Abstract
PURPOSE The purpose of this study was to assess the long-term stability of objective and subjective psychosocial improvements and fluency more than 10 years after participation in an intensive stuttering therapy camp. METHOD Ten former participants in intensive stuttering therapy (IST; mean age at time of intervention 14; 2 years) participated in this study. Outcomes of the IST at that time were assessed with the Stuttering Severity Instrument (SSI-3; Riley, 1994) and a questionnaire to measure the psychosocial impact of stuttering. A semi-structured video call and a general questionnaire for the long-term evaluation were used to gauge the participants' perceptions of the IST. These follow-up data were compared to the therapy outcomes reported by Cook (2011, 2013). RESULT Therapy effects on the severity of stuttering and psychosocial impact were stable over the follow-up period of more than 10 years. Moreover, scores for psychosocial impact and severity of stuttering further decreased from the end of the IST to the long-term evaluation. The intensive time and the periodically offered follow-up treatments were described as particularly positive by the participants. CONCLUSION Intensive stuttering therapy in childhood or adolescence can have a long-term positive effect on both internal and external stuttering symptoms.

Abstract
PURPOSE The purpose of this study was to assess self-perceived communication competence of adults who stutter following participation in a non-ableist treatment for which one of the core components focuses on communication - with no direct or indirect goals designed to reduce or modify stuttered speech. METHOD Thirty-three adults who stutter completed the Self-Perceived Communication Competence scale (McCroskey & McCroskey, 1988) pre- and posttreatment. RESULTS Findings indicate significant gains in self-perceived communication competence posttreatment. Pre- to posttreatment changes in stuttering did not predict posttreatment gains in self-perceived communication competence. CONCLUSION The present study demonstrates that improvement in communication can be achieved independent of improvement in fluency, lending further support to the notion that stuttering and communication competence are distinct constructs.

Abstract
Introduction Growing anecdotal evidence suggests the feasibility of robotic intervention for people who suffer from disorders related to state anxiety. Few studies have been conducted on utilizing robots for persons who stutter (PWS). The present study examines the feasibility of using a robot for speech therapy for PWS. Methods We prepared four settings (i.e., interviews with unfamiliar persons, interviews with unfamiliar communication robots, reading sentences aloud with a tandem robot that can utter the same words as a user by repeating the user's voice after a short delay, and reading sentences aloud while being alone). We assessed the potential of the robots as both interlocutors and practice partners in training with delayed auditory feedback (DAF) for PWS. Moreover, we assessed the relationship between the trait of stuttering and the participants' affinity to the robots. Results Eleven PWS participated in the study. Eight (72.7%) participants had fewer stuttering-related psychological symptoms when they communicated with robots than when they communicated with humans. Spearman's rank correlation analysis revealed that there was a significant negative correlation between the Modified Erickson Communication Attitude scale (S-24) and the difference between the scores for stuttering-related psychological symptoms pertaining to the communication robot and humans (p < 0.01). Six participants (54.5%) had fewer stuttering-related psychological symptoms when they read aloud with the tandem robot than when they read aloud alone. There were significant positive correlations between S-24 and the differences between the scores for stuttering-related psychological symptoms when reading aloud with the tandem robot and those when reading aloud alone (p < 0.01). Discussion The communication robot and tandem utterance robot can sometimes be burdensome, although both robots were always easier to talk to for PWS in this preliminary study. The participants with positive speech-related attitudes were more inclined to decrease stuttering-related psychological symptoms when communicating with CommU than when communicating with humans. The participants whose speech-related attitudes were negative were more inclined to show a decrease in stuttering-related psychological symptoms when reading aloud with the tandem robot. Further studies are needed to provide more detailed information.

Abstract
PURPOSE Post-event processing, defined by self-critical rumination following a stressful communication event, is significantly associated with reduced quality of life. However, despite its relevance to the stuttering experience, to date, only a few studies have investigated post-event processing among adults who stutter, and no study has identified clinical and psychosocial predictors of post-event processing. The purpose of this study was to determine the contributions of clinical markers of stuttering and psychosocial variables to post-event processing. METHOD Adults who stutter (N = 96) participated in two virtual sessions. After completing the Trier Social Stress Test, a standardized social stress task in Session 1, participants completed measures of post-event processing, clinical markers of stuttering (i.e., the experience of stuttering, self- and observer-rated stuttering severity), and psychosocial characteristics (i.e., self-perceived performance, self-esteem, social anxiety, trait, and state self-compassion) in Session 2. RESULTS Hierarchical linear regression models indicated that a more negative experience of stuttering, higher self-rated stuttering severity, and greater social anxiety predicted more post-event processing. Greater self-perceived performance and state self-compassion predicted less rumination. Observer-rated severity, self-esteem, and trait self-compassion were not significantly associated with post-event processing behavior. CONCLUSION Findings reveal clinical and psychosocial variables to consider in the assessment and mitigation of post-event processing behavior in adults who stutter, and to bolster resiliency to social stress.

Abstract
BACKGROUND Access to services remains the biggest barrier to helping the most vulnerable in the South African Stuttering Community. This novel stuttering therapy, harnessing an unconscious link between eye and tongue movement, may provide a new therapeutic approach, easily communicated and deliverable online. OBJECTIVES This study provides both objective and subjective assessments of the feasibility of this intervention. Assessment tools holistically address all components of stuttering in line with comprehensive treatment approaches: core behaviours, secondary behaviours, anticipation and reactions. METHOD On receipt of ethical approval, this single-subject case design recruited one adult (21-year-old) male with a developmental stutter (DS). The participant gave informed consent and completed four scheduled assessments: baseline, after 5-week training, 3 months post-intervention and 24 months post-completion. The study used objective assessment tools: Stuttering Severity Instrument-4 (SSI-4); Subjective-assessment tools: SSI-4 clinical use self-report tool (CUSR); Overall Assessment of Speaker's Experience of Stuttering (OASES-A); Premonitory Awareness in Stuttering (PAiS) and Self-Report Stuttering Severity* (SRSS) (*final assessment). RESULTS The participant's scores improved across all assessment measures, which may reflect a holistic improvement. The participant reported that the tool was very useful. There were no negative consequences. CONCLUSION This case report indicates that this innovative treatment may be feasible. No adverse effects were experienced, and the treatment only benefited the participant. The results justify the design of a pilot randomised feasibility clinical trial.Contribution: The results indicate that this is a needed breakthrough in stuttering therapy as the instructions can be easily translated into any language. It can also be delivered remotely reducing accessibility barriers.

Abstract
This study reports a user evaluation of a DVD-based social simulator, developed for people who stutter to potentially gain confidence in using a learned fluency technique. The aim was to examine and evaluate the pilot of the DVD-based social simulator, Scenari-Aid, to inform the development of an online version of the program. Thirty-seven adults who were stuttering were recruited to the study from non-professional groups in Australia. The DVD comprised scenarios with actors in real-life settings that were designed to elicit verbal responses. Participants worked through the scenarios at their own rate and then completed an online survey. The survey comprised 29 statements requiring responses on a 5-point Likert scale and provided information about users' perceptions of participating in the social simulations. There was high positive agreement among the participants on all statements, the most important being that they perceived the scenarios represented in everyday speaking situations and that they felt immersed in them. Participants also agreed that both their fluency and confidence increased in everyday speaking situations as a result of working through the DVD scenarios. The developers were satisfied that, despite the subjective nature of the findings, the study provided sufficient support for constructing the online version, which is now available to the public free of charge. Further research is needed to provide empirical evidence of the contribution it can make to the efficacy of speech programs for adults who stutter.

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

Abstract
PURPOSE This study was designed to answer three questions. (a) Does percentage of syllables stuttered (%SS) differ between standard and challenge phone calls. (b) Does anxiety differ between standard and challenge phone calls. (c) Is there a relationship between %SS and anxiety during standard and challenge phone calls? METHOD Participants were 230 adults diagnosed with stuttering, who were participants from five clinical trials. Each participant received two 10-min phone calls at pretreatment and a further two phone calls 6 months or 20 weeks postrandomization. One phone call was standard, and the other presented challenge: occasionally disagreeing with, interrupting, and talking over participants, or asking for clarification of their views. RESULTS Statistically significant, but clinically minor, increases of %SS and anxiety occurred during the challenge phone calls. There was a statistically significant association between %SS and anxiety. CONCLUSIONS Variable phone call procedures to assess stuttering severity in clinical trials are not likely to spuriously inflate or deflate treatment outcomes to a clinically important extent. Regardless, the present results suggest that there is statistical merit in controlling the nature of phone calls during clinical trials with the simple and replicable method developed in this report. Additionally, there is procedural merit in the challenge phone call procedure; it is a more valid representation of the challenges of everyday speech than the standard procedure. However, a disadvantage of the challenge phone call procedure is the practical issues associated with its use. The clinical and theoretical applications of the results are discussed.

Abstract
AIM We tested whether completion of the Comprehensive Stuttering Program (CSP) is associated with a reduction in speech kinematic variability relative to pre-treatment when adults who stutter (AWS) use a casual speaking manner or fluency skills. RATIONAL Kinematic variability is higher in AWS suggesting a sensorimotor vulnerability; however, it is not clear whether high variability is a trait related to the underlying disorder or reflects the mutable state of stuttering. Speech restructuring intervention such as the CSP could support more consistent articulatory control and stable movement patterns. METHODOLOGY Thirteen AWS were tested before and after completing the CSP while 11 adults who do not stutter (AWNS) completed a single session. Participants were instructed to use a casual manner of speaking in the first post-treatment session. In the second post-treatment condition, the AWS employed their fluency skills at a control speaking rate. An optical tracking system captured lower lip movements while participants spoke two English phrases and a complex nonword. Across-utterance kinematic variability was measured using the spatiotemporal index (STI) and within-utterance variability was measured with recurrence quantification analysis (RQA). RESULTS There was a positive treatment outcome based on significant reductions in percentage syllables stuttered (%SS) during speaking and reading, decreases in stuttering severity and improved perceptions of stuttering and communication confidence. The STI of the AWS decreased significantly after treatment for both speaking styles. The RQA variables indicated that AWS used a less stereotyped and more flexible manner of speaking in the casual condition after treatment, but speech movement regularity increased when using fluency skills. CONCLUSIONS The AWS showed a significant decrease in labial kinematic variability alongside a successful treatment outcome involving speech restructuring and cognitive behavioral techniques. These changes in across-utterance and within-utterance kinematic indices demonstrate that effective stuttering treatment can promote speech motor stability along with fluent speech.

Abstract
BACKGROUND Evidence-based practice involves the synthesis of multiple forms of evidence to inform clinical decision-making and treatment evaluation. Practice- and patient-based evidence are two forms of evidence that are under-represented in the stuttering literature. The collection of such knowledge is essential to support the design and delivery of effective stuttering interventions for adults. AIMS To build stakeholder consensus on the core components of intervention for adults who stutter, and to establish a guiding framework for the design and development of evidence-based interventions for adults who stutter. METHODS & PROCEDURES Adults who stutter and speech and language therapists (SLTs) with experience in providing stuttering intervention participated in the three-round e-Delphi Survey focused on: (1) identifying key stuttering intervention components, including principles, practices, and structural and contextual elements; and (2) obtaining group consensus on stuttering intervention components. Statements were categorized using the International Classification of Functioning, Disability and Health (ICF) model adapted to the study of stuttering. OUTCOMES & RESULTS A total of 48 individuals agreed to participate: 48/48 (100%) completed the Round 1 questionnaire, 40/48 (83%) responded to Round 2 and 36/40 (90%) participated in Round 3. Following content analysis of Round 1, 101 statements were developed, and consensus was achieved on 89 statements perceived as representing the core components of stuttering intervention for adults. Categorization of these statements reflected the key stuttering intervention components relating to personal reactions to stuttering, limitations in life participation and environmental factors. CONCLUSIONS & IMPLICATIONS Consensus on the core components of stuttering intervention was reached through engagement with key stakeholders. The evidence-based framework presented highlights the range of key intervention components a clinician should consider when designing interventions for adults who stutter. WHAT THIS PAPER ADDS What is already known on the subject Evidence-based practice endorses the synthesis of multiple knowledge forms including research, practice and patient evidence to support clinical decision-making and treatment evaluation. The stuttering literature is characterized by an over-representation of efficacy evidence, with significantly less practice and patient evidence to guide clinical practice. What this paper adds to existing knowledge This study adds valuable practice- and patient-based evidence for effective stuttering intervention components for adults who stutter. These relate to personal reactions to stuttering, limitations in life participation and environmental factors. What are the potential or actual clinical implications of this work? This research presents a stakeholder-informed framework for stuttering intervention to guide SLTs working with adults who stutter in designing evidence-based interventions. The framework supports the adoption of a person-centred approach to intervention to ensure each client's unique needs, preferences, values and desired outcomes are explored and integrated into therapy.

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

Abstract
PURPOSE Many school-age children and adolescents who stutter experience the fear of public speaking. Treatment implications include the need to address this problem. However, it is not always possible to train repeatedly in front of a real audience. The present study aimed to assess the relevance of using a virtual classroom in clinical practice with school-age children and adolescents who stutter. METHODS Ten children and adolescents who stutter (aged 9-17 years old) had to speak in three different situations: in front of a real audience, in front of a virtual class and in an empty virtual apartment using a head-mounted display. We aimed to assess whether the self-rated levels of anxiety while speaking in front of a virtual audience reflect the levels of anxiety reported while speaking in front of a live audience, and if the stuttering level while speaking to a virtual class reflects the stuttering level while speaking in real conditions. RESULTS Results show that the real audience creates higher anticipatory anxiety than the virtual class. However, both the self-reported anxiety levels and the stuttering severity ratings when talking in front of a virtual class did not differ from those observed when talking to a real audience, and were significantly higher than when talking in an empty virtual apartment. CONCLUSION Our results support the feasibility and relevance of using a virtual classroom to expose school-age children and adolescents who stutter to a feared situation during cognitive behavioral therapy targeting the fear of public speaking.

Abstract
Purpose Children who stutter (CWS) face communication difficulties in school activities and at home. Although the importance of receiving support from their surroundings has been documented, few studies have investigated potential requests of CWS from their surroundings. This study aimed to elucidate such requests. Method A total of 43 school-age children and 25 adolescents who stutter completed a free-description questionnaire, including questions such as "what you want your classmates/your classroom teacher/your family to do about your stuttering?" Their descriptions were summarized and categorized based on similarity. Results The results indicate that 90.6% of the participants had more than one request for their classmates, classroom teacher, or family. A total of 197 items were extracted and categorized into seven themes. In particular, the responses included "listen attentively," "treat us naturally," and "make arrangements." While participants tended to hope for classmates or family to "listen attentively" and "treat us naturally," the request to "make arrangements" was higher for their teacher. Their potential requests varied by age: While school-age CWS wanted people around them to "listen carefully," the hope of adolescents who stutter was "treat us naturally." Conclusions The various potential requests of CWS were categorized, and the responses shed light on the importance of increasing knowledge of stuttering. The difference between the requests could reflect psychosocial differences between school-age children and adolescents who stutter. In addition, social interaction among peers is more developed in adolescents, and they could harbor fear of being excluded within their community.

Abstract
Purpose The purpose of this review article is to provide an overview of the current evidence base for the behavioral management of stuttering and associated social anxiety. Method We overview recent research about stuttering and social anxiety in the context of contemporary cognitive models of social anxiety disorder. That emerging evidence for self-focused attention and safety behavior use with those who stutter is considered in relation to current treatment approaches for stuttering: speech restructuring and social anxiety management. Results The emerging information about social anxiety and stuttering suggests a conflict between the two clinical approaches. For those clients who wish to control their stuttering and where speech restructuring is deemed the most suitable approach, it is possible that speech restructuring may (a) induce or increase self-focused attention, (b) promote the use of safety behaviors, and (c) become a safety behavior itself. This conflict needs to be explored further within clinical and research contexts. Conclusions The issues raised in this review article are complex. It appears that evidence-based speech treatment procedures are in conflict with current best-practice treatment procedures that deal with social anxiety. In this review article, we propose directions for future research to inform the development of improved treatments for those who stutter and recommendations for interim clinical management of stuttering.

Abstract
For children who stutter (CWS), there is good evidence of the benefits of treatment for pre-school age, but an evidence gap for elementary school age. Here we report on the effectiveness of a fluency shaping treatment for 6- to 9-year-old children. The main treatment component is the reinforcement of soft voice onsets. An intensive in-patient group treatment phase lasts 6 days, followed by a 6-month maintenance phase with 3 in-patient weekend group refresher courses. Child and a parent participate together in various treatment activities. In this controlled intervention study (waitlist control, intention-to-treat design) assessments were performed before treatment (T1), 4 weeks after the intensive phase (T2), at the end of the maintenance phase (T3), and 1 year later (T4). Participants were 119 children (108 boys, 11 girls, age 5.5‑10.4 years). Control conditions included a subgroup with delayed treatment (N=25) as well as the assessment of complexity of utterances, inter-rater reliability, and speech naturalness. From before treatment to 1-year follow-up, percent stuttered syllables and OASES-S (Overall Assessment of the Speaker's Experience with Stuttering - School-age) scores decreased with large effect size. Speech naturalness improved during this period but did not reach the level of non-stuttering children. Complexity of utterances increased during the intensive phase, but only temporarily. Twenty children (16.8 %, including dropouts) showed no demonstrable treatment benefit. Fluency shaping treatment can be effectively applied to young school children. It is assumed that parental support, group therapy, intensive treatment, and regular exercises at home are essential.

Abstract
PURPOSE This study reports outcomes from a stuttering therapy approach that combines value and awareness-based elements from Acceptance and Commitment Therapy (ACT) with those of stuttering and speech modification interventions. The approach, entitled Multidimensional Individualized Stuttering Therapy (MIST), includes a combined clinician and client selection of factors across five areas: 1) general breathing patterns and body tension, 2) breathing patterns during speech production, 3) vocal features in speech production, 4) value and mindfulness-based strategies, and 5) general communication and/or presentation skills. The aims of this study were to evaluate whether the MIST a) reduces the impact of stuttering and stuttering severity, and b) has a positive impact on speaking ability, confidence in communication, avoidance-behavior, and quality of life. METHOD Eighteen adults, age 21-61 years took part in an A-B-A multiple case study design. Participants underwent a pre-clinic assessment phase, followed by 10 h of therapy over four sessions administered by an experienced speech-language therapist. Outcome measures examined both psychosocial and behavioral aspects of therapy three-, six- and twelve-months post-therapy. RESULTS Most participants chose elements from at least four of the five areas of focus. There was a significant reduction in the impact of stuttering at both 6- and 12-months post-therapy, with moderate (d = .71) to very large (d = 1.06) effect sizes. A strong association was found between overall satisfaction with MIST and improved speaking abilities. Moderate to strong associations were also found between experienced speaking abilities, confidence in communication, reduction in avoidance behaviors and improved quality of life. DISCUSSION Findings indicate that MIST can be effective in managing adult stuttering. The findings highlight the importance of shared decision making and personal considerations using flexible therapy approaches that integrate stuttering and speech modification interventions with value and awareness-based skills. The nature of a multidimensional individualized approach, as shown in this study, highlights the importance of adjusting the relative weighting of different subcomponents according to each individual's needs and goals. CONCLUSION MIST was shown to be efficacious in clinical settings and effective in real life settings. Findings were promising, despite a relatively small sample, and replication by other SLPs and with larger samples is warranted.

Abstract
PURPOSE Recent literature stresses the importance of resilience, as a trait, for successful coping with life's difficulties or stressors. However, only a limited number of studies were conducted on resilience among people-who-stutter (PWS). These studies did not examine the association between resilience and the specific characteristics of stuttering. This study was, therefore, aimed to directly examine the association between resilience and measures of both the covert and overt characteristics of stuttering. METHOD Thirty adults who stutter completed the Connor-Davidson Resilience Scale (CD-RISC) and the Overall Assessment of Speaker's Experience of Stuttering - Adults (OASES-A). In addition, stuttering severity of all participants was quantified using the Stuttering Severity Instrument-4 (SSI-4). The associations between all measures were examined statistically. RESULTS A strong and significant association was found between the participants' scores on the CD-RISC and the OASES-A (r= -.79, p < .001). In contrast, no significant correlation was found between the participants' scores in the CD-RISC and the SSI-4 (r = .02, p > .05). Within our cohort, no significant association was observed between the participants' gender and age and their resilience levels (p > 0.05). CONCLUSION This study demonstrates the role of resilience in shaping the individual's experience with stuttering. Results also show that the individuals' resilience levels do not necessarily predict stuttering severity per se, or its overt manifestations but can predict the individuals' subjective perception of his/her stuttering. This highlights the importance of addressing and promoting resilience among PWS in stuttering therapy.

Abstract
PURPOSE Stuttering affects people in individual ways, and there are multiple factors which may influence a person's goals when seeking therapy. Even though there is a common consensus that speech-language pathologists should discuss the individual's goals and expectations for stuttering therapy and outcomes, few studies have systematically investigated this issue. The aims of the present study were to investigate individual motivations and goal-setting related factors in stuttering therapy. The associations between self-reported impact of stuttering and the participants' perceptions of stuttering interference in communication, speaking abilities, and relationships with other people were also investigated. METHOD This study is part of a wider-ranging treatment study of individualized stuttering management tailored to the participants' personal goals and preferences. A mixed method, multiple single-case design was used to address the research questions. Twenty-one adults, age 21-61 years, took part in a pretherapy interview, which also included two quantitative measures: the Client Preferences for Stuttering Therapy-Extended version (CPST-E) and the Overall Assessment of Speakers' Experience of Stuttering-Adult version (OASES-A). Findings from the study sample was compared with a Norwegian reference group, in order to check for the representativeness of the study sample. RESULTS Quantitative data showed that most participants wanted to focus on both physical and psychological aspects of therapy, and that 95% considered 'to gain a sense of control over the stuttering' as important. Participants' perspectives on their speaking ability and stuttering interference in communication were identified as central factors, particularly in social and professional settings. These outcomes aligned well with the finding of avoidance behaviors, such as avoiding words and speaking situations. Qualitative data identified four main areas that the participants wanted to improve: speech fluency, emotional functioning, activity and participation, and understanding of their stuttering. CONCLUSION The study confirms that multiple and individual factors may influence the person's goals for therapy. Goals were mainly anchored in participants' wish of better coping in real world settings. A high degree of avoidance behavior was reported, suggesting that anxiety, and in particular linguistic-related anxiety needs to be taken into account when addressing social anxiety in fluency disorders.

Abstract
PURPOSE Speech rate convergence has been reported previously as a phenomenon in which one's speech rate is influenced by his/her partner's speech rate. This phenomenon has been demonstrated in artificial settings, and to some extent, in mother-child interactions. The purpose of this study was to explore speech rate adjustment in a quasi-natural adult-adult conversation. METHODS An A-B-A-B paradigm was used, in which ten adults conversed on a given topic with two experimenters. Speech rates of both communication partners were measured. RESULTS Participants significantly reduced their speech rate, in response to the experimenters' reduction in speech rate. However, the participants' reduction in speech rate was significantly smaller than the experimenters' reduction in speech rate. In addition, during the controlled slow speech rate, the participants' speech rate correlated negatively with that of the experimenters'. CONCLUSION Results suggest that speech rate convergence is a non-linear phenomenon, and may be affected by various linguistic as well as communicational factors. From a clinical perspective, the results support the use of the modeling strategy in speech therapy, as a means to facilitate a reduction in clients' speech rate.

Abstract
PURPOSE To determine the efficacy of treatment based on Kristin Linklater's technique for vocal preparation for performance for use with people who stutter. METHOD A protocol for a treatment for stuttering involving breathing exercises, relaxation techniques, and focus on awareness was designed by the first author from Linklater's published exercises in her book Freeing the Natural Voice (2006). Four adults who stutter participated in a 12-week, single-case reversal design study. Treatment efficacy was determined by baseline and post-treatment measures on the OASES, self-report naturalness, tension and severity scale, and percentage of stuttering-like disfluency (SLD). Qualitative measures included a daily tension and practice log, a program completion questionnaire, and accounts from the clinicians administering the treatment protocol. RESULTS Three of four participants scored lower on the OASES post-treatment, suggesting that the impact of stuttering on their daily lives had decreased. All four experienced a reduction in the number of SLD counted throughout treatment sessions compared to baseline data. CONCLUSION A treatment for stuttering based on Linklater's work including regulation of breathing, relaxation, and awareness of breath may be effective in improving fluency and decreasing the impact of stuttering and warrants further study.

Abstract
BACKGROUND Approximately 1% of children and adolescents, 0.2% of women, and 0.8% of men suffer from stuttering, and lesser numbers from cluttering. Persistent speech fluency disorders often cause lifelong problems in communication and social participation. METHODS In an interdisciplinary, evidence and consensus based clinical practice guideline, the current understanding of the nature, identification, diagnosis, and treatment of stuttering and cluttering was summarized. A systematic review of the literature was carried out to assess the efficacy and effectiveness of treatments for stuttering. Evidence is lacking on the etiology, pathogenesis, evaluation, and treatment of cluttering. RESULTS In view of the fact that common (developmental, idiopathic) stuttering is associated with structural and functional changes of the brain, the guideline recommends that it should be called "originary neurogenic non-syndromic stuttering." Heritability estimates for this disorder range from 70% to over 80%. For preschool children, the Lidcombe therapy has the best evidence of efficacy (Cohen's d = 0.72-1.00). There is also strong evidence for an indirect treatment approach. For children aged 6 to 12, there is no solid evidence for the efficacy of any treatment. For adolescents and adults, there is good evidence with high effect sizes (Cohen's d = 0.75-1.63) for speech restructuring methods such as fluency shaping; weak evidence with intermediate effect sizes for stuttering modification (Cohen's d = 0.56-0.65); and weak evidence for combined speech restructuring and stuttering modification. The evidence does not support the efficacy of pharmacotherapy, rhythmic speaking, or breathing regulation as the sole or main form of treatment, or that of hypnosis or eclectic, unspecified stuttering therapies. CONCLUSION Stuttering is often treated in Germany with therapies for which there is inadequate evidence, and the initiation of treatment is often unnecessarily delayed. The guideline presents treatment methods whose efficacy is supported by the current evidence.

Abstract
PURPOSE Stuttering can trigger anxiety and other psychological and emotional reactions, and limit participation in society. It is possible that psychological counseling could enhance stuttering treatment outcomes; however, little is known about how clients view such counseling. The purpose of this study was to gain an understanding of clients' experiences with, and perceptions of, a psychological counseling service that was offered as an optional adjunct to speech therapy for stuttering. METHOD Nine individuals who stutter (13-38 years old) participated in semi-structured interviews. Six participants had taken part in psychological counseling; three participants did not do so. Interview data were analyzed using grounded theory as a guiding framework. RESULTS Four thematic clusters emerged from participants' accounts: insights into personal decision-making, why others may not participate in counseling, psychological counseling as a worthwhile part of therapy, and counseling as a necessary component in a stuttering treatment program. CONCLUSION In addition to experiencing barriers and facilitators to help-seeking that are reported in related fields, participants accounts also revealed novel facilitators (i.e., a 'why not' mentality and the importance of having a pre-existing relationship with the clinician who offered the service) and barriers (i.e., viewing the service as a 'limited resource,' and, the overwhelming nature of intensive stuttering treatment programs). Findings suggest that clients value the option to access psychological counseling with trained mental health professionals to support the stuttering treatment provided by speech-language pathologists. Participants made recommendations for the integration of psychological counseling into stuttering treatment programs.

Abstract
This is the third article in a series examining communication restriction in adults with stuttering (AWS). The aim was to explore interpersonal communication behaviour in AWS at long-term treatment follow-up, using systemic functional linguistics (SFL) as an analytical framework. The performance of 10 AWS within 10-minute conversation samples was compared across pretreatment (T1), post-treatment (T2), and 12-month follow-up (T3), in terms of language productivity and complexity, modality, and appraisal. At T1 and T3, comparisons were also made to a control group (AWNS). Post-treatment increases in (1) language complexity, (2) frequency of modal operators, and (3) expression of appraisal were maintained in the AWS group at T3. No significant differences in these areas were found between AWS and AWNS at T3. The findings suggest that intensive comprehensive stuttering treatment can affect lasting functional change in interpersonal language use for AWS.

Abstract
BACKGROUND Despite many years of research, there is no certainty regarding the cause of stuttering. Although numerous interventions have been developed, a broad-based systematic review across all forms of intervention for adults and children was needed including views and perceptions of people who stutter. OBJECTIVE The aims of the study were to report the clinical effectiveness of interventions for people who stutter (or clutter), to examine evidence regarding the views of people who stutter and the views of professionals regarding interventions. DATA SOURCES A systematic review of quantitative and qualitative literature was carried out between August 2013 and April 2014. The following electronic databases were searched: (1) MEDLINE, (2) EMBASE, (3) The Cochrane Library (including The Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, Health Technology Assessment Database and NHS Economic Evaluations Database), (4) PsycINFO, (5) Science Citation Index, (6) Social Science Citation Index, (7) Cumulative Index to Nursing and Allied Health Literature, (8) ASSIA, (9) Linguistics and Language Behavior Abstracts, (10) Sociological Abstracts and (11) the EPPI Centre. Reference lists of included papers and other reviews were screened and also key journals in the subject area were hand-searched. REVIEW METHODS The searches aimed to identify (1) evidence of clinical effectiveness in populations of pre-school children, school-aged children, adolescents and adults, and (2) data relating to perceptions of barriers and facilitators to intervention clinical effectiveness among staff and people who stutter. A metasynthesis of the two linked elements via development of a conceptual model was also carried out to provide further interpretation of the review findings. RESULTS A systematic search of the literature identified a large number of potentially relevant studies. Of these, 111 studies examining the clinical effectiveness of interventions, 25 qualitative papers and one mixed-methods paper met the criteria for inclusion in this review. Review of the effectiveness literature indicated evidence of positive outcomes across all types of interventions. Virtually all evidence we identified reported at least some positive effect for some participants. However, there was evidence of considerable individual variation in outcome for study participants. The qualitative literature highlighted the need for programmes to be tailored to individual need with variation at the levels of the intervention, the individual and interpersonal/social elements. Metasynthesis of the data highlighted the complexity of elements that need to be considered in evaluation of long-term impacts following stuttering interventions. LIMITATIONS Around two-thirds of the studies were considered to be at higher risk of bias. The heterogeneous nature and variability in outcomes meant that we were unable to complete a meta-analysis. CONCLUSIONS Although much of the evidence we identified was from studies at risk of bias, it is suggested that most available interventions for stuttering may be of benefit to at least some people who stutter. There is a requirement for greater clarity regarding what the core outcomes following stuttering intervention should be and also enhanced understanding of the process whereby interventions effect change. Further analysis of those for whom interventions have not produced a significant benefit may provide additional insights into the complex intervention-outcomes pathway. STUDY REGISTRATION This study is registered as PROSPERO CRD42013004861.

Abstract
Stuttering is a speech disorder, with onset often occurring in the preschool years. The prevalence of stuttering in young children is much higher than that in the general population, suggesting a high rate of recovery. However, we are unable to predict which children will recover without treatment, and it is widely acknowledged that stuttering therapy during childhood provides the best safeguard against chronic stuttering. This review reports on current evidence-based stuttering treatment options for preschoolers through to adolescents. We discuss the clinical challenges associated with treating pediatric clients who stutter at different stages of development and explore potential areas of treatment research that might serve to advance current clinical practice in the future.

Abstract
This article presents a follow-up study to Lee, van Dulm, Robb, and Ormond (2015). The aim was to explore communication restriction in adults with stuttering (AWS) using typical language measures and systemic functional linguistics (SFL) analyses. The article compared the pre- and post-treatment performance of AWS in language productivity and complexity, transitivity, modality, appraisal, and theme. Ten-minute conversational samples were obtained from 20 AWS before and after participation in intensive stuttering treatment. Transcripts were analysed for quantity and complexity of verbal output, and frequency of transitivity, modality, appraisal and theme resources. Between pre- and post-treatment, the following differences were observed: (1) a significant increase in frequency of modal operators, and trends approaching significance for (2) increased language complexity (3) increased language expressing appraisal. These changes suggest increased flexibility of language use in AWS following treatment, particularly towards interpersonal engagement. The value of SFL to this area of research is discussed.

Abstract
PURPOSE This study investigated whether measures of percentage syllables stuttered (%SS) and stuttering severity ratings with a 9-point scale differ when made from audiovisual compared with audio-only recordings. METHOD Four experienced speech-language pathologists measured %SS and assigned stuttering severity ratings to 10-minute audiovisual and audio-only recordings of 36 adults. RESULT There was a mean 18% increase in %SS scores when samples were presented in audiovisual compared with audio-only mode. This result was consistent across both higher and lower %SS scores and was found to be directly attributable to counts of stuttered syllables rather than the total number of syllables. There was no significant difference between stuttering severity ratings made from the two modes. CONCLUSION In clinical trials research, when using %SS as the primary outcome measure, audiovisual samples would be preferred as long as clear, good quality, front-on images can be easily captured. Alternatively, stuttering severity ratings may be a more valid measure to use as they correlate well with %SS and values are not influenced by the presentation mode.

Abstract
Coleman, Miller, and Weidner's (2015) recent clinical vignette and tutorial described one very common, broad-based, and theory-driven approach to treating stuttering in a 14-year-old boy. This response suggests that methods based on prolonged speech are better supported in our research literature; are effective, efficient, and well-received by clients; and allow clinicians using the principles of evidence-based practice to address and solve the concerns that clients have raised.

Part 1: a systematic review of effectiveness. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2015; 50:676-718.

Abstract
BACKGROUND The growing range of available treatment options for people who stutter presents a challenge for clinicians, service managers and commissioners, who need to have access to the best available treatment evidence to guide them in providing the most appropriate interventions. While a number of reviews of interventions for specific populations or a specific type of intervention have been carried out, a broad-based systematic review across all forms of intervention for adults and children was needed to provide evidence to underpin future guidelines, inform the implementation of effective treatments and identify future research priorities. AIMS To identify and synthesize the published research evidence on the clinical effectiveness of the broad range of non-pharmacological interventions for the management of developmental stuttering. METHODS & PROCEDURES A systematic review of the literature reporting interventions for developmental stuttering was carried out between August 2013 and April 2014. Searches were not limited by language or location, but were restricted by date to studies published from 1990 onwards. Methods for the identification of relevant studies included electronic database searching, reference list checking, citation searching and hand searching of key journals. Appraisal of study quality was performed using a tool based on established criteria for considering risk of bias. Due to heterogeneity in intervention content and outcomes, a narrative synthesis was completed. MAIN CONTRIBUTION The review included all available types of intervention and found that most may be of benefit to at least some people who stutter. There was evidence, however, of considerable individual variation in response to these interventions. The review indicated that effects could be maintained following all types of interventions (although this was weakest with regard to feedback and technology interventions). CONCLUSIONS This review highlights a need for greater consensus with regard to the key outcomes used to evaluate stuttering interventions, and also a need for enhanced understanding of the process whereby interventions effect change. Further analysis of the variation in effectiveness for different individuals or groups is needed in order to identify who may benefit most from which intervention.

Abstract
PURPOSE This multiple-baseline across subjects study investigated the effectiveness of video self-modeling (VSM) in reducing stuttering and bringing about improvements in associated self-report measures. Participants' viewing practices and perceptions of the utility of VSM also were explored. METHODS Three adult males who had previously completed speech restructuring treatment viewed VSM recordings twice per week for 6 weeks. Weekly speech data, treatment viewing logs, and pre- and post-treatment self-report measures were obtained. An exit interview also was conducted. RESULTS Two participants showed a decreasing trend in stuttering frequency. All participants appeared to engage in fewer avoidance behaviors and had less expectations to stutter. All participants perceived that, in different ways, the VSM treatment had benefited them and all participants had unique viewing practices. CONCLUSION Given the increasing availability and ease in using portable audio-visual technology, VSM appears to offer an economical and clinically useful tool for clients who are motivated to use the technology to recover fluency. EDUCATIONAL OBJECTIVES Readers will be able to describe: (a) the tenets of video-self modeling; (b) the main components of video-self modeling as a fluency recovery treatment as used in this study; and (c) speech and self-report outcomes.

Abstract
PURPOSE This study compared a new adult stuttering treatment program (Modifying Phonation Intervals, or MPI) with the standard of care for reducing stuttered speech in adults (prolonged speech). METHOD Twenty-seven adults who stutter were assigned to either MPI or prolonged speech treatment, both of which used similar infrastructures. Speech and related variables were assessed in 3 within-clinic and 3 beyond-clinic speaking situations for participants who successfully completed all treatment phases. RESULTS At transfer, maintenance, and follow-up, the speech of 14 participants who successfully completed treatment was similar to that of normally fluent adults. Successful participants also showed increased self-identification as a "normal speaker," decreased self-identification as a "stutterer," reduced short intervals of phonation, and some increased use of longer duration phonation intervals. Eleven successful participants received the MPI treatment, and 3 received the prolonged speech treatment. CONCLUSIONS Outcomes for successful participants were very similar for the 2 treatments. The much larger proportion of successful participants in the MPI group, however, combined with the predictive value of specific changes in PI durations suggest that MPI treatment was relatively more effective at assisting clients to identify and change the specific speech behaviors that are associated with successful treatment of stuttered speech in adults.

Abstract
BACKGROUND Event- and interval-based measurements are two different ways of computing frequency of stuttering. Interval-based methodology emerged as an alternative measure to overcome problems associated with reproducibility in the event-based methodology. No review has been made to study the effect of methodological factors in interval-based absolute reliability data or to compute the agreement between the two methodologies in terms of inter-judge, intra-judge and accuracy (i.e., correspondence between raters' scores and an established criterion). AIMS To provide a review related to reproducibility of event-based and time-interval measurement, and to verify the effect of methodological factors (training, experience, interval duration, sample presentation order and judgment conditions) on agreement of time-interval measurement; in addition, to determine if it is possible to quantify the agreement between the two methodologies METHODS & PROCEDURES The first two authors searched for articles on ERIC, MEDLINE, PubMed, B-on, CENTRAL and Dissertation Abstracts during January-February 2013 and retrieved 495 articles. Forty-eight articles were selected for review. Content tables were constructed with the main findings. MAIN CONTRIBUTION Articles related to event-based measurements revealed values of inter- and intra-judge greater than 0.70 and agreement percentages beyond 80%. The articles related to time-interval measures revealed that, in general, judges with more experience with stuttering presented significantly higher levels of intra- and inter-judge agreement. Inter- and intra-judge values were beyond the references for high reproducibility values for both methodologies. Accuracy (regarding the closeness of raters' judgements with an established criterion), intra- and inter-judge agreement were higher for trained groups when compared with non-trained groups. Sample presentation order and audio/video conditions did not result in differences in inter- or intra-judge results. A duration of 5 s for an interval appears to be an acceptable agreement. Explanation for high reproducibility values as well as parameter choice to report those data are discussed. CONCLUSIONS & IMPLICATIONS Both interval- and event-based methodologies used trained or experienced judges for inter- and intra-judge determination and data were beyond the references for good reproducibility values. Inter- and intra-judge values were reported in different metric scales among event- and interval-based methods studies, making it unfeasible to quantify the agreement between the two methods.

Abstract
PURPOSE Percentage of syllables stuttered (%SS) and severity rating (SR) scales are measures in common use to quantify stuttering severity and its changes during basic and clinical research conditions. However, their reliability has not been assessed with indices measuring both relative and absolute reliability. This study was designed to provide such information. Relative reliability deals with the rank order of participants in a sample, whereas absolute reliability measures the closeness of scores to one other and to a hypothetical true score. METHOD Eighty-seven adult participants who stutter received a 10-min unscheduled telephone call. Three experienced judges measured %SS and also used a 9-point SR scale to measure stuttering severity from recordings of the telephone calls. RESULTS Relative intrajudge and interjudge reliability were satisfactory for both scales. However, absolute intrajudge and interjudge reliability were not satisfactory. Results showed that paired-judge SR and %SS procedures improved absolute reliability compared with single-judge measures. Additionally, the paired-judge procedure improved relative reliability from high to very high levels. CONCLUSION Measurement of group changes of stuttering severity can be done in research contexts using either %SS or SR. However, for detecting changes within individuals using such measures, a paired-judge procedure is a more reliable method.

Abstract
PURPOSE Researchers have used unscheduled telephone calls for many years during clinical trials to measure adult stuttering severity before and after treatment. Because variability is a hallmark of stuttering severity with adults, it is questionable whether an unscheduled telephone call is truly representative of their everyday speech. METHOD The authors studied the speech of 9 men and 1 woman for a 12-hr day during different speaking activities. On that day and 1 week prior to that day, participants received an unscheduled 10-min telephone call from a person unknown to them. The authors compared the percent syllables stuttered (%SS) for the unscheduled telephone call on the day to the %SS of the unscheduled telephone call 1 week prior to the day and to the %SS during the entire day. RESULTS No significant differences were found, and all confidence intervals with t tests included 0. The concordance correlation test also showed a strong positive correlation between %SS scores for the entire day and for the unscheduled 10-min telephone call. CONCLUSION The authors conclude that there is no reason to doubt that 10-min unscheduled telephone calls are a representative speech sample for %SS during clinical trials of stuttering treatments.

Abstract
Objetivo : comparar a fluência de crianças com gagueira quanto à porcentagem de sílabas gaguejadas, porcentagem de descontinuidade da fala, fluxo de sílabas e palavras por minuto e gravidade da gagueira, em situação de pré e pós-aplicação do programa de intervenção fonoaudiológica. Método : participaram 10 crianças, na faixa etária de 6.0 a 11.11 anos, sendo 9 do gênero masculino e 1 do gênero feminino, provenientes do Laboratório de Estudos da Fluência. Todos os participantes deste estudo foram submetidos aos seguintes procedimentos agrupados em três etapas: (a) avaliação da fluência inicial; (b) desenvolvimento do processo terapêutico, e; (c) reavaliação da fluência. Resultados : em relação à avaliação após o programa terapêutico, observou-se uma melhora relevante no perfil da fluência, pois a maioria das medidas analisadas (descontinuidade de fala, disfluências gagas, fluxo de sílabas por minuto e gravidade da gagueira) apresentou diferenças estatisticamente significantes. Os achados indicaram que houve uma redução quantitativa nas rupturas o que ocasionou um aumento no fluxo de sílabas por minuto, e também uma diminuição na gravidade da gagueira. Estes resultados confirmam a eficácia terapêutica do programa de terapia aplicado. Conclusão : os resultados encontrados podem auxiliar o fonoaudiólogo em sua prática clínica, tanto na terapia como na realização do diagnóstico e do controle da eficácia terapêutica.

Abstract
UNLABELLED The BigCAT and the Erickson S-24, self-report measures of communication attitude, were administered in a randomly determined order to 72 adults who stuttered (PWS) and 72 who did not (PWNS). The two groups of participants differed from each other to a statistically significant extent on both of these measures of speech-associated attitude, regardless of gender. However, the BigCAT showed a larger between-group difference and a greater effect size than was made apparent by the S-24. These findings, and the presence of a significant group by test interaction, suggest that the BigCAT is the more powerful of these two test procedures for discriminating the speech-associated attitude of PWS from that of PWNS. It follows from this that the BigCAT is likely a more useful attitudinal measure than the S-24 with respect to clinical decision making that relates to differential diagnostic assessment and the management of stuttering. LEARNING OUTCOMES The reader will be (1) describe the BigCAT, a communication attitude test for adults who do and do not stutter, (2) discuss comparative data on the BigCAT and the Erickson S-24, based on information on the discriminative power of these measures of speech-associated attitude, (3) recognize that gender does not significantly effect the results of either the BigCAT or the Erickson S-24.

Abstract
PURPOSE It is proposed that stuttering treatment, particularly for adults and adolescents who stutter, may benefit from more inventive and extensive use of functional measurement-measures that are also treatment agents. Such measures can be tailored to produce more personally significant and evidence-based treatment benefits. They may be especially useful when employed in conjunction with partial self-management and performance-contingent procedures. METHOD Previous approaches to the definition of stuttering treatment goals and the measurement of stuttering treatment outcomes are critically reviewed. Suggestions for improvements are presented within the framework of an evidence-based and relatively standardized stuttering treatment. RESULTS AND CONCLUSION Results from a review of existing literature and from 2 case studies show that 2 specific personally significant problems, saying one's name and addressing large audiences, were improved by implementing these strategies in treatment. Functional measures directly connected to treatment, and partially self-managed performance-contingent schedules, merit further research as methodologies that are suitable for conducting personally significant and evidence-based treatments with adults and adolescents who stutter.

Abstract
Purpose
This Phase I clinical trial explored the viability of webcam Internet delivery of the Camperdown Program for adolescents who stutter.
Method and Procedure
Participants were 3 adolescents ages 13, 15, and 16 years, with moderate-severe stuttering. Each was treated with the Camperdown Program delivered by webcam with no clinic attendance. Primary outcome measures were percentage of syllables stuttered and number of treatment sessions to maintenance. Secondary outcome measures were speech naturalness, situation avoidance, self-reported stuttering severity, and parent and adolescent satisfaction. Data were collected pre treatment and at 1 day, 6 months, and 12 months post entry to maintenance.
Results
Participants entered maintenance after means of 18 sessions and 11 clinician hours. Group mean reduction of stuttering from pre treatment to entry to maintenance was 83%, from pre treatment to 6 months post entry to maintenance was 93%, and from pre treatment to 12 months post entry to maintenance was 74%. Self-reported stuttering severity ratings confirmed these results. Post entry to maintenance speech naturalness for participants fell within the range of that of 3 matched controls. However, avoidance of speech situations showed no corresponding improvements for 2 of the participants.
Conclusion
The service delivery model was efficacious and efficient. All of the participants and their parents also found it appealing. Results justify a Phase II trial of the delivery model.

[PMID: 22325920 DOI: 10.1016/j.jfludis.2011.11.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/20/2010] [Revised: 11/14/2011] [Accepted: 11/14/2011] [Indexed: 05/31/2023]
Abstract
UNLABELLED Factors affecting perceptions of occupational suitability were examined for speakers who stutter and speakers who do not stutter. In Experiment 1, 58 adults who do not stutter heard one of two audio recordings (less severe stuttering, more severe stuttering) of a speaker who stuttered. Participants rated the speaker's communicative functioning, personal attributes, and suitability for 32 occupations, along with perceptions of the occupations' speaking demands and educational requirements. Perceived speaking demand strongly affected occupational suitability ratings at both levels of stuttering severity. In Experiment 2, 58 additional adults who do not stutter heard a recording of another adult in one of two conditions (fluent speech, pseudo-stuttering), and provided the same ratings as in Experiment 1. In the pseudo-stuttering condition, participants' perceptions of occupational speaking demand again had a strong effect on occupational suitability ratings. In the fluent condition, suitability ratings were affected primarily by perceived educational demand; perceived speaking demand was of secondary importance. Across all participants in Experiment 2, occupational suitability ratings were associated with ratings of the speaker's personal attributes and communicative functioning. In both experiments, speakers who stuttered received lower suitability ratings for high speaking demand occupations than for low speaking demand occupations. Ratings for many high speaking occupations, however, fell just below the midpoint of the occupational suitability scale, suggesting that participants viewed these occupations as less appropriate, but not necessarily inappropriate, for people who stutter. Overall, the findings support the hypothesis that people who stutter may face occupational stereotyping and/or role entrapment in work settings. EDUCATIONAL OBJECTIVES At the end of this activity the reader will be able to (a) summarize main findings on research related to the work-related experiences of people who stutter, (b) describe factors that affect perceptions of which occupations are best suited for speakers who stutter and speakers who do not stutter, and (c) discuss how findings from the present study relate to previous findings on occupational advice for people who stutter.
