[PMID: 38493582 DOI: 10.1016/j.jfludis.2024.106040] [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: 05/12/2023] [Revised: 12/25/2023] [Accepted: 02/11/2024] [Indexed: 03/19/2024]
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 Stuttering is a speech condition that can have a major impact on a person's quality of life. This descriptive study aimed to identify subgroups of people who stutter (PWS) based on stuttering burden and to investigate differences between these subgroups on psychosocial aspects of life. METHOD The study included 618 adult participants who stutter. They completed a detailed survey examining stuttering symptomatology, impact of stuttering on anxiety, education and employment, experience of stuttering, and levels of depression, anxiety, and stress. A two-step cluster analytic procedure was performed to identify subgroups of PWS, based on self-report of stuttering frequency, severity, affect, and anxiety, four measures that together inform about stuttering burden. RESULTS We identified a high- (n = 230) and a low-burden subgroup (n = 372). The high-burden subgroup reported a significantly higher impact of stuttering on education and employment, and higher levels of general depression, anxiety, stress, and overall impact of stuttering. These participants also reported that they trialed more different stuttering therapies than those with lower burden. CONCLUSIONS Our results emphasize the need to be attentive to the diverse experiences and needs of PWS, rather than treating them as a homogeneous group. Our findings also stress the importance of personalized therapeutic strategies for individuals with stuttering, considering all aspects that could influence their stuttering burden. People with high-burden stuttering might, for example, have a higher need for psychological therapy to reduce stuttering-related anxiety. People with less emotional reactions but severe speech distortions may also have a moderate to high burden, but they may have a higher need for speech techniques to communicate with more ease. Future research should give more insights into the therapeutic needs of people highly burdened by their stuttering. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.25582980.

Abstract
PURPOSE Differences in inhibitory control and cognitive flexibility between children who stutter (CWS) and children who do not stutter (CWNS) have been previously demonstrated. The aim of the current study was to investigate whether the previously reported inhibitory control- and cognitive flexibility-related performance costs for CWS are associated with the number of speech disfluencies that they produce. METHOD Participants were 19 CWS (Mage = 7.58 years, range: 6.08-9.17) and 19 CWNS matched on age and gender (Mage = 7.58 years, range: 6.08-9.33). Gamma regression models were used to investigate possible associations between performance costs in speed and accuracy measured during a computer task evaluating inhibitory control and cognitive flexibility and the number of speech disfluencies during video-recorded speech samples (story retelling and casual conversation). RESULTS Two significant interactions were observed. For both inhibitory control and cognitive flexibility, we identified a significant group and inhibitory control/cognitive flexibility performance-cost interaction in stuttering-like disfluencies (SLDs), indicating that the performance-cost effects on SLD production were significantly higher in the CWS group, compared to the CWNS group. CONCLUSIONS CWS with reduced inhibitory control or cognitive flexibility produce more SLDs, but not other disfluencies. These results are partly in line with some previous findings in nonstuttering and stuttering populations linking inhibitory control and cognitive flexibility weaknesses to the production of speech disfluencies.

Abstract
PURPOSE Frustration is an emotion often clinically reported by persons who stutter. So far, mainly questionnaire-based studies have reported findings related to increased frustration or decreased frustration tolerance. The aim of this preliminary study was to determine possible group differences between children who stutter (CWS) and children who do not stutter (CWNS) using a behavioral experimental task, as well as to evaluate possible associations with the frequency, duration, and physical concomitants of stuttering disfluencies. METHOD Participants were 13 CWS (mean age = 6;05 years) and 13 CWNS (mean age = 6;06 years), matched on age (±4 months) and gender. Frustration tolerance was assessed by the Delay Frustration task. This task includes normal delay, short delay, and long delay trials. Responses during long delay trials provide an indication of frustration tolerance and were recorded across time intervals during the response window. RESULTS CWS, compared to CWNS, responded more frequently during the long delay trials, which is indicative of higher delay frustration. The variation in responding across time within intervals was similar for both groups. Decreased frustration tolerance was associated with increased duration of stuttered disfluencies and of physical concomitants. CONCLUSIONS In general, the current findings seem to provide support for earlier theoretical conceptualizations about the role of emotional reactivity in the development of stuttering.

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 The Fifth Croatia Stuttering Symposium of 2022 continued the Fourth Croatia Stuttering Symposium 2019 theme of the connection between research and clinical practice. At the 2022 Symposium, there were 145 delegates from 21 countries. This paper documents the contents of the third of three Symposium modules. METHODS The module topic was mental health and early stuttering, and that pre-schoolers who stutter are at risk of developing mental health issues. A clinical situation was considered where a parent of a 3-year-old child asked a clinician what the early signs of mental health issues might be for a child who stutters. RESULTS A distinguished scholar presented a 5-minute video interpretation of research about this topic. Three master clinicians then each presented a 2-minute video demonstration of how that research might be applied in a clinical situation. Following that, the convenors moderated a discussion between the distinguished scholar, master clinicians, and delegates regarding the research and how it applies to clinical practice.

Abstract
PURPOSE People who stutter often experience significant adverse impact related to stuttering. However, it is unclear how adverse impact develops in children who stutter (CWS) and whether there are protective factors that may mitigate its development. This study examined the relationship between resilience, a potentially protective factor, and stuttering's adverse impact in CWS. Resilience comprises external factors, such as family support and access to resources as well as personal attributes, making it a comprehensive protective factor to explore. METHOD One hundred forty-eight CWS aged 5-18 years completed the age-appropriate version of the Child and Youth Resilience Measure (CYRM) and the Overall Assessment of the Speaker's Experience of Stuttering. Parents completed a caregiver version of the CYRM and a behavioral checklist for their child. The adverse impact of stuttering was modeled as a function of resilience (external, personal, and total), controlling for child age and behavioral checklist score. We also estimated correlations between child-report and parent-report CYRM measures to assess rater agreement. RESULTS Children reporting greater external, personal, or total resilience were more likely to experience lower degrees of adverse impact related to their stuttering. We documented stronger correlations between younger child and parent ratings of resilience and weaker correlations between older child and parent ratings. CONCLUSIONS These results yield valuable insight into the variability of adverse impact experienced by CWS and offer empirical support for strength-based speech therapy approaches. We discuss the factors that contribute to a child's resilience and provide practical suggestions for how clinicians can incorporate resilience-building strategies into intervention for children experiencing significant adverse impact from their stuttering.

Abstract
PURPOSE This study evaluated the relationship between emotional regulation (ER) and adverse impact related to stuttering across the developmental spectrum, in preschool and school-age children, adolescents, and adults who stutter. An additional aim examined how these variables relate to the ways that individuals approach speaking (i.e., their agreement on whether their goal is to speak fluently). METHOD Participants were the parents of 60 preschoolers and younger school-age children (ages 3-9 years), 95 school-age children and adolescents who stutter (ages 7-18 years), and 180 adults who stutter (ages 18-81 years). All participants completed surveys with age-appropriate measures examining ER and the adverse impact of stuttering. Older children and adults who stutter also answered questions regarding their goals when speaking. Multiple regression and ordinal logistic regression were used to examine relationships among ER, adverse impact related to stuttering, and goal when speaking. RESULTS In preschool children, adverse impact was significantly predicted by a parent-reported measure of ER skills; in school-age children and adults, adverse impact was significantly predicted by measures of the ER strategies cognitive reappraisal (CR) and expressive suppression. Less frequent use of CR by adults was significantly associated with an increased likelihood of having "not stuttering" as a goal when speaking. Differences in the significance and magnitude of these relationships were found across the life span. DISCUSSION For both children and adults who stutter, ER is a significant factor related to the adverse impact of stuttering; the relationship between ER and adverse impact may change over development. Accounting for individual differences in ER can improve understanding of why a person copes with stuttering in the ways they do, and this has notable implications for individualizing intervention for both children and adults who stutter.

Abstract
PURPOSE The purpose of this study was to explore how well a cumulative risk approach, based on empirically supported predictive factors, predicts whether a young child who stutters is likely to develop persistent developmental stuttering. In a cumulative risk approach, the number of predictive factors indicating a child is at risk to develop persistent stuttering is evaluated, and a greater number of indicators of risk are hypothesized to confer greater risk of persistent stuttering. METHOD We combined extant data on 3- to 5-year-old children who stutter from two longitudinal studies to identify cutoff values for continuous predictive factors (e.g., speech and language skills, age at onset, time since onset, stuttering frequency) and, in combination with binary predictors (e.g., sex, family history of stuttering), used all-subsets regression and receiver operating characteristic curves to compare the predictive validity of different combinations of 10 risk factors. The optimal combination of predictive factors and the odds of a child developing persistent stuttering based on an increasing number of factors were calculated. RESULTS Based on 67 children who stutter (i.e., 44 persisting and 23 recovered) with relatively strong speech-language skills, the predictive factor model that yielded the best predictive validity was based on time since onset (≥ 19 months), speech sound skills (≤ 115 standard score), expressive language skills (≤ 106 standard score), and stuttering severity (≥ 17 Stuttering Severity Instrument total score). When the presence of at least two predictive factors was used to confer elevated risk to develop persistent stuttering, the model yielded 93% sensitivity and 65% specificity. As a child presented with a greater number of these four risk factors, the odds for persistent stuttering increased. CONCLUSIONS Findings support the use of a cumulative risk approach and the predictive utility of assessing multiple domains when evaluating a child's risk of developing persistent stuttering. Clinical implications and future directions are discussed.

Abstract
PURPOSE Behavior and temperament (e.g., emotional reactivity, self-regulation) have been considered relevant to stuttering and its developmental course, but the direction of this relation is still unknown. Knowledge of behavior difficulties and temperament in childhood stuttering can improve screening and intervention. The current study examined both directions of the relationship between stuttering and behavior difficulties and temperament and between persistent stuttering and behavior difficulties and temperament across childhood. METHOD This study was embedded in the Generation R Study, a population-based cohort from fetal life onward in the Netherlands. We analyzed data from 145 children (4.2%) with a history of stuttering (118 recovered, 27 persistent) and 3,276 children without such a history. Behavior and temperament were repeatedly assessed using parental questionnaires (Child Behavior Checklist) and Infant/Child Behavior Questionnaire between 0.5 and 9 years of age. Multiple logistic and linear regression analyses were performed. RESULTS Six-month-old children who were less able to "recover from distress," indicating poor self-regulation, were more likely to develop persistent stuttering later in childhood (odds ratio = 2.05, 95% confidence interval (CI) [1.03, 4.05], p = .04). In the opposite direction, children with a history of stuttering showed more negative affectivity (β = 0.19, 95% CI [0.02, 0.37], p = .03) at 6 years of age than children without such a history. Stuttering persistence was associated with increased internalizing behaviors (β = 0.38, 95% CI [0.03, 0.74], p = .04) and higher emotional reactivity (β = 0.53, 95% CI [0.09, 0.89], p = .02) at the age of 9 years. CONCLUSIONS Behavior and temperament were associated with stuttering persistency-seemingly as both predictor and consequence-but did not predict a history of stuttering. We suggest that children who persist in stuttering should be carefully monitored, and if behavioral or temperamental problems appear, treatment for these problems should be offered.

Abstract
PURPOSE The purpose of this study was to use psychological measures of pre-schoolers who stutter and their parents to inform causal theory development and influence clinical practices. This was done using data from a substantive clinical cohort of children who received early stuttering treatment. METHOD The cohort (N = 427) comprised parents and their children who were treated with the Lidcombe Program, the Westmead Program, and the Oakville Program. The study incorporated demographic information, stuttering severity, and child and parent psychological measures prior to treatment. RESULT The cohort revealed nothing unusual about behavioural and emotional functioning, or the temperaments, of pre-school children that would influence treatment, be targeted during treatment, or influence causal theory development. However, a third of parents were experiencing moderate to high life stressors at the time of seeking treatment, and half the parents failed first-stage screening for Anankastic Personality Disorder. CONCLUSION The present results are consistent with a number of previous reports that showed that the population of pre-schoolers who stutter have no unusual psychological profiles. Hence, these results suggest that the association between mental health and stuttering later in life is a consequence of the disorder rather than being a part of its cause. The finding of the life stress of parents who seek stuttering treatment for pre-school children has potential clinical importance and warrants further investigation. Further psychological research is required about parents of pre-school children who stutter, because half the parents in the cohort failed the screener for Anankastic Personality Disorder. This is of interest because a previous study associated screening failure for another personality disorder (Impulsive Personality Disorder) with treatment dropout for early childhood stuttering.

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 The purpose of the present study was to examine the degree to which certain temperament constructs predict individual differences in three types of behavioral responses to anticipation among children and adults who stutter (CWS and AWS, respectively): avoidance, physical change, and approach. METHODS Participants included 64 CWS (9- to 17-years-old) and 54 AWS (18- to 50-years-old) who completed an online survey package including a temperament questionnaire (Early Adolescent Temperament Questionnaire-Revised for the CWS; Adult Temperament Questionnaire for the AWS) and the Stuttering Anticipation Scale. The data were analyzed separately for CWS and AWS using multivariate multiple regressions to assess how each temperament construct predicted avoidance, physical change, and approach responses to anticipation. RESULTS CWS who reported higher levels of shyness were more likely to engage in avoidant behavioral responses when they anticipate an upcoming moment of stuttering. AWS who reported higher levels of orienting sensitivity were more likely to engage in avoidant behavioral responses when they anticipate an upcoming moment of stuttering. No temperament constructs predicted physical change or approach responses to anticipation among either age group. CONCLUSION Specific aspects of temperament appear to be linked to the degree that CWS and AWS engage in avoidant behavioral responses to stuttering anticipation. These findings support the continued study of how individual differences impact the internal experience and outward manifestation of stuttering behaviors.

Abstract
Purpose Recent research has shown that some school-age children who stutter may have speech-related anxiety. Given this, speech-language pathologists require robust measures to assess the psychological effects of stuttering during the school-age years. Accordingly, this systematic review aimed to explore available measures for assessing the psychological impacts of stuttering in young school-age children and to examine their measurement properties. Method The systematic search protocol was registered with PROSPERO (ID: 163181). Seven online databases, in addition to manual searching and screening of reference lists, were used to identify appropriate measures for the population of children who stutter aged 7-12 years. The first two authors independently assessed the measures using the quality appraisal tool described by Terwee et al. (2007). Results Despite the comprehensive search strategy, only six measures were identified for quality appraisal. No assessment tool was found to possess adequate measurement properties for the eight assessed domains: content validity, internal consistency, construct validity, reproducibility, reliability, responsiveness, floor and ceiling effects, and interpretability. No measure had clear evidence of responsiveness to clinical change. Based on the criterion defined by the Terwee et al. (2007) appraisal tool, the Communication Attitude Test and the Overall Assessment of the Speaker's Experience of Stuttering for School-Age Children received the highest number of ratings in support of their measurement properties. Conclusions The results highlight a lack of available measures in this domain and poor practices in developing and testing measurement instruments. To ensure that clinicians and researchers are equipped with sound measures to meet the mental health needs of this vulnerable population, further research to establish resources is needed.

Abstract
Purpose This study compared attention control and flexibility in school-age children who stutter (CWS) and children who do not stutter (CWNS) based on their performance on a behavioral task and parent report. We used a classic attention-shifting paradigm that included manipulations of task goals and timing to test effects of varying demands for flexibility on switching accuracy and speed. We also examined associations between task performance, group, and relevant aspects of temperament. Method Participants included 33 children (15 CWS, 18 CWNS) between 8 and 11 years of age. Children sorted stimuli that differed on two dimensions (color and shape) based on sorting rules that varied from block to block or trial to trial. Timing manipulations included intervals of 200-, 600-, or 1,200-ms durations for critical trial components. Temperament data were obtained via the Children's Behavior Questionnaire. Results All children showed expected performance costs in response to block and trial manipulations; however, CWS were more affected by task conditions that increased demands for cognitive flexibility. Effects of interval durations also differed by group. Factor scores on the Children's Behavior Questionnaire indicated differences in effortful control between groups; however, this aspect of temperament did not mediate between-groups differences in switching performance. Conclusions Findings suggest that stuttering continues to be associated with differences in attention control and flexibility beyond the preschool years. Further research is needed to clarify how these cognitive processes shape the development of stuttering throughout childhood.

Abstract
Purpose The goal of this study was to evaluate possible associations between child- and mother-reported temperament, stuttering severity, and child-reported impact of stuttering in school-age children who stutter. Method Participants were 123 children who stutter (94 boys and 29 girls) who were between 9;0 and 14;10 (years;months) and their mothers. Temperament was assessed with the revised child and parent version of the Early Adolescent Temperament Questionnaire-Revised (Ellis & Rothbart, 2001). The Overall Assessment of the Speaker's Experience of Stuttering (Yaruss & Quesal, 2006) was used to evaluate the stuttering impact. Results Child- and mother-reported Early Adolescent Temperament Questionnaire-Revised temperament factors correlated moderately. No statistically significant associations were found between temperament and stuttering severity. The temperament factors of Surgency (both child- and mother-reported) and Negative Affect (only child-reported) correlated moderately with the Overall Impact and several subsections (i.e., Speaker's Reactions, Daily Communication, and/or Quality of Life) of the Overall Assessment of the Speaker's Experience of Stuttering. Conclusions More extraverted and less fearful/shy children experience a lower overall impact of their stuttering. Children with higher levels of irritability and frustration experience a higher overall impact of their stuttering. Since children's ratings of temperament were more sensitive to these associations than mothers, this study supports the inclusion of child-reported temperament questionnaires in future research.

Abstract
Purpose: This experimental cross-sectional research study examined the emotional reactivity and emotion regulation in preschool-age children who do (CWS) and do not stutter (CWNS) by assessing their psychophysiological response during rest and while viewing pictures from the International Affective Picture System (Lang et al., 2008). Method: Participants were 18 CWS (16 boys and two girls; mean age 4 years, 5 months) and 18 age- and gender-matched CWNS. Participants' psychophysiological responses were measured during two baselines and two picture viewing conditions. Skin conductance level (SCL) and heart rate were measured to assess emotional reactivity. Respiratory sinus arrhythmia (RSA) was measured to assess emotional regulation. Participants' shyness and executive function were assessed via parent report and considered for their effects on participants' psychophysiological responses. Results: First, CWNS and CWS did not differ in their initial baseline SCL, heart rate, or RSA, but all participants had higher SCL and lower RSA in the second baseline, subsequent to the first challenge condition, compared to the first baseline. Second, during the challenge conditions, CWS did not differ from CWNS in their SCL, but showed a significantly higher heart rate than CWNS. Third, CWS exhibited a significantly lower RSA during the challenge conditions compared to CWNS. Lastly, the temperamental quality of shyness was associated with preschool-age children's SCL, such that participants who were rated higher in shyness had a higher SCL during the challenge conditions. Participants' executive function had a marginally significant effect on the RSA, such that the participants who had higher executive function composite scores exhibited lower RSA during the challenge conditions. Conclusions: Our findings suggest that CWS and CWNS did not differ in their emotional reactivity and emotional regulation abilities at rest. During challenge conditions, however, CWS tended to be more emotionally reactive, as indicated by a higher heart rate, and also employed more emotional regulation, indexed by a greater decrease in RSA, compared to CWNS. Preschool-age children's behavior is largely dominated by reactivity, but there is the emergence of regulation, which can help children adjust to various contextual demands. For CWS who are more emotionally reactive, regulatory skills may be particularly critical to their prognosis and treatment.

Abstract
PURPOSE Attention develops gradually from infancy to the preschool years and beyond. Exogenous attention, consisting of automatic responses to salient stimuli, develops in infancy, whereas endogenous attention, or voluntary attention, begins to develop later, in the preschool years. The purpose of this study was to examine (a) exogenous and endogenous attention in young children who stutter (CWS) and children who do not stutter (CWNS) through two conditions of a visual sustained selective attention task, and (b) visual short-term memory (STM) between groups within the context of this task. METHOD 42 CWS and 42 CWNS, ages 3;0-5;5 (years;months), were pair-matched in age, gender (31 males, 11 females per group), and socioeconomic status. Children completed a visual tracking task (Track-It Task; Fisher et al., 2013) requiring sustained selective attention and engaging exogenous and endogenous processes. Following each item, children were asked to recall the item they had tracked, as a memory check. RESULTS The CWS group demonstrated significantly less accuracy in overall tracking and visual memory for the tracked stimuli, compared to the CWNS group. Across groups, the children performed better in sustained selective attention when the target stimuli were more salient (the condition tapping both exogenous and endogenous attention) than when stimuli were less so (the condition tapping primarily endogenous processes). CONCLUSIONS Relative to peers, preschool-age CWS, as a group, display weaknesses in visual sustained selective attention and visual STM.

Abstract
PURPOSE To discuss clinical applications of research findings about temperament and early stuttering. METHOD A "1000-bytes" format (Onslow & Millard, 2012) was used to provide readers with contemporaneous observation of a "conversation" between the authors. The conversation is proceeded by a prologue and followed by concluding statements from each author. RESULTS One author contended that comprehensive, multidimensional assessment of temperament domains is essential during clinical management of early stuttering, and the results of that assessment are best incorporated into a multifactorial treatment approach. The other author contested that view, arguing that such an approach is not empirically justifiable at present. CONCLUSIONS The authors agree about the salience of research on temperament and early stuttering but have different perspectives about the topic when applied to providing health care for early stuttering.

Abstract
Purpose The purpose of this study was to investigate whether preschool-age children who stutter (CWS) were more likely to exhibit a temperamental trait of behavioral inhibition (BI), a correlate of shyness, than children who do not stutter (CWNS) and whether this temperamental trait affected preschool-age children's speech fluency and language complexity during a conversation with an unfamiliar adult. Method Sixty-eight preschool-age children (31 CWS, 37 CWNS) participated. The degree of BI was assessed by measuring the latency to their sixth spontaneous comment and the number of all spontaneous comments during a conversation with an unfamiliar examiner (following Kagan et al.'s [1987] methodology). Parent report of shyness from the Children's Behavior Questionnaire served as an indirect measure of BI. Children's language complexity was assessed by measuring their mean length of utterance and the number of words spoken. For CWS, the frequency of stuttering and the negative impact of stuttering were also assessed. Results First, we found no between-group differences in the degree of BI across the behavioral observation measures. However, CWS were rated shyer by parents than CWNS. Second, for CWS only, higher BI was associated with less complex utterances and fewer words spoken. Third, for CWS, higher BI was associated with fewer stuttered disfluencies produced. Conclusions This study provides empirical evidence that BI to the unfamiliar may have salience for childhood stuttering as it affected the quantity and quality of language spoken with an unfamiliar adult. Clinical implications of high BI for the assessment and treatment of preschool-age stuttering are discussed.

Abstract
PURPOSE This two-part (i.e., Study 1, Study 2) study investigated behavioral inhibition (BI) in preschool-age children who do (CWS) and do not (CWNS) stutter. The purpose of Study 1 was to develop the Short Behavioral Inhibition Scale (SBIS), a parent-report scale of BI. The purpose of Study 2 was to determine, based on the SBIS, differences in BI between CWS and CWNS, and associations between BI and CWS's stuttering frequency, stuttering severity, speech-associated attitudes, and stuttering-related consequences/reactions. METHOD Participants in Study 1 were 225 CWS and 243 CWNS with the majority of them being included in Study 2. In Study 2, a speech sample was obtained for the calculation of stuttering frequency and severity, and the parents of a subset of CWS completed the Communication Attitude Test for Preschool and Kindergarten Children Who Stutter (Vanryckeghem & Brutten, 2007), and the Test of Childhood Stuttering Disfluency-Related Consequences Rating Scale (Gillam, Logan, & Pearson, 2009). RESULTS Study 1 analyses indicated that SBIS is a valid and reliable tool whose items assess a single, relatively homogeneous construct. In Study 2, CWS exhibited greater mean and extreme BI tendencies than CWNS. Also CWS with higher, compared to CWS with lower, BI presented with greater stuttering frequency, more severe stuttering, greater stuttering-related consequences, and more negative communication attitudes (for CWS older than 4 years of age). CONCLUSION Findings were taken to suggest that BI is associated with early childhood stuttering and that the SBIS could be included as part of a comprehensive evaluation of stuttering.

Abstract
BACKGROUND Stuttering and speech sound disorder may co-occur during early childhood, although the exact rate of comorbidity in a community-cohort sample remains unknown. In isolation, both disorders have the potential for long-term negative effects. Comorbidity rates of 16%-46% reported in previous studies were based on parent report, speech-language therapist surveys, case file audits or direct observation studies from clinical samples. Rigorous methodology utilising a prospective, longitudinal community-cohort design is required to support these previous findings. AIMS First, to identify the proportion of children with comorbid stuttering and speech sound disorder at 4 years of age drawn from a community-cohort study. Second, to compare demographic and clinical features of this comorbid diagnosis group compared to children with no diagnosis of either disorder, or those with either disorder in isolation. METHODS & PROCEDURES Participants were drawn from a prospective, longitudinal community cohort study (the Early Language in Victoria Study) at 4 years of age (n = 1607). Demographic and clinical features for comparison were theoretically driven and included: gender, birth history, feeding status, speech and language status, family history of communication difficulties, maternal education, maternal vocabulary, maternal mental health and socioeconomic status. OUTCOMES & RESULTS Of the 160 children diagnosed with stuttering between 2 and 4 years of age, 6.88 % (n = 11) also had a speech sound disorder. Given the small sample size and number of comparisons performed, there was insufficient evidence to rule out that group differences observed were not simply due to chance. CONCLUSIONS & IMPLICATIONS The prevalence of comorbid stuttering and speech sound disorder was lower in a community cohort compared to that reported in clinical studies. Higher rates reported in clinical samples may be due to increased parental help-seeking behaviour when the two disorders co-occur. Subsequently, these children may present to clinics more frequently. Accurate representation of prevalence allows for population specific research on best practice assessment and intervention. Currently little is known about how best to manage this caseload, therefore more research is required in this area, including the determination of prognostic variables to provide efficient and effective management.

Abstract
The purpose of this study was to investigate the singular and joint contributions of speech-language dissociations and attention (i.e., distractibility and attention span) to stuttering chronicity. Method Participants, aged 3;0-4;11 (years;months) at an initial visit, were classified as persisting (n = 10; 9 boys), recovered (n = 32; 23 boys), and nonstuttering (n = 28; 19 boys) based on multiple speech and language evaluations spread across 2 years. The evaluations included assessments of articulation, receptive and expressive vocabulary, and omnibus receptive and expressive language. These measures were used to identify speech-language dissociations using a correlation-based statistical approach. Attentional characteristics, which included measures of distractibility and attention span, were based on parent report. Analyses investigated between-group differences related to dissociations and attentional characteristics as well as the relation between these indices. Results There were no significant between-group differences for the persisting and recovered groups on measures of speech-language dissociations; however, the recovered group was found to exhibit less optimal attention span than the persisting group. In addition, children with dissociations exhibited less optimal distractibility and attention spans at the final time point than children without dissociations. Conclusions Present results indicate that attention is related to both stuttering chronicity and the presence of speech-language dissociations; however, they do not support the notion that dissociations are associated with stuttering persistence. These results provide novel insights into the complex nature of the association between developmental stuttering, speech-language dissociations, and attention.

Abstract
Purpose The purpose of this study was to compare physiological indices of sympathetic nervous system arousal recorded during fluent and stuttered utterances in a preschool children who stutter (CWS). Method Twenty-two 4- to 5-year-old CWS participated in the experiment. We recorded children's skin conductance response amplitude and frequency, blood pulse volume amplitude, and pulse rate as they completed a picture description task. We then compared indices of phasic sympathetic arousal recorded during stuttered versus fluent utterances. In addition, children's communication attitudes were evaluated with a self-report measure. Results We detected significantly higher sympathetic arousal during stuttered utterances compared to fluent utterances. Specifically, we found larger skin conductance responses occurring at an increased frequency and decreased blood pulse volume amplitudes during stuttered speech. The behavioral measure indicated a negative communication attitude in only one-third of the participants. Conclusion Our findings suggest that preschool CWS may exhibit higher levels of sympathetic arousal during stuttered speech compared to when they are speaking fluently. We discuss the potential impact of increased sympathetic arousal on speech regulatory mechanisms in early childhood stuttering and present questions to guide future research.

Abstract
BACKGROUND iGlebe is a fully automated internet treatment program for adults who stutter that has been shown, in some cases, to reduce anxiety and effectively manage social anxiety disorder for many participants. No such automated internet treatment program exists for adolescents who stutter. AIMS The present paper reports a Phase I trial of an adolescent version of the adult program: iBroadway. METHODS & PROCEDURES Participants were 29 adolescents in the age range 12-17 years who were seeking cognitive-behaviour therapy (CBT) for anxiety associated with stuttering. The design was a non-randomized Phase I trial with outcome assessments at pre-treatment and immediately post-treatment after 5 months of access to the program. No contact by a clinical psychologist occurred during participant use of the program. Outcomes were a range of psychological, quality-of-life and stuttering severity measures. OUTCOMES & RESULTS The compliance rate for the seven iBroadway modules over 5 months was extremely favourable for internet CBT, at 52.4%. There was evidence of treatment effects for (1) the number of DSM-IV mental health diagnoses with the Diagnostic Interview Schedule for Children; (2) the Unhelpful Thoughts and Beliefs About Stuttering scale; (3) the Subjective Units of Distress Scale; and (4) parent-reported speech satisfaction. CONCLUSIONS & IMPLICATIONS Further development of iBroadway, the adolescent version of iGlebe, with Phase II trialling is warranted.

Abstract
BACKGROUND In our Dynamic Pathways, account, we hypothesized that childhood stuttering reflects an impairment in speech sensorimotor control that is conditioned by cognitive, linguistic, and emotional factors. The purpose of this study was to investigate potential differences in levels of sympathetic arousal during performance of speech and non-speech tasks between children who do and do not stutter. METHODS Seventy-two preschool-aged children participated in the study, 47 children who stutter (CWS; 38 boys) and 25 children who do not stutter (CWNS; 18 boys). We recorded skin conductance and blood pulse volume (BPV) signals, indices of sympathetic arousal, during higher/lower load speech tasks (structured sentence production and picture description) and non-speech tasks (jaw wagging and forceful blowing). We included a measure that reflects children's attitudes about their communication skills and a parent-report assessment of temperament. RESULTS We found no significant differences between preschool CWS and CWNS in phasic skin conductance response amplitude or frequency, BPV, and pulse rate for any of the experimental tasks. However, compared to CWNS, CWS had, on average, significantly higher skin conductance levels (SCL), indexing slowly changing tonic sympathetic activity, across both speech and non-speech experimental conditions. We found distinctive task-related profiles of sympathetic arousal in both groups of preschool children. Most children produced the highest levels of sympathetic arousal in the physically demanding blowing task rather than in speech, as seen in previous studies of adults. We did not find differences in temperament between the two groups of preschool children nor a relationship among behavioral indices of temperament and communication attitude and physiological measures of sympathetic arousal. CONCLUSION We did not find that atypically high, speech-related sympathetic arousal is a significant factor in early childhood stuttering. Rather, CWS had higher, on average, task-related tonic SCLs across speech and non-speech tasks. A relationship among behavioral measures of temperament and physiological measures of sympathetic arousal was not confirmed. Key questions for future experiments are how the typical coupling of sympathetic and speech sensorimotor systems develops over childhood and adolescence and whether task related developmental profiles follow a different course in children who continue to stutter.

Abstract
Purpose The study aim was to determine whether self-reported temperament traits differentiate adults who stutter (AWS) from adults who do not stutter (AWNS). Additionally, associations between temperament and stuttering frequency, and between temperament and quality of life impacts of stuttering, were investigated in AWS. Method Self-reported temperament traits were documented for 33 AWS and 43 AWNS using the Adult Temperament Questionnaire (ATQ; Evans & Rothbart, 2007). Quality-of-life impacts of stuttering were assessed using the Overall Assessment of the Speaker's Experience with Stuttering (Yaruss & Quesal, 2010). Stuttering frequency was calculated from 100-word monologue and reading samples. Results A between-groups difference in scores on the ATQ Positive Affect subscale was nominally significant (i.e., before correcting for multiple tests) and also approached statistical significance after Bonferroni correction. Positive Affect scores were lower for AWS, and the size of this trending effect was moderate. Within AWS, a statistically significant positive correlation was found between impact scores on the General Information section of the Overall Assessment of the Speaker's Experience with Stuttering and ATQ Frustration subscale scores after Bonferroni correction. No associations were detected between temperament traits and stuttering frequency. Conclusions Results reveal a nontrivial tendency for AWS to experience decreased positive affect compared to AWNS. In addition, increased frustration was found to be associated with reduced general knowledge about stuttering in AWS. Neither effect has been previously reported for adults or children who stutter. Finally, self-reported temperament traits were not found to vary with stuttering frequency in adults, consistent with previous results for AWS.

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

Abstract
Affecting 5% of all preschool-aged children and 1% of the general population, developmental stuttering-also called childhood-onset fluency disorder-is a complex, multifactorial neurodevelopmental disorder characterized by frequent disruption of the fluent flow of speech. Over the past two decades, neuroimaging studies of both children and adults who stutter have begun to provide significant insights into the neurobiological bases of stuttering. This review highlights convergent findings from this body of literature with a focus on functional and structural neuroimaging results that are supported by theoretically driven neurocomputational models of speech production. Updated views on possible mechanisms of stuttering onset and persistence, and perspectives on promising areas for future research into the mechanisms of stuttering, are discussed.

Abstract
PURPOSE Multifactorial explanations of developmental stuttering suggest that difficulties in self-regulation and weak attentional flexibility contribute to persisting stuttering. We tested this prediction by examining whether preschool-age children who stutter (CWS) shift their attention less flexibly than children who do not stutter (CWNS) during a modified version of the Dimension Card Change Sort (DCCS), a reliable measure of attention switching for young children. METHODS Sixteen CWS (12 males) and 30 children CWNS (11 males) participated in the study. Groups were matched on age (CWS: M=49.63, SD=10.34, range=38-80months; CWNS: M=50.63, SD=9.82, range=37-74months), cognitive ability, and language skills. All children completed a computer-based variation of the DCCS, in which they matched on-screen bivalent stimuli to response buttons based on rules that switched mid-task. RESULTS Results showed increased slowing for CWS compared to controls during the postswitch phase, as well as contrasting patterns of speed-accuracy tradeoff for CWS and CWNS as they moved from the preswitch to postswitch phase of the task. CONCLUSIONS Group differences in performance suggest that early stuttering may be associated with difficulty shifting attention efficiently and greater concern about errors. Findings are consistent with a growing literature indicating links between weak attentional control and persisting developmental stuttering.

Abstract
Aims Associations between stuttering in childhood and a broad spectrum of risk factors, associated factors and comorbidities were examined in two large epidemiological studies. Subtypes of stuttering were then identified based on latent class analysis (LCA). Methods Data were from two representative Swiss population samples: PsyCoLaus (N = 4,874, age 35–82 years) and the ZInEP Epidemiology Survey (N = 1,500, age 20–41 years). Associations between stuttering and sociodemographic characteristics, familial aggregation, comorbidity and psychosocial risk / associated factors were investigated in both samples. LCAs were conducted on selected items from people in both samples who reported having stuttered in childhood. Results Initial analyses linked early anxiety disorders, such as separation anxiety disorder and overanxious disorder, to stuttering (PsyCoLaus). ADHD was associated with stuttering in both datasets. In the analyses of risk / associated factors, dysfunctional parental relationships, inter-parental violence and further childhood adversities were mutual predictors of stuttering. Moreover, comorbidities were seen with hay fever, asthma, eczema and psoriasis (PsyCoLaus). Subsequent LCA identified an unspecific group of persons who self-reported that they stuttered and a group defined by associations with psychosocial adversities (ZINEP, PsyCoLaus) and atopic diseases (PsyCoLaus). Conclusions The two subtypes of developmental stuttering have different risk / associated factors and comorbidity patterns. Most of the factors are associated with vulnerability mechanisms that occur early in life and that have also been linked with other neurodevelopmental disorders. Both psychosocial and biological factors appear to be involved in the etiopathogenesis of stuttering.

Abstract
PURPOSE This study presents a meta-analytic review of differences in verbal short-term memory, inhibition, and attention between children who stutter (CWS) and children who do not stutter (CWNS). METHOD Electronic databases and reference sections of articles were searched for candidate studies that examined verbal short-term memory, inhibition, and attention using behavioral and/or parent report measures. Twenty-nine studies met the eligibility criteria, which included, among other things, children between the ages of 3 and 18 years and the availability of quantitative data for effect size calculations. Data were extracted, coded, and analyzed, with the magnitude of the difference between the 2 groups of children being estimated using Hedge's g (Hedges & Olkin, 1985). RESULTS Based on the random-effects model (Hunter & Schmidt, 2004), findings revealed that CWS scored lower than CWNS on measures of nonword repetition (Hedges' g = -0.62), particularly at lengths of 2 and 3 syllables (Hedges' g = -0.62 and - 0.50, respectively), and forward span (Hedges' g = -0.40). Analyses further revealed that the parents of CWS rated their children as having weaker inhibition (Hedges' g = -0.44) and attentional focus/persistence (Hedges' g = -0.36) skills than the parents of CWNS, but there were no significant differences between CWS and CWNS in behavioral measures of inhibition and attention. CONCLUSION The present findings were taken to suggest that cognitive processes are important variables associated with developmental stuttering.

Abstract
PURPOSE This study sought to determine the cortical associates of emotional reactivity and emotion regulation (as indexed by the amplitude of evoked response potentials [ERP]) in young children who do and do not stutter during passive viewing of pleasant, unpleasant and neutral pictures. METHOD Participants were 17 young children who stutter and 22 young children who do not stutter (between 4 years 0 months to 6 years 11 months). The dependent measures were (1) mean amplitude of late positive potential (LPP, an ERP sensitive to emotional stimuli) during passive (i.e., no response required) picture viewing and directed reappraisal tasks and (2) emotional reactivity and regulation related scores on caregiver reports of young children's temperament (Children's Behavior Questionnaire, CBQ). RESULTS Young CWS, when compared to CWNS, exhibited significantly greater LPP amplitudes when viewing unpleasant pictures, but no significant between-group difference when viewing pleasant pictures and during the emotion regulation condition. There were, however, for CWS, but not CWNS, significant correlations between temperament-related measures of emotion and cortical measures of emotional reactivity and regulation. CONCLUSIONS Findings provide further empirical support for the notion that emotional processes are associated with childhood stuttering, and that CWS's inherent temperamental proclivities need to be taken into account when empirically studying or theorizing about this association.

Abstract
PURPOSE This study investigated the possible association of emotional processes and articulation rate in pre-school age children who stutter and persist (persisting), children who stutter and recover (recovered) and children who do not stutter (nonstuttering). METHODS The participants were ten persisting, ten recovered, and ten nonstuttering children between the ages of 3-5 years; who were classified as persisting, recovered, or nonstuttering approximately 2-2.5 years after the experimental testing took place. The children were exposed to three emotionally-arousing video clips (baseline, positive and negative) and produced a narrative based on a text-free storybook following each video clip. From the audio-recordings of these narratives, individual utterances were transcribed and articulation rates were calculated. RESULTS Results indicated that persisting children exhibited significantly slower articulation rates following the negative emotion condition, unlike recovered and nonstuttering children whose articulation rates were not affected by either of the two emotion-inducing conditions. Moreover, all stuttering children displayed faster rates during fluent compared to stuttered speech; however, the recovered children were significantly faster than the persisting children during fluent speech. CONCLUSION Negative emotion plays a detrimental role on the speech-motor control processes of children who persist, whereas children who eventually recover seem to exhibit a relatively more stable and mature speech-motor system. This suggests that complex interactions between speech-motor and emotional processes are at play in stuttering recovery and persistency; and articulation rates following negative emotion or during stuttered versus fluent speech might be considered as potential factors to prospectively predict persistence and recovery from stuttering.

JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2017; 60:1211-1222. [PMID: 28418529 DOI: 10.1044/2016_jslhr-s-16-0035] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2016] [Accepted: 10/27/2016] [Indexed: 06/07/2023]
Abstract
PURPOSE To examine if a community sample of 11-year-old children with persistent stuttering have higher anxiety than children who have recovered from stuttering and nonstuttering controls. METHOD Participants in a community cohort study were categorized into 3 groups: (a) those with persistent stuttering, (b) those with recovered stuttering, and (c) nonstuttering controls. Linear regression modeling compared outcomes on measures of child anxiety and emotional and behavioral functioning for the 3 groups. RESULTS Without adjustment for covariates (unadjusted analyses), the group with persistent stuttering showed significantly increased anxiety compared with the recovered stuttering group and nonstuttering controls. The group with persistent stuttering had a higher number of children with autism spectrum disorder and/or learning difficulties. Once these variables were included as covariates in subsequent analysis, there was no difference in anxiety, emotional and behavioral functioning, or temperament among groups. CONCLUSION Although recognized to be associated with stuttering in clinical samples, anxiety was not higher in school-age children who stutter in a community cohort. It may be that anxiety develops later or is less marked in community cohorts compared with clinical samples. We did, however, observe higher anxiety scores in those children who stuttered and had autism spectrum disorder or learning difficulties. Implications and recommendations for research are discussed.

Abstract
PURPOSE The purpose of this study was to ascertain if there is an association between stuttering severity and behaviors and the expression of temperament characteristics, including precursors of anxiety. METHOD We studied temperament characteristics of a prospectively recruited community cohort of children who stutter (N = 173) at ages 3, 4, and 6 years using the Short Temperament Scale STS (Prior, Sanson, Smart & Oberklaid, 2000). RESULTS Six of 131 statistical tests of association between stuttering severity and behaviors and temperament traits were statistically significant at the 5% level, which was no more than expected by chance alone. CONCLUSIONS On the basis of parent responses to the STS, preschoolers who exhibited different levels of stuttering severity and behaviors did not generally express temperament traits differently from one another. Stuttering severity and stuttering behaviors were not associated with the precursors of anxiety. Overall, taking multiple tests into consideration, results show little evidence of association between stuttering severity and temperament up to 4 years of age or between stuttering behaviors and temperament up to 6 years of age.

Abstract
PURPOSE The purpose of this study is to compare the health-related quality of life (HrQoL) of preschool children who stutter (CWS) and a reference population of children who do not stutter, and to evaluate the association between stuttering severity and HrQoL. METHODS Baseline data were used from 197 children participating in a multicenter Randomized Clinical Trial in the Netherlands. Information on stuttering severity and time since onset (TSO) of stuttering was obtained from the baseline evaluation by speech- and language therapists. Stuttering severity was measured using the SSI-3. HrQoL was assessed using proxy versions of two Child Health Questionnaires (ITQOL-97 and CHQ-PF28), the Health Utility Index 3 (HUI3) and the EuroQoL EQ-VAS (EQ-VAS). RESULTS While the outcomes on the EQ-VAS and the HUI3 showed that the HrQoL of CWS is slightly poorer than that of the Dutch reference population, results on the different dimensions of the CHQ-instruments did not reveal any difference in scores between stuttering children and reference groups. Within the group of CWS, two ITQOL-97 and four CHQ-PF28 scales showed statistically different scores for children in different SSI stuttering severity or TSO categories. However, the effect sizes showed that these differences were so small that they could be considered negligible. CONCLUSION The results of this study do not reveal a diminished HrQoL for preschool CWS. Future research should include a larger cohort of children with severe stuttering, study the longitudinal course of HrQoL and incorporate additional parameters such as the characteristics of the child and his environment. EDUCATIONAL OBJECTIVES The reader will be able to: (a) summarize the current evidence base on HrQoL in people who stutter; (b) describe the HrQoL of preschool CWS on different HrQoL measures; (c) describe the relationship between stuttering severity and HrQoL in preschool CWS.
