Winters KL, Byrd CT. Caregiver Predictions of Their 3- to 6-Year-Old Child Who Stutters' Communication Attitude. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2024; 67:2086-2105. [PMID: 38889195 PMCID: PMC11253804 DOI: 10.1044/2024_jslhr-23-00662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 03/11/2024] [Accepted: 04/24/2024] [Indexed: 06/20/2024]
Abstract
PURPOSE Caregivers share critical insight during their child's stuttering evaluation; yet, there have been no empirical studies evaluating whether caregivers provide similar accounts of their 3- to 6-year-old child's communication attitude compared to their child's self-report. This study examined caregiver- and child-reported communication attitude and assessed potential moderators of more comparable caregiver and child ratings (i.e., caregiver confidence, caregiver-child conflict, observer-rated stuttering severity). METHOD One hundred thirteen children who stutter ages 3 through 6 years and a primary caregiver were recruited from clinical settings across the United States. Children completed the Communication Attitude Test for Preschool and Kindergarten Children Who Stutter (KiddyCAT) and three speaking samples, which were recorded to assess observer-rated stuttering severity using the Stuttering Severity Instrument-Fourth Edition. Caregivers predicted their child's communication attitude (C-KiddyCAT) and provided a confidence rating for their prediction. Caregivers also rated caregiver-child conflict using the Child-Parent Relationship Scale-Short Form (CPRS-SF). Multiple regression was used to (a) evaluate whether caregiver C-KiddyCAT scores predicted child KiddyCAT scores and (b) assess potential moderators of the relationship between C-KiddyCAT and KiddyCAT scores. RESULTS Caregiver ratings of their child's communication attitude (C-KiddyCAT) predicted child communication attitude ratings (KiddyCAT). A significant interaction between caregiver-child conflict (CPRS-SF) and caregiver ratings of their child's communication attitude (C-KiddyCAT) suggested caregiver-child conflict changed the underlying relationship between C-KiddyCAT and KiddyCAT scores, such that low conflict resulted in more similar C-KiddyCAT and KiddyCAT scores. Neither caregiver confidence nor observer-rated stuttering severity influenced the relationship between C-KiddyCAT and KiddyCAT scores. CONCLUSIONS Although many caregivers predicted communication attitude ratings that closely aligned with their child's report, some caregiver-child dyads provided divergent ratings. Clinicians should interpret caregiver predictions of their child's communication attitude within the context of their full evaluation and the caregiver-child relationship. Assessing both self-reported communication attitude and caregiver predictions of their child's communication attitude provides a meaningful starting point to counseling caregivers about cognitive components of stuttering for preschool- and kindergarten-age children who stutter.

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
INTRODUCTION Preschool-age children use mental state verbs (MSVs; e.g., think, know) to reference thoughts and other cognitive states. In play-based language, MSV use requires conversational flexibility, as speakers shift from discussion of actions happening in the here-and-now to more abstract discussion of mental states. Some evidence suggests that children who stutter (CWS) demonstrate subtle differences in shifting on experimental tasks of cognitive flexibility, differences which may extend to conversational flexibility. This study explored MSV use in conversational language between CWS and their mothers. METHODS Thirty-five preschool-age CWS and 35 age- and gender-matched children who do not stutter (CWNS), all performing within the typical range on standardized language testing, conversed with their mothers during play. Samples were transcribed and coded for MSV use. RESULTS No between-group differences were observed in MSV use, either between the CWS and CWNS or between the groups of mothers. Age and language skills were positively associated with MSV use in the CWNS group only. For both groups of dyads, mothers' MSV use corresponded at least to some extent to their children's language skills. Finally, correspondence between CWNS and their mothers was observed for two conversational language measures, representing lexical diversity and morphosyntax; this overall pattern was not observed in the CWS dyad group. CONCLUSIONS Although these findings point to similar use of MSVs among the groups of children and their mothers, for the CWS group, the patterns of use in relation to age and language skills are somewhat different from developmental expectations.

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 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
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 Previous studies have shown that individuals who stutter exhibit abnormal speech perception in addition to disfluent production as compared with their nonstuttering peers. This study investigated whether adult Chinese-speaking stutterers are still able to use knowledge of statistical regularities embedded in their native language to recognize spoken words and, if so, how much acoustic information is needed to trigger this information. METHOD Seventeen stutterers and 20 typical, nonstuttering controls participated in a gating experiment. All participants listened to monosyllabic words that consisted of syllables and lexical tones and were segmented into eight successive gates. These words differed in syllable token frequency and syllable-tone co-occurrence probability in line with a Chinese spoken word corpus. The correct syllable-only, correct tone-only, correct syllable-tone word, and correct syllable-incorrect tone responses were analyzed between the two groups using mixed-effects models. RESULTS Stutterers were less accurate overall than controls, with fewer correct syllables, tones, and their combination as words. However, stutterers showed consistent and reliable perceptual patterns triggered by statistical information of speech, as reflected by more accurate responses to high-frequency syllables, high-probability tones, and tone errors all in manners similar to those of nonstuttering controls. CONCLUSIONS Stutterers' atypical speech perception is not due to a lack of statistical learning. Stutterers were able to perceive spoken words with phonological tones based on statistical regularities embedded in their native speech. This finding echoes previous production studies of stuttering and lends some support for a link between perception and production. Implications of pathological, diagnostic, and therapeutic conditions of stuttering are discussed.

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
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
The purpose of this paper is to present a tutorial on a diagnostic framework developed to assess children who stutter and exhibit co-existing disorders. While we have guidelines for treating these children, there are no specific guidelines for assessing them. We provide a rationale for the development of T-PALS with support from the literature. The T-PALS framework assesses 5 foundational key elements for the child: Temperament (T), Pragmatics (P), Articulation/phonology (A), Language (L), and Stuttering (S). Both qualitative and quantitative measures are used within each dimension. This framework is discussed with reference to using two clinical case examples. T-PALS observation data are presented as well as treatment suggestions for each case. We conclude that T-PALS may be a useful framework for both clinicians and researchers, working with children who present with stuttering and comorbid conditions. Clinicians are encouraged to reach beyond the traditional focus on solely assessing the stuttering behavior, even when that is the main concern for referral, and to consider a broader view of the child. It is hoped that this more integrative approach to assessment may yield a more holistic diagnostic picture of a dual diagnosis child from which treatment goals can be derived.

Abstract
INTRODUCTION The present study investigated potential differences in respiratory sinus arrhythmia between preschool-age children with persisting stuttering, children who recovered from stuttering, and children who do not stutter. METHODS Participants were 10 children with persisting stuttering (persisting group), 20 children who recovered from stuttering (recovered group), and 36 children who do not stutter (non-stuttering group). Participants viewed a neutral video clip to establish a pre-arousal baseline and then viewed two emotionally-arousing video clips (positive and negative, counterbalanced). Age-appropriate speaking tasks followed each of the video clips (post-baseline, post-positive, and post-negative). Respiratory sinus arrhythmia (RSA), an index of parasympathetic nervous system activity, was measured during the video clips and subsequent speaking tasks. RESULTS First, the persisting group, recovered group, and non-stuttering group did not significantly differ in baseline RSA. Second, during the emotionally-arousing video clips, there was a significant group x condition interaction, with the recovered group exhibiting significantly lower RSA in the positive than negative condition, and the non-stuttering group exhibiting significantly higher RSA in the positive than negative condition. Third, in the narrative tasks, there was a significant group x condition interaction, with a greater difference in RSA between the post-baseline speaking task and the post-positive and post-negative speaking tasks for the persisting compared to the non-stuttering group. Lastly, a follow-up analysis indicated that the recovered and nonstuttering groups, compared to the persisting group, exhibited significantly greater RSA during the baseline (neutral) condition compared to the post-neutral narrative task. CONCLUSIONS Findings provide a physiological perspective of emotion within children who stutter and persist and children who stutter and recover. Future investigations with larger sample sizes and diverse methodologies are necessary to provide novel insights on the specific emotion-related processes that are potentially involved with persistence of stuttering in young children.

Abstract
INTRODUCTION Behavioral and questionnaire-based studies suggest that children who stutter (CWS) exhibit poorer response inhibition than children who do not stutter (CWNS). However, the behavioral findings in adults who stutter (AWS) are less unequivocal and mainly based on manual response inhibition. Further study is therefore needed, especially given the lack of studies on verbal response inhibition among these groups. METHODS Thirteen AWS and 14 adults who do not stutter (AWNS) participated in a verbal stop signal task (SST) in which they were asked to read aloud six Chinese characters as fast as possible during the go-signal and ignore-signal trials and refrain from naming them during the stop-signal trials. RESULTS The two groups showed a comparable response reaction time in the go-signal and ignore-signal trial conditions. Furthermore, there were no significant differences in terms of the stop-signal reaction time (SSRT) and accuracy. However, a significant positive correlation was found between SSRT and the frequency of stuttering in conversation but not in reading. CONCLUSION Current findings seem to provide additional support that exogenously triggered response inhibition among AWS does not differ from AWNS. The association between stuttering frequency and SSRT seems to suggest that individuals with more severe stuttering in conversational speech have reduced exogenous response inhibition. However, this finding needs to be further explored in future studies using different measures of stuttering severity.

Abstract
PURPOSE Over the last few years, research findings have suggested limitations in executive function (EF) of children who stutter (CWS) with the evidence being more consistent in studies with preschoolers (3-6 years old) than in studies with school-aged children (6-12 years old). The purpose of the current study was to assess complex response inhibition and cognitive flexibility in school-aged CWS and their non-stuttering peers. METHODS Participants, 19 CWS (mean age = 7.58 years, range 6.08-9.17) and 19 age-and gender-matched children who do not stutter (CWNS; mean age = 7.58 years, range 6.08-9.33), completed a visual task consisting of three task blocks. Analyses were based on response times and error percentages during the different task blocks. RESULTS All participants showed expected performance-costs in task block comparisons targeting complex response inhibition and cognitive flexibility. Significant group differences were found in measures of cognitive flexibility with CWS performing slower compared to CWNS (p = 0.02). Additionally, significant block × group interactions demonstrated that CWS, compared to CWNS, slowed down more (i.e., higher performance-cost) under both complex response inhibition (p = 0.049) and cognitive flexibility task conditions (p = 0.04 for no-set-shifting and p = 0.02 for set-shifting). CONCLUSION These results are in line with some of the previous findings in school-aged CWS and suggest that CWS present lower performance in complex response inhibition and cognitive flexibility task conditions when compared to their non-stuttering peers.

Abstract
PURPOSE Recent research findings suggest possible weaknesses in cognitive flexibility (CF) in children who stutter (CWS) when compared to children who do not stutter (CWNS). Studies so far, have been conducted with either younger (3-6 years old) or older children (6-12 years old) with a variety of measures. The purpose of the present study was to investigate CF with the use of a single behavioral measure across a broader age range (4-10 years old). METHODS Participants were 37 CWS (mean age = 6.90 years) and 37 age-and gender-matched CWNS (mean age = 6.88 years), divided in a younger (below 7 years) and older (above 7 years) age group. All participants undertook a computerized visual set-shifting task consisting of three blocks. CF was evaluated through across-and within-block comparisons of the actual response speed and accuracy values. In addition, mixing-and set-shifting-costs were evaluated based on the mean response speed and accuracy. RESULTS All participants showed expected mixing-and set-shifting-costs. Only the within-block analyses yielded significant between (sub)group differences. Investigation of the block × classification group × age group interactions showed that older CWS had larger set-shifting-costs (slowed down more and made more errors) compared to older CWNS. CONCLUSION While all participants required more time during set-shifting trials, only the older CWS (7-10 years old), and not younger CWS, were slower and made more errors. This finding corroborates previous findings in CWS of a similar age and could possibly point to a role of CF in stuttering persistence.

Abstract
PURPOSE The aim of the study was to assess whether emotional reactivity, indexed by a distinct physiological measure of sympathetic activation, differs between preschool-age children who stutter (CWS) and preschool-age children who do not stutter (CWNS) during a child-friendly Stroop task (i.e., day-night task). Additionally, researchers aimed to assess whether the Stroop task, compared to a control task, was a significant physiological stressor. METHOD Fifteen preschool-age CWS and 22 preschool-age CWNS were asked to perform a day-night Stroop task in order to elicit psychophysiological reactivity, indexed by electrodermal response (EDR) occurrence frequency and EDR amplitude. Physiological measurements were recorded during pretask baselines, performance of the day-night Stroop task, and performance of a speech-language control task. RESULTS Findings based on EDR measures did not support the hypothesis that the child-friendly day-night Stroop task is an effective stressor as compared to a control task based on measures of physiological arousal in preschool-age children. The CWS and CWNS did not significantly differ in their EDR measures relative to the control task or Stroop task (p > .05). However, CWS, compared to CWNS, exhibited significantly greater EDR amplitudes during the control task baseline (p < .05) and the Stroop task baseline (p < .05). CONCLUSION Overall, these findings may suggest that a predisposition to heightened levels of sympathetic activity prior to tasks in preschool-age CWS is important to consider with regard to the nature of developmental stuttering.

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
INTRODUCTION Increased emotional reactivity and decreased regulation have been associated with increased stuttering severity and frequency in preschool children who stutter (CWS) and may be predictors for the development of negative reactions to stuttering in young children. Understanding which children are likely to be impacted to a greater or lesser degree has implications for clinical decision making. Associations between temperament and stuttering impact have been explored with older CWS, but not with preschool CWS. AIM To investigate the relationship between temperament (specifically emotional reactivity and regulation) and both stuttering frequency and stuttering impact in preschool CWS. METHODS Data collected at initial assessment for 119 young CWS (age range= 3;00-6;11 years) at a specialist centre for stuttering in London, UK were analysed. The following measures were completed: The Children's Behaviour Questionnaire-Short Form (Putnam & Rothbart, 2006); Palin Parent Rating Scales (Millard & Davis, 2016); The Communication Attitude Test for Preschool and Kindergarten Children Who Stutter (Vanryckeghem & Brutten, 2007); and a stuttering frequency measure. RESULTS Emotional reactivity and regulation were not significantly associated with stuttering frequency. Higher scores on negative reactivity were significantly associated with an increased impact of stuttering on the child (from parents' perspective), but not significantly associated with child-reported communication attitude. Positive reactivity was not significantly associated with parent-reported impact of stuttering or child-reported communication attitude. Additional investigation revealed negative affect as a significant predictor of parent-reported impact of stuttering before and after adjusting for age. DISCUSSION The results provide evidence to support the role of temperament on the impact that stuttering has in the early years. While the directionality of the relationship between negative reactivity and impact of stuttering is unknown, the importance of targeting emotional reactions in therapy for young CWS is implicated.

Abstract
PURPOSE The main aim of this study was to gain insight into whether temperament and/or stuttering severity were associated with anxiety and depression in children who stutter. Additionally, the study also provided an indication into the prevalence of anxiety and depression in children who stutter in a clinical cohort. 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
PURPOSE Past findings indicate the quality and quantity of emotion regulation often differs between preschool-age children who stutter (CWS) and children who do not stutter (CWNS). The purpose of this study was to identify whether specific emotion-related regulatory strategy types differ between preschool-age CWS and CWNS during a temptation task. METHODS Participants were 13 CWS and 13 CWNS between 3;2 and 5;7 (years;months), matched for gender and age (+/- 6 months). Participants completed a Forbidden Toy paradigm, a resistance to temptation task, in which the children were asked to refrain from touching a toy. Types of emotion-related regulation, including (1) verbal regulation, (2) behavioral regulation, and (3) attentional regulation, were behaviorally coded during the temptation task. RESULTS A higher proportion of the CWNS (92%) failed to resist the temptation to touch the toy than CWS (48%). Additionally, a higher proportion of the CWS (23%), compared to CWNS (0%), presented with signs of distress, resulting in their task ending prematurely. Limited differences were detected in the types of emotion-related regulatory strategies used by CWS, or the frequency of those strategies. CWNS, compared to the CWS, used more approach-related behavioral strategies. CONCLUSIONS Interpretations of these findings must be mitigated by the observation that a higher proportion of CWS than CWNS demonstrated distress during the paradigm, suggesting a need for further research into the interplay between emotional reactivity and emotion regulation for preschool-age CWS.

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.

Developmental Factors That Predict Head Movement During Resting-State Functional Magnetic Resonance Imaging in 3-7-Year-Old Stuttering and Non-stuttering Children. Front Neurosci 2021; 15:753010.

Abstract
Early childhood marks a period of dynamic neurocognitive development. Preschool-age coincides with the onset of many childhood disorders and is a developmental period that is frequently studied to determine markers of neurodevelopmental disorders. Magnetic resonance imaging (MRI) is often used to explore typical brain development and the neural bases of neurodevelopmental disorders. However, acquiring high-quality MRI data in young children is challenging. The enclosed space and loud sounds can trigger unease and cause excessive head movement. A better understanding of potential factors that predict successful MRI acquisition would increase chances of collecting useable data in children with and without neurodevelopmental disorders. We investigated whether age, sex, stuttering status, and childhood temperament as measured using the Child Behavioral Questionnaire, could predict movement extent during resting-state functional MRI (rs-fMRI) in 76 children aged 3–7 years, including 42 children who stutter (CWS). We found that age, sex, and temperament factors could predict motion during rs-fMRI scans. The CWS were not found to differ significantly from controls in temperament or head movement during scanning. Sex and age were significant predictors of movement. However, age was no longer a significant predictor when temperament, specifically effortful control, was considered. Controlling for age, boys with higher effortful control scores moved less during rs-fMRI procedures. Additionally, boys who showed higher negative affectivity showed a trend for greater movement. Considering temperament factors in addition to age and sex may help predict the success of acquiring useable rs-fMRI (and likely general brain MRI) data in young children in MR neuroimaging.

Abstract
Purpose Adults who stutter (AWS) often attempt, with varying degrees of success, to suppress their stuttered speech. The ability to effectively suppress motoric behavior after initiation relies on executive functions such as nonselective inhibition. Although previous studies found that AWS were slower to inhibit manual, button-press response than adults who do not stutter (AWNS), research has yet to confirm a consistent relationship between manual and verbal inhibition. No study has examined verbal inhibition ability in AWS. The purpose of this study, therefore, is to compare verbal response inhibition between AWS and AWNS, and compare verbal response inhibition to both the overt stuttering and the lived experience of stuttering. Method Thirty-four adults (17 AWNS, 17 AWS) completed one manual and three verbal stop-signal tasks. AWS were assessed for stuttering severity (Stuttering Severity Instrument-Fourth Edition: SSI-4) and experience with stuttering (Overall Assessment of the Speaker's Experience With Stuttering [OASES]). Results Results indicate no correlation between manual and verbal inhibition for either group. Generalized linear mixed-model analyses suggested no significant group differences in manual or verbal inhibition. Manual and verbal inhibition did not predict SSI-4 in AWS. However, verbal inhibition was uniquely associated with OASES scores. Conclusion Although underlying manual and verbal inhibition was comparable between AWS and AWNS, verbal inhibition may be linked to the adverse experience of stuttering rather than the overt symptoms of stuttering severity.

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.

PURPOSE We compared school-age children who stutter (CWS) and age and gender matched control participants (CWNS) in a dual-task involving a word-level rhyming task and a tone task involving pitch decisions. METHODS Participants were 30 children (CWS, n = 15) between 7 and 16 years. Auditory word - picture stimuli pairs from the rhyme task were categorized into nonrhyme (e.g., bear-cart), rhyme (e.g., bear-pear), and replica (e.g., bear-bear) categories. The effort associated with managing resources in the dual-task was varied through the manipulation of stimulus onset asynchrony (SOA) between the stimuli of the two tasks. Mixed methods analyses of the response time (RT, ms) and error (%) data were conducted with Group, Category, and SOA as the fixed effects and participants as the random effect. Age and phoneme awareness skills were included in the analyses. RESULTS More rhyming errors and a significant positive correlation between rhyming errors and age was observed in the CWS compared to the CWNS. Compared to the CWNS, a higher percentage of rhyming errors was observed in the rhyme than the nonrhyme and replica categories in the CWS in both the SOA conditions, and this effect was influenced by age and phoneme awareness skills. Analysis of the tone task data indicated that a subgroup of CWNS with higher phoneme awareness skills showed reduced RT difference between the long and the short SOA conditions thereby suggesting higher efficiency with resource allocation for dual tasking. Task-specific differences between the CWS and CWNS are interpreted to suggest limitations in the encoding of the phonological aspects of covert speech in a dual-task.

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 Recent studies have shown that many children who stutter may have elevated characteristics of attention-deficit/hyperactivity disorder (ADHD). Although childhood ADHD commonly persists into adulthood, it is unclear how many adults who stutter experience aspects of ADHD (e.g., inattention or hyperactivity/impulsivity). This study sought to increase understanding of how ADHD characteristics might affect individuals who stutter by evaluating (a) whether elevated ADHD characteristics are common in adults who stutter, (b) whether elevated ADHD characteristics in adults who stutter were significantly associated with greater adverse impact related to stuttering, and (c) whether individual differences in Repetitive Negative Thinking (RNT) and Effortful Control influenced this relationship. Method Two hundred fifty-four adults who stutter completed the Adult ADHD Self-Report Scale, the Perseverative Thinking Questionnaire, the Adult Temperament Questionnaire short form, and the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed via multiple linear regression to determine whether the number of inattention or hyperactivity/impulsivity characteristics was significantly associated with RNT, Effortful Control, or Adverse Impact related to stuttering. Results Almost one quarter of participants (23.2%; 60/254) self-reported experiencing six or more inattention characteristics, while fewer participants (8.3%; 21/254) self-reported experiencing six or more hyperactivity/impulsivity characteristics. Participants with lower Effortful Control and higher levels of both RNT and Adverse Impact were significantly more likely to self-report experiencing more inattention characteristics. Discussion Many adults who stutter may exhibit previously unaccounted for characteristics of ADHD, especially inattention. Results highlight the value of continued research on the intersectionality of stuttering, ADHD, and attention, and the importance of individualizing therapy to the needs of each unique person who stutters.

Abstract
PURPOSE Event-related brain potentials (ERPs) were used to investigate the neural correlates of emotion processing in 5- to 8-year-old children who do and do not stutter. METHODS Participants were presented with an audio contextual cue followed by images of threatening (angry/fearful) and neutral facial expressions from similarly aged peers. Three conditions differed in audio-image pairing: neutral context-neutral expression (neutral condition), negative context-threatening expression (threat condition), and reappraisal context-threatening expression (reappraisal condition). These conditions reflected social stimuli that are ecologically valid to the everyday life of children. RESULTS P100, N170, and late positive potential (LPP) ERP components were elicited over parietal and occipital electrodes. The threat condition elicited an increased LPP mean amplitude compared to the neutral condition across our participants, suggesting increased emotional reactivity to threatening facial expressions. In addition, LPP amplitude decreased during the reappraisal condition- evidence of emotion regulation. No group differences were observed in the mean amplitude of ERP components between children who do and do not stutter. Furthermore, dimensions of childhood temperament and stuttering severity were not strongly correlated with LPP elicitation. CONCLUSION These findings are suggestive that, at this young age, children who stutter exhibit typical brain activation underlying emotional reactivity and regulation to social threat from peer facial expressions.

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 There are several studies showing contradictory results on concurrent emotional and behavioural problems of children and adolescents who stutter (CAWS). This study aimed to identify whether there is a difference between Turkish-speaking CAWS and their typically developing peers (TDP) in emotional and behavioural problems. METHODS The study group consisted of 45 CAWS, aged between 3.40 and 15.92 years, and the control group consisted of 45 TDP, aged between 3.15 and 16.80 years. Participants were divided into three age groups: early childhood (0-6 years), middle childhood (7-11 years) and adolescence (12-18 years). CAWS and TDP were compared separately in each age group with Mann-Whitney U tests. Assessments of emotional and behavioural problems were conducted with the Child Behaviour Checklist (CBCL) for Ages 1.5-5 and the CBCL for Ages 6-18. RESULTS In early childhood, CAWS had significantly higher emotional reactivity, anxiety/depression, somatic complaints, withdrawal, sleep problems, attention problems and aggressive behaviour scores than TDP. In middle childhood and adolescence, CAWS had significantly higher anxiety/depression, withdrawal/depression, social problems, attention problems, rule-breaking behaviour and aggressive behaviour scores compared to TDP. In adolescence, somatic problems and thought problems scores were also significantly higher in AWS than TDP. CONCLUSIONS We concluded that emotional and behavioural problems associated with stuttering are noticeable from early childhood to adolescence. Cooperation with mental health professionals may be needed to improve the quality of speech therapy in CAWS.

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 The purpose of this study was to examine cognitive flexibility for semantic and perceptual information in preschool children who stutter (CWS) and who do not stutter (CWNS). Method Participants were 44 CWS and 44 CWNS between the ages of 3;0 and 5;11 (years;months). Cognitive flexibility was measured using semantic and perceptual categorization tasks. In each task, children were required to match a target object with two different semantic or perceptual associates. Main dependent variables were reaction time and accuracy. Results The accuracy with which CWS and CWNS shifted between one semantic and perceptual representation to another was similar, but the CWS did so significantly more slowly. Both groups of children had more difficulty switching between perceptual representations than semantic ones. Conclusion CWS are less efficient (slower), though not less accurate, than CWNS in their ability to switch between different representations in both the verbal and nonverbal domains.

Abstract
Stuttering is one of the most well-known speech disorders, but the underlying neurological mechanisms are debated. In addition to genetic factors, there are also major non-genetic contributions. It is here proposed that infection with group A beta-hemolytic streptococcus (GAS) was a major underlying cause of stuttering until the mid-1900s when penicillin was introduced in 1943. The main mechanism proposed is an autoimmune reaction from tonsillitis, targeting specific molecules, for example within the basal ganglia. It is here also proposed that GAS infections may have continued to cause stuttering to some extent, to the present date, though more rarely. If so, early diagnosis of such cases would be of importance. Childhood cases with sudden onset of stuttering after throat infection may be particularly important to assess for possible GAS infection. The support for this hypothesis primarily comes from three lines of argument. First, medical record data from the 1930s strongly indicates that there was one type of medical event in particular that preceded the onset of childhood stuttering with unexpected frequency: diseases related to GAS throat infections. In particular, this included tonsillitis and scarlet fever, but also rheumatic fever. Rheumatic fever is a childhood autoimmune sequela of GAS infection, which was a relatively widespread medical problem until the early 1960s. Second, available reports of changes of the childhood prevalence of stuttering indicate striking parallels between stuttering and the incidence of rheumatic fever, with: (1) decline from the early 1900s; (2) marked decline from the introduction of penicillin in the mid 1940s; and (3) reaching a more stable level in the 1960s. The correlations between the data for stuttering and rheumatic fever after the introduction of penicillin are very high, at about 0.95. Third, there are established biological mechanisms linking GAS tonsillitis to immunological effects on the brain. Also, a small number of more recent case reports have provided further support for the hypothesis linking stuttering to GAS infection. Overall, it is proposed that the available data provides strong evidence for the hypothesis that GAS infection was a major cause of stuttering until the mid-1900s, interacting with genetic predisposition.

Abstract
BACKGROUND A considerable amount of research has identified inhibition differences, including slower inhibition of manual responses, in people who stutter. Recent investigations have failed to link slowed motor inhibition with overt stuttering severity. This study investigated the potential relationship between slowed manual response inhibition and the negative impact of stuttering upon individual lives of adults who stutter (AWS). METHODS Thirty-four adults (AWS, n = 17; AWNS, n = 17) matched by nonverbal IQ completed a manual stop-signal task and provided a conversational speech sample. Motor inhibition latency for AWS and AWNS were compared. For AWS, motor inhibition latency was compared to the four subsections of the Overall Assessment of the Speaker's Experience with Stuttering (OASES; Yaruss & Quesal, 2006; General Information, Reactions to Stuttering, Communication in Daily Situations, Quality of Life). RESULTS Similar to previous studies, AWS were significantly slower to inhibit inaccurate manual responses than AWNS. Quality of Life subtest of the OASES was found to significantly predict inhibition latency. CONCLUSION These data replicate findings that indicate that AWS exhibit slower manual inhibition latency, and suggest that these inhibition differences may be associated with an individual's negative experience with stuttering rather than stuttering severity.

Abstract
Background The aim of this study was to investigate the relationship between executive function (EF), stuttering, and comorbidity by examining children who stutter (CWS) and children who do not stutter (CWNS) with and without comorbid conditions. Data from the National Health Interview Survey were used to examine behavioral manifestations of EF, such as inattention and self-regulation, in CWS and CWNS. Methods The sample included 2258 CWS (girls = 638, boys = 1620), and 117,725 CWNS (girls = 57,512; boys = 60,213). EF, and the presence of stuttering and comorbid conditions were based on parent report. Descriptive statistics were used to describe the distribution of stuttering and comorbidity across group and sex. Regression analyses were to determine the effects of stuttering and comorbidity on EF, and the relationship between EF and socioemotional competence. Results Results point to weaker EF in CWS compared to CWNS. Also, having comorbid conditions was also associated with weaker EF. CWS with comorbidity showed the weakest EF compared to CWNS with and without comorbidity, and CWS without comorbidity. Children with stronger EF showed higher socioemotional competence. A majority (60.32%) of CWS had at least one other comorbid condition in addition to stuttering. Boys who stutter were more likely to have comorbid conditions compared to girls who stutter. Conclusion Present findings suggest that comorbidity is a common feature in CWS. Stuttering and comorbid conditions negatively impact EF.

Abstract
Purpose We examined the effects of physiological arousal on speech motor control and speech motor practice effects in preschool-age children who do (CWS) and do not stutter (CWNS). Method Participants included 18 CWS (M age = 4 years 5 months) and 18 age- and gender-matched CWNS. The participants repeated a phrase "buy bobby a puppy" interspersed with viewing pictures from the International Affective Picture System under two experimental conditions speaking after viewing pictures with (a) negative and (b) neutral valence. Participants' lip movements were tracked using Optotrak system. The spatiotemporal index and mean utterance duration were calculated to examine speech motor control and speech motor practice effects. Skin conductance level was measured during the experimental conditions to assess participants' physiological level of arousal. Results Preschool-age CWS demonstrated greater speech movement variability across all conditions and trials than CWNS. Furthermore, the younger participants produced more variable articulatory movements than the older participants. Participants' speech movement variability did not significantly differ between the negative and neutral experimental conditions, and the level of physiological arousal did not have a significant effect on it. There was a nonsignificant trend of decrease in speech movement variability across the repeated trials in both groups. Last, CWS and CWNS did not differ in their mean utterance duration, suggesting that their articulation rate was similar across all conditions and trials. Conclusions Our findings indicate that, compared to preschool-age CWNS, CWS demonstrate less mature speech motor control. However, present findings do not support the hypothesis that CWS benefit less from motor practice relative to CWNS. Given that our conditions elicited similar levels of arousal in the participants, future research is needed to examine whether physiological arousal disrupts speech motor control in preschool-age children potentially contributing to disruptions of speech fluency and the development of stuttering.

Abstract
Purpose This study reports findings from a clinical trial that implemented an early stuttering treatment program integrated with evidence-based parenting support (EBPS) to children who stutter (CWS) with concomitant self-regulation challenges manifested in elevated attention-deficit/hyperactivity disorder (eADHD) symptoms and compared those outcomes to CWS receiving stuttering treatment without EBPS. Method Participants were 76 preschool CWS and their parent(s). Thirty-six of these children presented with eADHD and were quasirandomized into two groups: stuttering treatment only (eADHDstandard) or stuttering treatment integrated with EBPS (eADHDintegrated). The remaining children did not meet criteria for eADHD symptoms and received stuttering treatment only (No-eADHDstandard). Pre, post, and 3-month follow-up measures of stuttering treatment outcomes as well as treatment effects on measures of child behavior difficulties and parenting practices were examined. Results Significant reduction in stuttering was found for all groups. However, the eADHDintegrated group showed a greater reduction in stuttering frequency than the eADHDstandard group, and at follow-up, stuttering frequencies in the eADHDintegrated group matched those of children in the No-eADHDstandard group, while stuttering in the eADHDstandard group remained significantly higher. Children with eADHD symptoms who received the integrated program also required significantly less stuttering intervention time than those children with eADHD symptoms who received stuttering treatment only. Families in the eADHDintegrated group reported large and significant improvements in child behavior and parenting practices. Conclusion This study provides support for an early treatment program for CWS. The integrated stuttering and self-regulation management program for CWS with eADHD symptoms proved successful for fluency and behavioral improvements, which were sustained at follow-up.

Abstract
Purpose Phonological skills have been associated with developmental stuttering. The current study aimed to determine whether the neural processes underlying phonology, specifically for nonword rhyming, differentiated stuttering persistence and recovery. Method Twenty-six children who stutter (CWS) and 18 children who do not stutter, aged 5 years, completed an auditory nonword rhyming task. Event-related brain potentials were elicited by prime, rhyming, and nonrhyming targets. CWS were followed longitudinally to determine eventual persistence (n = 14) or recovery (n = 12). This is a retrospective analysis of data acquired when all CWS presented as stuttering. Results CWS who eventually recovered and children who do not stutter exhibited the expected rhyme effect, with larger event-related brain potential amplitudes elicited by nonrhyme targets compared to rhyme targets. In contrast, CWS who eventually persisted exhibited a reverse rhyme effect, with larger responses to rhyme than nonrhyme targets. Conclusions These findings suggest that CWS who eventually persisted are not receiving the same benefit of phonological priming as CWS who eventually recovered for complex nonword rhyming tasks. These results indicate divergent patterns of phonological processing in young CWS who eventually persisted, especially for difficult tasks with limited semantic context, and suggest that the age of 5 years may be an important developmental period for phonology in CWS.

Abstract
Purpose: The study presents the first review in which the link between attentional ability and developmental stuttering is explored. The review aimed to summarise the published research literature and provide a more conclusive understanding as to the relationship between stuttering and attention.Method: To be included in this review, the studies had to compare the attentional performance of adult people who stutter (PWS) and people who do not stutter (PWNS) over the age of 18 years with a validated psychometric instrument for measuring attentional ability. Articles were searched in four electronic databases where each of the following search terms (attention, vigilance, inhibitory, inhibition, interference, executive and processing) was cross-referenced with each of the following terms (stutter, stammer, speech disfluency and speech dysfluency). A total of 21 studies met the inclusion criteria to be submitted into a meta-analysis.Result: The results of the main meta-analysis, which included all selected studies, demonstrated that PWS had a significantly worse attentional performance as compared to PWNS. Two further meta-analyses on selective attention and dual tasking performance confirmed the latter finding. Importantly, however, the effect was not present in all studies.Conclusion: Our findings should be taken as an indication that stuttering sometimes (but not always) manifests together with poorer attentional ability, such that the identified link does not affect all PWS. These results provide support for the notion that there is a close association between stuttering and attentional ability in a subgroup of PWS, highlighting potential practical implications for stuttering treatment.

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
Purpose Prior research has explored how repetitive negative thinking (RNT) contributes to both the increased persistence and severity of various disorders, such as depression, anxiety, and eating disorders. This study explored the potential role of RNT in the experience of stuttering, with a particular focus on the relationship between RNT, adverse impact, and certain temperament profiles. Method Three hundred thirteen adults who stutter completed a measurement of the frequency/severity of RNT (Perseverative Thinking Questionnaire; Ehring et al., 2011), 207 completed a temperament profile (Adult Temperament Questionnaire; Evans & Rothbart, 2007), and 205 completed a measurement of adverse stuttering impact (Overall Assessment of the Speaker's Experience of Stuttering; Yaruss & Quesal, 2016). Analyses were conducted within and across instruments to ascertain how RNT, temperament markers, and adverse impact interrelate within individuals. Results Results indicated that RNT significantly predicts Overall Assessment of the Speaker's Experience of Stuttering impact scores with great effect and that certain temperament markers (specifically, Effortful Control and Negative Affectivity) moderate this relationship for specific sections of the Overall Assessment of the Speaker's Experience of Stuttering. Conclusion By assessing RNT in people who stutter, clinicians can better understand individual differences in their clients, and this will allow them to make targeted diagnoses and develop more tailored intervention plans.

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
PURPOSE Recent research has identified approximately half of children who stutter present with self-regulation challenges. These manifest in elevated inattentive and/or impulsive behaviours, aligned with attention deficit hyperactivity disorder (ADHD) symptoms. These symptoms have been found to influence the child's responsiveness to their stuttering treatment, and may exacerbate the psychosocial consequences of stuttering for them and their families. Early stuttering intervention identifies parents as key agents of change in the management of their children's stuttering. This study sought feedback from parents regarding their experiences with an integrated stuttering treatment and behavioral self-regulation program for early developmental stuttering, addressing the child's self-regulation challenges. METHOD Eight parents of children who stutter who had co-occurring self-regulation challenges completed the integrated program. This incorporated the Triple P--Positive Parenting Program adapted for the developmental stuttering population, and the Curtin University Stuttering Program (CUSP). Semi-structured qualitative interviews were conducted to capture parents' reflections on, and experiences with, the integrated program. RESULTS Thematic analysis identified several major themes regarding the parents' experiences with the integrated program: emotional impact on parents, child self-regulation, link between stuttering and behaviour, parent self-regulation, impact on family dynamics, and overall positive perceptions of the integrated program. All of the parents indicated they would recommend the program to future parents of children who stutter. CONCLUSION This study provides insights into parents' perceptions regarding an integrated intervention approach for early stuttering and behavior management. It also indicates how adopting a holistic approach to stuttering intervention is positive and has social validity.

Abstract
Purpose We studied speech-related sympathetic nervous system arousal of preschool-age children who do (CWS) and do not stutter (CWNS) and its association with children's proclivity to experience negative emotions and children's self-reported attitudes toward speaking. Method Electrodermal activity measures were collected from 32 preschool-age children while they engaged in a picture description and a nonword repetition task. Children's proclivity to experience negative emotions was assessed with a parent report questionnaire. Children's communication attitude was assessed with a self-report questionnaire. Results CWS did not differ from CWNS in their sympathetic arousal during a picture description task. However, during a more challenging nonword repetition task, preschool-age CWS had a higher sympathetic arousal level than CWNS. Although CWS were rated by their caregivers as more fearful and prone to sadness, children's tendency to experience stronger and more frequent negative emotions was not associated with their sympathetic arousal during speaking. Lastly, although CWS had a more negative communication attitude than CWNS, it was not associated with their level of sympathetic arousal during speaking. Conclusions Our findings suggest that age-appropriate social communication tasks are not inherently more stressful for preschool-age CWS and are not associated with state-related stress or anxiety that is often reported for adults who stutter. However, speaking tasks that place a higher demand on children's cognitive-linguistic system may be more taxing and challenging to preschool CWS than CWNS, leading to a higher level of arousal.

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.

Participants were 100 Portuguese children aged 7 to 12 years (M = 9.13; SD = 1.70), including 50 children who stutter and 50 children who do not stutter. Analyses, which were performed separately for younger and older participants, sought to identify correlations between key variables. Temperament was evaluated through a parent questionnaire, executive functioning was evaluated through children’s responses on a performance test, and anxiety level was assessed through a self-perception scale. On the temperament measure, comparisons between children who stutter and their non-stuttering peers revealed that older children who stutter exhibited significantly higher scores on the Anger/Frustration, Impulsivity, and Sadness subscales, and lower averages on the Attention/Focusing, Perceptual sensitivity, and Soothability/Falling Reactivity subscales. On the executive functioning task, comparisons revealed that the group of younger children who stutter exhibited significantly higher average execution times than their non-stuttering peers. There were no statistically significant differences in anxiety between children who stutter and children who do not stutter, and there were no statistically significant correlations between temperament factors and measures of executive functioning. Children who stutter experienced lower ability to orient attention and greater emotional reactivity compared with their non-stuttering peers. Significant correlations were found between executive functioning and age and among the temperament factors themselves. These results, which support the need for a multidimensional view of stuttering, were interpreted in the context of the Dual Diathesis – Stressor model. Findings indicate that temperament and executive functioning abilities may contribute to the development of stuttering.

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.
