Bernardini S, Onnivello S, Lanfranchi S. Italian normative data for the Unhelpful Thoughts and Beliefs about Stuttering (UTBAS) Scales for adults who stutter. JOURNAL OF FLUENCY DISORDERS 2024; 81:106074. [PMID: 38968740 DOI: 10.1016/j.jfludis.2024.106074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 02/27/2024] [Accepted: 03/07/2024] [Indexed: 07/07/2024]
Abstract
PURPOSE This study aimed to assess the reliability and validity of the Italian translation of the Unhelpful Thoughts and Beliefs about Stuttering (UTBAS) scales for adults who stutter, as there are no assessment tools currently available in Italy. The UTBAS scales provide a comprehensive stuttering-specific measure of the unhelpful thoughts and beliefs that can be used to screen for indicators of social anxiety in adults who stutter. Additionally, the UTBAS scales also allow the identification of negative thoughts and beliefs that negatively impact speech treatment outcomes. METHOD The translation of the UTBAS scales into Italian (UTBAS-ITA) was completed using the forward-backward translation process and it was administered to 98 adults who stutter (AWS) and 98 adults who do not stutter (AWNS). Both groups were matched for gender and age. We also administered the UTBAS-ITA to 76 AWS a second time within a two-week interval to assess test-retest reliability. Additionally, we administered the State-Trait Anxiety Inventory and the Fear of Negative Evaluation Scale to 20 AWS to assess concurrent validity. RESULTS The UTBAS-ITA showed good power of discrimination between AWS and AWNS, high internal validity, high internal consistency, good construct validity, and good test-retest reliability. CONCLUSION Since there is a scarcity of clinical assessment tools for adults who stutter in Italy, the UTBAS-ITA could serve as an assessment tool and outcome measure for clinical and research environments.

Abstract
Do adults who stutter have abnormally high social anxiety? Is it related to maladaptive cognition? As these are persistent, unresolved questions in stuttering research, it behooves clinicians to at least assess and attempt to identify social anxiety in patients who stutter and its basis before decisions are made about stuttering treatment. The Unhelpful Thoughts and Beliefs About Stuttering (UTBAS) scale is a self-administered questionnaire that measures the degree of non-adaptive cognition in people who stutter (PWS) due to social anxiety. The 66-item UTBAS is time-consuming to complete, prompting the development of a shorter 6-item version, the UTBAS-6, which is in English. Here, we aimed to assess some psychometric properties of the Japanese version of the UTBAS-6, the UTBAS-6-J, which has not been done to date. In 56 adult patients (mean 32.6 ± 11.1 years) who stutter, we quantified the reliability, the internal consistency, and the concurrent validity of the UTBAS-6-J. Along with the UTBAS-6-J, patients also were administered the Overall Assessment of the Speaker's Experience of Stuttering - Japanese version (OASES-A-J), the Modified Erickson Communication Attitude Scale - Japanese version (S-24-J), and the Liebowitz Social Anxiety Scale - Japanese version (LSAS-J). Cronbach's alpha for UTBAS-6-J total scores was 0.974, indicating excellent internal consistency. UTBAS-6-J scores were significantly correlated with scores on the OASES-A-J, the S-24-J, and the LSAS-J (all p < 0.005). Concurrent validity of the UTBAS-6-J with these three questionnaires was confirmed. The UTBAS-6-J has good internal consistency and concurrent validity, which will aid clinical decision-making about stuttering treatments.

Abstract
Stuttering affects approximately 1 in 100 adults and can result in significant communication problems and social anxiety. It most often occurs as a developmental disorder but can also be caused by focal brain damage. These latter cases may lend unique insight into the brain regions causing stuttering. Here, we investigated the neuroanatomical substrate of stuttering using three independent datasets: (i) case reports from the published literature of acquired neurogenic stuttering following stroke (n = 20, 14 males/six females, 16-77 years); (ii) a clinical single study cohort with acquired neurogenic stuttering following stroke (n = 20, 13 males/seven females, 45-87 years); and (iii) adults with persistent developmental stuttering (n = 20, 14 males/six females, 18-43 years). We used the first two datasets and lesion network mapping to test whether lesions causing acquired stuttering map to a common brain network. We then used the third dataset to test whether this lesion-based network was relevant to developmental stuttering. In our literature dataset, we found that lesions causing stuttering occurred in multiple heterogeneous brain regions, but these lesion locations were all functionally connected to a common network centred around the left putamen, including the claustrum, amygdalostriatal transition area and other adjacent areas. This finding was shown to be specific for stuttering (PFWE < 0.05) and reproducible in our independent clinical cohort of patients with stroke-induced stuttering (PFWE < 0.05), resulting in a common acquired stuttering network across both stroke datasets. Within the common acquired stuttering network, we found a significant association between grey matter volume and stuttering impact for adults with persistent developmental stuttering in the left posteroventral putamen, extending into the adjacent claustrum and amygdalostriatal transition area (PFWE < 0.05). We conclude that lesions causing acquired neurogenic stuttering map to a common brain network, centred to the left putamen, claustrum and amygdalostriatal transition area. The association of this lesion-based network with symptom severity in developmental stuttering suggests a shared neuroanatomy across aetiologies.

Abstract
A clinical, evidence-based model to inform clients and their parents about the nature of stuttering is indispensable for the field. In this paper, we propose the Erasmus Clinical Model of Stuttering 2.0 for children who stutter and their parents, and adult clients. It provides an up-to-date, clinical model summary of current insights into the genetic, neurological, motoric, linguistic, sensory, temperamental, psychological and social factors (be it causal, eliciting, or maintaining) related to stuttering. First a review is presented of current insights in these factors, and of six scientific theories or models that have inspired the development of our current clinical model. Following this, we will propose the model, which has proven to be useful in clinical practice. The proposed Erasmus Clinical Model of Stuttering visualizes the onset and course of stuttering, and includes scales for stuttering severity and impact, to be completed by the (parent of) the person who stutters. The pathway of the model towards stuttering onset is based on predisposing and mediating factors. In most children with an onset of stuttering, stuttering is transient, but if stuttering continues, its severity and impact vary widely. The model includes the circle of Engel (1977), which visualizes unique interactions of relevant biological, psychological, and social factors that determine the speaker's experience of stuttering severity and its impact. Discussing these factors and their interaction with an individual client can feed into therapeutic targets. The model is supplemented by a lifeline casus.

Abstract
PURPOSE The purpose of this study was to investigate the emotional and stuttering experience of adults who stutter (AWS) in everyday life, and how that experience may be shaped by personal (i.e., trait social anxiety) and situational factors (i.e., social partner reaction, communication channel type, social closeness, stuttering knowledge). METHOD AWS completed ecological momentary assessments on their smartphones multiple times a day for up to three weeks. Data (n = 62) were analyzed with multilevel models to determine how situational factors and trait social anxiety influence the Negative Affect (NA), Positive Affect (PA), and self-reported stuttering severity of AWS. RESULTS Results indicated that having high (vs. low) trait social anxiety was associated with a tendency to experience high NA, low PA, and high self-reported stuttering severity among AWS. A range of situational factors significantly influenced the within-person variation of NA, PA, and self-reported stuttering severity in everyday life. In addition, interacting with distant social partners relative to being alone heightened NA, and the effect was more prominent among AWS with high (vs. low) trait social anxiety. CONCLUSIONS Overall, the findings suggest that the variation of affects and stuttering severity among AWS can be partly accounted for by factors from both the situational and personal levels. Clinicians should be aware of the low PA experienced by AWS who have high (vs low) trait social anxiety in everyday life.

Abstract
PURPOSE Our study aimed to translate the Stuttering Generalization Self-Measure (SGSM) into Persian and investigate its validity, reliability, and internal responsiveness in the Iranian population. METHOD This study was conducted on 30 adults who stutter (AWS) and 30 adults who do not stutter (AWNS). The International Quality of Life Assessment protocol (IQOLA) was applied to translate SGSM into Persian. The face and content validity were determined. Also, the discriminant validity was evaluated by comparing the scores of two groups. In addition, the internal consistency test-retest, and inter-judge reliability were assessed with Cronbach's alpha and intra-class correlation coefficients (ICC). Moreover, the mean standardized response (MSR) and the standardized effect size were measured to determine the internal responsiveness using pre- and post-treatment data. RESULTS All the items were comprehensible and clear. The content validity ratio (CVR) and content validity index (CVI) for all nine questions were obtained higher than.62 and.9, respectively. The internal consistency value was high (Cronbach's alpha =.98). For the test-retest reliability, ICC values were excellent, ranging from.93 to.99. The discriminant validity results revealed a significant difference between AWS and AWNS (p < .001). Pre- and post-treatment results indicated high internal responsiveness to changes for percentage of syllable stuttered (SS%) (MSR = 1.09). CONCLUSION The Persian version of SGSM (P-SGSM) benefits from the high values for validity and reliability. Furthermore, it distinguishes the AWS and AWNS and reflects the treatment changes significantly.

Abstract
Stuttering poses challenges to social, occupational, and educational aspects of life. Traditional behavioral therapies can be helpful but effects are often limited. Pharmaceutical treatments have been explored but there are no FDA-approved treatments for stuttering. Interest has grown in the potential use of classic psychedelics, including psilocybin and LSD, which have shown effectiveness in treating disorders with similar symptoms (e.g., anxiety, depression, PTSD). The potential effects of psychedelics on stuttering have not been explored. We conducted a preliminary investigation of self-identified stutterers who report their experiences taking classic psychedelics on the online messaging forum, Reddit. We qualitatively analyzed 114 publicly available posts, extracting meaningful units and assigning descriptor codes inductively. We then deductively organized responses into an established framework of psychedelics which includes behavioral, emotional, cognitive, belief-based, and social effects. These effects were subsequently grouped under organizing themes (positive, negative, neutral). Descriptive statistics revealed that the majority of users (74.0%) reported positive overall short-term effects particularly related to behavioral and emotional change (e.g., reduced stuttering and anxiety), but negative (9.6%), mixed (positive and negative; 4.8%), and neutral overall experiences (11.6%) were also reported. The results support the possibility that psychedelics may impact stuttering, but caution must be applied in their interpretation given the entirely uncontrolled research setting and potential adverse health effects of psychedelics as reported elsewhere. While these results do not encourage the use of psychedelics by stutterers, they suggest that future work could examine the impact of psychedelics on stuttering under supervised and in clinically controlled settings.

Abstract
INTRODUCTION The aim of this study was to examine possible associations of social anxiety (SA) and speaking-related physiological reactivity with the frequencies of a) total disfluencies, b) typical disfluencies, and c) stuttering-like disfluencies, as well as d) stuttering-severity in autistic young adults and controls. METHODS Thirty-two autistic young adults and 35 controls participated in this study. Participants were presented with video clips (viewing condition) and were then asked to talk about the videos (narrating condition). SA was measured by the self-report Social Phobia and Anxiety Inventory (SPAI). Speaking-related physiological reactivity was measured by the electrodermal activity (EDA), an index of emotional arousal. The speech samples from the narrating condition were analyzed for type and frequency of speech disfluencies and used for determining the stuttering severity. SA and speaking-related physiological reactivity were compared between the groups. Correlation between SA, physiological reactivity, disfluency frequencies, and stuttering severity were tested separately for both groups. RESULTS No between-group differences were found in the overall SA, yet differences were found in SPAI subscales of social interaction, group interaction, and avoidance, as well as in agoraphobia. Both groups had higher physiological arousal in narrating condition in comparison to the video viewing condition, yet there was no between-group difference in the reactivity. No associations were found between SPAI measures, physiological reactivity, disfluency frequencies, and stuttering severity in the autistic group. In the control group, a negative association was found between physiological reactivity and total and typical disfluency frequencies. CONCLUSIONS SA or speaking-related physiological reactivity were not associated with disfluency frequencies or stuttering severity in autistic persons. Negative association between physiological reactivity and disfluency frequencies found in the control group may indicate that the physiological arousal may impact the speech production process by reducing the overt disfluencies.

Abstract
Stuttering, affecting approximately 1% of the global population, is a complex speech disorder significantly impacting individuals' quality of life. Prior studies using electromyography (EMG) to examine orofacial muscle activity in stuttering have presented mixed results, highlighting the variability in neuromuscular responses during stuttering episodes. Fifty-five participants with stuttering and 30 individuals without stuttering, aged between 18 and 40, participated in the study. EMG signals from five facial and cervical muscles were recorded during speech tasks and analyzed for mean amplitude and frequency activity in the 5-15 Hz range to identify significant differences. Upon analysis of the 5-15 Hz frequency range, a higher average amplitude was observed in the zygomaticus major muscle for participants while stuttering (p < 0.05). Additionally, when assessing the overall EMG signal amplitude, a higher average amplitude was observed in samples obtained from disfluencies in participants who did not stutter, particularly in the depressor anguli oris muscle (p < 0.05). Significant differences in muscle activity were observed between the two groups, particularly in the depressor anguli oris and zygomaticus major muscles. These results suggest that the underlying neuromuscular mechanisms of stuttering might involve subtle aspects of timing and coordination in muscle activation. Therefore, these findings may contribute to the field of biosensors by providing valuable perspectives on neuromuscular mechanisms and the relevance of electromyography in stuttering research. Further research in this area has the potential to advance the development of biosensor technology for language-related applications and therapeutic interventions in stuttering.

Abstract
PURPOSE Heightened rates of social anxiety have been reported in adults who stutter (AWS), but it is unclear whether anxiety is heightened also in children who stutter (CWS). Objective neurophysiological responses such as the error-related negativity (ERN) have been associated with anxiety, and ERN was reported to be increased in AWS. In this study, we examined whether ERN and error positivity (Pe) are increased in CWS. We further characterized ERN associations with age and anxiety in CWS relative to children who do not stutter (CWNS). METHODS EEG data were recorded from twenty-four CWS and twenty-four matched CWNS aged 3-9 years as they performed a Go/No-Go task. Parent-reported anxiety, and child-reported speech-associated attitude measures were collected. Linear regression models tested the effects of age, group, and their interaction, and the effects of anxiety, group, and their interaction on ERN and Pe. RESULTS Contrary to expectations, no ERN or Pe difference were observed between CWS and CWNS. However, larger ERN amplitudes were associated with older age in CWS but not CWNS, suggesting altered development of the error monitoring system in CWS. Association of Pe with anxiety also differed between groups: smaller Pe amplitudes were associated with higher level of parent-reported child anxiety in CWNS but not in CWS. Neither anxiety nor self-reported communication attitude differed between groups. CONCLUSIONS Brain responses to errors were overall comparable between CWS and CWNS. However, CWS differed in how error monitoring responses varied with age and with anxiety levels. More research is warranted to examine how these factors contribute to persistent stuttering.

Abstract
This study investigated whether multilinguals who stutter differ from multilinguals who do not stutter in terms of attention networks. Towards that end, it measured (a) performance differences in attention networks between multilinguals who stutter and those who do not stutter and (b) the correlation between stuttering characteristics and attention networks. Twenty-four multilingual Dutch-English speaking adults (20-46y), half of whom were diagnosed with stuttering, completed the Attentional Network Task (ANT) that evaluates the attention networks of alerting, orienting, and executive control. A language and social background questionnaire and a lexical decision task (LexTALE) assessed the participants' language proficiency. The Stuttering Severity Instrument 4th Ed. and the Brief Version of the Unhelpful Thoughts and Beliefs About Stuttering Scale were used to evaluate stuttering characteristics. The two groups did not differ in the ANT in terms of reaction time and error rate scores. Furthermore, no differences were observed in the three attention networks between the groups. Lastly, no correlation was found between stuttering characteristics and attention networks. The results suggest that the attention abilities of multilinguals who stutter do not differ from multilinguals who do not stutter.

Abstract
PURPOSE People who stutter (PWS) are vulnerable to the development of various psychopathological symptoms, although prevalence data are mixed and less clarity exists about factors that potentially influence their occurrence. The current study sought to shed light on the prevalence of self-reported psychopathology in PWS and aimed to identify relationships between affective, behavioral, and cognitive (ABC) experiences of stuttering and psychological distress (PD). METHOD Forty-four PWS were administered the Behavior Assessment Battery (BAB) for Adults who Stutter and the Brief Symptom Inventory-18. The prevalence of clinically significant PD was calculated via BSI-18 global severity index t-score cutoffs. Regression analyses examined relationships between ABC variables of stuttering and PD. RESULTS Participants' BAB scores approximated normative values, while the PD score distribution was similar to that of a nonclinical sample. Nine percent of participants met thresholds for clinically significant PD. All ABC correlates of stuttering significantly and positively correlated with PD scores, capturing considerable amounts of shared variance. CONCLUSIONS Levels of PD in PWS approximate those of the general community, highlighting the existence of psychologically distressed subgroups of PWS. Speech situation-specific anxiety had the strongest relationship to PD, followed closely by one's report of situation-specific speech disruption. To a lesser but still significant extent, PWS' frequency to which they engage in various avoidance/escape behaviors, as well as their communication attitude, predicted levels of psychopathology. These data inform diagnostic and clinical decision making, drawing attention to factors that should be attended to in treatment.

Abstract
PURPOSE For those who stutter, verbal communication is typically compromised in social situations. This may attract negative responses from listeners and stigmatization by society. These have the potential to impair health-related quality of life across a range of domains, including qualitative and quantitative impacts on speech output, mental health issues, and failure to attain educational and occupational potential. These systematic reviews were designed to explore this matter using traditional health economics perspectives of utility measures and cost of illness. METHOD Studies were included if they involved children, adolescents, or adults with stuttering as a primary diagnosis. The quality of life search strategy identified 2,607 reports, of which three were included in the quality of life analysis. The cost of illness search strategy identified 3,778 reports, of which 39 were included in the cost of illness analysis. RESULTS Two of the three studies included in the quality of life analysis had a high risk of bias. When measured using utility scores, quality of life for people who stutter was in the range of those reported for chronic health conditions such as diabetes mellitus, cardiovascular disease, and cancer. However, there is little such evidence of quality of life impairment during the preschool years. Studies included in the cost of illness analysis carried considerable risk of bias overall. CONCLUSIONS For people who stutter, there are substantive direct and indirect costs of illness. These include impairment, challenges, and distress across many domains throughout life, including income, education, employment, and social functioning. Evidence of quality of life impairment using utility measures is extremely limited. If this situation is not remedied, the lifetime impairment, challenges, and distress experienced by those who stutter cannot be documented in a form that can be used to influence health policy and health care spending.

Abstract
Interpreting can be seen as a form of language production, where interpreters extract conceptual information from the source language and express it in the target language. Hence, like language production, interpreting contains speech errors at various (e.g., conceptual, syntactic, lexical and phonological) levels. The current study delved into the impact of language proficiency, working memory, and anxiety on the occurrence of speech errors across these linguistic strata during consecutive interpreting from English (a second language) into Chinese (a first language) by student interpreters. We showed that speech errors in general decreased as a function of the interpreter's proficiency in the source (second) language and increased as a function of the interpreter's anxiety. Conceptual errors, which result from mistaken comprehension of the source language, decreased as a function of language proficiency and working memory. Lexical errors increased as a function of the interpreter's tendency of anxiety. Syntactic errors also decreased as a function of language proficiency and increased as a function of anxiety. Phonological errors were not sensitive to any of the three cognitive traits. We discussed implications for the cognitive processes underlying interpreting and for interpreting training.

Abstract
Stuttering is a fluency disorder that is multidimensional because it involves more than speech difficulties. People who stutter can use the Internet to find out more about their condition and connect with other people in the same position, yet in Croatia, there are not nearly as many online sources on stuttering or as many possibilities to connect with other people who stutter as in the USA or Great Britain. If one does not speak English well, a lot of information about stuttering will simply be denied to them, especially to those who have never received speech therapy. The present study, the first of its kind in Croatia, was conducted in order to understand how often and for what reasons people who stutter search for Internet resources related to their condition. The study also assessed whether Internet use depended on age, experience with speech-language therapy, self-reported satisfaction with such therapy, and self-assessed severity of stuttering. An online questionnaire integrating the 9-Point Stuttering Severity Scale was developed for this study and administered to 51 individuals aged 18 years and older in Croatia. All collected data and findings on the internet searches come from the questionnaire. Age did not significantly affect the frequency or purpose of Internet searches. Individuals who were not attending speech therapy were more likely to search online sources about stuttering than those who received it before. People who rated their stuttering as severe were more likely to search online sources for stuttering than those who rated their condition as mild. These results suggest that there is a need for more useful, high-quality online content and materials in Croatian for people who stutter. Such resources would offer people who stutter a new world of support, mutual understanding, shared experiences and knowledge, and ways for them to help themselves.

Abstract
PURPOSE The purpose of this study was to determine if self-stigma-related variables predicted communicative participation and mental health in adults who stutter. A progressive model of self-stigma was theorized and tested. METHOD Adults who stutter (N = 344) completed a survey that included measures of communicative participation, global mental health, and a variety of self-stigma-related variables including perceived enacted stigma, stigma awareness, anticipated stigma, felt stigma, stereotype agreement, and stigma application, in addition to demographic and speech-related variables. Hierarchical regression was performed to test whether self-stigma-related variables progressively explained significant variance in both communicative participation and global mental health.c Results: After controlling for demographic and speech-related variables, stigma-related variables were found to be significant predictors of both communicative participation and global mental health among adults who stutter. Most self-stigma-related variables entered later in the model predicted additional unique variance in the outcome variables than the self-stigma-related variables entered in previous steps, thus supporting the trickle-down and progressive nature of the self-stigma model theorized. CONCLUSIONS Accounting for self-stigma in the assessment and treatment of individuals who stutter may identify and ultimately reduce environmental and personal barriers to communicative functioning and well-being in people who stutter. The self-stigma terminology and model described in this study will help practitioners, researchers, and the public better understand the process of self-stigma and how it may be associated with adverse outcomes experienced by people who stutter.

Abstract
PURPOSE Research indicates that there is a tendency for females who stutter, more often than males, to use coping strategies that involve covering their stutter, for example, by avoiding situations that require verbal participation. The aim of the study is to increase knowledge about how covert stuttering develops and its impact on self-image and quality of life for women who stutter. METHOD Eleven young women who stutter covertly were interviewed, and data were subjected to qualitative content analysis. Background information was obtained from the self-report instruments measuring the impact of stuttering on different aspects of life (Overall Assessment of the Speaker's Experiences of Stuttering) and degree of perceived social anxiety (Liebowitz Social Anxiety Scale, Self-Report). RESULTS Three main themes were identified: (a) managing stuttering, (b) personal aspects, and (c) stuttering as a phenomenon. Shame and a desire to fit in emerged as distinct motives for covering stuttering. The women described that stuttering controlled both life choices and everyday life. Development of self-image had been strongly negatively affected, resulting in social anxiety. The women expressed a particular vulnerability of being a woman who stutters, due to societal norms of female behavior and a lack of female role models who stutter. CONCLUSIONS The choice of coping strategy was motivated by a desire to "be normal." As a result, stuttering had come to dominate life and affect self-image and life choices. The study highlights the importance for clinicians to be alert to and aware of the fact that the experiences of women who stutter can lead them to develop coping strategies that have far-reaching negative consequences.

Abstract
PURPOSE We sought to investigate the effects of cued attentional shifts on speechmotor control in adults who stutter (AWS) and adults who do not stutter (ANS) when speaking under low and high social stress conditions. METHOD Thirteen AWS' and 10 ANS' lip aperture (LA) and posterior tongue (PT) movements were assessed under a Cued-Internal and Cued-External attentional focus condition with and without social stress induction (i.e. speaking to an audience). Skin conductance levels were used to measure a stress response. Speech motor control was assessed by measuring movement duration and variability of movement for LA and PT using the spatial temporal index (STI). RESULTS A significant Group x Condition interaction was found for LA STI. Post-hoc comparisons indicated AWS' LA STI significantly decreased under Cued External Focus conditions during both low and high social stress. No significant Group x Condition interaction was found for PT STI. AWS showed significantly slower tongue movements (PT) across all low and high social stress conditions; however, there was no significant Group x Condition interaction for PT or LA. DISCUSSION Findings yield preliminary insights into the role of attentional focus on speech motor control when speaking during high social stress. Theoretical and clinical implications are discussed.

Abstract
PURPOSE The purpose of this study was to investigate whether 3- to-6-year-old children who stutter and exhibit a higher degree of behavioral inhibition (BI), a correlate of shyness, stutter more frequently and experience greater negative consequences of stuttering (per parent-report) than their peers who stutter but have lower BI. METHOD Forty-six children who stutter (CWS; 35 boys & 11 girls; mean age 4 years, 2 months) participated. Their degree of BI was assessed by measuring the latency to their 6th spontaneous comment during a conversation with an unfamiliar examiner (following Kagan, Reznick, & Gibbons's (1989) methodology). The frequency of stuttering and the negative impact of stuttering that CWS may have experienced was assessed using parent reports (i.e., Test of Childhood Stuttering (TOCS) Observational Rating Scale; Gillam, Logan, & Pearson, 2009). RESULTS We found that children's degree of BI was not associated with their speech fluency per parent report. However, children's degree of BI was significantly associated with greater negative consequences of stuttering. Specifically, among the four categories of TOCS Disfluency-Related Consequences, children's BI significantly predicted the occurrence of physical behaviors that accompany moments of stuttering (such as increased tension or excessive eye blinks). Other Disfluency-Related Consequences, such as avoidance behaviors, negative feelings, and negative social consequences, were not associated with children's behavioral inhibition tendencies. Additionally, children's stuttering severity (per the Stuttering Severity Instrument-4 scores) was significantly associated with increased physical behaviors that accompany moments of stuttering and greater negative social consequences of stuttering. CONCLUSIONS This study provides empirical evidence that behavioral inhibition to the unfamiliar may have salience for childhood stuttering as it predicted the development of physical behaviors associated with stuttering (e.g., tension or struggle) in 3- to 6-year-old CWS. Clinical implications of high BI for the assessment and treatment of childhood stuttering are discussed.

Abstract
INTRODUCTION Psychosocial aspects of stuttering may affect the quality of life of a person who stutters (PWS). Further, the social stigma and experiences of PWS may vary globally. The WHO-ICF guidelines recommend quality of life as an essential component in the assessment of individuals who stutter. However, the availability of linguistically and culturally appropriate tools is often a challenge. Thus, the current study adapted and validated the OASES-A for Kannada-speaking adults who stutter. METHOD The original English version of OASES-A was adapted to Kannada using a standard reverse translation process. The adapted version was administered on 51 Kannada-speaking adults with very mild to very severe stuttering. The data were analyzed for item characteristics, reliability, and validity assessment. RESULTS The results revealed floor and ceiling effects for six and two items, respectively. The mean overall impact score indicated a moderate impact of stuttering. Further, the impact score for section II was relatively higher when compared to the data from other countries. The reliability and validity analyses showed good internal consistency and test-retest reliability for OASES-A-K. CONCLUSION The findings of the current research suggest that OASES-A-K is a sensitive and reliable tool to assess the impact of stuttering in Kannada-speaking PWS. The findings also highlight cross-cultural differences and the need for research in this direction.

Abstract
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 anlanguage 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. WHAT THIS PAPER ADDS What is already known on the subject The Lidcombe Program is an efficacious early stuttering intervention. Translation to clinical communities has been studied with one Australian cohort. What this paper adds to existing knowledge A larger translation cohort is studied, comprising community clinicians and children in Australia and England. What are the potential or actual clinical implications of this work? 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.

Abstract
PURPOSE The purpose of this study was to analyse naïve listener perceptions of speech containing unmodified stuttering, use of the pull-out technique, and use of preparatory-sets. METHOD Participants (N = 62) were randomly assigned to listen to one audio sample (unmodified stuttered speech, speech with pull-outs, or speech with preparatory-sets) and completed a survey assessing perceptions of the speaker's speech and personality and the listener's comfort level and willingness to social interact with the speaker. RESULTS Survey results revealed low perceptual ratings in all experimental conditions. Unmodified stuttered speech received significantly more positive ratings than the stuttering modification conditions in all measurements except for speech naturalness. Listeners reported being less willing to socially interact with those who use preparatory-sets than unmodified stuttered speech. CONCLUSION The use of stuttering modification techniques did not improve listeners' perceptions or willingness to interact with persons who stutter. Clinicians and those who stutter should be aware that the use of speech techniques will not decrease negative social interactions or stereotypes.

Abstract
PURPOSE Children and adolescents who stutter may be at risk of elevated anxiety and depression symptoms, although studies have indicated variability in reported internalizing symptoms in this population. This study considers the association between anxiety and depression symptoms and stuttering, as well as child, family, and contextual factors that may affect this association. METHOD Thirty-five school-age children who stutter completed the Revised Children's Anxiety and Depression Scale-Short Version. We fitted regression models to examine the association between anxiety and depression symptoms with bullying, stuttering severity, family history of adverse mental health, and age in children who stutter. RESULTS Family history of adverse mental health was found to significantly predict anxiety and depression scores. Age also predicted depression scores, with older children reporting higher scores. CONCLUSIONS Family history of adverse mental health is associated with higher self-reported internalizing symptoms in children who stutter. The interaction between child, family, and contextual factors may change with age, and this requires further exploration in larger, longitudinal studies. The association between bullying and anxiety scores indicates the importance of anti-bullying initiatives in promoting psychosocial development in school-age children who stutter. This study also highlights the contribution of known risk factors for mental health, such as family history, to variability in symptom reporting.

Abstract
We report on findings from the first randomized controlled pilot trial of virtual reality exposure therapy (VRET) developed specifically for reducing social anxiety associated with stuttering. People who stutter with heightened social anxiety were recruited from online adverts and randomly allocated to receive VRET (n = 13) or be put on a waitlist (n = 12). Treatment was delivered remotely using a smartphone-based VR headset. It consisted of three weekly sessions, each comprising both performative and interactive exposure exercises, and was guided by a virtual therapist. Multilevel model analyses failed to demonstrate the effectiveness of VRET at reducing social anxiety between pre- and post-treatment. We found similar results for fear of negative evaluation, negative thoughts associated with stuttering, and stuttering characteristics. However, VRET was associated with reduced social anxiety between post-treatment and one-month follow-up. These pilot findings suggest that our current VRET protocol may not be effective at reducing social anxiety amongst people who stutter, though might be capable of supporting longer-term change. Future VRET protocols targeting stuttering-related social anxiety should be explored with larger samples. The results from this pilot trial provide a solid basis for further design improvements and for future research to explore appropriate techniques for widening access to social anxiety treatments in stuttering.

Abstract
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.

Sleep Problems, Social Anxiety and Stuttering Severity in Adults Who Do and Adults Who Do Not Stutter. J Clin Med 2022; 12:jcm12010161. [PMID: 36614966 PMCID: PMC9821465 DOI: 10.3390/jcm12010161] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Revised: 12/11/2022] [Accepted: 12/18/2022] [Indexed: 12/28/2022] Open
Abstract
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.

Azarinfar M, Karimi H, Jowkar F, Shafiei B. Validity and reliability of safety behaviors questionnaire for Persian adults who stutter: A cultural perspective. JOURNAL OF COMMUNICATION DISORDERS 2022; 100:106251.

Abstract
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.

Abstract
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 speaker, in addition to facilitating positive listener perceptions. Clinicians 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.

Abstract
PURPOSE One way of conceptualizing stuttering is on a continuum from primarily covert to primarily overt. Assertions have been made as to how those with covert stuttering might be impacted differently to those with overt stuttering, but findings from well-controlled studies remain scarce. The principal aim of the present study was to compare the impact of stuttering and emotional distress related to two subgroups of persons who stutter: people with primarily overt stuttering and people with primarily covert stuttering. In exploring this, we also offer some preliminary thoughts on challenges with the terminology surrounding the concepts of 'overtness' and 'covertness'. METHODS Twenty-one adults already enrolled in a multiple, single-case treatment study (Sønsterud et al., 2019, 2020) took part in the present study, and underwent a battery of tests that assessed anxiety, depression, fear of negative evaluation, and quality of life. The sub-groups were identified on the basis of self-categorization using the Tomaiuoli, Del Gado, Spinetti, Capparelli, and Venuti (2015) classification, as well as the evaluation of speech samples from two independent SLPs (Sønsterud et al., 2020). The classifications were further explored by five independent 'lay' assessors who reviewed pre-therapy video and rated participants' speech on a 4-point Likert Stuttering Probability Scale (1 = 'fluent with no doubt', 2 = 'fluent with some doubt', 3 = 'stuttering with some doubt' and 4 = 'stuttering with no doubt'). RESULTS No significant differences were found between the primarily overt and primarily covert groups in relation to self-reported symptoms of anxiety, depression, and fear of negative evaluation. However, investigation at item level identified a significant difference in linguistic avoidance between the two groups. CONCLUSION There may be fewer differences between people with primarily overt and primarily covert stuttering than previously thought with regards to emotional impact, as well as most aspects of avoidance behavior.

Abstract
Abstract. The relationship between anxiety and stuttering has always been a topic of debate with a great emphasis on research focused on examining whether speech-related anxiety can exacerbate stuttering. This investigation compares some speech-related anticipatory anxiety indices in fluent and dysfluent utterances in adults who stutter (AWS). We scored the level of cognitive speech-related anxiety (anticipatory anxiety) using a self-reporting method and also evaluated the autonomic aspects of anxiety (state anxiety) through recording changes in Galvanic Skin Response (GSR) signals. Explaining the link between stuttering and anxiety is expected to assist practitioners in stuttering assessment and subsequent treatment strategies. Phasic GSR values of six events related to answering the verbal stimuli through fluent and dysfluent responses were registered to measure sympathetic arousal as an index of state anxiety in 20 AWS ( Mage = 35 ± 4 years, range: 21–42). To quantitatively examine the cognitive aspects of speech-related anticipatory anxiety, two questionnaires were rated by participants addressing the stuttering anticipation and semantic difficulty of verbal stimuli. GSR measures of fluent events were significantly higher than dysfluent counterparts within time windows before and during answering aloud the verbal stimuli ( p < .001). Later in the experiment, GSR values of dysfluent events were found to be higher than their fluent counterparts ( p < .001). Stuttering anticipation yielded a weak negative meaningful correlation with the scores of fluency ( r = −0.283, p = .046) and a positive yet nonsignificant correlation with the stuttering scores. The semantic difficulty had a moderately significant correlation with stuttering anticipation ( r = 0.354, p = .012) but not a meaningful correlation with fluency state. Autonomic and cognitive indices of speech-related anticipatory anxiety are not robust predictors of fluency. Anxiety seems to be more of a consequence of stuttering than a cause.

Abstract
PURPOSE This study investigated the complexity of stuttering behavior. It described and classified the complexity of stuttering behavior in relation to age, behavioral treatment outcomes, stuttering severity, anxiety-related mental health, impact of stuttering, and gender. METHOD For this study, a taxonomy was developed-LBDL-C7-which was based on the Lidcombe Behavioral Data Language of stuttering. It was used by five experienced judges to analyze the complexity of stuttering behavior for 84 adults and adolescents before and after speech restructuring treatment. Data were 3,100 stuttering moments, which were analyzed with nominal logistic regression. RESULTS The complexity of stuttering behavior appears not to change as a result of treatment, but it does appear to change with advancing age. Complexity of stuttering behavior was found to be independently associated with clinician stuttering severity scores but not with percentage of syllables stuttered or self-reported stuttering severity. Complexity of stuttering behavior was not associated with gender, anxiety, or impact of stuttering. CONCLUSION Clinical and research applications of these findings are discussed.

Abstract
PURPOSE The aim of this study was to document the behaviors that adults who stutter (AWS) may engage in to make positive changes to living with stuttering. METHOD We interviewed 23 key stakeholders, including 11 AWS and 12 speech-language pathologists who specialize in stuttering therapy. The semi-structured interviews began with the primary question, "If an adult who stutters was making positive changes to living with stuttering, what would they be doing?" Follow-up probing questions focused the interviews on identifying actionable behaviors that would suggest positive changes. The interviews were transcribed and qualitatively analyzed using applied and reflexive thematic analyses to develop multilevel themes. RESULTS Meaningful units extracted from the interviews contributed to three high-order global themes: (a) noticing and adjusting physical behaviors involved in speaking, to the extent that it is personally important to do so; (b) developing neutral or positive thoughts and feelings about stuttering; and (c) participating more fully in social and professional activities, even if the person stutters or thinks they might stutter. We developed 35 low-order basic themes, which we grouped into 11 mid-order organizing themes, to richly illustrate the three global themes. CONCLUSIONS These findings extend the ongoing discussion regarding best practices for therapy targets in stuttering intervention. We identified measurable, multidimensional actions that clinicians can integrate in their therapy plans with AWS. While these actions represent a holistic approach to making positive changes, it grants clients and clinicians space to develop individualized intentions and outcomes.

Abstract
Stuttering is a complex communication disorder with effects that extend beyond difficulty with communication. Negative thoughts and feelings by the person who stutters (PWS), about the disorder or themselves, may potentially lead to detrimental avoidance behaviors which may ultimately alter life choices and participation in life events. One such area is the labor market. Studies have revealed an association between stuttering and reduced earnings. What is not understood is whether provision of speech therapy for PWS can help mitigate the negative labor market impacts of this condition. This article discusses the disorder of stuttering and how approach versus avoidance responses can contribute to wage differentials among PWS, while also providing evidence of such differences using a nationally representative dataset. Additionally, this article outlines the potential benefits received from speech-language pathology services which may correlate with improved labor market outcomes.

METHOD The participants were 132 English-speaking children (105 boys and 27 girls) between 9;0 and 14;11 years old (M = 11;8, SD = 1;10) and their mothers. At their first visit to a specialist center for children who stutter, mothers and children completed the relevant versions of the Early Adolescent Temperament Questionnaire-Revised (EATQ-R; Ellis & Rothbart, 2001) and a screening of children's anxiety and depression, using the Revised Children's Anxiety and Depression Scale (RCADS; Chorpita et al., 2000). Stuttering was evaluated using the Stuttering Severity Instrument Fourth Edition (SSI-4). Correlations were conducted between child and parent versions of the EATQ-R and RCADS; EATQ-R and RCADS; as well as the SSI-4 and RCADS. A comparison was made between those children who scored below the clinical threshold for anxiety and depression, and those who scored above. RESULTS Significant correlations were found for all mother and child EATQ-R factors and RCADS scales (except for Obsessive Compulsive Disorder). Correlations were also found between the child- and mother-reported temperament factors of positive reactivity, negative reactivity, and self-regulation and anxiety and depression. Children who scored above the clinical threshold for any category of anxiety or depression had significantly lower positive reactivity and higher negative reactivity scores, compared to those who scored below the threshold. There were no differences between the two groups with regard to SSI-4 scores. CONCLUSIONS This is the first study to evaluate associations between temperament and anxiety and depression in children who stutter. Higher negative reactivity scores and lower positive reactivity and self-regulation scores are associated with elevated levels of anxiety and depression in children who stutter. Further, those who score above the clinical threshold have significantly higher levels of negative reactivity and lower levels of positive reactivity compared to those scoring below the threshold. Findings suggest that levels of anxiety that reach clinical threshold are more prevalent in children who stutter than would be expected based on population data. Current findings have implications for both the assessment and therapy of children who stutter presenting at clinics for support.

Abstract
Virtual Reality Exposure Therapy (VRET) has been shown to be an effective technique for reducing social anxiety. People who stutter are at greater risk of developing heightened social anxiety. Cognitive behavior therapy protocols have shown promise in reducing social anxiety in people who stutter, but no studies have investigated VRET targeting social anxiety associated with stuttering. The aim of the current review is to provide an overview of VRET techniques used to treat social anxiety and insights into how these techniques might be adopted in the case of comorbid stuttering and social anxiety. Twelve studies were reviewed to understand key distinctions in VRET protocols used to treat social anxiety. Distinctions include exercises targeting public speaking vs. general social anxiety, computer-generated virtual environments vs. 360° video, and therapist guided vs. automated VRET. Based on the review findings, we propose how certain features could be applied in the case of stuttering. Virtual therapists, inhibitory learning techniques and integration into speech therapy may be suitable ways to tailor VRET. Regardless of these different techniques, VRET should consider the situations and cognitive-behavioral processes that underlie the experience of social anxiety amongst people who stutter.

Abstract
PURPOSE The purpose of this study was to investigate whether there are elevated symptoms of anxiety or depression in children and adolescents (aged 2-18 years) who stutter, and to identify potential moderators of increased symptom severity. METHOD We conducted a preregistered systematic review of databases and gray literature; 13 articles met criteria for inclusion. A meta-analysis using robust variance estimation was conducted with 11 cohort studies comparing symptoms of anxiety in children and adolescents who do and do not stutter. Twenty-six effect sizes from 11 studies contributed to the summary effect size for anxiety symptoms (851 participants). Meta-analysis of depression outcomes was not possible due to the small number of studies. RESULTS The summary effect size indicates that children and adolescents who stutter present with increased anxiety symptoms (g = 0.42) compared with nonstuttering peers. There were insufficient studies to robustly analyze depression symptoms, and qualitative review is provided. No significant between-groups differences were reported in any of the depression studies. CONCLUSIONS Preliminary evidence indicates elevated symptoms of anxiety in some children and adolescents who stutter relative to peers. There was a tendency toward higher depression scores in this population, although reported between-groups differences did not reach statistical significance. These findings require replication in larger, preferably longitudinal studies that consider factors that may moderate risk. Nevertheless, our findings highlight a need for careful monitoring of mental health and well-being in young people who stutter. Supplemental Materials: http://osf.io/5m6zv.

Abstract
PURPOSE The proclivity to construe ambiguous information in a negative way is known as interpretation bias, which has been implicated in the onset and/or maintenance of social anxiety. The purpose of this study was to examine group and individual differences in interpretation bias among young people who stutter and their typically fluent peers during the adolescent years when social fears and worries tend to escalate. METHODS A total of 99 adolescents (13 to 19 years old) participated, including 48 adolescents who stutter (67% male) and 51 typically fluent controls (68% male). They completed a computerized vignette-based interpretation bias task in which they first read 14 short ambiguous social scenarios (half including a verbal interaction, half including a non-verbal interaction). They were then presented with four possible interpretations of each scenario including two negative interpretations (one target, one foil) and two positive interpretations (one target, one foil). Participants used a 4-point Likert scale to rate how similar in meaning each interpretation was to the original scenario. Participants also completed self-report measures of social and general anxiety, and provided a speech sample for stuttering analysis. RESULTS There was no effect of stuttering on interpretations; the adolescents who stutter rated interpretations across both verbal and non-verbal scenarios comparably to the controls, and stuttering severity did not affect interpretation ratings. However, across groups, there was a significant effect of social anxiety such that higher social anxiety was associated with more negative interpretations, and lower social anxiety was associated with more positive interpretations. DISCUSSION This study provides preliminary evidence that social anxiety may affect how adolescents interpret ambiguous social cues in verbal and non-verbal scenarios more than stuttering, although more research into how people who stutter process social information is warranted.

Abstract
INTRODUCTION Stuttering is a condition that can be severely disabling in the workplace and socially. Although many stuttering cases resolve, some adults who stutter (AWS) continue to be affected not only by dysfluent speech, but also by other social and psychological conditions that may develop as a result of stuttering. The aim of the present study was to determine the relationship between severity of stuttering, severity of social anxiety, and coping profile. METHODS We objectively assessed adults who stutter (n = 44; mean age = 27.5 years) and age-matched non-stuttering control subjects on four variables: stuttering frequency, communication attitude, social anxiety, and coping profile. Stuttering frequency was calculated as the percentage stuttered morae in the Kitsuon-kensa-ho test. All subjects were assessed on the Japanese versions of the Modified Erickson's Communication Attitude Scale (S-24-J), Liebowitz Social Anxiety Scale (LSAS-J), and the Brief Scale for Coping Profile (BSCP). RESULTS Compared to the non-stuttering group, the stuttering group had a higher average score on the S-24-J and LSAS-J, and tended to "avoid and suppress" instead of "seek help for resolution" on the BSCP. Comparison of individual stutterers' S-24-J scores whose LSAS-J scores were above or below the LSAS-J cutoff score revealed that their the S-24-J scores tended to be higher. Also, BSCP participants tended to engage in "proactive resolution" and "emotional venting involving others," not "seeking help for resolution." The stuttering group (vs. the non-stuttering group) and the high social-anxiety group (vs. the low social-anxiety group) adopted non-adaptive coping strategies. CONCLUSIONS This suggests that the coping profile of AWS may contribute to the cycle of social anxiety and stuttering to a greater or lesser extent. Thus, therapy that reduces anxiety and helps AWS to adopt more adaptive coping strategies may improve stuttering.

Abstract
<b><i>Purpose:</i></b> We know that adults who stutter report higher levels of social anxiety [Craig and Tran: J Fluency Disord 2014;40:35–43; Iverach et al.: J Anxiety Disord 2009;23(7):928–34]. What is not clear is whether adults who stutter develop maladaptive attentional shifts, similar to what is observed in socially anxious individuals, in response to social anxiety. The purpose of this study was to investigate the attentional biases in adults who stutter compared to adults who do not stutter before and after social evaluative threat induction and determine whether responses are associated with objective and subjective measures of anxiety. <b><i>Method:</i></b> Twelve adults who stutter and 14 matched adults who do not stutter performed a modified response time paradigm, the dot-probe task, where they responded to a probe appearing behind one of two faces, one emotional (positive or negative) and one neutral. Participant’s reaction times were measured before and after a social threat induction task. Skin conductance levels were used as an index of induced stress. Self-reports of trait and social anxiety were used as subjective measures of anxiety. <b><i>Results:</i></b> Adults who stutter compared to controls exhibited an attentional bias towards negative facial expressions following a social evaluative threat induction. This effect remained when covarying for levels of trait and social anxiety. Before social evaluative threat induction, visual inspection of the data showed that adults who stutter compared to adults who do not stutter avoided positive facial expressions as they attended more to the negative facial expressions; however, these differences were not significant. <b><i>Discussion:</i></b> This study provides evidence for a maladaptive attentional behavior in adults who stutter when undergoing feelings of social evaluative threat. Results provide rationale for research aimed at assessing the use of attention restructuring in highly anxious adults who stutter.

Abstract
PURPOSE In the current study, stuttering was conceptualized as a concealable stigmatized identity (CSI). The purpose of this investigation was to determine if four specific stigma-identity constructs that contribute to variability in psychological distress among people in other CSI groups also contribute among adult who stutter (AWS). METHOD 505 AWS completed an online survey that included measures of four stigma-identity constructs in addition to general demographics and measures of self-rated stuttering severity, distress, and adverse impact of stuttering on quality of life. Hierarchical regression was performed to determine the extent that stigma-identity constructs explained variability in psychological health outcomes among AWS. Self-rated stuttering severity was investigated as a moderator in these relationships. RESULTS The stigma-identity constructs accounted for a significant proportion of the variability in distress (∼25 %) and adverse impact of stuttering on quality of life (∼30 %) among AWS. Further, the constructs of salience, centrality, and concealment were positively predictive of distress and adverse impact of stuttering after controlling for demographics and neuroticism. Compared to the other predictor variables (self-rated stuttering severity, demographic characteristics, neuroticism, and the three other stigma-identity constructs), concealment was the strongest predictor of adverse impact of stuttering on quality of life. Finally, self-rated stuttering severity was a moderating variable. CONCLUSIONS The results from this study suggest that there are useful applications in conceptualizing stuttering as a type of CSI. Speech-language pathologists should be aware of the relationships that stigma has with psychological health outcomes among AWS and should consider the implications for intervention.

Abstract
PURPOSE The purpose of this study was to investigate resting autonomic activity in adults who stutter (AWS) compared to adults who do not stutter (ANS) and the relationship this has on self-reports of social anxiety. METHODS Thirteen AWS and 15 ANS completed the Social Interaction Anxiety Scale (SIAS; Mattick & Clark, 1998) and Brief Fear of Negative Evaluation (BFNE; Leary, 1983). Following this, measures of skin conductance levels (i.e. index of sympathetic activity) and respiratory sinus arrhythmia (i.e. index of parasympathetic activity) were taken during a 5-minute resting, baseline period. Independent sample t tests were used to assess differences between groups on self-reports of anxiety (SIAS, BFNE) and resting autonomic levels (SCL, RSA). Separate multiple regression analyses were performed in order to assess the relationship between self-reports of anxiety and autonomic measures. RESULTS Results showed significantly higher mean SCL and lower mean RSA levels in the AWS compared to the ANS at resting, baseline. Regression analysis showed that self-reports from the SIAS had a significant effect on RSA levels for the AWS but not the ANS. No significant effects were found for BFNE on RSA. Nor was there a significant effect from SIAS or BFNE on SCL levels for either group. CONCLUSION Findings suggest that resting RSA levels may be a physiological marker for social anxiety levels in adults who stutter.

Abstract
Purpose This study measured between-groups differences in perceived speech skills and personality characteristics of a 12-year-old male child who stutters (CWS) as a function of a written factual stuttering disclosure statement, delivered by the CWS, his "mother," or his "teacher." Method Four hundred twenty-four college-age adults were assigned to one of four groups, including three experimental groups (i.e., written self-disclosure, mother-written disclosure, and teacher-written disclosure) and a control group (no written disclosure). Participants in the control conditions viewed a brief video of the CWS. In the experimental conditions, participants read a brief written disclosure statement for 30 s, followed by the same video used in the control condition. After viewing the video, all participants completed surveys relative to their perceptions of the CWS speech skills and personality characteristics. Results Results reveal that a written stuttering disclosure statement provided by the mother correlated with select significant desirable perceptual differences of the CWS, while a written disclosure statement provided by the CWS yielded insignificant or even undesirable perceptual differences of the CWS. Written stuttering disclosures provided by a "teacher" did not yield any significant between-groups differences in the perception of a CWS. Gender affiliation was found to be a source of covariance in a number of perceived speech skills and personality characteristics. Conclusions Written stuttering disclosure statements provided by the "mother" correlated with select favorable perceptual differences of speech skills and personal characteristics of a CWS. Clinically, the application of novel methods (written and oral disclosure statements) and sources (i.e., CWS advocates such as "mother" and "teacher") of stuttering disclosure statement can be integrated into a systematic therapeutic program, creating an innovative approach of scaffolding self-advocacy via stuttering disclosure in CWS.

Abstract
Purpose Adults who stutter (AWS) have increased risk of comorbid social anxiety about speaking in social contexts. AWS also report experiencing embarrassment in different social situations; however, research has rarely been conducted on embarrassment and its relationship to social anxiety in AWS. Method AWS (N = 200) reported their level of embarrassment on four 10-point Likert items when speaking in four situational contexts: at home, to an individual important to them, in social groups, and at work. Participants were also assessed for sociodemographic, stuttering, and anxiety variables. Construct validity for the four embarrassment items was examined, the extent of embarrassment established in the four contexts as a function of age and sex, and the relationship of embarrassment to social anxiety evaluated. Results Evidence of acceptable construct validity and reliability is presented for the four embarrassment Likert items. Sixty-five percent of the sample experienced high levels of embarrassment when speaking in groups or at work, while 35.5% experienced high levels when speaking at home or to an individual important to them. Participants were significantly more embarrassed (p < .01) when speaking at work or when socializing in groups. Embarrassment was lowest when speaking in the home. Younger females were significantly more embarrassed when speaking at work or when socializing in groups. Those with high embarrassment scores on all four items were more likely to have elevated social anxiety scores (p < .001). Conclusion These preliminary results suggest that the assessment of situational embarrassment could be an important clinical measure that may help improve stuttering treatment outcomes that also target social anxiety.

Abstract
Purpose: Existing data stemming from investigations with the Speech Situation Checklist (SSC) have shown this standardised test to be a valid and reliable tool for assessing speech-related anxiety in children who stutter (CWS). The main purpose of this study was to compare Speech Situation Checklist-Emotional Reaction (SSC-ER) scores for Kannada-speaking children who do not stutter (CWNS) and CWS. In addition, the Speech Situation Checklist-Emotional Reaction in Kannada (SSC-ER-K) scores among different stuttering severity and age groups were compared in CWS.Method: The English version of the SSC-ER was forward-translated into Kannada and back-translated by the first author. SSC-ER-K was administered on 100 CWS and 275 CWNS aged between 7 and 14 years who were native speakers of the Kannada language. The severity of stuttering was estimated using the Stuttering Severity Instrument-fourth edition (SSI-4).Result: The results revealed that the SSC-ER-K scores of CWS were significantly higher in comparison with CWNS. CWS with moderate and severe degrees of stuttering had significantly higher scores when compared to those with a mild degree of stuttering. Furthermore, the older CWS (11-14 years) had significantly higher scores compared to the younger CWS (7-10 years). In addition, the SSC-ER-K appears to be a reliable self-report test. The above findings suggest the presence of significantly increased speech-related anxiety in CWS. Also, as age and severity of stuttering increased so did the level of their speech-related anxiety.Conclusion: The SSC-ER-K is a useful tool in the assessment of negative emotional reaction to specific speech situations in Kannada CWS and can assist speech-language pathologists in addressing speech-situation specific anxiety during treatment.

Abstract
PURPOSE This study estimated the treatment outcomes of a behavioral stuttering therapy program that blended a combination of intensive face-to-face therapy with telepractice-based follow-up therapy. METHOD A total of 17 participants (mean age = 22 years) who stutter participated in the program, preceded by an extended baseline period. The participants completed a series of assessments conducted over multiple time points, spanning a total of 42 weeks. Growth curve modeling was used to analyze the changes participants experienced in the frequency of stuttering, stuttering severity, communication attitudes, and quality of life. RESULTS The participants demonstrated stability throughout the extended baseline period, and experienced positive outcomes from the intensive program and the gains in communication attitudes and quality of life were largely maintained with weekly follow-up telepractice sessions. However, stuttering frequency and severity increased when the telepractice follow-up session frequency transitioned to a biweekly basis. Neither gender nor age group predicted the treatment outcomes for frequency or severity of stuttering. Gender-based differences were found for the treatment outcomes of specific self-report measures, with male participants having demonstrated a greater proportional decline on their standard scores, relative to female participants. Outcomes were similar for both adolescents and adults. CONCLUSIONS Participants attending the intensive stuttering therapy program experienced positive and significant changes in their speech, attitudes toward communication, and overall quality of life, which were maintained over time with structured, weekly telepractice follow-up sessions.

Abstract
Purpose Stuttering is characterized by intermittent speech disfluencies, which are dramatically reduced when speakers synchronize their speech with a steady beat. The goal of this study was to characterize the neural underpinnings of this phenomenon using functional magnetic resonance imaging. Method Data were collected from 16 adults who stutter and 17 adults who do not stutter while they read sentences aloud either in a normal, self-paced fashion or paced by the beat of a series of isochronous tones ("rhythmic"). Task activation and task-based functional connectivity analyses were carried out to compare neural responses between speaking conditions and groups after controlling for speaking rate. Results Adults who stutter produced fewer disfluent trials in the rhythmic condition than in the normal condition. Adults who stutter did not have any significant changes in activation between the rhythmic condition and the normal condition, but when groups were collapsed, participants had greater activation in the rhythmic condition in regions associated with speech sequencing, sensory feedback control, and timing perception. Adults who stutter also demonstrated increased functional connectivity among cerebellar regions during rhythmic speech as compared to normal speech and decreased connectivity between the left inferior cerebellum and the left prefrontal cortex. Conclusions Modulation of connectivity in the cerebellum and prefrontal cortex during rhythmic speech suggests that this fluency-inducing technique activates a compensatory timing system in the cerebellum and potentially modulates top-down motor control and attentional systems. These findings corroborate previous work associating the cerebellum with fluency in adults who stutter and indicate that the cerebellum may be targeted to enhance future therapeutic interventions.

Real and virtual classrooms can trigger the same levels of stuttering severity ratings and anxiety in school-age children and adolescents who stutter. JOURNAL OF FLUENCY DISORDERS 2021; 68:105830. [PMID: 33662867 DOI: 10.1016/j.jfludis.2021.105830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 01/30/2021] [Accepted: 02/09/2021] [Indexed: 06/12/2023]
Abstract
PURPOSE Many school-age children and adolescents who stutter experience the fear of public speaking. Treatment implications include the need to address this problem. However, it is not always possible to train repeatedly in front of a real audience. The present study aimed to assess the relevance of using a virtual classroom in clinical practice with school-age children and adolescents who stutter. METHODS Ten children and adolescents who stutter (aged 9-17 years old) had to speak in three different situations: in front of a real audience, in front of a virtual class and in an empty virtual apartment using a head-mounted display. We aimed to assess whether the self-rated levels of anxiety while speaking in front of a virtual audience reflect the levels of anxiety reported while speaking in front of a live audience, and if the stuttering level while speaking to a virtual class reflects the stuttering level while speaking in real conditions. RESULTS Results show that the real audience creates higher anticipatory anxiety than the virtual class. However, both the self-reported anxiety levels and the stuttering severity ratings when talking in front of a virtual class did not differ from those observed when talking to a real audience, and were significantly higher than when talking in an empty virtual apartment. CONCLUSION Our results support the feasibility and relevance of using a virtual classroom to expose school-age children and adolescents who stutter to a feared situation during cognitive behavioral therapy targeting the fear of public speaking.

Bauerly KR, Jones RM. The impact of self-reported levels of anxiety on respiratory sinus arrhythmia levels in adults who stutter. JOURNAL OF COMMUNICATION DISORDERS 2021; 90:106084. [PMID: 33611109 DOI: 10.1016/j.jcomdis.2021.106084] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 01/11/2021] [Accepted: 01/11/2021] [Indexed: 06/12/2023]
Abstract
PURPOSE This study investigated whether subjective levels of anxiety predict respiratory sinus arrythmia (RSA) levels in adults who stutter (AWS) compared to (ANS) during baseline and social stress situations. METHODS Participants were eight AWS and 10 ANS who performed a modified version of the Trier Social Stress Test (TSST-M). For this, participants were required to prepare and deliver a 5-minute speech and perform a nonword reading task in front of what was perceived as a group of professionals trained in public speaking. Measures of respiratory sinus arrhythmia (RSA) were calculated for baseline and TSST-M conditions. Participants also completed the State-Trait Anxiety Inventory (STAI), both the trait (STAI-T) and state (STAI-S) portion, which served as subjective anxiety ratings. Univariate analyses of variances (UNIANOVA) were used to assess the effects of the STAI-T and STAI-S anxiety on respiratory sinus arrhythmia (RSA) levels at pre-stress and TSST-M conditions. RSA, an index of parasympathetic nervous system activity, is considered to be a measure of emotional regulation. The strength of the effects of STAI-T and STAI-S on RSA levels was evaluated with the unstandardized coefficients for each group separately. RESULTS Results showed a significant difference between groups for the effects of STAI-T on RSA values for the pre-stress nonword reading task. No other significant differences were found between groups for the pre-stress or TSST-M conditions. Slope estimates showed that STAI-T was a significant predictor of RSA values for pre-stress speaking conditions for the AWS but not ANS. No significant fixed effects or interaction effects were found for the STAI-S and RSA levels in the AWS or ANS. Nor were there significant effects of STAI-T on RSA levels in the AWS or ANS for TSST-M conditions. Descriptive analysis revealed the effects found in the AWS during pre-stress conditions were attributed to a subgroup of AWS who reported low self-reports of anxiety (i.e. STAI-T) and high levels of emotional regulation (i.e. RSA) across social stress conditions. DISCUSSION Low self-reported STAI-T scores simultaneous with high RSA levels in some AWS may reflect a self-regulatory strategy adapted in response to chronic, daily stress associated with stuttering.
