement of existing methodological guidelines for early stuttering intervention. METHOD The discussion is organized around methodological issues of primary outcomes, treatment completion, clinician allegiance, treatment fidelity, age exclusions and no-treatment control reasoning. MAIN CONTRIBUTION We recommend six methodological guidelines to guide future clinical trials comparing the Lidcombe Program with RESTART-DCM, which can be applied to clinical trials of other early stuttering intervention methods: (1) incorporate a continuous measure of primary outcome; (2) ensure that all children in clinical trials have completed treatment; (3) eliminate potential bias due to clinician allegiance; (4) establish treatment fidelity within and beyond the clinic; (5) include children younger than 3 years in clinical trials; and (6) establish an estimate of treatment effect size at some stage of treatment development. CONCLUSION In addition to guiding future clinical research comparing RESTART-DCM and Lidcombe Program treatment, these recommendations may extend to influence positively other treatment developments for early stuttering.

Abstract
PURPOSE It is now well established that adults who present to speech clinics for help with stuttering will have an increased risk of having an anxiety disorder, particularly social anxiety disorder. Concomitant psychological problems are known to interfere with the maintenance of the benefits of behavioral speech treatments for stuttering. The current team has developed and trialed a cognitive behavior therapy (CBT) program designed specifically to reduce anxiety in adults who stutter, and trials have shown promise for both an in-clinic version and a standalone internet-based version. The aim of the present study is to determine whether iGlebe, the internet-based version of the team's internet CBT treatment (previously known as CBTPsych), enhances the benefits of behavioral stuttering treatment. METHOD Participants were 32 adults seeking treatment for stuttering. The design was a two-arm randomized experimental trial with blinded outcome assessments at 6 and 12 months post-randomization. Both arms received basic speech-restructuring training to reduce stuttering, without any anxiolytic (anxiety reducing) components. The experimental arm also received 5 months access to iGlebe. RESULTS There was evidence that, at 12 months post-randomization, iGlebe added clinically significant improvements to self-reported stuttering severity and quality of life. The present experimental trial provides the first evidence that the addition of CBT to speech restructuring improves speech outcomes. CONCLUSIONS The present results will be the basis for the development of a comprehensive, internet-based treatment program for anxiety associated with stuttering. Ultimately, it may be possible for such an economical, scalable, and translatable comprehensive treatment model to supplement standard speech-language pathology treatment practices for those who stutter.

Abstract
PURPOSE We previously introduced theStuttering Anticipation Scale (SAS; Jackson, E. S., Gerlach, H., Rodgers, N. H., & Zebrowski, P. M. (2018). My Client Knows That He's About to Stutter: How Can We Address Stuttering Anticipation during Therapy with Young People Who Stutter? Seminars in Speech and Language, 39, 356-370) - a non-standardized self-report measure for children, teens, and adults who stutter (CWS, TWS, AWS) that quantifies how often they engage in 25 commonly reported action responses to anticipation. The purpose of this study was to leverage the SAS to explore the factor structure of action responses to stuttering anticipation. METHODS A total of 121 people who stutter completed the SAS online (27 CWS, 40 TWS, 54 AWS). We used exploratory factor analysis (EFA) to determine the underlying latent variables within the 25 SAS items that characterize how people who stutter respond to anticipation. RESULTS A three-factor model was most appropriate for the data with regard to factor loadings and other model fit indices. The three factors were named: avoidance (17 items), physical change (4 items), and approach (4 items). CONCLUSION Understanding these three types of action responses to anticipation can help guide clinical decision-making by providing a novel framework for clinicians and their clients who stutter to discuss how the client tends to respond to anticipation, and explore ways to facilitate productive responses to anticipation.

Abstract
PURPOSE Voluntary stuttering techniques involve persons who stutter purposefully interjecting disfluencies into their speech. Little research has been conducted on the impact of these techniques on the speech pattern of persons who stutter. The present study examined whether changes in the frequency of voluntary stuttering accompanied changes in stuttering frequency, articulation rate, speech naturalness, and speech effort. METHOD In total, 12 persons who stutter aged 16-34 years participated. Participants read four 300-syllable passages during a control condition, and three voluntary stuttering conditions that involved attempting to produce purposeful, tension-free repetitions of initial sounds or syllables of a word for two or more repetitions (i.e., bouncing). The three voluntary stuttering conditions included bouncing on 5%, 10%, and 15% of syllables read. Friedman tests and follow-up Wilcoxon signed ranks tests were conducted for the statistical analyses. RESULTS Stuttering frequency, articulation rate, and speech naturalness were significantly different between the voluntary stuttering conditions. Speech effort did not differ between the voluntary stuttering conditions. Stuttering frequency was significantly lower during the three voluntary stuttering conditions compared to the control condition, and speech effort was significantly lower during two of the three voluntary stuttering conditions compared to the control condition. CONCLUSIONS Due to changes in articulation rate across the voluntary stuttering conditions, it is difficult to conclude, as has been suggested previously, that voluntary stuttering is the reason for stuttering reductions found when using voluntary stuttering techniques. Additionally, future investigations should examine different types of voluntary stuttering over an extended period of time to determine their impact on stuttering frequency, speech rate, speech naturalness, and speech effort.

Abstract
PURPOSE This study described the proportion of children who stutter who exhibit Attention Deficit Hyperactivity Disorder (ADHD) symptoms, manifesting in inattentive and hyperactive/impulsive behaviours. Children who stutter with these challenging behaviours may not respond as quickly and successfully to stuttering treatment. A preliminary exploration of differences in treatment responsiveness for children with and without ADHD symptoms was undertaken. METHOD Participants were 185 preschool children who stutter who had completed stuttering therapy within 3 months prior to study commencement. Differences between groups of children who stutter with and without elevated ADHD symptoms were investigated, in terms of pre-treatment stuttering features (stuttering severity and typography), demographic variables (age at onset, time between onset and commencement of therapy, family history and sex) and treatment data (post-treatment stuttering severity and number of sessions to achieve discharge criteria). RESULTS One-half (50%) of participants exhibited elevated ADHD symptoms. These children required 25% more clinical intervention time to achieve successful fluency outcomes than children without elevated ADHD symptoms. Findings suggest that more ADHD symptoms, increased pre-treatment stuttering severity, and male sex were associated with poorer responsiveness to stuttering treatment. CONCLUSION The large proportion of children exhibiting elevated ADHD symptoms, and the increase in clinical contact time required in this subgroup to achieve successful fluency outcomes, is suggestive of the need for clinicians to tailor stuttering intervention to address these concomitant behaviour challenges. Findings support the use of careful caseload management strategies to account for individual differences between children, and strengthen prognostic information available to parents and clinicians.

Abstract
PURPOSE The temperament construct of effortful control, an index of self-regulation and resilience, has been found to be predictive of stuttering severity in children and is a potential indicator of clinical prognosis. Evidence supports early intervention for preschool stuttering, and the successful effect of parents as agents of change in their children's stuttering therapy. However, no previous studies have trained parents to improve self-regulation in their children as a component of stuttering therapy. This study aimed to explore the effects of addressing self-regulation, as a component of stuttering treatment, on child fluency as well as parent and child psychosocial outcomes. METHODS This study implemented a preliminary parent administered resilience component in conjunction with stuttering therapy for children who stutter, and compared outcomes to a cohort of children who stutter who received stuttering therapy only. Twenty-eight children who stutter were randomly allocated to one of the two treatment groups. Dependent variables tested pre- and post-treatment included stuttered speech severity, parenting practices, and child resilience indicators. Outcomes were compared between groups at post treatment. RESULTS Stuttered speech severity decreased in both treatment groups. A reduction in behavioural and emotional problems, and increase in resilience was observed in the children who stutter whose parents received the additional resilience component of therapy. Furthermore, a significant improvement in parenting practices was demonstrated in this group. No significant changes in emotional and behavioural problems in children or parents were observed in the group of children who received fluency therapy only. CONCLUSION Results demonstrate that implementation of the resilience component was successful in positively shifting parenting practices and increasing behavioural resilience in children who stutter. This has clinical implications for successfully managing fluency while concurrently targeting the concomitant behavioural and emotional impacts of the disorder on both children and parents, potentially a key future prognostic indicator of the maintenance of fluency outcomes.

Abstract
Background In 2014, Kraft et al. assessed the temperament, home environment, and significant life events of 69 North American children who stutter to examine the combined and compounded effects of these individualized factors on mediating overt stuttering severity. The temperament domain of effortful control was singularly found to be significantly predictive of stuttering severity. Purpose Because of the clinical significance of the initial study's findings, a replication study with a different, larger cohort of children who stutter was warranted to validate the reported outcomes. Method The current study assesses 98 children who stutter, ages 2;4 to 12;6 (years; months, M = 6;7), recruited from Perth, Australia. Results The results support the previous findings of Kraft, Ambrose, and Chon (2014) , with effortful control remaining the sole significant contributor to variability in stuttering severity, as rated by both parents and clinicians. Conclusion These cumulative and consistent outcomes support the need to develop targeted intervention strategies that specifically strengthen aspects of effortful control as a means to support positive therapeutic change in children who stutter.

Abstract
PURPOSE The first purpose was to define the recovery rate in children who stutter in a clinical sample, adding self-report to validate recovery status. The second purpose was to explore whether children who were judged to be recovered showed subjective experiences that might be interpreted as coping behaviors used to control speech fluency. METHODS In this longitudinal study, preschool-age children whose parents consulted a speech-language pathologist about stuttering were followed for 9 years. At follow-up, children's self-reports on stuttering were reported, as well as traditional criteria on recovery (parental and expert judgment). The Overall Assessment of the Speaker's Experience of Stuttering (OASES) was used to collect children's experiences with speaking. RESULTS Eleven of the 15 children (73%) were judged by parents and clinicians to have recovered from stuttering. However, when considering children's self-reports, 9 children (60%) might be considered to have recovered. In addition, 3 children who were judged to be recovered reported experiences with speaking that were uncommon, even compared to children who continued to stutter. CONCLUSION In this exploratory study of a clinical population, the recovery rate in children that received treatment for stuttering appeared to be comparable to a non-clinical population. Considering self-reports can improve validity of assessing the "recovery rate". Moreover, recovery in children may not be effortless; instead, it may be the result of conscious or unconscious coping behavior. Future studies are recommended to consider self-reports to improve validity of recovery, and to document experiences with speaking to explore effortless, spontaneous fluency versus controlled fluency.

Abstract
PURPOSE Qualitative data were obtained from 8 people who stutter about their experiences and changes they perceived following attendance of an intensive group therapy intervention. Measures that related to reductions in stuttering, improved communicative confidence, and impacts on stuttering and quality of life were used to complement the qualitative data. METHOD Eight participants attended a group stuttering modification course for adults who stutter. They reported their experiences of therapy and perceived changes in a focus group immediately after therapy and at a semistructured interview 6 months post-therapy. Participants completed 5 additional quantitative standardized outcome measures at 3 data collection points (before and directly after therapy and 6 months post-therapy). These measures provided information about stuttering severity and frequency, use of avoidance strategies, attitude change, communicative confidence, quality of life, and locus of control. RESULTS Thematic analysis of the qualitative data identified 4 main areas: thoughts, feelings, and behaviors before therapy and motivation for seeking therapy; direct experience of the course; learning outcomes and challenges and solutions for maintaining change; and ways in which attending therapy had made a difference. These reported changes were supported by the quantitative measures that demonstrated improved communicative confidence; increased self-awareness; affective, behavioral, and cognitive changes; reduced use of avoidance strategies; and lower impact of stuttering on quality of life. CONCLUSIONS The qualitative analyses confirmed positive speech and attitude changes consequent on participants' attendance at stuttering modification therapy. These changes, further corroborated by quantitative measures, were linked to reports of improved quality of life. Further research is required to investigate the effectiveness of this form of therapy empirically and from the client's perspective.

Cooke K, Millard SK. The Most Important Therapy Outcomes for School-Aged Children Who Stutter: An Exploratory Study. AMERICAN JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2018; 27:1152-1163.

Abstract
PURPOSE The aim of this article was to identify what school-aged children who stutter consider to be the most important outcomes from therapy. METHOD A Delphi approach was employed for the study. Eighteen participants aged 9-13 years completed a survey, generating 90 statements that would constitute successful therapy outcomes. After categorization and reduction, 79 statements were sent to participants in a second survey to seek consensus on their importance. Fifteen participants aged 8-14 years completed this second survey. Statements with the highest median ratings and smallest standard deviations were retained. RESULTS Twenty-one statements were retained after analysis. These reflected hopes for affective and behavioral change in the young person and in other people after therapy. Important outcomes included, but are not limited to, increased fluency, greater independence, increased confidence at school, others knowing how to support the individual, and communication situations feeling easier. CONCLUSIONS Participants identified a range of outcomes that were important to achieve as a result of speech and language therapy. The findings suggest a need for a more holistic view of what is meant by successful therapy, incorporating improvements in the ability to communicate and participate in daily situations. The findings suggest that an integrated or holistic approach to intervention would be required to achieve these goals and should include significant others from the child's environment. The important statements identified in this study could be used to inform the content of therapy and to evaluate change over time. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.7144205.

Abstract
PURPOSE Stuttering behaviors and moments of stuttering are typically defined by what a listener perceives. This study evaluated participants' perceptions of their own experience of moments of stuttering. METHOD Thirteen adults who stutter participated in a phenomenological qualitative study examining their experience of moments of stuttering. Analysis yielded several common themes and subthemes culminating in an essential structure describing the shared experience. RESULTS Speakers experience anticipation and react in action and nonaction ways. Many speakers experience a loss of control that relates to a lack of a well-formed speech plan or agency. The experience of moments of stuttering changes through therapy, over time, with self-help, and across situations. Many speakers experience so-called typical stuttering behaviors as reactions rather than direct consequences of trying to speak. Interactions with listeners can affect the experience of stuttering. CONCLUSION Although research recognizes that the experience of the stuttering disorder involves more than just speech behaviors, people who stutter experience stuttering behaviors in time as involving more than just the disruption in speech. This finding has implications for both the theoretical understanding of stuttering and the clinical evaluation and treatment of the stuttering disorder.

Abstract
PURPOSE To consider the rationale, methods, and potential benefits of nurturing the growth of resilience in school-aged children who stutter. Stuttering in childhood can have negative psychological consequences for some, including the development of a negative attitude toward their speech from a young age (Vanryckeghem, Brutten, & Hernandez, 2005) and possible co-occurring psychopathology in adolescence and adulthood, in particular, anxiety disorders (Blood, Blood, Maloney, Meyer, & Qualls, 2007; Iverach & Rapee, 2014; McAllister, Kelman, & Millard, 2015). Children who stutter also frequently report teasing and bullying by their peers (Blood & Blood, 2007; Boyle, 2011; Langevin, Packman, & Onslow, 2009), which can have a significant impact on children's confidence and psychological well-being. However, the capacity of children who stutter to cope or "bounce back" from adversity is not routinely explored or incorporated in therapy for stuttering. METHOD This clinical focus article will explore the construct of resilience and consider why it may be important for children who stutter and their parents. A framework for understanding resilience in relation to stuttering is used, drawing from the Reaching In Reaching Out Resiliency Program (for children aged under 8 years and their parents) and the Penn Resiliency Program (for children aged 8 years and over). CONCLUSIONS The role of parents is key in modeling resilient responses to children and creating a resilience-rich environment. As children who stutter may be more vulnerable to adversity, some may benefit from targeted support to build their resilience, in order to enhance their ability to overcome challenges and thrive.

Abstract
PURPOSE The aim of this study was to establish normative data for Polish persons who stutter (PWS) and persons who do not stutter (PWNS) with the adapted version of the Behavior Assessment Battery (BAB; Vanryckeghem & Brutten, 2018) for adults and to investigate whether or not gender and age influenced the results. In addition, the BAB subtests' reliability and validity were examined. METHOD A Polish version of the BAB test procedures, including the Speech Situation Checklist-Emotional Reaction, Speech Situation Checklist-Speech Disruption, Behavior Checklist, and Communication Attitude Test for Adults Who Stutter (Vanryckeghem & Brutten, 2018), were individually administered to 123 adults who stutter and 151 adults who do not stutter between the ages of 17 and 70. RESULTS PWS scored statistically significantly higher on all BAB subtests compared to PWNS. No significant between-groups gender or age difference was detected. The test data indicate high internal validity. The test items correlate well with the total score and significantly differentiate the two groups. The test battery validly differentiates PWS from PWNS with high accuracy. CONCLUSIONS The Polish version of the BAB for adults confirms data collected in previous cross-cultural investigations. The results once again differentiate PWS from PWNS in a powerful way. Compared to PWNS, PWS report significantly more anxiety and speech breakdown when speaking in particular speech situations. They also report their attitude toward speech to be significantly more negative compared to the typical speaker and indicate using a significant number of coping behaviors to avoid or escape difficult speaking conditions. The BAB test battery, in its totality, assists in multidimensional assessment, pre- and posttreatment comparison, and identification of treatment targets based on the answers of PWS to each test item.

Abstract
PURPOSE The Lidcombe program is a treatment for preschool-age children who stutter. Studies indicate that its implementation is not always straightforward. In this study, challenges that parents and speech-language pathologists (SLPs) encounter when implementing the Lidcombe program were identified, and strategies to address them were sought. METHOD In Part 1, Lidcombe program treatment challenges were determined from 4 sources. In Part 2, 7 SLPs with 15 to 23 years of Lidcombe program experience were interviewed to develop strategies to respond to the identified treatment challenges. RESULT A template of the themes and a report with possible strategies are the outcomes of this study. A total of 124 themes were identified, mostly related to the implementation of Lidcombe program procedures. Strategies to deal with these challenges were formulated. CONCLUSIONS This study provides treatment challenges that parents or SLPs may encounter during the Lidcombe program. It also provides strategies that SLPs can suggest to address them. An added contribution of the findings is that SLPs in the clinic can now anticipate the sort of treatment challenges that parents may face. A summary of the findings will be made available on the Australian Stuttering Research Centre website and through the Lidcombe Program Trainers Consortium.

Abstract
PURPOSE Palin Parent-Child Interaction therapy (Kelman & Nicholas, 2008) is an evidence-based intervention for young children who stutter. The evidence consists of multiple single-subject replicated studies, and this demonstrates that the intervention is effective. The aim of this study was to enhance the evidence base by exploring the effectiveness of the therapy with a large cohort of children who stutter. METHOD Children and parents completed a range of assessments at 4 time points: start of therapy and then 3, 6, and 12 months later. The following variables were included: stuttering frequency, child's communication attitude, parents' perception of the impact of the stuttering on the child, the severity of stuttering and its impact on the parents, and their knowledge of stuttering and confidence in managing it. Hierarchical multiple regression analyses were conducted to explore whether the variables are predictive for the outcome "parent knowledge and confidence." In addition, we sought a preliminary view of factors associated with outcome level by separating children into 2 groups according to response to treatment (more successful and less successful). RESULTS The results demonstrated a significant improvement in all variables, and this improvement was maintained for 1 year posttreatment. Measures collected 3 months after the start of therapy showed significant improvement in child attitude to communication, parents' knowledge and confidence in how to manage stuttering, and mothers' ratings of stuttering severity and impact the child's stuttering has on the mothers. By 6 months after therapy onset, there was a significant reduction in stuttering frequency and fathers' perception of severity and their worry about it. Furthermore, these improvements were maintained 1 year posttherapy. Several variables predicted parents' knowledge and confidence 6 months after the start of therapy. Finally, those who made greater improvements had mothers who were more negative in their ratings of severity and worry, and had less knowledge and confidence at the start of therapy. There were no differences between the groups on a range of other variables. CONCLUSIONS The results demonstrate that, over a year, children who attend a course of Palin Parent-Child Interaction show reduced stuttering frequency and a more positive attitude to speech. In addition, parents observe these improvements in the child, feel more confident in managing the stuttering, and are less worried about it. The different times at which specific variables significantly improved provides insight to a process of change over time. Results suggest that parents' ability to notice positive change in fluency and the impact that these observations have on both the child and the family are linked to their confidence in how to support the child. The preliminary findings with regard to response to treatment suggest that children can benefit from this program even with factors that might be predicted to reduce therapy success.

Abstract
PURPOSE The aim of this study was to describe a range of methods used in stuttering therapy for desensitizing parents of children who stutter (CWS). METHOD This clinical tutorial will first briefly explore the rationale and benefit of including parents of CWS of all ages in the therapy process. The construct of desensitization will be defined, and a description will be given of how traditionally it has been incorporated into therapy with adults who stutter and CWS. Research evidence will be presented about the impact of a child's stuttering on parents. The article will then focus on clinical methods for desensitizing parents of CWS using examples of activities conducted in group and individual therapy with parents at the Michael Palin Centre in London with reference to desired outcomes, how to measure them, and how to address potential pitfalls. CONCLUSION Desensitization activities can be implemented with parents of CWS to help them recognize and manage their emotional reactions to their child's stuttering, to support parents to feel knowledgeable and confident in managing their child's stuttering, and ultimately to enhance the child's progress in therapy.

Abstract
PURPOSE The experiences of women who stutter have been underresearched. Clinicians have little guidance from the research literature on issues specific to women who stutter and are likely to have less clinical contact with this group than with men who stutter because of the higher prevalence of stuttering in men. This study explored the experiences of a small group of women who stutter with a particular focus on what the main current issues are and how gender may have influenced experiences with stuttering. METHOD This qualitative study involved recruitment of 9 women who stutter (aged 35-80 years) through a support network of people who stutter in Western Australia. All the women had received some form of speech therapy for stuttering, and they came from diverse cultural backgrounds. Individual, semistructured interviews were conducted, recorded, and transcribed verbatim. Data were managed with NVivo 10, and thematic analysis was used to identify recurring themes across the data. Data were coded independently by the researchers and refined through group discussion. Participants also completed the Overall Assessment of the Speaker's Experience of Stuttering. RESULTS A core theme of "gendered sense of self in society" emerged from the data. This related to 3 broad themes: perceptions of self that were primarily negative, the impact of stuttering on relationships and social connection with others (relationships with family, peers, colleagues, and intimate partners), and the management of stuttering (internal coping, motivations, and experiences with external support). CONCLUSIONS Stuttering has a pervasive impact on all aspects of women's lives and affects how they view themselves, their relationships, their career potential, and their perceptions of how others view them in society. The women interviewed in this study often had negative self-perceptions and felt that their quality of life had been impacted by their stuttering. However, the women's stories and experiences of stuttering were shaped by a broader context of perceived sociocultural expectations of females in society. Strong verbal communication was highlighted as a crucial factor in developing identity and forming relationships. This study highlights the need to be aware of the experiences of, and issues facing, women who stutter for clinicians to be more equipped, focused, and successful in their stuttering interventions for women.

Abstract
PURPOSE Narratives are how people make sense of experiences and give meaning to their lives (Bruner, 1990). Use of narrative therapy (White, 2007) with people who stutter to facilitate the development of preferred stories (as opposed to problem-based stories) has been documented in the literature (Logan, 2013; Ryan, O'Dwyer, & Leahy, 2015). The purpose of this research was to explore the role of narratives in the development of stuttering as a problem for people who stutter. This research sought to describe how these narratives develop and to identify the factors that influence this development. METHOD Narratives from 6 men who stutter were recorded, transcribed, and analyzed using the "Listening Guide" (Brown & Gilligan, 1992). This is a voice-centered relational method. RESULTS Findings indicate interaction between participants' narratives about stuttering and their wider self-narratives. Influencing factors identified include relationships, thoughts and feelings, and the dominant stories about stuttering in relevant social structures. An individual's consciousness of these influences was found to be integral to change in their narratives. CONCLUSIONS The findings point to the importance of considering the environment, including significant relationships and social structures, in our understanding of stuttering. They also provide insights regarding intrapersonal and interpersonal processes, which can influence the development of stuttering or pave the way to stuttering becoming less problematic for the person who stutters.

Abstract
PURPOSE Covert stuttering is a type of stuttering experience that occurs when a person who stutters conceals his or her stutter from others, attempting to be perceived as a nonstuttering individual. A person who covertly stutters experiences the cognitive and emotional elements of stuttering with minimum overt behavioral symptoms. Individuals who covertly stutter are able to provide insight into their experiences in attempting to be perceived as nonstuttering individuals. Covert stuttering is a topic that continues to be in need of a formal definition. The current investigation is utilizing thematic analysis to provide a detail-rich investigation of the paradigm shift from covertly stuttering to overtly stuttering. METHOD The current investigation is a qualitative analysis of individuals' transition process from covertly stuttering to overtly stuttering. Real-time video interviews were conducted with the use of open-ended phenomenological interview questions. Interviews were transcribed, and thematic analysis of interview transcripts was conducted to investigate the covertly to overtly stuttering process for participants. RESULTS The findings provide insight into a paradigm shift that occurs when individuals who covertly stutter begin to outwardly identify themselves and allow for overt stuttering. The primary theme was a paradigm shift in the 6 participants' mindset regarding stuttering; additional details are provided in the subthemes: attending speech therapy, meeting other people who stutter, and a psychological low point. The details of the covert-to-overt stuttering conversion are documented with the use of direct quotations. CONCLUSION The evidence suggests the various intricacies of the experiences of persons who are covert. Clinical implications of these findings for assessing and treating individuals who covertly stutter are discussed.

Abstract
METHOD This clinical discussion paper will explore two aspects of attention in relation to young people who stutter and their parents: (a) what we attend to as human beings and (b) how we attend. It will draw on research and clinical practice informed by CBT and MBIs. Specifically, information-processing theory in CBT explains psychological well-being partly in terms of what individuals focus their attention on, whereas MBIs focus on the relationship between how individuals attend to their internal experiences and their psychological well-being. CONCLUSIONS Although a nascent field, MBIs may be useful as a part of therapy for children and adolescents who stutter. The concepts highlighted by MBIs may also help to resolve some clinical issues.

Abstract
PURPOSE This quasi-experimental design study in Poland evaluated the effects of a course on stuttering for university students and the effects of an educational workshop for public school teachers, both interventions designed to improve attitudes toward stuttering. METHOD Participants (132 in-service teachers and 75 university students) completed the Polish version of the Public Opinion Survey of Human Attributes-Stuttering (St. Louis, 2011) twice, before and after 2 interventions for experimental groups and 3 months apart for control groups. Experimental teachers participated in a 2-hr workshop dedicated to stuttering. Experimental students enrolled in a 1-semester course wherein multiple activities (including the teacher workshop) were included to generate a comprehensive understanding of stuttering. None of the participants in either control group participated in the academic course for students or workshop for teachers. RESULTS Preintervention comparisons for teachers and for students confirmed that participants assigned to either experimental or control groups did not differ significantly on their attitudes toward stuttering. For both experimental teachers and students, the interventions resulted in significant positive changes in stuttering attitudes. Neither control group changed. CONCLUSIONS This experimental study demonstrated that it is possible to positively modify stuttering attitudes of teachers as well as university students. It has implications for the length, content, and experiential components of interventions designed to improve public attitudes toward stuttering.

Abstract
Speaking rhythmically, also known as syllable-timed speech (STS), has been known for centuries to be a fluency-inducing condition for people who stutter. Cantonese is a tonal syllable-timed language and it has been shown that, of all languages, Cantonese is the most rhythmic (Mok, 2009). However, it is not known if STS reduces stuttering in Cantonese as it does in English. This is the first study to investigate the effects of STS on stuttering in a syllable-timed language. Nineteen native Cantonese-speaking adults who stutter were engaged in conversational tasks in Cantonese under two conditions: one in their usual speaking style and one using STS. The speakers' percentage syllables stuttered (%SS) and speech rhythmicity were rated. The rhythmicity ratings were used to estimate the extent to which speakers were using STS in the syllable-timed condition. Results revealed a statistically significant reduction in %SS in the STS condition; however, this reduction was not as large as in previous studies in other languages and the amount of stuttering reduction varied across speakers. The rhythmicity ratings showed that some speakers were perceived to be speaking more rhythmically than others and that the perceived rhythmicity correlated positively with reductions in stuttering. The findings were unexpected, as it was anticipated that speakers of a highly rhythmic language such as Cantonese would find STS easy to use and that the consequent reductions in stuttering would be great, even greater perhaps than in a stress-timed language such as English. The theoretical and clinical implications of the findings are discussed.

Abstract
PURPOSE This report investigates whether parent-reported stuttering severity ratings (SRs) provide similar estimates of effect size as percentage of syllables stuttered (%SS) for randomized trials of early stuttering treatment with preschool children. METHOD Data sets from 3 randomized controlled trials of an early stuttering intervention were selected for analyses. Analyses included median changes and 95% confidence intervals per treatment group, Bland-Altman plots, analysis of covariance, and Spearman rho correlations. RESULTS Both SRs and %SS showed large effect sizes from pretreatment to follow-up, although correlations between the 2 measures were moderate at best. Absolute agreement between the 2 measures improved as percentage reduction of stuttering frequency and severity increased, probably due to innate measurement limitations for participants with low baseline severity. Analysis of covariance for the 3 trials showed consistent results. CONCLUSION There is no statistical reason to favor %SS over parent-reported stuttering SRs as primary outcomes for clinical trials of early stuttering treatment. However, there are logistical reasons to favor parent-reported stuttering SRs. We conclude that parent-reported rating of the child's typical stuttering severity for the week or month prior to each assessment is a justifiable alternative to %SS as a primary outcome measure in clinical trials of early stuttering treatment.

Abstract
See Crinion (doi:10.1093/brain/awy075) for a scientific commentary on this article.Stuttering is a neurodevelopmental condition affecting 5% of children, and persisting in 1% of adults. Promoting lasting fluency improvement in adults who stutter is a particular challenge. Novel interventions to improve outcomes are of value, therefore. Previous work in patients with acquired motor and language disorders reported enhanced benefits of behavioural therapies when paired with transcranial direct current stimulation. Here, we report the results of the first trial investigating whether transcranial direct current stimulation can improve speech fluency in adults who stutter. We predicted that applying anodal stimulation to the left inferior frontal cortex during speech production with temporary fluency inducers would result in longer-lasting fluency improvements. Thirty male adults who stutter completed a randomized, double-blind, controlled trial of anodal transcranial direct current stimulation over left inferior frontal cortex. Fifteen participants received 20 min of 1-mA stimulation on five consecutive days while speech fluency was temporarily induced using choral and metronome-timed speech. The other 15 participants received the same speech fluency intervention with sham stimulation. Speech fluency during reading and conversation was assessed at baseline, before and after the stimulation on each day of the 5-day intervention, and at 1 and 6 weeks after the end of the intervention. Anodal stimulation combined with speech fluency training significantly reduced the percentage of disfluent speech measured 1 week after the intervention compared with fluency intervention alone. At 6 weeks after the intervention, this improvement was maintained during reading but not during conversation. Outcome scores at both post-intervention time points on a clinical assessment tool (the Stuttering Severity Instrument, version 4) also showed significant improvement in the group receiving transcranial direct current stimulation compared with the sham group, in whom fluency was unchanged from baseline. We conclude that transcranial direct current stimulation combined with behavioural fluency intervention can improve fluency in adults who stutter. Transcranial direct current stimulation thereby offers a potentially useful adjunct to future speech therapy interventions for this population, for whom fluency therapy outcomes are currently limited.

Abstract
PURPOSE There is evidence that access to treatment for early stuttering is not available for all who need it. An internet version of the Lidcombe Program for early stuttering (Internet-LP) has been developed to deal with this shortfall. The LP is suitable for such development because it is delivered by parents in the child's everyday environment, with training by a speech-language pathologist. A Phase I trial of Internet-LP Part 1, comprising parent training, is reported here. METHOD Eight parents of pre-schoolers who stutter were recruited and six completed the trial. RESULT Post-trial assessment indicated that the parents scored well for identifying and measuring stuttering and for knowledge about conducting practice sessions, including how to present verbal contingencies during practice sessions. CONCLUSION The results prompted minor adjustments to Part 1 and guided the construction of Part 2, which instructs parents during the remainder of the treatment process.

[PMID: 28778745 DOI: 10.1016/j.jfludis.2017.03.007] [Citation(s) in RCA: 73] [Impact Index Per Article: 12.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2016] [Revised: 01/25/2017] [Accepted: 03/06/2017] [Indexed: 05/14/2023]
Abstract
PURPOSE Stuttering is a disorder that affects millions of people all over the world. Over the past two decades, there has been a great deal of interest in investigating the neural basis of the disorder. This systematic literature review is intended to provide a comprehensive summary of the neuroimaging literature on developmental stuttering. It is a resource for researchers to quickly and easily identify relevant studies for their areas of interest and enable them to determine the most appropriate methodology to utilize in their work. The review also highlights gaps in the literature in terms of methodology and areas of research. METHODS We conducted a systematic literature review on neuroimaging studies on developmental stuttering according to the PRISMA guidelines. We searched for articles in the pubmed database containing "stuttering" OR "stammering" AND either "MRI", "PET", "EEG", "MEG", "TMS"or "brain" that were published between 1995/01/01 and 2016/01/01. RESULTS The search returned a total of 359 items with an additional 26 identified from a manual search. Of these, there were a total of 111 full text articles that met criteria for inclusion in the systematic literature review. We also discuss neuroimaging studies on developmental stuttering published throughout 2016. The discussion of the results is organized first by methodology and second by population (i.e., adults or children) and includes tables that contain all items returned by the search. CONCLUSIONS There are widespread abnormalities in the structural architecture and functional organization of the brains of adults and children who stutter. These are evident not only in speech tasks, but also non-speech tasks. Future research should make greater use of functional neuroimaging and noninvasive brain stimulation, and employ structural methodologies that have greater sensitivity. Newly planned studies should also investigate sex differences, focus on augmenting treatment, examine moments of dysfluency and longitudinally or cross-sectionally investigate developmental trajectories in stuttering.

Abstract
PURPOSE Brain imaging and brain stimulation procedures have now been used for more than two decades to investigate the neural systems that contribute to the occurrence of stuttering in adults, and to identify processes that might enhance recovery from stuttering. The purpose of this paper is to review the extent to which these dual lines of research with adults who stutter have intersected and whether they are contributing towards the alleviation of this impairment. METHOD Several areas of research are reviewed in order to determine whether research on the neurology of stuttering is showing any potential for advancing the treatment of this communication disorder: (a) attempts to discover the neurology of stuttering, (b) neural changes associated with treated recovery, and (c) direct neural intervention. RESULTS AND CONCLUSIONS Although much has been learned about the neural underpinnings of stuttering, little research in any of the reviewed areas has thus far contributed to the advancement of stuttering treatment. Much of the research on the neurology of stuttering that does have therapy potential has been largely driven by a speech-motor model that is designed to account for the efficacy of fluency-inducing strategies and strategies that have been shown to yield therapy benefits. Investigations on methods that will induce neuroplasticity are overdue. Strategies profitable with other disorders have only occasionally been employed. However, there are signs that investigations on the neurology of adults who have recovered from stuttering are slowly being recognized for their potential in this regard.

Abstract
We previously reported speaking-related activity changes associated with assisted recovery induced by a fluency shaping therapy program and unassisted recovery from developmental stuttering (Kell et al., Brain 2009). While assisted recovery re-lateralized activity to the left hemisphere, unassisted recovery was specifically associated with the activation of the left BA 47/12 in the lateral orbitofrontal cortex. These findings suggested plastic changes in speaking-related functional connectivity between left hemispheric speech network nodes. We reanalyzed these data involving 13 stuttering men before and after fluency shaping, 13 men who recovered spontaneously from their stuttering, and 13 male control participants, and examined functional connectivity during overt vs. covert reading by means of psychophysiological interactions computed across left cortical regions involved in articulation control. Persistent stuttering was associated with reduced auditory-motor coupling and enhanced integration of somatosensory feedback between the supramarginal gyrus and the prefrontal cortex. Assisted recovery reduced this hyper-connectivity and increased functional connectivity between the articulatory motor cortex and the auditory feedback processing anterior superior temporal gyrus. In spontaneous recovery, both auditory-motor coupling and integration of somatosensory feedback were normalized. In addition, activity in the left orbitofrontal cortex and superior cerebellum appeared uncoupled from the rest of the speech production network. These data suggest that therapy and spontaneous recovery normalizes the left hemispheric speaking-related activity via an improvement of auditory-motor mapping. By contrast, long-lasting unassisted recovery from stuttering is additionally supported by a functional isolation of the superior cerebellum from the rest of the speech production network, through the pivotal left BA 47/12.

Abstract
PURPOSE Speech in persons who stutter (PWS) is associated with disturbed prosody (speech melody and intonation), which may impact communication. The neural correlates of PWS' altered prosody during speaking are not known, neither is how a speech-restructuring therapy affects prosody at both a behavioral and a cerebral level. METHODS In this fMRI study, we explored group differences in brain activation associated with the production of different kinds of prosody in 13 male adults who stutter (AWS) before, directly after, and at least 1 year after an effective intensive fluency-shaping treatment, in 13 typically fluent-speaking control participants (CP), and in 13 males who had spontaneously recovered from stuttering during adulthood (RAWS), while sentences were read aloud with 'neutral', instructed emotional (happy), and linguistically driven (questioning) prosody. These activations were related to speech production acoustics. RESULTS During pre-treatment prosody generation, the pars orbitalis of the left inferior frontal gyrus and the left anterior insula were activated less in AWS than in CP. The degree of hypo-activation correlated with acoustic measures of dysprosody. Paralleling the near-normalization of free speech melody following fluency-shaping therapy, AWS normalized the inferior frontal hypo-activation, sooner after treatment for generating emotional than linguistic prosody. Unassisted recovery was associated with an additional recruitment of cerebellar resources. CONCLUSIONS Fluency shaping therapy may restructure prosody, which approaches that of typically fluent-speaking people. Such a process may benefit from additional training of instructed emotional and linguistic prosody by inducing plasticity in the inferior frontal region which has developed abnormally during childhood in PWS.

Abstract
INTRODUCTION Neurogenic stuttering is a disorder of neurologic origin in the rhythm of speech during which the patient knows exactly what he wants to say but is unable to because of an involuntary prolongation, cessation or repetition of a sound. AIM To assemble new insights regarding the epidemiology, pathophysiology, diagnosis, evaluation and treatment of neurogenic stuttering. DEVELOPMENT A review of all PubMed and Scopus published articles between January 2000 and September 2016 was performed. Thirty-three publications were analyzed. Neurogenic stuttering is a rare entity whose epidemiological incidence is yet not fully established. It is correlated with several neurological diseases and with several possible localizations within the nervous system. Notwithstanding the recent advances in the understanding of the underlying mechanism, it is not yet possible to establish a single pathophysiological mechanism of neurogenic stuttering. The differential diagnosis is complex and requires the detailed knowledge of other language disorders. The treatment is currently based on specific speech language therapy strategies. CONCLUSION Neurogenic stuttering is a complex disorder which is not fully understood. Additional studies might help to better explain the underlying pathophysiological mechanism and to open doors to novel therapeutic methods.

Abstract
PURPOSE To determine the efficacy of treatment based on Kristin Linklater's technique for vocal preparation for performance for use with people who stutter. METHOD A protocol for a treatment for stuttering involving breathing exercises, relaxation techniques, and focus on awareness was designed by the first author from Linklater's published exercises in her book Freeing the Natural Voice (2006). Four adults who stutter participated in a 12-week, single-case reversal design study. Treatment efficacy was determined by baseline and post-treatment measures on the OASES, self-report naturalness, tension and severity scale, and percentage of stuttering-like disfluency (SLD). Qualitative measures included a daily tension and practice log, a program completion questionnaire, and accounts from the clinicians administering the treatment protocol. RESULTS Three of four participants scored lower on the OASES post-treatment, suggesting that the impact of stuttering on their daily lives had decreased. All four experienced a reduction in the number of SLD counted throughout treatment sessions compared to baseline data. CONCLUSION A treatment for stuttering based on Linklater's work including regulation of breathing, relaxation, and awareness of breath may be effective in improving fluency and decreasing the impact of stuttering and warrants further study.

Abstract
PURPOSE The aim of this study was to evaluate the usefulness of the Speech Situation Checklist for adults who stutter (SSC) in differentiating people who stutter (PWS) from speakers with no stutter based on self-reports of anxiety and speech disruption in communicative settings. The SSC's psychometric properties were examined, norms were established, and suggestions for treatment were formulated. METHOD The SSC was administered to 88 PWS seeking treatment and 209 speakers with no stutter between the ages of 18 and 62. The SSC consists of 2 sections investigating negative emotional reaction and speech disruption in 38 speech situations that are identical in both sections. RESULTS The SSC-Emotional Reaction and SSC-Speech Disruption data show that these self-report tests differentiate PWS from speakers with no stutter to a statistically significant extent and have great discriminative value. The tests have good internal reliability, content, and construct validity. Age and gender do not affect the scores of the PWS. CONCLUSIONS The SSC-Emotional Reaction and SSC-Speech Disruption seem to be powerful measures to investigate negative emotion and speech breakdown in an array of speech situations. The item scores give direction to treatment by suggesting speech situations that need a clinician's attention in terms of generalization and carry-over of within-clinic therapeutic gains into in vivo settings.

Abstract
PURPOSE There is a paucity of evidence to guide treatment for children with co-occurring stuttering and speech sound disorder. Some guidelines suggest treating the two disorders simultaneously using indirect treatment approaches; however, the research supporting these recommendations is over 20 years old. In this clinical case series, we investigate whether these co-occurring disorders could be treated concurrently using direct treatment approaches supported by up-to-date, high-level evidence, and whether this could be done in an efficacious, safe and efficient manner. METHOD Five pre-school-aged participants received individual concurrent, direct intervention for both stuttering and speech sound disorder. All participants used the Lidcombe Program, as manualised. Direct treatment for speech sound disorder was individualised based on analysis of each child's sound system. RESULT At 12 months post commencement of treatment, all except one participant had completed the Lidcombe Program, and were less than 1.0% syllables stuttered on samples gathered within and beyond the clinic. These four participants completed Stage 1 of the Lidcombe Program in between 14 and 22 clinic visits, consistent with current benchmark data for this programme. At the same assessment point, all five participants exhibited significant increases in percentage of consonants correct and were in alignment with age-expected estimates of this measure. Further, they were treated in an average number of clinic visits that compares favourably with other research on treatment for speech sound disorder. CONCLUSION These preliminary results indicate that young children with co-occurring stuttering and speech sound disorder may be treated concurrently using direct treatment approaches. This method of service delivery may have implications for cost and time efficiency and may also address the crucial need for early intervention in both disorders. These positive findings highlight the need for further research in the area and contribute to the limited evidence base.

Abstract
PURPOSE Those who are socially anxious may use safety behaviors during feared social interactions to prevent negative outcomes. Safety behaviors are associated with anxiety maintenance and poorer treatment outcomes because they prevent fear extinction. Social anxiety disorder is often comorbid with stuttering. Speech pathologists reported in a recent publication (Helgadottir, Menzies, Onslow, Packman, & O'Brian, 2014a) that they often recommended procedures for clients that could be safety behaviors. This study investigated the self-reported use of safety behaviors by adults who stutter. METHOD Participants were 133 adults who stutter enrolled in an online cognitive-behavior therapy program. Participants completed a questionnaire about their use of potential safety behaviors when anxious during social encounters. Correlations were computed between safety behaviors and pretreatment scores on measures of fear of negative evaluation and negative cognitions. RESULTS Of 133 participants, 132 reported that they used safety behaviors. Many of the safety behaviors correlated with higher scores for fear of negative evaluation and negative cognitions. CONCLUSIONS Adults who stutter report using safety behaviors, and their use is associated with pretreatment fear of negative evaluation and unhelpful thoughts about stuttering. These results suggest that the negative effects of safety behaviors may extend to those who stutter, and further research is needed.

Abstract
PURPOSE To examine if a community sample of 11-year-old children with persistent stuttering have higher anxiety than children who have recovered from stuttering and nonstuttering controls. METHOD Participants in a community cohort study were categorized into 3 groups: (a) those with persistent stuttering, (b) those with recovered stuttering, and (c) nonstuttering controls. Linear regression modeling compared outcomes on measures of child anxiety and emotional and behavioral functioning for the 3 groups. RESULTS Without adjustment for covariates (unadjusted analyses), the group with persistent stuttering showed significantly increased anxiety compared with the recovered stuttering group and nonstuttering controls. The group with persistent stuttering had a higher number of children with autism spectrum disorder and/or learning difficulties. Once these variables were included as covariates in subsequent analysis, there was no difference in anxiety, emotional and behavioral functioning, or temperament among groups. CONCLUSION Although recognized to be associated with stuttering in clinical samples, anxiety was not higher in school-age children who stutter in a community cohort. It may be that anxiety develops later or is less marked in community cohorts compared with clinical samples. We did, however, observe higher anxiety scores in those children who stuttered and had autism spectrum disorder or learning difficulties. Implications and recommendations for research are discussed.

Abstract
PURPOSE Persons who stutter (PWS) and those with social anxiety disorder may exhibit fear of negative evaluation (FNE) and anxiety in social situations. However, the information processing biases that perpetuate these characteristics have had limited investigation. This study investigated judgment bias in social situations. METHOD Participants included 50 adults who stutter and 45 age- and gender-matched fluent persons who do not stutter (PWNS), who made up the control group. Participants completed the Interpretation and Judgmental Questionnaire (Voncken, Bögels, & deVries, 2003), and threat scores were calculated. RESULTS There were no significant differences between PWS and PWNS in social threat or nonsocial threat scores. When the PWS group was divided on the basis of FNE and compared with PWNS participants without heightened anxiety (n = 35), the PWS with high FNE had significantly higher total social threat scores than the PWS with low FNE. The three groups did not differ in threat ratings for ambiguous or profoundly negative social situations. CONCLUSIONS Judgment bias in PWS is mediated by the magnitude of FNE present; not all PWS exhibit judgment bias for social situations. Treatment implications include the need for psychosocial support addressing the negative impacts on quality of life and restrictions on social engagement that stuttering may cause in some individuals.

Abstract
This study investigated changes in brain function that occurred over a 7-day behavioral intervention for adults who stutter (AWS). Thirteen AWS received the intervention (AWS+), and 13 AWS did not receive the intervention (AWS-). There were 13 fluent controls (FC-). All participants were scanned before and after the intervention. Whole-brain analysis pre-intervention showed significant differences in task-related brain activation between AWS and FC- in the right inferior frontal cortex (IFC) and left middle temporal cortex, but there were no differences between the two AWS groups. Across the 7-day period of the intervention, AWS+ alone showed a significant increase of brain activation in the left ventral IFC/insula. There were no changes in brain function for the other two groups. Further analysis revealed that the change did not correlate with resting-state functional connectivity (RSFC) that AWS showed in the cerebellum (Lu et al., 2012). However, both changes in task-related brain function and RSFC correlated with changes in speech fluency level. Together, these findings suggest that functional reorganization in a brain region close to the left IFC that shows anomalous function in AWS, occurs after a short-term behavioral intervention for stuttering.

Abstract
PURPOSE This study investigated the effects of an intervention to reduce caregivers' articulation rates with children who stutter on (a) disfluency, (b) caregiver and child's articulation rates, and (c) caregiver and child's response time latency (RTL). METHOD Seventeen caregivers and their preschool children who stuttered participated in a group study of treatment outcomes. One speech sample was collected as a baseline, and 2 samples were collected after treatment. Posttreatment samples were of caregivers speaking as they typically would and using reduced articulation rates. RESULTS Caregivers reduced articulation rates significantly in the 2 posttreatment samples, and a significant decrease of stuttering-like disfluencies (SLD) was found in the children in those 2 samples. No direct relationship was found between the caregiver's articulation rate and RTL, and there was a small correlation of RTL with the lower levels of SLD found postintervention. No significant relationships were found between the reduced levels of SLD and articulation rates for either caregivers or children. CONCLUSIONS Results suggest caregivers can be trained to slow their speech, and children increased their fluency at the end of a program designed to slow caregiver articulation. The intentionally slower rate of the caregivers, however, was not significantly related to fluency.

McCulloch J, Swift MC, Wagnitz B. Case file audit of Lidcombe program outcomes in a student-led stuttering clinic. INTERNATIONAL JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2017; 19:165-173. [PMID: 27070028 DOI: 10.3109/17549507.2016.1159336] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2015] [Accepted: 02/24/2016] [Indexed: 06/05/2023]
Abstract
PURPOSE The current study aimed to benchmark clinical outcomes for preschool-aged clients (2;0-5;11 years old) that attended a student-led clinic and undertook the Lidcombe Program. METHOD A case file audit was undertaken for all preschool clients who attended the clinic between February 2008 and February 2013 and commenced the Lidcombe Program. Clients were grouped according to Stage 1 completion. A mixed ANOVA was used to test for differences between the groups in initial and final percentage syllables stuttered (%SS). Associations between case variable factors and treatment duration were investigated using Pearson correlations. RESULT Clients who completed Stage 1 had final %SS and severity rating (SR) scores comparable to the literature; however, the median Stage 1 duration was greater. Over half of the clients (57%) withdrew prior to completing Stage 1. These clients had a significantly higher %SS at final treatment session than their completing peers. Initial %SS and SR scores were the only case variables associated with treatment duration. CONCLUSION Students can achieve the same short-term treatment outcomes for children who stutter using the Lidcombe Program as the current published literature; however, treatment duration is greater and may impact completion. Implications of this for clinical education are discussed.

Sakai N, Chu SY, Mori K, Yaruss JS. The Japanese version of the overall assessment of the speaker's experience of stuttering for adults (OASES-A-J): Translation and psychometric evaluation. JOURNAL OF FLUENCY DISORDERS 2017; 51:50-59. [PMID: 28212720 DOI: 10.1016/j.jfludis.2016.11.002] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2016] [Revised: 09/16/2016] [Accepted: 11/06/2016] [Indexed: 06/06/2023]
Abstract
PURPOSE This study evaluates the psychometric performance of the Japanese version of the Overall Assessment of the Speaker's Experience of Stuttering for Adults (OASES-A), a comprehensive assessment tool of individuals who stutter. METHODS The OASES-A-J was administered to 200 adults who stutter in Japan. All respondents also evaluated their own speech (SA scale), satisfaction of their own speech (SS scale) and the Japanese translation version of the Modified Erickson Communication Attitude scale (S-24). The test-retest reliability and internal consistency of the OASES-A-J were assessed. To examine the concurrent validity of the questionnaire, Pearson correlation was conducted between the OASES-A-J Impact score and the S-24 scale, SA scale and SS scale. In addition, Pearson correlation among the impact scores of each section and total were calculated to examine the construct validity. RESULTS The OASES-A-J showed a good test-retest reliability (r=0.81-0.95) and high internal consistency (α>0.80). Concurrent validity was moderate to high (0.55-0.75). Construct validity was confirmed by the relation between internal consistency in each section and correlation among sections' impact scores. Japanese adults showed higher negative impact for 'General Information', 'Reactions to Stuttering' and 'Quality of Life' sections. CONCLUSION These results suggest that the OASES-A-J is a reliable and valid instrument to measure the impact of stuttering on Japanese adults who stutter. The OASES-A-J could be used as a clinical tool in Japanese stuttering field.

[PMID: 28212718 DOI: 10.1016/j.jfludis.2016.11.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2016] [Revised: 10/30/2016] [Accepted: 11/06/2016] [Indexed: 06/06/2023]
Abstract
PURPOSE The purpose of this study was to evaluate the relationship between stuttering severity, psychological functioning, and overall impact of stuttering, in a large sample of adolescents who stutter. METHOD Participants were 102 adolescents (11-17 years) seeking speech treatment for stuttering, including 86 boys and 16 girls, classified into younger (11-14 years, n=57) and older (15-17 years, n=45) adolescents. Linear regression models were used to evaluate the relationship between speech and psychological variables and overall impact of stuttering. RESULTS The impact of stuttering during adolescence is influenced by a complex interplay of speech and psychological variables. Anxiety and depression scores fell within normal limits. However, higher self-reported stuttering severity predicted higher anxiety and internalizing problems. Boys reported externalizing problems-aggression, rule-breaking-in the clinical range, and girls reported total problems in the borderline-clinical range. Overall, higher scores on measures of anxiety, stuttering severity, and speech dissatisfaction predicted a more negative overall impact of stuttering. CONCLUSION To our knowledge, this is the largest cohort study of adolescents who stutter. Higher stuttering severity, speech dissatisfaction, and anxiety predicted a more negative overall impact of stuttering, indicating the importance of carefully managing the speech and psychological needs of adolescents who stutter. Further research is needed to understand the relationship between stuttering and externalizing problems for adolescent boys who stutter.
