Purpose: We aimed to cross-sectionally describe the impact of stuttering on persons who stutter (PWS): children, adolescents, and young adults. Based on previous research on PWS and psychosocial health in the general population, we hypothesized that (a) the adverse impact of stuttering in PWS would be larger among adolescents than children and young adults and that (b) females, especially adolescent females, would report being more adversely impacted by their stuttering than males.

Method: We pooled samples of Swedish PWS, obtaining 162 individuals (75 females and 87 males), aged 7-30 years. We measured the impact of stuttering using age-relevant versions of the Overall Assessment of the Speaker's Experience of Stuttering (OASES). The relationship between OASES score, age, and sex was described using a polynomial model with an interaction term between age and sex to allow for potential differences between females and males' age-related curves.

Results: The average trends were that (a) the impact of stuttering was greater for the adolescents than for the children and young adults, and (b) females, especially adolescent females, were on average more impacted by their stuttering than males. Taking self-reported speech fluency into account did not change this pattern.

Conclusions: In line with findings on psychosocial health, communication attitude, and self-esteem in the general population, the impact of stuttering seems to be particularly adverse among adolescents, especially female adolescents. Thus, clinicians need to be aware of the risk that young girls who stutter may develop a negative attitude to speech and communication, and this should also be communicated to caregivers and teachers.

People who stutter learn to anticipate many of their overt stuttering events. Despite the critical role of anticipation, particularly how responses to anticipation shape stuttering behaviors, the neural bases associated with anticipation are unknown. We used a novel approach to identify anticipated and unanticipated words, which were produced by 22 adult stutterers in a delayed-response task while hemodynamic activity was measured using functional near infrared spectroscopy (fNIRS). Twenty-two control participants were included such that each individualized set of anticipated and unanticipated words was produced by one stutterer and one control participant. We conducted an analysis on the right dorsolateral prefrontal cortex (R-DLPFC) based on converging lines of evidence from the stuttering and cognitive control literatures. We also assessed connectivity between the R-DLPFC and right supramarginal gyrus (R-SMG), two key nodes of the frontoparietal network (FPN), to assess the role of cognitive control, and particularly error-likelihood monitoring, in stuttering anticipation. All analyses focused on the five-second anticipation phase preceding the go signal to produce speech. The results indicate that anticipated words are associated with elevated activation in the R-DLPFC, and that compared to non-stutterers, stutterers exhibit greater activity in the R-DLPFC, irrespective of anticipation. Further, anticipated words are associated with reduced connectivity between the R-DLPFC and R-SMG. These findings highlight the potential roles of the R-DLPFC and the greater FPN as a neural substrate of stuttering anticipation. The results also support previous accounts of error-likelihood monitoring and action-stopping in stuttering anticipation. Overall, this work offers numerous directions for future research with clinical implications for targeted neuromodulation.

Background: Stuttering is a multifaceted speech disorder that affects the interpersonal communication. It has a significant psychosocial impact on individuals who stutter and on their families. Stuttering is associated with substantial psychosocial morbidity, including social or generalized anxiety, stigmatization or discrimination, impaired self-image, and poor quality of life. Psychosocial morbidity, such as the one reported among stuttering individuals, may provoke suicidal ideation that varies with gender, age, geographic region, and psychosocial reality. The present research aimed to determine the association between stuttering and psychosocial complications in Saudi Arabian individuals.

Materials and methods: This study targeted a total of 107 male patients with stuttering. Only 59 of them fulfilled both inclusion and exclusion criteria. The researchers formulated a valid questionnaire to obtain quantifiable data for analysis. The questionnaire consisted of 76 questions spanning various domains. Following the data collection, a quantitative analysis was carried out.

Results: A total of 79.5% of the participants were adolescents or young adults between the ages of 16 and 26. Among them, 17.8% had a later onset of stuttering. The age of onset tended to be higher than 5 years, with over 80% of respondents reporting an age of onset in the last 5 years of their age. Among the participants, 57.6% reported a positive family history of stuttering.

Conclusions: The present study reports that patients who stutter (PWS) are at a higher risk of developing negative thoughts leading to suicidal attempts due to social anxiety and depression. Therefore, future studies should be designed to establish the relationship between stuttering and suicidal thoughts in order to establish policies that may improve the quality of life of those who stutter.

Attributes that affect the choice of treatment for preschool age children who stutter: an observational study - INFANTIL / TERAPIA

Folia Phoniatr Logop. 2022 Nov 16. Online ahead of print.

Introduction: Little is known about the clinical decision-making process that speech-language pathologists( (SLPs) make when they decide which treatment approach they will use with Preschool age Children who Stutter (PCWS). Frequently used approaches are the Lidcombe Program, RESTART-DCM, Mini-KIDS, the Palin Parent-Child Interaction program and the Social-Cognitive Behaviour Therapy. In this study, we explored which attributes play a role in the complex process that precedes this clinical decision. We also explored if SLPs from the Netherlands, who are expected to follow the recommendations formulated in the Dutch professional stuttering guidelines, use different treatment approaches than SLPs from Belgium, who do not have specific guidelines to follow. Finally, we explored whether the number of years of experience of SLPs had an impact on the choice for treatment.

Methods: This study used an observational design in which 36 SLPs, additionally qualified in the treatment of stuttering, completed a questionnaire. The SLPs spoke Dutch, resided in the Netherlands or Belgium and used more than one treatment approach for PCWS in their standard practice.

Results: The following attributes affected the choice for treatment approach of most SLPs: (1) the child's reactions to the stuttering, (2) the child's language (and speech) skills, (3) the child's age, (4) the family's lifestyle, (5) the parent's ease to understand a treatment approach as judged by the SLPs and (6) the amount and quality of published research-based evidence. The decision-making of experienced SLPs is significantly more affected by the child's stuttering severity and time since onset compared to less experienced SLPs (both U = 90, p = .05). Dutch SLPs did not take other attributes into account than Belgian SLPs.

Discussion/conclusion: This study was a first attempt to explore which attributes affect the decision for a specific treatment. Further prospective research is needed.

Purpose: This study determined whether adults who stutter (AWS) exhibit deficits in responding to an auditory feedback timing perturbation, and whether external timing cues, which increase fluency, attenuate any disruptions due to altered temporal auditory feedback.

Methods: Fifteen AWS and sixteen adults who do not stutter (ANS) read aloud a multisyllabic sentence either with normal pacing or with each syllable paced at the rate of a metronome. On random trials, an auditory feedback timing perturbation was applied, and timing responses were compared between groups and pacing conditions.

Results: Both groups responded to the timing perturbation by delaying subsequent syllable boundaries, and there were no significant differences between groups in either pacing condition. Furthermore, no response differences were found between normally paced and metronome-paced conditions.

Conclusion: These findings are interpreted as showing that 1) AWS respond normally to pure timing perturbations, and 2) metronome-paced speech has no effect on online speech timing control as assessed in the present experiment.

Boston University, Boston, MA 02215, USA.


Purpose: Prior work has shown that Adults who stutter (AWS) have reduced and delayed responses to auditory feedback perturbations. This study aimed to determine whether external timing cues, which increase fluency, resolve auditory feedback processing disruptions.

Methods: Fifteen AWS and sixteen adults who do not stutter (ANS) read aloud a multisyllabic sentence either with natural stress and timing or with each syllable paced at the rate of a metronome. On random trials, an auditory feedback formant perturbation was applied, and formant responses were compared between groups and pacing conditions.

Results: During normally paced speech, ANS showed a significant compensatory response to the perturbation by the end of the perturbed vowel, while AWS did not. In the metronome-paced condition, which significantly reduced the disfluency rate, the opposite was true: AWS showed a significant response by the end of the vowel, while ANS did not.

Conclusion: These findings indicate a potential link between the reduction in stuttering found during metronome-paced speech and changes in auditory motor integration in AWS.

Rhythm perception deficits have been linked to neurodevelopmental disorders affecting speech and language. Children who stutter have shown poorer rhythm discrimination and attenuated functional connectivity in rhythm-related brain areas, which may negatively impact timing control required for speech. It is unclear whether adults who stutter (AWS), who are likely to have acquired compensatory adaptations in response to rhythm processing/timing deficits, are similarly affected. We compared rhythm discrimination in AWS and controls (total n = 36) during fMRI in two matched conditions: simple rhythms that consistently reinforced a periodic beat, and complex rhythms that did not (requiring greater reliance on internal timing). Consistent with an internal beat deficit hypothesis, behavioral results showed poorer complex rhythm discrimination for AWS than controls. In AWS, greater stuttering severity was associated with poorer rhythm discrimination. AWS showed increased activity within beat-based timing regions and increased functional connectivity between putamen and cerebellum (supporting interval-based timing) for simple rhythms.

Purpose: Exploring Australian pre-service primary teachers' knowledge, attitudes, and classroom strategies regarding stuttering provides speech-language pathologists (SLPs) with information that can facilitate enhanced outcomes for school-aged children who stutter.
Method: In this exploratory descriptive cross-sectional study, 51 final-year Bachelor of Education (Primary) students enrolled at an Australian university completed an online survey about stuttering.

Result: Responses demonstrated positive and negative beliefs. Seventy-four per cent of pre-service teachers believed that stuttering has a psychological aetiology and that students who stutter are more likely to be shy or anxious. Participants agreed that their reactions and support offered would largely be based on their assumptions rather than knowledge.

Conclusion: Pre-service primary teachers share similar misconceptions and unhelpful attitudes towards stuttering with previously evaluated populations. Implications for SLPs are discussed.

Purpose: Effective early intervention is recommended to ameliorate the potential long term negative effects of stuttering. Efficacious treatments are available, but speech-language pathologists (SLPs) report finding implementation to be challenging due to a range of clinician, client and clinical context factors. Previous survey-based research has found that SLPs lack self-efficacy working with CWS, however the reasons contributing to this are not well understood. This study presents the first in-depth analysis of the current practices and perceptions of SLPs working with children who stutter (CWS).

Methods: In this qualitative study 18 Australian SLPs who provide services to CWS were interviewed using a semi-structured interview approach. Data were analysed using reflexive thematic analysis.

Results: The thematic analysis identified four themes: (1) A stronger sense of self-efficacy is needed in stuttering management compared to other areas of clinical practice; 2) SLPs' sense of self-efficacy in stuttering management is influenced by early career experiences, client factors and the practice context; 3) Professional development and collaboration strengthen self-efficacy; and 4) Parental involvement and engagement are crucial to treatment success.

Conclusion: SLP self-efficacy for working with CWS appears a critical factor in the provision of effective management for this population. This study provides an in-depth analysis of the role of SLP self-efficacy and the factors that influence it.

Can Stoicism inspire stuttering intervention? The clinical usefulness of an ancient philosophy - TERAPIA

Int J Lang Commun Disord. 2022 Dec 21. Online ahead of print.


Amy Connery, Andrea E Cavanna, Ross Coleman

Trinity College Dublin, Ireland; BSMHFT & University of Birmingham, Birmingham, UK; Aston University, Birmingham, UK; University College London, London, UK.


Background: A range of psychotherapies are effective in managing an individual's personal reactions to stuttering and reducing the impact stuttering has on their lives. Many of these therapies, such as cognitive behavioural therapy, have their origins in Stoicism, an ancient Greek philosophy founded in 301 bce. Stoicism remains a relatively unexplored topic in the psychotherapy and speech and language therapy literatures.

Aims: This paper aims to highlight the potential benefits of integrating Stoic principles and techniques into stuttering intervention.

Methods: This aim is achieved through a discussion on Stoic philosophy and the range of techniques that have informed modern evidence-based psychotherapies that are effective with the stuttering population.

Main contribution: This paper initiates an important conversation on the usefulness of Stoicism to the field of stuttering. Key recommendations are provided for the integration of Stoic philosophy into future clinical and research practice related to stuttering.

Conclusions: Stoicism offers philosophical guidance for the art of living, but also provides a range of strategies and practical techniques that have potential to expand the clinical toolkit of modern psychotherapy and speech and language therapy. Scientific validation of the clinical application of Stoicism is recommended to exploit its effectiveness with the stuttering population.

What this paper adds: What is already known on the subject Stoicism is an ancient philosophy that has informed modern-day psychotherapies including cognitive behavioural therapy (CBT) and acceptance and commitment therapy (ACT). Such therapies are recommended for use with individuals who stutter to target their personal reactions to stuttering and reduce any adverse impacts on their lives. What this paper adds to existing knowledge This paper discusses the principles and techniques of Stoicism with reference to how they align with modern psychotherapeutic approaches and speech and language therapy interventions used with individuals who stutter. Clinical implications and directions for future research are also presented. What are the potential or actual clinical implications of this work? Speech and language therapists (SLTs) are recommended to continue their use of psychotherapies such as CBT and ACT with individuals who stutter. In addition, SLTs are advised to explore Stoicism and its range of techniques to better understand the philosophical underpinnings of evidence-based psychotherapies and to expand their clinical toolkit.

Cognitive flexibility in younger and older children who stutter - PROCEDURAL

Front Psychol. 2022 Nov 18;13:1017319.


Maria Paphiti, Kurt Eggers

University of Turku, Turku, Finland, Ghent University, Ghent, Belgium; Thomas More University College, Antwerp, Belgium.


Purpose: Recent research findings suggest possible weaknesses in cognitive flexibility (CF) in children who stutter (CWS) when compared to children who do not stutter (CWNS). Studies so far, have been conducted with either younger (3-6 years old) or older children (6-12 years old) with a variety of measures. The purpose of the present study was to investigate CF with the use of a single behavioral measure across a broader age range (4-10 years old).

Methods: Participants were 37 CWS (mean age = 6.90 years) and 37 age-and gender-matched CWNS (mean age = 6.88 years), divided in a younger (below 7 years) and older (above 7 years) age group. All participants undertook a computerized visual set-shifting task consisting of three blocks. CF was evaluated through across-and within-block comparisons of the actual response speed and accuracy values. In addition, mixing-and set-shifting-costs were evaluated based on the mean response speed and accuracy.

Results: All participants showed expected mixing-and set-shifting-costs. Only the within-block analyses yielded significant between (sub)group differences. Investigation of the block × classification group × age group interactions showed that older CWS had larger set-shifting-costs (slowed down more and made more errors) compared to older CWNS.

Conclusion: While all participants required more time during set-shifting trials, only the older CWS (7-10 years old), and not younger CWS, were slower and made more errors. This finding corroborates previous findings in CWS of a similar age and could possibly point to a role of CF in stuttering persistence.

Communicative Fluency and the Experience of Stuttering: A Viewpoint - CONCEITO

J Speech Lang Hear Res. 2022 Sep 12;1-8. Online ahead of print.


Evan Usler

University of Delaware, Newark.


Purpose: Despite ambiguity in meaning and usage, "fluency" has played a central role in the understanding and treatment of developmental stuttering. The appropriateness of the term fluency in association with so-called fluency disorders, such as stuttering, has recently been questioned. The purpose of this article is to propose that fluency is best conceptualized as the efficiency of goal-directed action through cybernetic function. Spoken utterances are examples of sequences of action for the fulfillment of a hierarchy of nested and increasingly abstract social goals, including behaviors (e.g., introducing oneself) and values (e.g., being a sociable person). In contrast, some moments of speech disfluency, such as stuttering disfluencies, are inefficiencies in goal-directed action that may or may not hinder the fulfillment of higher level communicative behaviors and values, described here as communicative fluency.

Conclusions: The concept of communicative fluency refers to the continual, reliable, and upward fulfillment of increasingly abstract social goals in the form of communicative actions, behaviors, and values. This expanded conceptualization of fluency beyond simply speech production has the potential to be a useful indicator of psychosocial well-being for individuals who stutter.

Complex response inhibition and cognitive flexibility in school-aged Cypriot-Greek-speaking children who stutter - PROCEDURAL

Maria Paphiti, Eira Jansson-Verkasalo, Kurt Eggers

University of Turku, Turku, Finland; Ghent University, Ghent, Belgium; Thomas More University College, Antwerp, Belgium.


Purpose: Over the last few years, research findings have suggested limitations in executive function (EF) of children who stutter (CWS) with the evidence being more consistent in studies with preschoolers (3-6 years old) than in studies with school-aged children (6-12 years old). The purpose of the current study was to assess complex response inhibition and cognitive flexibility in school-aged CWS and their non-stuttering peers.

Methods: Participants, 19 CWS (mean age = 7.58 years, range 6.08-9.17) and 19 age-and gender-matched children who do not stutter (CWNS; mean age = 7.58 years, range 6.08-9.33), completed a visual task consisting of three task blocks. Analyses were based on response times and error percentages during the different task blocks.

Results: All participants showed expected performance-costs in task block comparisons targeting complex response inhibition and cognitive flexibility. Significant group differences were found in measures of cognitive flexibility with CWS performing slower compared to CWNS (p = 0.02). Additionally, significant block × group interactions demonstrated that CWS, compared to CWNS, slowed down more (i.e., higher performance-cost) under both complex response inhibition (p = 0.049) and cognitive flexibility task conditions (p = 0.04 for no-set-shifting and p = 0.02 for set-shifting).

Conclusion: These results are in line with some of the previous findings in school-aged CWS and suggest that CWS present lower performance in complex response inhibition and cognitive flexibility task conditions when compared to their non-stuttering peers.

Hope Gerlach-Houck, Kristel Kubart, Eilidh Cage

Western Michigan University, Kalamazoo; American Institute for Stuttering, New York, NY; University of Stirling, United Kingdom.


Purpose: The purpose of this study was to explore experiences with concealing stuttering in children and young people who stutter based on recollections from adults. In addition, we explored how school-based speech therapists can be helpful or unhelpful to children who are concealing stuttering from the perspective of adults who stutter.

Method: Thirty adults who stutter, who previously or currently conceal stuttering, participated in semistructured interviews exploring their early experiences with hiding stuttering. Purposeful and random sampling was used to diversify experiences and opinions. Reflexive thematic analysis was used to develop themes and subthemes to describe participants' experiences.

Results: All participants in the study reported beginning to conceal stuttering at 18 years of age or younger, with more than two thirds sharing that they began in elementary school. Participants reported that exposure to implicit and explicit ableist messaging about stuttering and traumatic social experiences at school contributed to their inclination to hide disfluencies. Many participants described concealment as a strategy for protecting themselves from stigma. Several participants condemned fluency shaping, calling it harmful and likening it to teaching concealment. Participants believed that speech therapists could be helpful by promoting safe and supportive school environments and by being responsive to the social and emotional challenges that can accompany speaking differently and navigating stigma at school.

Conclusions: Some children who stutter may attempt to protect themselves from stigma by concealing their disfluencies, but doing so can feel isolating and confusing. Speech therapists can play an important role in making the school environment safer and more supportive for children who stutter.

Background: Late-Onset Tay-Sachs (LOTS) disease is a rare, progressive neurological condition that can dramatically affect the life of these patients. The diagnosis of LOTS is easily missed because of the multifaced presentation of these patients, who can initially be assessed by neuromuscular or movement disorder specialists, or psychiatrists. Clinical trials are now becoming available for LOTS. Therefore, early diagnosis can be detrimental for these patients and for insuring informative research outcomes.

Methods: We characterized a cohort of nine patients with LOTS through a detailed clinical and video description. We then reviewed the available literature regarding the clinical description of patients with LOTS. Our findings were summarized based on the predominant phenotype of presentation to highlight diagnostic clues to guide the diagnosis of LOTS for different neurology specialists (neuromuscular, movement disorders) and psychiatrist.

Results: We described a cohort of 9 new patients with LOTS seen at our clinic. Our literature review identified 76 patients mainly presenting with a neuromuscular, cerebellar, psychiatric, stuttering, or movement disorder phenotype. Diagnostic tips, such as the triceps sign, distinct speech patterns, early psychiatric presentation and impulsivity, as well as neurological symptoms (cerebellar or neuromuscular) in patients with a prominent psychiatric presentation, are described.

Discussion: Specific diagnostics clues can help neurologists and psychiatrists in the early diagnosis of LOTS disease. Our work also represent the first video presentation of a cohort of patients with LOTS that can help different specialists to familiarize with these features and improve diagnostic outcomes.

Highlights: Late-Onset Tay-Sachs (LOTS) disease, a severe progressive neurological condition, has multifaced presentations causing diagnostic delays that can significantly affect research outcomes now that clinical trials are available. We highlight useful diagnostic clues from our cohort (including the first video representation of a LOTS cohort) and comprehensive literature review.

Differences in implicit motor learning between adults who do and do not stutter - PSICOMOTOR

Neuropsychologia. 2022 Aug 2;108342. Online ahead of print.

Implicit learning allows us to acquire complex motor skills through repeated exposure to sensory cues and repetition of motor behaviours, without awareness or effort. Implicit learning is also critical to the incremental fine-tuning of the perceptual-motor system. To understand how implicit learning and associated domain-general learning processes may contribute to motor learning differences in people who stutter, we investigated implicit finger-sequencing skills in adults who do (AWS) and do not stutter (ANS) on an Alternating Serial Reaction Time task. Our results demonstrated that, while all participants showed evidence of significant sequence-specific learning in their speed of performance, male AWS were slower and made fewer sequence-specific learning gains than their ANS counterparts. Although there were no learning gains evident in accuracy of performance, AWS performed the implicit learning task more accurately than ANS, overall. These findings may have implications for sex-based differences in the experience of developmental stuttering, for the successful acquisition of complex motor skills during development by individuals who stutter, and for the updating and automatization of speech motor plans during the therapeutic process.

Disfluency-Affirming Therapy for Young People Who Stutter: Unpacking Ableism in the Therapy Room - INFANTIL / SOCIAL

Lang Speech Hear Serv Sch. 2022 Oct 24;1-6. Online ahead of print.


Vivian Sisskin

University of Maryland, College Park.


Purpose: Ableist messages are conveyed early in the life of a stutterer and are amplified throughout the school-age years. Increased recognition of the benefits of acceptance-based therapies for positive long-term outcomes has changed the narrative about stuttering and stutterers. Speech-language therapists are resonating with the ideas that "it is okay to stutter," socioemotional aspects of stuttering must be considered, and support and community are valuable. Despite the shift in understanding, messages conveyed to students and parents commonly encourage suppression of stuttering and masking of one's stuttering identity. The purpose of this article was to (a) expose unintentional ableist messages that perpetuate stigma and feeling "othered" in the therapy relationship and (b) offer suggestions for congruent messaging in stuttering therapy.

Conclusions: Ableism in stuttering therapy contributes to the physical struggle and socioemotional challenges experienced by stutterers. The author offers ideas for revisioning therapy outcomes, language, and messaging to students to encourage a congruent, disfluency-affirming culture in schools and community. Introspection and advocacy by both therapists and the broader professional community, in collaboration with young people who stutter, will serve to reduce the stigma that fuels many of the daily challenges faced by school-age children who stutter.

Inferior frontal cortex pars opercularis (IFCop) features a distinct cerebral dominance and vast functional heterogeneity. Left and right IFCop are implicated in developmental stuttering. Weak left IFCop connections and divergent connectivity of hyperactive right IFCop regions have been related to impeded speech. Here, we reanalyzed diffusion magnetic resonance imaging data from 83 children (41 stuttering). We generated connection probability maps of functionally segregated area 44 parcels and calculated hemisphere-wise analyses of variance. Children who stutter showed reduced connectivity of executive, rostral-motor, and caudal-motor corticostriatal projections from the left IFCop. We discuss this finding in the context of tracing studies from the macaque area 44, which leads to the need to reconsider current models of speech motor control. Unlike the left, the right IFCop revealed increased connectivity of the inferior posterior ventral parcel and decreased connectivity of the posterior dorsal parcel with the anterior insula, particularly in stuttering boys. This divergent connectivity pattern in young children adds to the debate on potential core deficits in stuttering and challenges the theory that right hemisphere differences might exclusively indicate compensatory changes that evolve from lifelong exposure. Instead, early right prefrontal connectivity differences may reflect additional brain signatures of aberrant cognition-emotion-action influencing speech motor control.

Introduction: There is increasing evidence that connects developmental stuttering to attention. However, findings have represented contradiction. Therefore, this study was conducted to investigate the possible relationship between stuttering and attention in resting and undertask conditions.

Methods: In a cross-sectional study26 right-handed AWS (adults who stutter) and 25 matched fluent speakers were enrolled. Demographic data were collected, and the Beck anxiety inventory (BAI) was filled out for all participants. Then, QEEG was conducted, followed by IVA2. CPT test for all subjects. Finally, data were analyzed using SPSS software version 16.

Results: AWS indicated significantly weaker auditory focus attention in the task (p = .02) than the control group, while a similar resting-state EEG marker of attention was found between groups (p > .05). Moreover, attention was not correlated between the two conditions (p > .05).

Conclusion: The EEG marker of attention did not necessarily designate the attentional performance of AWS under the task. Furthermore, attentional skills could be considered in the assessment and therapeutic programs of at least some groups of AWS.

Objectives: Stuttering is a common problem at all ages that is required to be treated since childhood. Atomoxetine is currently used for the treatment of attention deficit hyperactivity disorder (ADHD). It can be effective for the treatment of stuttering due to its selective inhibition of norepinephrine reuptake and dopaminergic properties. Therefore, this randomized controlled trial aimed to evaluate the effect of atomoxetine on children's stuttering.

Materials & methods: The children aged 4-12 years and diagnosed with stuttering, referred to Pediatric Neurology and Psychology clinics , were randomly divided into experimental (n=50) and control (n=50) groups. One group received atomoxetine plus speech therapy, and the other group received only speech therapy. Both groups completed the Stuttering Severity Instrument-Fourth Edition at the baseline (on the first visit) and 3 months after the intervention. The results were compared between the two groups using SPSS software (version 21).

Results: Most of the children (67%) were male. Moreover, 24%, 46%, and 30% of the subjects were within the age ranges of < 60, 60-95, and > 95 months, respectively. Nearly half of the patients (52%) had a positive family history of stuttering. Stuttering severity was the highest within the age range of 60-95 months, in left-handed children, in those who used formula, and in those who felt insecure in the family; however, there was no difference in stuttering severity based on child's gender, concomitant ADHD, multilingualism, facial or movement tics, sleeping hours, and using teats. The mean stuttering severity reduced in both groups (P<0.001), with a greater decrease in the experimental group, compared to that of the control group (P=0.011).

Conclusion: Atomoxetine plus speech therapy is effective for the treatment of children's stuttering and can be used as a complementary treatment strategy in such patients.

Electrodermal Activity of Preschool-Age Children Who Stutter During a Child-Friendly Stroop Paradigm - INFANTIL / EMOCIONAL

Am J Speech Lang Pathol. 2022 Oct 4;1-18. Online ahead of print.


Heather D Salvo, Hayley S Arnold

Purpose: The aim of the study was to assess whether emotional reactivity, indexed by a distinct physiological measure of sympathetic activation, differs between preschool-age children who stutter (CWS) and preschool-age children who do not stutter (CWNS) during a child-friendly Stroop task (i.e., day-night task). Additionally, researchers aimed to assess whether the Stroop task, compared to a control task, was a significant physiological stressor.

Method: Fifteen preschool-age CWS and 22 preschool-age CWNS were asked to perform a day-night Stroop task in order to elicit psychophysiological reactivityindexed by electrodermal response (EDR) occurrence frequency and EDR amplitude. Physiological measurements were recorded during pretask baselines, performance of the day-night Stroop task, and performance of a speech-language control task.

Results: Findings based on EDR measures did not support the hypothesis that the child-friendly day-night Stroop task is an effective stressor as compared to a control task based on measures of physiological arousal in preschool-age children. The CWS and CWNS did not significantly differ in their EDR measures relative to the control task or Stroop task (p > .05). However, CWS, compared to CWNS, exhibited significantly greater EDR amplitudes during the control task baseline (p < .05) and the Stroop task baseline (p < .05).

Conclusion: Overall, these findings may suggest that a predisposition to heightened levels of sympathetic activity prior to tasks in preschool-age CWS is important to consider with regard to the nature of developmental stuttering.

Background: Having a stammer can have a significant effect on a child's social, emotional and educational development. With approximately 66,000 children in the UK having a stammer, there is a need to establish an adequate evidence base to inform clinical practice. We describe a feasibility trial to explore the effectiveness of a new therapy programme for children aged 8-14: Palin Stammering Therapy for School Children (Palin STSC(8-14)). Preliminary data from the Michael Palin Centre, where the programme was developed, indicate that Palin STSC(8-14) is effective in reducing stammering frequency and impact for children, with beneficial effects for parents too. We will investigate the feasibility of the methods required for a definitive randomised controlled trial to investigate the application of this therapy by NHS speech and language therapists (SLTs), compared with 'treatment as usual' (TAU), beyond the specialist context in which it was developed.

Methods: This is a two-arm feasibility cluster-randomised controlled trial of Palin STSC(8-14) with TAU control arm, and randomisation at the level of the SLT. Quantitative and qualitative data will be collected to examine the following: the recruitment and retention of therapists and families, the acceptability of the research processes and the therapeutic intervention and the appropriateness of the therapy outcome measures. Assessments will be completed by children and parents at baseline and 6 months later, including measures of stammering severity; the impact of child's stammering on both children and parents; child temperament, behaviour and peer relations, anxiety; quality of life; and economic outcomes. There will also be a qualitative process evaluation, including interviews with parents, children, SLTs and SLT managers to explore the acceptability of both the research and therapy methods. Treatment fidelity will be examined through analysis of therapy session records and recordings.

Discussion: The findings of this feasibility trial will inform the decision as to whether to progress to a full-scale randomised controlled trial to explore the effectiveness of Palin STSC(8-14) when compared to Treatment as Usual in NHS SLT services. There is a strong need for an evidence-based intervention for school age children who stammer.

Exogenous verbal response inhibition in adults who do and do not stutter - PSICOMOTOR

Introduction: Behavioral and questionnaire-based studies suggest that children who stutter (CWS) exhibit poorer response inhibition than children who do not stutter (CWNS). However, the behavioral findings in adults who stutter (AWS) are less unequivocal and mainly based on manual response inhibition. Further study is therefore needed, especially given the lack of studies on verbal response inhibition among these groups.

Methods: Thirteen AWS and 14 adults who do not stutter (AWNS) participated in a verbal stop signal task (SST) in which they were asked to read aloud six Chinese characters as fast as possible during the go-signal and ignore-signal trials and refrain from naming them during the stop-signal trials.

Results: The two groups showed a comparable response reaction time in the go-signal and ignore-signal trial conditions. Furthermore, there were no significant differences in terms of the stop-signal reaction time (SSRT) and accuracy. However, a significant positive correlation was found between SSRT and the frequency of stuttering in conversation but not in reading.

Conclusion: Current findings seem to provide additional support that exogenously triggered response inhibition among AWS does not differ from AWNS. The association between stuttering frequency and SSRT seems to suggest that individuals with more severe stuttering in conversational speech have reduced exogenous response inhibition. However, this finding needs to be further explored in future studies using different measures of stuttering severity.

Speech and language impairment is core in Koolen-de Vries syndrome (KdVS), yet only one study has examined this empirically. Here we define speech, language, and functional/adaptive behaviour in KdVS; while deeply characterising the medical/neurodevelopmental phenotype in the largest cohort to date. Speech, language, literacy, and social skills were assessed using standardised measures, alongside an in-depth health and medical questionnaire. 81 individuals with KdVS were recruited (35 female, mean age 9y 10mo), 56 of whom harboured the typical 500-650 kb 17q21.31 deletion. The core medical phenotype was intellectual disability (largely moderate), eye anomalies/vision disturbances, structural brain anomalies, dental problems, sleep disturbance, musculoskeletal abnormalities, and cardiac defects. Most were verbal (62/81, 76.5%), while minimally-verbal communicators used alternative and augmentative communication (AAC) successfully in spite of speech production delays. Speech was characterised by apraxia (39/61, 63.9%) and dysarthria (28/61, 45.9%) in verbal participants. Stuttering was described in 36/47 (76.6%) verbal participants and followed a unique trajectory of late onset and fluctuating presence. Receptive and expressive language abilities were commensurate with one another, but literacy skills remained a relative weakness. Social competence, successful behavioural/emotional control, and coping skills were areas of relative strength, while communication difficulties impacted daily living skills as an area of comparative difficulty. Notably, KdVS individuals make communication gains beyond childhood and should continue to access targeted therapies throughout development, including early AAC implementation, motor speech therapy, language/literacy intervention, as well as strategies implemented to successfully navigate activities of daily living that rely on effective communication.

Fostering Positive Stuttering Identities Using Stutter-Affirming Therapy - TERAPIA

Lang Speech Hear Serv Sch. 2022 Dec 29;1-21. Online ahead of print.


Christopher Dominick Constantino

Florida State University, Tallahassee.


Purpose: School-age children and adolescents frequently have difficulty developing positive identities around their stuttering. Many students experience both physical and social consequences from stuttering. The great lengths that speakers go to try to hide their stuttering and to speak fluently increase their difficulty. As long as school-age children who stutter try to identify as fluent speakers, they will have difficulty lessening the negative impact of stuttering on their lives. Fortunately, many people who stutter also report positive stuttering experiences. Speech-language pathologists can use these positive experiences to help school-age children grow more comfortable with stuttering. They can also help school-age children reduce some of the speaking effort and social stigma that leads them to try to conceal their stuttering in the first place. To accomplish both these goals, I propose a stutter-affirming therapy.

Method: This clinical focus article summarizes previous research about identity development in stuttering. I discuss a therapy approach I call stutter-affirming therapy. In elucidating this approach, I discuss practical ways that speech-language pathologists can use to help school-age children develop positive stuttering identities through easier speaking and stuttering. I ground these examples in a case study of a 12-year-old boy who stutters.

Discussion: stutter-affirming therapy focuses on conditioning the speaker's reaction to stuttering in ways that move toward and embrace stuttering (stutterphilic reactions) rather than in ways that move away from and reject stuttering (stutterphobic reactions). Speech-language pathologists can help school-age children who stutter foster positive stuttering identities using the three priorities of stutter-affirming therapy. First, reject fluency by reducing stutterphobic and increasing stutterphilic reactions to stuttering. Second, value stuttering by discovering what speakers gain from it. Third, create an environment in which it is easier to stutter through education, advocacy, disclosure, and voluntary stuttering.

Purpose: The purpose of this pilot study was to determine the effectiveness and acceptability of an initial module (1.1; active listening skills) of the Simulated Training in Evidence-Based Practice for Stuttering (STEPS) program, a theory-driven, multimodule, content and learning platform designed to advance knowledge and skills in working with culturally and linguistically diverse persons who stutter of all ages.

Method: Fifteen preservice speech-language pathologists (SLPs) were randomly assigned to complete either the STEPS 1.1 module or a control module. In both conditions, all participants engaged in pre- and post-clinical interviews with a standardized patient portraying a parent of a child who stutters. Prior to participation, all participants provided self-ratings on the Jefferson Scale of Physician Empathy-Health Profession Student. Post participation, trained observers rated all participants' active listening behaviors using the Active Listening Observation Scale-Modified. Post participation, the STEPS 1.1 participants also completed an intervention acceptability questionnaire.

Results: No differences between groups were found in self-perceived clinical empathy prior to participation. Participants who completed the STEPS 1.1 condition utilized paraphrasing and client-directed eye gaze significantly more frequently at posttest than at pretest and significantly more than the control group at posttest. Quantitative and qualitative responses from the participants who completed STEPS 1.1 indicated high acceptability of its content, structure, duration, and perceived impact.

Conclusion: Preliminary data from the present pilot study support use of the STEPS 1.1 module to improve preservice SLPs' use of skills that have been shown to predict perceived clinical empathy and increase assessment and treatment effectiveness.

Purpose: Prior research has suggested that people who stutter exhibit differences in some working memory tasks, particularly when more phonologically complex stimuli are used. This study aimed to further specify working memory differences in adults who stutter by not only accounting for linguistic demands of the stimuli but also individual differences in attentional control and experimental influences, such as concomitant processing requirements.

Method: This study included 40 adults who stutter and 42 adults who do not stutter who completed the Attention Network Test (ANT; Fan et al., 2002) and three complex span working memory tasks: the Operation Span (OSPAN), Rotation Span, and Symmetry Span (Draheim et al., 2018; Foster et al., 2015; Unsworth et al., 2005, 2009). All complex span tasks were dual-tasks and varied in linguistic content in task stimuli.

Results: Working memory capacities demonstrated by adults who stutter paralleled the hierarchy of linguistic content across the three complex span tasks, with statistically significant between-group differences in working memory capacity apparent in the task with the highest linguistic demand (i.e., OSPAN). Individual differences in attentional control in adults who stutter also significantly predicted working memory capacity on the OSPAN.

Discussion: Findings from this study extend existing working memory research in stuttering by showing that: (1) significant working memory differences are present between adults who stutter and adults who do not stutter even using relatively simple linguistic stimuli in dual-task working memory conditions; (2) adults who stutter with stronger executive control of attention demonstrate working memory capacity more comparable to adults who do not stutter on the OSPAN compared to adults who stutter with lower executive control of attention.

Introduction: In the early 20th century a link between infection and speech disfluency was discussed. Recent reports indicate that PANS (Pediatric Acute-onset Neuropsychiatric Syndrome), and PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections) may be associated with a high incidence of speech disfluency. The present study specifically investigates disfluency and other speech symptoms following onset of PANS and PANDAS. Prevalence of previously reported speech related symptoms vocal tics, selective mutism and "baby talk" is included. The present study also aims to explore possible changes in articulation and intelligibility, distress due to speech impairment, and effect of PANS or PANDAS medication on speech symptoms.

Methods: A questionnaire was distributed to caregivers of children with diagnosed or suspected PANS or PANDAS. In total 55 individuals in Sweden were included.

Results: Onset of speech disfluency in association with PANS or PANDAS was reported by 54.5% of the caregivers. Most frequent disfluency symptoms were higher speech rate, superfluous verbal behavior, verbal blocks and associated motor symptomsPrevious findings of vocal tics, baby talk and mutistic behavior are supported. The present study also exposed previously unreported symptoms such as impaired articulation, reduced intelligibility, reduced speech production and language impairment. Eleven caregivers reported that medical treatment had a positive effect on speech fluency.

Conclusions: A connection between PANS and PANDAS and speech disfluency is supported, and a possible link between infection and disfluency is reactualized. Reported disfluency shares several characteristics with stuttering and cluttering, but the caregivers did not consistently associate it with stuttering. The present study also sheds new light on how symptoms of "baby talk", selective mutism and vocal tics might be viewed in this population. In all, the results indicate a substantial impact on speech fluency, speech and language in affected children, reducing quality of life.

Lurie Children's Hospital of Chicago, Chicago, Illinois, USA; Feinberg School of Medicine of Northwestern University, Chicago, Illinois, USA.


Objective: To evaluate the use of telemedicine as a collaboration tool between a pediatrician and subspecialists looking to address challenges, such as the lack of health care specialists, which are present in the Dominican Republic.
Study design: During this 6-year study, 65 patients were evaluated by a medical team consisting of a local pediatrician and 17 subspecialists from a leading academic medical center in the Unites States. Patient's age ranged from 2 months to 16 years of age (mean 8 years old). The most common reasons for referral were masses or malignancies, vascular malformations, urogenital anomalies, stuttering, and cochlear implant programming.

Results: A total of 39 out of 65 cases (60%) carried an initial diagnosis. Of the 65 cases, a change in medical management occurred in 92.31% of cases (60 cases). There was no change in medical diagnosis or treatment in 5 of 65 cases (8%).

Conclusion: This protocol exhibited high patient satisfaction with the technology and platform and direct patient savings from transportation costs. It also demonstrated the importance of thorough diagnosis in providing appropriate treatment and solutions. Telemedicine use in comparable practices should be studied further to aid in the development of policies for the diagnosis and management of chronic illnesses that require referrals to subspecialists.

Sue O'Brian et al

University of Technology Sydney, NSW, Australia; University of Sydney, NSW, Australia; Bristol Speech and Language Therapy Research Unit, North Bristol NHS Trust, Bristol, UK; Bond University, QLD, Australia.


Background: Early intervention is essential healthcare for stuttering, and the translation of research findings to community settings is a potential roadblock to it.

Aims: This study was designed to replicate and extend the Lidcombe Program community translation findings of O'Brian et al. (2013) but with larger participant numbers, incorporating clinicians (speech pathologists/ speech and language therapists) and their clients from Australia and England.

Methods & procedures: Participants were 51 clinicians working in public and private clinics across Australia (n = 36) and England (n = 15), and 121 of their young stuttering clients and their families. Outcome measures were percentage of syllables stuttered (%SS), parent severity ratings at 9 months post-recruitment, number of clinic visits to complete Stage 1 of the Lidcombe Program, and therapist drift.

Outcomes & results: Community clinicians in both countries achieved similar outcomes to those from randomized controlled trials. Therapist drift emerged as an issue with community translation. Speech and language therapists in England attained outcomes 1.0%SS above the speech pathologists in Australia, although their scores were within the range attained in randomized trials.

Conclusions & implications: Community clinicians from Australia and England can attain Lidcombe Program outcome benchmarks established in randomized trials. This finding is reassuring in light of the controlled conditions in clinical trials of the Lidcombe Program compared with its conduct in community practice. The long-term impact of therapist drift in community clinical practice with the Lidcombe Program has yet to be determined.

Aim: This study aimed to determine the effects of various sociodemographic variables and experiences, unhelpful beliefs about stuttering, and perceived social support on psychological well-being in stuttering adults.

Methods: Forty-five stuttering adults were included in our study, and sociodemographic data were collected using a stuttering experiences information form, the Unhelpful Thoughts and Beliefs About Stuttering (UTBAS)-6 scale, the perceived social support scale, and the Warwick-Edinburgh Mental Well-being Scale.

Results: It was determined that the total score of the UTBAS scale, the high scores on the fear of negative evaluation, avoidance, self-doubt and insecurity, and the hopelessness subscales, and the low scores of the perceived social support scale were correlated with lower psychological well-being results in stuttering individuals.

Conclusions: To support the mental well-being of individuals with stuttering, we believe it would be beneficial to provide mental assessment and supportive approaches, raise awareness to eliminate prejudice and stigmatizing attitudes toward individuals with stuttering in the family and wider society, and develop social support systems, alongside speech therapy.

A myoclonic epilepsy with ragged-red fibers (MERRF) patient who carried the m.8344A>G variant in the homoplasmic form manifested a milder phenotype than his sister who carried the same variant in the heteroplasmic form, which has not yet been reported. The 27-year-old male, with an uneventful history, presented at age 19 with fatigue and persistent tremor in both handsWhen he talked for a long time, his speech would slow down, and he would stutter. Although electroencephalography showed spike-wave complexes in both occipital projections with generalization, no anti-seizure drugs were given. At age 20, the patient suffered a fall due to muscle weakness. From age 21, generalized myocloni occurred. Because the sister had been diagnosed with MERRF-plus syndrome, the patient underwent genetic testing, which revealed the m.8344A>G variant in homoplasmy. L-carnitine was started. At age 27, the patient experienced a first "syncope" after a long walk, which subsequently recurred up to 2-3 times per day. EEG showed low-amplitude spikes, slow-spike waves at the posterior vertex, and generalized slow-spike waves. Clonazepam was recommended but declined by the patient. In conclusion, the m.8344A>G variant may manifest milder and with a later onset in the homoplasmic as compared to the heteroplasmic form. Further, the homoplasmy of the m.8344A>G variant appears to be more beneficial than harmful.

Materials and methods: A total of 498 mouth-breathers, both male and female, aged 9-17 years, were screened for allergic rhinitis (AR), adenoid hypertrophy (AH), and/or functional mouth breathing (FM). The subjects were assessed by a team that included an otorhinolaryngologist, an allergologist, an orthodontist, and a speech pathologist.

Results: MB was associated with AR, AH, FM, and orofacial myofunctional disorders (OMD). AR was the most common etiology, followed by FM. Further, 81.7% of the children had speech disorders such as speech sound problems, fluency disorders, and voice disorders. A statistically significant association was found between etiology, OMD, and speech alterations. Males had a statistically highly significant frequency of speech abnormalities than females. Frontal lisp was found in 36.1%, followed by stuttering (19.2%). In 10.6% of the children, two or more speech impediments occurred simultaneously. There was also a statistically significant association between various speech abnormalities and malocclusion.

Conclusion: The findings of the study suggested that articulation disorders were frequently associated with MB children. It emphasizes the necessity of monitoring MB children through a multidisciplinary approach to prevent the adverse effects of MB and improve the overall development of individuals.

A key goal of cognitive neuroscience is to better understand how dynamic brain activity relates to behavior. Such dynamics, in terms of spatial and temporal patterns of brain activity, are directly measured with neurophysiological methods such as EEG, but can also be indirectly expressed by the body. Autonomic nervous system activity is the best-known example, but, muscles in the eyes and face can also index brain activity. Mostly parallel lines of artificial intelligence research show that EEG and facial muscles both encode information about emotion, pain, attention, and social interactions, among other topics. In this study, we examined adults who stutter (AWS) to understand the relations between dynamic brain and facial muscle activity and predictions about future behavior (fluent or stuttered speech). AWS can provide insight into brain-behavior dynamics because they naturally fluctuate between episodes of fluent and stuttered speech behavior. We focused on the period when speech preparation occurs, and used EEG and facial muscle activity measured from video to predict whether the upcoming speech would be fluent or stuttered. An explainable self-supervised multimodal architecture learned the temporal dynamics of both EEG and facial muscle movements during speech preparation in AWS, and predicted fluent or stuttered speech at 80.8% accuracy (chance=50%). Specific EEG and facial muscle signals distinguished fluent and stuttered trials, and systematically varied from early to late speech preparation time periods. The self-supervised architecture successfully identified multimodal activity that predicted upcoming behavior on a trial-by-trial basis. This approach could be applied to understanding the neural mechanisms driving variable behavior and symptoms in a wide range of neurological and psychiatric disorders. The combination of direct measures of neural activity and simple video data may be applied to developing technologies that estimate brain state from subtle bodily signals.

Stuttering is a puzzling disorder which involves voluntary repetition, prolongation along with blocking and other interruptions to the flow of speech. Stuttering impacts on quality of life of individuals with difficulties in overall social behavior and performance. The present study focuses on perception of stuttering by individual with stuttering and their experiences toward their stuttering among family and society. The present study was carried out in two phases. Phase 1 included the development of questionnaire and phase 2 incorporated the administration of questionnaire and analysis of the results. Total of 20 participants (16 males and 4 females) between the age ranges of 15-50 years (SD = 8.33) were included in the study. The results of present study consisted of perception of the individual with stuttering, their family members and other people regarding the probable cause, effects and treatment of stuttering. The causes were than categorized into psychological, superstitious, genetic, physiological and unknown. Likewise the treatment was categorized into speech therapy, medical treatment, self management strategies, superstitious beliefs and unknown. Many of the participants, their family members and other people had inappropriate, irrational and superstitious believes about the cause and treatment of stuttering due to which they faced many difficulties in their life. Hence from this study we conclude that there is requirement of awareness regarding the etiologies of stuttering and its consequences in hazarding the quality of life. It was also observed the urgent need of awareness regarding the speech therapy and its beneficial outcome in enhancing the fluency of individuals with stuttering, therefore, avoiding the consequence of the condition in their life.

Phenytoin (PHT) was first synthesized as a barbiturate derivative and was approved in 1953 by the Food and Drug Administration. This work aimed to review the pathophysiology, epidemiology, clinical presentation, and treatment of PHT-associated movement disorders (MDs). Studies were searched in relevant databases (ScienceDirect, Google Scholar, Excerpta Medica, Latin American and Caribbean Health Sciences Literature, Medline, and Scientific Electronic Library Online) and were selected by two reviewers irrespective of language between 1963 and 2021. Papers of PHT-induced ataxia alone or tremor were excluded. In total, 127 reports with 219 individuals who developed MDs associated with PHT were encountered. MDs found: 126 dyskinesias, 49 myoclonus, 19 dystonia, 14 parkinsonism, 6 tics, 3 stuttering, and 2 restless legs syndrome. The mean age was 35 years (standard deviation [SD]: 23.5) and the predominant sex was male (53.4%). The mean PHT dose when the MD took place was 370.4 mg (SD: 117.5). A serum PHT concentration was reported in 103 cases, ranging from 4 to 110 μg/mL (median: 27.7 μg/mL). No significant relationship was found between PHT dose and age or PHT level. The mean onset time of PHT-associated MD was 23.4 months (SD: 4.4). The mean recovery time after MD management was 3.7 weeks (SD: 1.1). Regarding management, the most common form was PHT withdrawal in 90.4%. 86.3% of the individuals recovered fully. PHT-induced MD was extensively reported in the literature. Only general terms were used in the majority of the reports. The mechanisms underlying the adverse events caused by PHT probably depend on the presence of predisposing factors.

The presented first-of-its-kind study effectively identifies and visualizes the second-by-second pattern differences in the physiological arousal of preschool-age children who do stutter (CWS) and who do not stutter (CWNS) while speaking perceptually fluently in two challenging conditions: speaking in stressful situations and narration. The first condition may affect children's speech due to high arousal; the latter introduces linguistic, cognitive, and communicative demands on speakers. We collected physiological parameters data from 70 children in the two target conditions. First, we adopt a novel modality-wise multiple-instance-learning (MI-MIL) approach to classify CWS vs. CWNS in different conditions effectively. The evaluation of this classifier addresses four critical research questions that align with state-of-the-art speech science studies' interests. Later, we leverage SHAP classifier interpretations to visualize the salient, fine-grain, and temporal physiological parameters unique to CWS at the population/group-level and personalized-level. While group-level identification of distinct patterns would enhance our understanding of stuttering etiology and development, the personalized-level identification would enable remote, continuous, and real-time assessment of stuttering children's physiological arousal, which may lead to personalized, just-in-time interventions, resulting in an improvement in speech fluency. The presented MI-MIL approach is novel, generalizable to different domains, and real-time executable. Finally, comprehensive evaluations are done on multiple datasets, presented framework, and several baselines that identified notable insights on CWSs' physiological arousal during speech production.

Purpose: This study aims to: (a) measure public attitudes toward stuttering in Malaysia using the Public Opinion Survey of Human Attitudes-Stuttering [POSHA-S], (b) determine how reported attitudes and knowledge related to stuttering compare to existing data, and (c) determine whether there are differences between groups for identified variables.

Method: A total of 250 adults (mean age = 29 years; range = 19-60 years) completed the POSHA-S in English. We compared this sample's attitudes toward stuttering to POSHA-S data from other global samples. General linear modeling examined differences in overall stuttering score, beliefs, and self reaction subscores for demographic variables such as age, gender, marital status, parenting, education, employment status, prior exposure to a person who stutters, multilingual, race, and religion.

Results: The Malaysian participants' overall stuttering score and the beliefs and self reactions subscores were all considerably lower (i.e., less positive) than the other samples around the world from the POSHA-S database median values. Being male, receiving a higher education, and knowing someone who stutters were linked to having more positive self reactions, but none of those factors was linked to positive or negative beliefs. Those who had previously been exposed to stuttering scored significantly higher than those who had not.

Conclusion: Malaysians may have less positive attitudes toward stuttering than Westerners. More needs to be done to make society more accepting of people who stutter. Future research should aim to find ways to educate and to raise public awareness about stuttering.

Objective: The present study aimed at measuring the level of public speaking anxiety (PSA) among medical residents in Riyadh, in addition to identifying the factors influencing public speaking anxiety from the perspective of the medical residents.

Method: A cross-sectional survey was conducted over a sample of 203 medical residents in Riyadh. The study adopted the questionnaire as a data collection tool. The questionnaire consisted of a demographic data part, PSA scale (17 items) and a third part concerned with the factors influencing public speaking anxiety among medical residents.

Results: The results of the study revealed that medical residents in Riyadh had a low level of public speaking anxiety (47.3±11.32). The participants had a low PSA score on all scale domain; cognitive (23.28±5.43), behavioral (10.45±4.16), and physiological (13.54±3.44). Moreover, the findings of the study showed that stuttering (91.1%), negative perceptions of individuals' own voice (77.8%), and language barriers (76.8%) were the main factors influencing the public speaking anxiety among medical residents. Finally, we found through linear regression analysis that PSA is not significantly predicted by participants' living region, marital Status, gender, residency level, type of pre-college school, age or being previously diagnosed by a mental health issue.

Conclusion: There is a low level of public speaking anxiety among medical residents in Riyadh. In addition, the study concluded that stuttering, negative perceptions about voice and language barriers are negatively influencing the public speaking anxiety among medical residents in Riyadh.

Background: Stuttering is characterized by dysfluency and difficulty in speech production. Previous research has found abnormalities in the neural function of various brain areas during speech production tasks. However, the cognitive neural mechanism of stuttering has still not been fully determined.

Method: Activation likelihood estimation analysis was performed to provide neural imaging evidence on neural bases by reanalyzing published studies.

Results: Our analysis revealed overactivation in the bilateral posterior superior temporal gyrus, inferior frontal gyrus, medial frontal gyrus, precentral gyrus, postcentral gyrus, basal ganglia, and cerebellum, and deactivation in the anterior superior temporal gyrus and middle temporal gyrus among the stutterers. The overactivated regions might indicate a greater demand in feedforward planning in speech production, while the deactivated regions might indicate dysfunction in the auditory feedback system among stutterers.

Conclusions: Our findings provide updated and direct evidence on the multi-level impairment (feedforward and feedback systems) of stutterers during speech production and show that the corresponding neural bases were differentiated.

The Lidcombe Program is a well-established and efficacious treatment for early stuttering, but little is currently known about its mechanisms of action. The present report explores the possibility that inter-turn speaker latency might be associated with such mechanisms of action. Inter-turn speaker latency was measured in audio recordings of children, parents, and clinicians conversing, taken during Lidcombe Program treatment consultations. Five clinicians reduced their inter-turn speaker latencies during clinical consultations when they were speaking to children, in comparison with when they were speaking to parents. It is possible that inter-turn speaker latency is associated with the Lidcombe Program treatment process vicariously, and this possibility requires further research.

Purpose: Self-disclosure describes the act of revealing personal information to another person. To date, researchers in the area of stuttering have primarily demonstrated the utility of self-disclosure through analysis of listener perceptions. This study explores the utility of informative self-disclosure use from the perspectives of adults who stutter with experience using this strategy over time and across contexts.

Method: Twelve adults who stutter discussed their self-disclosure experiences in semistructured interviews. Interview transcripts were analyzed using interpretative phenomenological analysis to produce themes reflecting the most salient aspects of self-disclosure experiences. Credibility was achieved through bracketing, investigator triangulation, and member checking.

Results: Four superordinate themes reflecting experiences shared by all 12 participants were generated. Each superordinate theme contained two to three corresponding subthemes. The superordinate themes included cognitive relief, self-empowerment, social connection, and personalization. These findings reflect the positive impact of informative self-disclosure use on communication and quality of life.

Conclusions: Adults who stutter perceive informative self-disclosure to be an effective strategy that provides various benefits to the speakerin addition to facilitating positive listener perceptionsClinicians should encourage clients to self-disclose in an informative and personalized manner, provide opportunities for practice, and support clients in determining when and where it is most beneficial for them to implement this strategy.

Background: While there is sufficient evidence that children and adolescents who stutter reported more impaired sleep compared to children and adolescents who did not stutter, findings among adults who stutter (AWS) were scarce. Furthermore, stuttering is associated with issues related to verbal communication in a social context. As such, it was conceivable that AWS reported higher scores for social anxiety, compared to adults who do not stutter (AWNS). In the present study, we tested whether AWS reported higher sleep complaints compared to AWNS. We further tested whether scores for social anxiety and stuttering independently predicted sleep disturbances.

Methods: A total of 110 AWS (mean age; 28.25 years, 27.30% females) and 162 AWNS (mean age; 29.40 years, 51.20% females) completed a series of self-rating questionnaires covering sociodemographic information, sleep disturbances and social anxiety. Adults with stuttering further completed a questionnaire on stuttering.

Results: Compared to AWNS, AWS reported a shorter sleep duration, a lower sleep efficiency, higher scores for drug use in terms of sleep-promoting medications (significant p-values and medium effect sizes), and an overall higher PSQI score (significant p-values and large effect size), when controlling for age and social anxiety. Next, while p-values were always significant for subjective sleep quality, sleep disturbances, and daytime functioning, when controlling for age and social anxiety, their effect sizes were trivial or small. For sleep latency, the p-value was not significant and the effect size was trivial. Among AWS, higher scores for stuttering and older age, but not social anxiety, predicted higher sleep disturbances. The association between higher sleep disturbances and higher stuttering severity was greatest among those AWS with highest scores for social anxiety. Conclusions: When compared to AWNS, AWS self-reported higher sleep disturbances, which were associated with older age, and higher scores for stuttering severity, but not with social anxiety. Adults who stutter might be routinely asked for their sleep quality.

AP-4-associated hereditary spastic paraplegia (HSP), also known as AP-4 deficiency syndrome, is a genetically diverse group of neurologic disorders defined by complex spastic paraplegia. Different forms of AP-4-associated HSP are classified by chromosomal locus or causative gene. Spastic paraplegia 51 (SPG51) is a neurodevelopmental condition that is caused by autosomal recessive mutations in the adaptor protein complex 4 complex subunit 1 (AP4E1) gene. Further, previous studies described an autosomal dominant mutation in the AP4E1 gene has also been linked to persistent stuttering. Here, we describe a patient from a consanguineous marriage who manifested severe intellectual disability (ID), absent speech, microcephaly, seizure, and movement disorders. Exome sequencing identified a novel homozygous frame-shift variant (NM_007347.5:c.3214_3215del, p.Leu1072AlafsTer10) in the AP4E1 gene, which was confirmed by Sanger sequencing. In this study, we also reviewed the phenotype of the former cases. Our findings added to the knowledge of little-studied homozygous AP4E1 mutation

Speech and Language Errors during Awake Brain Surgery and Postoperative Language Outcome in Glioma Patients: A Systematic Review - OUTRAS ÁREAS

Review Cancers (Basel). 2022 Nov 7;14(21):5466.

Awake craniotomy with direct electrical stimulation (DES) is the standard treatment for patients with gliomas in eloquent areas. Even though language is monitored carefully during surgery, many patients suffer from postoperative aphasia, with negative effects on their quality of life. Some perioperative factors are reported to influence postoperative language outcome. However, the influence of different intraoperative speech and language errors on language outcome is not clear. Therefore, we investigate this relation. A systematic search was performed in which 81 studies were included, reporting speech and language errors during awake craniotomy with DES and postoperative language outcomes in adult glioma patients up until 6 July 2020. The frequencies of intraoperative errors and language status were calculated. Binary logistic regressions were performed. Preoperative language deficits were a significant predictor for postoperative acute (OR = 3.42, p &lt; 0.001) and short-term (OR = 1.95, p = 0.007) language deficitsIntraoperative anomia (OR = 2.09, p = 0.015) and intraoperative production errors (e.g., dysarthria or stuttering; OR = 2.06, p = 0.016) were significant predictors for postoperative acute language deficits. Postoperatively, the language deficits that occurred most often were production deficits and spontaneous speech deficits. To conclude, during surgery, intraoperative anomia and production errors should carry particular weight during decision-making concerning the optimal onco-functional balance for a given patient, and spontaneous speech should be monitored. Further prognostic research could facilitate intraoperative decision-making, leading to fewer or less severe postoperative language deficits and improvement of quality of life.

Stuttering is a poorly understood and highly stigmatizing disorder. The author describes his personal experiences with childhood stuttering, as they are stirred by listening to President Biden speak the State of the Union speech. As a stutterer, he can hear and understand the pauses in President Biden’s speech and appreciate the effort the President makes as a public speaker and the control he uses to avoid stuttering.

Purpose: The aims of this study were to investigate the occurrence of stuttering behavior across time and to evaluate the relationship between stuttering behavior and language ability in children with Down syndrome.

Method: A national age cohort of Norwegian first graders with Down syndrome (N = 75) participated in the study. Speech samples from a story-retelling task and a picture book dialogue as well as standardized measures of vocabulary, grammar, and nonverbal mental ability were collected at two time points approximately 5 months apart. Stuttering behavior was evaluated through counting stuttering-like disfluencies and stuttering severity ratings. The relationship between stuttering behavior and language ability was investigated through hierarchical regression analysis.

Results: The participants had stuttering severity ratings ranging from no stuttering behavior to severe and displayed all types of stuttering-like disfluencies. There were significant relationships between stuttering behavior and language ability at the first time point, whereas the relationships were not significant at the second time point. The stuttering severity ratings were significantly predicted by language ability across time, whereas the frequency of stuttering-like disfluencies was not.

Conclusions: The occurrence of stuttering behavior was high across the measures and time points; however, the relationship between stuttering behavior and language ability varied across these variables. Thus, the nature of the relationship does not seem to follow a strict pattern that can be generalized to all children across time.

Background: Information about genetic influence is useful to when counselling parents or caregivers who have infants and children at risk for stuttering. Yet, the most comprehensive family aggregate database to inform that counselling is nearly four decades old (Andrews et al., 1983). Consequently, the present study was designed to provide a contemporary exploration of the relationship between stuttering and family history.

Methods: Data were sourced from the Australian Stuttering Research Centre, comprising 739 participants who presented for assessment, treatment, or investigation of stuttering. Reported family history data were acquired from pedigrees collected during assessment. We sought to establish the relation of the following variables to family history of stuttering: incidence, proband sex, parent sex, stuttering severity, age, reported age of stuttering onset, and impact of stuttering. Data were analysed with chi-square tests for independence, logistic and linear regression models.

Results: Results were broadly consistent with existing data, but the following findings were novelMales and females who stutter have the same increased odds of having a father who stutters relative to a mother who stutters. Males had later stuttering onset than females, with genetic involvement in this effect. There was a greater impact of stuttering for females than males with a family history of stuttering.

Conclusion: These findings have clinical applications. Speech-language pathologists may have infant or child clients known to them who are at risk of beginning to stutter. Information from the present study can be applied to counselling parents or caregivers of such children about stuttering and family history.

Purpose: Speech-language pathologists are influential in shaping identity development for individuals who stutter, particularly as it relates to communication. This study investigated the experiences of lesbian, gay, and bisexual individuals who stutter to learn more about how multiple marginalized identities affect their psychosocial experiences.

Method: Semi-structured interviews were conducted with seven individuals who stutter with lesbian, gay, and bisexual identities. Participants ranged in age from 22 to 60 years. Data were analyzed for themes and categories by using interpretive phenomenological analysis.

Results: Four primary themes were identified: (a) the importance of visibility and shared social identity connections for affirmation; (b) effects of oppressive social expectations on identity; (c) intersectionality of stuttering, gay, lesbian, and bisexual identities; and (d) effects of not being affirmed for identity.

Discussion: Results are discussed in the context of identity affirmation and intersectionality. Through an understanding of identity formation and psychosocial experiences of lesbian, gay, and bisexual individuals who stutter, speech-language pathologists can use identity-affirmative practices to support individuals who stutter and mitigate stigmatizing experiences. Implications focus on suggestions for the provision of identity-affirming speech-language pathology practices for students who stutter.

Data was analysed using SPSS 23.

Results: Of the 78 subjects, 66(84.6 %) were males and 12 (15.4 %) were females. There were 21(27%) subjects aged 16-19 years and 57(73%) with age range of 20-30 years. The overall mean age was 21.96±3.89 years. Mean age of onset was 4.59±1.29 years, while gradual onset and progressive stuttering was reported by 74(94.9 %). The Bilingual users 49(63%) reported to have frequent stuttering. Among the 43(55.1%) who had received treatment, 30(38%) received speech therapy and 26(33.3%) reported dissatisfaction. Stuttering severity and social anxiety were significantly positively correlated with all domains of impact of stuttering (p<0.05). Age, and duration were negatively correlated with day-to-day communication (p<0.05) and previous speech treatment showed negative association with impact on general knowledge about stuttering (p<0.05). Avoidance coping strategy had a significant relationship with all domains of impact (p<0.05).

Conclusions: Severity of stuttering and social anxiety were found to have repercussions on people who stuttered, while avoidance coping was practised more to deal with the negative impact on reactions toward stuttering and quality of life.

Stuttering Severity Judgments by Speech-Language Pathologists of Bilingual Children Who Do and Do Not Stutter - LINGUAGEM

Folia Phoniatr Logop. 2022 Dec 5. Online ahead of print.


Selma Saad Merouwe, Raymond Bertram, Sami Richa, Kurt Eggers


Introduction: Recent studies conducted with bilingual populations have shown that bilingual children who do not stutter (CWNS) are often less fluent than their monolingual counterparts, which seems to affect the accuracy with which speech-language pathologists (SLPs) identify stuttering in bilinguals. That is, misdiagnosis appears frequently in bilingual children, and is more likely to occur with bilingual CWNS (false positives) than bilingual CWS (false negatives).

Methods: The goal of the current study was to gain insight in the extent of this misdiagnosis. Speech samples of 6 Lebanese bilingual CWNS and 2 CWS were rated by Lebanese SLPs in an audio-only and audiovisual presentation mode. SLPs had to identify each child as stuttering or not and subsequently rate on a 6-point scale the stuttering severity for each child. SLPs also provided background information by means of a questionnaire.

Results: The results showed that stuttering severity ratings (1) were on average significantly higher for CWS than for CWNS, (2) were for each CWS higher than for all but one of the CWNS, (3) varied significantly among the CWNS but not the CWS, (4) were not affected by the presentation mode, and (5) correlated positively with the percentage of stuttering-like disfluencies (SLD) and the mean number of iterations, but not with the percentage of other disfluencies (OD).

Conclusion: Misdiagnosed bilingual CWNS are perceived by the SLPs as having a mild stutter, primarily based on the frequency of their disfluencies, but can be occasionally rated at par with CWS. Further research differentiating the disfluent speech of bilingual children who do and do not stutter is needed to reach a more adequate diagnosis of stuttering.

Stuttering is a common neurodevelopment speech disorder that negatively affects the socio-psychological dimensions of people with disability. It displays many attributes of a complex genetic trait, and a few genetic loci have been identified through linkage studies. Stuttering is highly variable regarding its phenotypes and molecular etiology. However, all stutters have some common features, including blocks in speech, prolongation, and repetition of sounds, syllables, and words. The involuntary actions associated with stuttering often involve increased eye blinking, tremors of the lips or jaws, head jerks, clenched fists, perspiration, and cardiovascular changes. In the present study, we recruited a consanguineous Pakistani family showing an autosomal recessive mode of inheritance. The exome sequencing identified a homozygous splice site variant in ARMC3 (Armadillo Repeat Containing 3) in a consanguineous Pashtun family of Pakistani origin as the underlying genetic cause of non-syndromic stuttering. The homozygous splice site variant (NM_173081.5:c.916 + 1G &gt; A) segregated with the stuttering phenotype in this family. The splice change leading to the skipping of exon-8 is a loss of function (LoF) variant, which is predicted to undergo NMD (Nonsense mediated decay). Here, we report ARMC3 as a novel candidate gene causing the stuttering phenotype. ARMC3 may lead to neurodevelopmental disorders, including stuttering in humans.

Purpose: The purpose of the current study was to document the pros and cons that adults who stutter may consider when deciding to change how they live with stuttering.

Methods: Semi-structured interviews were conducted with 11 adults who stutter and 12 speech-language pathologists who specialize in stuttering therapy. Participants were asked to identify and discuss the advantages and disadvantages of making a change to how they live with stuttering. Reflexive thematic analysis was used to generate multilevel themes.

Results: Meaningful units were extracted from interview transcripts to develop 37 discrete pros and 15 discrete cons. The pros of change clustered into five organizing themes: enriching one's social relationships, feeling better in social interactions, developing a healthier sense of self, gaining autonomy, and communicating easier. The cons of change clustered into three organizing themes: experiencing discomfort, expending resources, and recognizing that some things may not change.

Conclusion: This study documented why adults who stutter may or may not seek change. Identifying the pros and cons of behavior change is an important step in understanding why some clients who stutter are ambivalent about, or resistant to, the therapeutic process.

The Impact of Self-Disclosure and Strategies for Communication Competence on Professors' Perceptions and Evaluations of Students Who Do and Do Not Stutter - SOCIAL

J Speech Lang Hear Res. 2022 Aug 30;1-15. Online ahead of print.

Purpose: The purpose of this study was to examine the impact of self-disclosure and strategies for communication competence on perceptual ratings and performance evaluations of undergraduate students who do and do not stutter by professors who require oral presentations.

Method: Two hundred thirty-eight college instructors who require oral presentations in their classes participated in this study. Each participant viewed one video of six possible randomized conditions varying according to the presence and disclosure of stuttering (i.e., fluent, stuttering, stuttering + disclosure) and level of communication competence (i.e., high vs. low). Participants evaluated public speaking performance against a standardized rubric and rated the student along 16 personality traits.

Results: Results of separate 2 × 3 analyses of variance revealed that professors perceived a student who disclosed stuttering, compared to the identical video without disclosure, more positively overall. Significant interactions between fluency (i.e., presence vs. absence of stuttering vs. disclosure of stuttering) and communication competence (i.e., high vs. low) were found for overall performance evaluation scores. The video during which the student disclosed stuttering and presented with low communication competence was given a higher score than the identical video without disclosure.

Conclusions: Professors respond positively to both strategies for high communication competence and self-disclosure. High communication competence behaviors mitigate positive feedback bias. Disclosure results in improved positive perceptions across levels of communication competence. For students presenting with low communication competence, disclosure may improve evaluation of performance in oral presentations. The greatest perceptual and evaluative benefits were achieved with the combination of the two strategies.

There has been increasing interest over the past decade with regard to the health and wellbeing implications of time spent outdoors in nature for children. Universal systematic reviews of evidence report benefits to physical health, social-emotional mental health and wellbeing, cognition and academic learning. Internationally, there is indicative evidence to suggest outdoor engagement with nature may also impact children's language and communication skills, skills that are critical to development, education, social relationships and life opportunities. Yet, at present such evidence has not been synthesised. Despite evidence for the benefits of the outdoors, the amount of time children are spending outdoors is in rapid decline, and has been further exacerbated by the COVID-19 pandemic. Alongside this are increasing numbers of children starting primary education with significant speech, language and communication needs (SLCN) which remain persistent over time. With established wide-reaching benefits of nature to children's physical and mental health and psychological development, there is a need to further explore the more specific impacts of the natural environment on children's language, communication and social skills, which could provide a unique opportunity to consider nature as a universal public health intervention for SLCN. The current review will aim to synthesise existing qualitative and quantitative evidence of the impact of time spent in natural outdoor spaces on the language, communication and social skills of 2-11-year-old children. Literature will be searched across seven databases and considered for inclusion against inclusion and exclusion criteria. Potential implications of the review include informing public health practice and policy for child development and education, informing priorities for speech, language, and communication interventions, and providing directions for future international research.

The influence of active listening on parents' perceptions of clinical empathy in a stuttering assessment: A preliminary study - TERAPIA

Purpose: The primary purpose of this preliminary study was to explore whether a clinician's use of active listening skills (i.e., client-directed eye gaze and paraphrasing) influenced parents' perceptions of clinical empathy in a stuttering assessment. A secondary purpose was to determine whether parent age, education, or parent concern predicted perceived clinical empathy.

Method: Participants (n = 51 parents/guardians of children who stutterwatched two counter-balanced videos of a clinician demonstrating either high or low frequency use of active listening skills during the clinician's initial assessment with a standardized patient actor portraying a parent of a child who stutters. After each video, parents rated the clinician's empathy and active listening skills via the Jefferson Scale of Physician Empathy for Observers (JSPEO; Hojat et al., 2017) and the Counselor Activity Self-Efficacy Scales - Modified (Victorino & Hinkle, 2018). Participants then completed a demographic questionnaire and rated their concern about their child's stuttering.

Results: Paired t-tests demonstrated significantly higher ratings of perceived clinical empathy in the high frequency active listening condition compared to the low frequency condition (d = 0.548). Simple linear regression analyses indicated parent age or level of education did not predict perceived clinical empathy. An independent samples t-test indicated that parent concern about stuttering did not predict perceived clinical empathy.

Conclusions: Preliminary findings suggest that the clinician was viewed as significantly more understanding, concerned, and caring (i.e., perceived as empathic) when active listening skills were used. Parents' ratings of empathy on the JSPEO, based on high levels of active listening by the clinician, were not associated with parents' ages, education levels, or concern about their children's stuttering. This may reflect the value of active listening in clinical relationships regardless of variables specific to the recipient (e.g., parent of a child who stutters). Given that parents are more apt to share thoughts and emotions about their child's communication with clinicians who demonstrate empathic qualities, this preliminary study suggests that the use of active listening skills warrant emphasis in clinical training.

Dysfluent speech has the potential to lower one's standard of living drastically. Although there is a lot of theoretical support for basal ganglia dysfunction in developmental stuttering, there isn't any imaging data to back it up. According to several studies, there is a difference in gray matter volume between people who stammer and those who don't. According to studies, the right inferior longitudinal fasciculus and the uncinate fasciculus have higher fractional anisotropy (FA) than fluent controls. A high fractional anisotropy means good white matter integrity in these areas. In children who stutter, grey matter volume was higher in the Rolandic operculum, middle frontal gyrus, superior temporal gyrus, and inferior parietal lobule. These regions are found to be more active in adults who stammer as their speech fluency improves. Stuttering is previously linked to structural deficiencies in the corpus callosum. However, there are differences in the directionality of the findings between studies, which are unknown. According to current theories, stuttering is caused by a breakdown in the integration of auditory data in speech motor planning, which affects behavior tasks that rely on basal ganglia structures. According to some studies, connectivity in the left inferior frontal gyrus (IFG) and basal ganglia of persons with stuttering (PWS) was significantly reduced. Still, it was more robust in the left supplementary motor cortex (SMC) and premotor cortex (PMC) (primary motor cortex). In the Broca's region, there was also decreased perfusion and spectroscopic indicators of neuronal density. Spontaneous speech is more affected by stuttering than conversation, reading, sentence repetition, or singing. As per the dual process theory of language formation, the basal ganglia are essential for formulaic phrases, but the left hemisphere is important for innovative, freshly constructed sentences. According to current theories on their functional traits and connections to cortical areas of control, the basal ganglia are the complex networks in charge of organizing, initiating, carrying out, and controlling motor behaviors. Given the distinct neuroanatomical characteristics of people who stutter, more research into this cohort is required to further our understanding of the illness. The primary goal of this review article is to fill in any knowledge voids between the neuroanatomical structure of the basal ganglia and the onset of stuttering.

Purpose: This study reports the development, refinement, and exploration of the psychometric properties of the Vanderbilt Responses to Your Child's Speech (VRYCS) rating scale, a novel measure designed to assess parents' self-perceived responses to the speech of their children who stutter (CWS).

Method: Parents of 214 young (ages 2;4[years;months]-5;11) CWS completed the original 40-item version of the VRYCS. Content analyses and an exploratory factor analysis determined the scale's factors and identified specific items corresponding to each. Items that did not load onto the factors were removed and internal consistency was assessed.

Results: The final 18-item VRYCS rating scale includes five factors relating to parents' responses to the speech of their CWS including (a) Requesting Change, (b) Speaking for the Child, (c) Supporting Communication, (d) Slowing and Simplifying, and (e) Responding Emotionally. Reliability was demonstrated, responses by parents of CWS were described, and a revised scoring form developed.

Conclusions: The VRYCS is a valid and reliable tool for assessing and exploring parents' perceptions of their own responses to the speech of their CWS for clinical and research purposes. Clinical applications of the VRYCS for assessment and treatment of childhood stuttering are discussed.

Validity and reliability of safety behaviors questionnaire for Persian adults who stutter: A cultural perspective - AVALIAÇÃO

J Commun Disord. 2022 Aug 10;100:106251. Online ahead of print.

Introduction: Adults who stutter (AWS) are reported to have higher social anxiety compared to those who do not stutter. Previous studies have suggested that safety behaviors, which are cognitive or behavioral strategies used by people with anxiety to prevent negative consequences, are important factors in maintaining anxiety. However, the frequency and types of such behaviors might vary in different cultures. Therefore, the aim of the present study was to develop a transcultural adaptation of Safety Behaviors Questionnaire (Helgadottir et al., 2014) for Persian-speaking AWS and assess its validity and reliability.

Methods: In the first step, the original English questionnaire was translated into Persian using the International Quality of Life Assessment (IQOLA) method. Then, 17 speech and language pathologists (SLPs) and 5 AWS evaluated all questionnaire items using Likert scales to determine face validity. Finally, 167 Persian-speaking AWS completed the questionnaire to assess its construct validity and reliability. Their responses were analyzed using factor analysis and Cronbach's Alpha.

Results: Some items of the original questionnaire were modified or combined with other similar items after assessing the face validity of the Persian-translated questionnaire. Construct validity analysis categorized the remaining 29 questionnaire items into four factors: general avoidance, practice and control, rehearsal, and choosing safe and easy people. The high Cronbach's Alpha of 0.89 for all items confirmed the internal reliability of the Persian-translated questionnaire.

Discussion/conclusions: The results confirmed the psychometric characteristics of the Persian- translated version of the Safety Behaviors Questionnaire (Helgadottir et al., 2014); therefore, speech pathologists can apply it in future clinical and research settings. Similar to Australian AWS, Persian participants of this study self-reported use of various types of safety behaviors frequently.

What Is the Role of Questioning in Young Children's Fluency? INFANTIL / AMBIENTE

Am J Speech Lang Pathol. 2022 Sep 1;1-17. Online ahead of print.

University of Maryland, College Park.


Purpose: Most therapy programs for young children who stutter (CWS) involve caregiver counseling and adjustment of caregiver behavior to maximize opportunities for the child to be more fluent. One component sometimes included as a recommended adjustment is a reduction in caregiver question asking, as question asking is hypothesized to increase language formulation demands on the child. However, there is limited research to guide clinician advisement to caregivers that has controlled for numerous potential confounding factors, including utterance length and grammaticality, that may impact potential stressors on children. Our aim was to assess whether there was an empirical basis for such recommendations by comparing disfluency profiles of answers to questions and nonanswer utterances produced by children during spontaneous play with parents and examiners.

Method: We analyzed fluency and structural properties as well as pragmatic function of 15,782 utterances from language samples produced by 32 CWS and 32 children who do not stutter (CWNS) who were between 28 and 50 months of age. CWS and CWNS were matched on gender and age within 4 months and were matched as closely as possible on maternal education.

Results: For utterances produced by CWS, answers to adult questions were significantly less likely to contain stuttering-like disfluencies than other utterance types, and this was still true after controlling for utterance length and grammaticality. In contrast, for utterances produced by CWNS, answers to questions were significantly more likely to be disfluent than other utterance types after controlling for length and grammaticality.

Conclusion: Given the current findings, some prior research, and the documented potential benefits in language development for adult question asking of children, we do not believe that clinicians need to recommend changes to typical question-asking behavior by caregivers of CWS.
