Bidirectional Associations of Childhood Stuttering With Behavior and Temperament

The Association Between Stuttering Burden and Psychosocial Aspects of Life in Adults

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.

Erasmus clinical model of the onset and development of stuttering 2.0

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.

The Fifth Croatia Stuttering Symposium: Part III. Mental health and early stuttering

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.

A study of respiratory sinus arrhythmia and stuttering persistence

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.

Emotional Regulation and Its Influence on the Experience of Stuttering Across the Life Span

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.

Contemporary Theories of Stuttering Development

The article presents a theoretical analysis of contemporary models of persistent stuttering development in children and adults at the current period of development of science. The accumulated amount of scientific knowledge suggests that stuttering has a neurological basis: it is associated with disorders in the structure and function of the brain. On this basis, there have been emerged models of stuttering that link the cause of a speech disorder with an unstable speech motor system. Theories and models of stuttering based on cognitive and language processing are likely to be useful in that they have explanatory power in relation to the mechanisms that play an important role in the production of key symptoms of stuttering. Considering that stuttering is a complex disorder, the logical result of this was the proposal of multifactorial models of impaired speech fluency. The presented overview may be useful to psychiatrists, clinical psychologists, speech therapists, teachers, and practitioners interacting with children and adults with stuttering and other speech fluency disorders.
