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...

BACKGROUND: For children older than 6 years who stutter, there is a gap in clinical research. This is an issue for speech-language pathologists because the tractability of stuttering decreases and the risk of long-term psychological consequences increase with age. PURPOSE: To report a Phase II trial of a telehealth version of the Lidcombe Program with school-age children. METHODS: Participants were 37 children who stuttered, 6-12 years of age, from Australia, New Zealand, Hong Kong, and Singapore...

PURPOSE: To document the trajectory of early childhood stuttering longitudinally for 14. years with a consideration on the features of overt and covert stuttering related to recovery status. METHOD: Thirty-eight participants were observed longitudinally at three different time points: early childhood (Occasion 1), middle childhood (Occasion 2), and late adolescence (Occasion 3). Data collection involved speech samples and reports of stuttering experiences...

PURPOSE: Our study aimed to translate the Stuttering Generalization Self-Measure (SGSM) into Persian and investigate its validity, reliability, and internal responsiveness in the Iranian population. METHOD: This study was conducted on 30 adults who stutter (AWS) and 30 adults who do not stutter (AWNS). The International Quality of Life Assessment protocol (IQOLA) was applied to translate SGSM into Persian. The face and content validity were determined. Also, the discriminant validity was evaluated by comparing the scores of two groups...

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...

PURPOSE: This study aimed to identify what types of major discrimination have been experienced by adults who stutter throughout their lives, and investigate the association between the number of different types of major discrimination events experienced and quality of life. METHODS: Measures of quality of life (Kemp Quality of Life Scale) and major discrimination (adapted Major Experiences of Discrimination Scale) were completed by 303 adults who stutter. Correlational and regression analyses were conducted with these variables...

BACKGROUND: Differences in core auditory processing abilities, such as sound timing, frequency discrimination, auditory perception, and auditory memory, have been suggested in stutterers, despite the fact that the precise origin of stuttering is not entirely understood. It is suggested that these differences may play a role in the development of stuttering. The aim of our study is to assess the temporal central auditory processing performance in individuals with stuttering and compare it to individuals without stuttering to uncover potential differences stuttering and compare it to individuals without stuttering to reveal potential differences...

PURPOSE: Prior research has revealed people who stutter experience role entrapment in which they are discouraged from pursuing certain careers over others. The Vocational Advice Scale (VAS; Gabel et al., 2004) is a reliable survey previously used to investigate this phenomenon. This study used the VAS to determine if communication skills required for careers influences reports of role entrapment. METHOD: An online survey which included the VAS and perceptions of communication skills needed for each career listed on the VAS was distributed...

PURPOSE: Neurophysiological studies report that people who stutter (PWS) exhibit enhanced motor preparation before they stutter. This motor preparation pattern raises the possibility of detecting upcoming stutter moments before they actually occur. This study examined whether these motor preparation differences are detectable by listeners in the corresponding acoustic signal, thereby allowing them to predict upcoming stuttering moments. If so, features in these acoustic patterns could potentially be employed by computational procedures to automate detection of upcoming stutters and to target auditory feedback alterations specifically on these locations...

PURPOSE: This study compared the attitudes toward stuttering among college students in China and the USA using the POSHA-S survey, which assesses knowledge about stuttering and attitudes toward it. We investigated how cultural and social differences between the two groups influenced these attitudes. METHODS: We collected 199 responses to the POSHA-S survey from various universities in China and the USA. We conducted a statistical analysis of 15 summary scores generated from the POSHA-S to determine if there were significant differences in attitudes toward stuttering between the two groups...

PURPOSE: Previous studies have shown increased prevalence of sleep problems among people who stutter. However, there is a lack of knowledge about what these sleep problems may specifically be. METHOD: Fifty children who stutter (CWS) from 6;0 to 12;9 years of age and 50 age- and gender-matched controls participated in this study. Parents did not report coexisting conditions, excepting stuttering and/or sleep problems. Sleep problems were investigated using a standardized questionnaire answered by parents...

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)...

This is the fourth in a series of papers that provides an historical record in this journal of contributions made by the most influential figures in the field of stuttering. Ann Packman is an Australian researcher who will retire shortly. This paper reflects on her long and productive career, and her contributions to the field. With a background in literature, linguistics, philosophy, psychology, and the brain and language, she became well equipped to contribute to understanding stuttering causality. That work, and an accompanying collection of basic and applied clinical research, was constantly grounded with the thoughts and feelings of those who stutter in the community...

PURPOSE: The Fifth Croatia Stuttering Symposium in 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 first of three Symposium modules. METHODS: The module topic was that three treatments for early childhood stuttering are supported by randomized controlled trial evidence. A clinical situation was considered where a parent of a 3-year-old child asked what results to expect of stuttering treatment...

PURPOSE: The aim of this study is to compare the speech fluency performance of non-fluent participants namely people with stuttering (PWS), people with cluttering (PWC) and people with cluttering and stuttering (PWCS) with a fluent control group using the Turkish version of Predictive Cluttering Inventory-revised (TR-PCI-r). METHODS: The study recruited non-fluent individuals (n = 60) and fluent controls (n = 60) between the ages of 6 and 55...

PURPOSE: Instagram has become a popular platform for sharing and seeking health-related information, including stuttering. However, concerns have been raised about the accuracy, confidentiality, and potential negative impact of such information. This study aims to examine how stuttering is defined and understood on Instagram, and how users engage with related content. METHODS: We analyzed highly engaged Instagram posts with the hashtag "#Stuttering" published within a year and their corresponding comments using thematic analysis...

PURPOSE: This study aimed to adapt the Self-Stigma of Stuttering Scale (4S) into Turkish and evaluate its factor structure, reliability, and validity in Turkish culture. METHODS: The original 4S scale was translated into Turkish (4S-TR) using a forward-backward translation technique and was administered to 350 adults who stutter (AWS). To discover latent variables evaluated on the scale, two-factor analyses were performed. Internal consistency and temporal stability were calculated to ensure reliability...

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 second of three Symposium modules. METHODS: The module topic was that some children with early stuttering will recover naturally. A clinical situation was considered where a parent of a 3-year-old child asked if a clinician can predict whether their child will recover from stuttering without treatment...
