Caughter S, Dunsmuir S. An exploration of the mechanisms of change following an integrated group intervention for stuttering, as perceived by school-aged children who stutter (CWS). JOURNAL OF FLUENCY DISORDERS 2017; 51:8-23. [PMID: 28212721 DOI: 10.1016/j.jfludis.2016.10.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/29/2016] [Revised: 10/07/2016] [Accepted: 10/24/2016] [Indexed: 06/06/2023]
Abstract
PURPOSE To explore the process of change and role of resilience following an integrated group intervention for children who stutter (CWS). METHOD Using an exploratory multiple case study design, this research sought to identify the most significant changes perceived by seven participants following therapy, the mechanisms of change, and the role of resilience in the process of change. Quantitative measurements of resilience were combined with qualitative analysis of semi-structured interviews. RESULTS Thematic analysis of qualitative data showed that cognitive and emotional change was a key driver for therapeutic change, enabled by the shared experience of the group and a positive therapeutic environment. These changes were generalised into clients' real-world experiences, facilitated by their support network. Quantitative data demonstrated a statistically reliable positive change in overall Resiliency scores for four participants and reduced impact of stuttering scores on OASES-S for all participants, maintained at 12 month follow-up. CONCLUSIONS This study demonstrates the importance of adopting an integrated approach in therapy for CWS, which incorporates Cognitive Behavioural Therapy (CBT) as a key component, to facilitate change and build resilience. These results are unique to this cohort of CWS and further investigation into the use of CBT and the process of change may be warranted. EDUCATIONAL OBJECTIVES The reader will be able to (1) describe the integrated intervention used in this study (2) define the most significant change following therapy for the participants involved (3) summarise the key factors that facilitated change during the therapy process (as perceived by the participants).

Abstract
PURPOSE To describe the language development in a sample of young children who stutter during the first 12 months after stuttering onset was reported. METHODS Language production was analysed in a sample of 66 children who stuttered (aged 2-4 years). The sample were identified from a pre-existing prospective, community based longitudinal cohort. Data were collected at three time points within the first year after stuttering onset. Stuttering severity was measured, and global indicators of expressive language proficiency (length of utterances and grammatical complexity) were derived from the samples and summarised. Language production abilities of the children who stutter were contrasted with normative data. RESULTS The majority of children's stuttering was rated as mild in severity, with more than 83% of participants demonstrating very mild or mild stuttering at each of the time points studied. The participants demonstrated developmentally appropriate spoken language skills comparable with available normative data. CONCLUSION In the first year following the report of stuttering onset, the language skills of the children who were stuttering progressed in a manner that is consistent with developmental expectations.

Abstract
Adults who stutter can learn to control and improve their speech fluency by modifying their speaking rate. Existing speech therapy technologies can assist this practice by monitoring speaking rate and providing feedback to the patient, but cannot provide an accurate, quantitative measurement of speaking rate. Moreover, most technologies are too complex and costly to be used for home practice. We developed an algorithm and a smartphone application that monitor a patient's speaking rate in real time and provide user-friendly feedback to both patient and therapist. Our speaking rate computation is performed by a phoneme counting algorithm which implements spectral transition measure extraction to estimate phoneme boundaries. The algorithm is implemented in real time in a mobile application that presents its results in a user-friendly interface. The application incorporates two modes: one provides the patient with visual feedback of his/her speech rate for self-practice and another provides the speech therapist with recordings, speech rate analysis and tools to manage the patient's practice. The algorithm's phoneme counting accuracy was validated on ten healthy subjects who read a paragraph at slow, normal and fast paces, and was compared to manual counting of speech experts. Test-retest and intra-counter reliability were assessed. Preliminary results indicate differences of -4% to 11% between automatic and human phoneme counting. Differences were largest for slow speech. The application can thus provide reliable, user-friendly, real-time feedback for speaking rate control practice.

Abstract
PURPOSE This study surveyed didactic and clinical education in fluency disorders at undergraduate and graduate institutions in the United States that provide education in speech-language pathology to determine whether a previously observed reduction in requirements has continued since prior surveys (Yaruss, 1999; Yaruss & Quesal, 2002). METHOD The study involved a detailed questionnaire that was sent to 282 communication science and disorders departments. Questions examined didactic and clinical education, as well as faculty knowledge about fluency disorders. RESULTS Comparisons with prior surveys revealed several findings, including (a) on average, programs have increased academic coursework and incorporated more practical sessions and competency-based testing in the classroom; (b) the number of faculty who possess extensive clinical experience with fluency disorders has decreased; and (c) although an increase in clinical requirements in fluency disorders was detected, the number of programs providing minimal education about fluency disorders remains high. CONCLUSION Given an expanding scope of practice, many programs have continued to try to provide adequate education about fluency disorders. Still, direct clinical experiences are limited, and faculty expertise in this area has continued to decrease. To raise students' confidence and competence in fluency disorders, efforts beyond graduate work-or systemic changes in the profession-may be necessary.

Abstract
PURPOSE The dual diathesis stressor model indicates that a mismatch between a child's endogenous linguistic abilities and exogenous linguistic contexts is one factor that contributes to stuttering behavior. In the present study, we used a developmental framework to investigate if reducing the gap between endogenous and exogenous linguistics factors would result in less disfluency for typical children, children who recover from stuttering (CWS-R), and children who persist. METHOD Children between 28 and 43 months of age participated in this study: 8 typical children, 5 CWS-R, and 8 children who persist. The children were followed for 18 months with language samples collected every 6 months. The Index of Productive Syntax (Scarborough, 1990) served as a measure of endogenous grammatical ability. Length and complexity of active declarative sentences served as a measure of exogenous linguistic demand. A hierarchical linear model analysis was conducted using a mixed-model approach. RESULTS The results partially corroborate the dual diathesis stressor model. Disfluencies significantly decreased in CWS-R as grammatical abilities (not age) increased. Language development may serve as a protective factor or catalyst for recovery for CWS-R. As grammatical ability grew and the gap between linguistic ability and demand decreased; however, none of the three groups was more likely to produce disfluencies in longer and more complex utterances.

Abstract
PURPOSE The purpose of this study was to examine the influence of self-disclosure on observers' perceptions of persons who stutter. METHOD Participants (N = 173) were randomly assigned to view 2 of 4 possible videos (i.e., male self-disclosure, male no self-disclosure, female self-disclosure, and female no self-disclosure). After viewing both videos, participants completed a survey assessing their perceptions of the speakers. RESULTS Controlling for observer and speaker gender, listeners were more likely to select speakers who self-disclosed their stuttering as more friendly, outgoing, and confident compared with speakers who did not self-disclose. Observers were more likely to select speakers who did not self-disclose as unfriendly and shy compared with speakers who used a self-disclosure statement. Controlling for self-disclosure and observer gender, observers were less likely to choose the female speaker as friendlier, outgoing, and confident compared with the male speaker. Observers also were more likely to select the female speaker as unfriendly, shy, unintelligent, and insecure compared with the male speaker and were more likely to report that they were more distracted when viewing the videos. CONCLUSION Results lend support to the effectiveness of self-disclosure as a technique that persons who stutter can use to positively influence the perceptions of listeners.

Abstract
Developmental stuttering is a disorder of speech fluency affecting 1% of the adult population. Long-term reductions in stuttering are difficult for adults to achieve with behavioural therapies. We investigated whether a single session of transcranial direct current stimulation (TDCS) could improve fluency in people who stutter (PWS). In separate sessions, either anodal TDCS (1mA for 20min) or sham stimulation was applied over the left inferior frontal cortex while PWS read sentences aloud. Fluency was induced during the stimulation period by using choral speech, that is, participants read in unison with another speaker. Stuttering frequency during sentence reading, paragraph reading and conversation was measured at baseline and at two outcome time points: immediately after the stimulation period and 1h later. Stuttering was reduced significantly at both outcome time points for the sentence-reading task, presumably due to practice, but not during the paragraph reading or conversation tasks. None of the outcome measures were significantly modulated by anodal TDCS. Although the results of this single-session study showed no significant TDCS-induced improvements in fluency, there were some indications that further research is warranted. We discuss factors that we believe may have obscured the expected positive effects of TDCS on fluency, such as heterogeneity in stuttering severity for the sample and variations across sessions. Consideration of such factors may inform future studies aimed at determining the potential of TDCS in the treatment of developmental stuttering.

Abstract
PURPOSE To investigate the validity of findings from a recent study reported in this journal by de Sonneville-Koedoot, Bouwmans, Franken, and Stolk (2015) on the cost effectiveness of two programs for treating young children who stutter. METHODS The de Sonneville-Koedoot, Bouwmans et al. study was based directly on the results obtained in an earlier study, known as the RESTART-study, which compared the outcomes from the Lidcombe Program and a Demands and Capacities Model program. The methodology of the RESTART-study was critically reviewed. RESULTS The absence of an untreated control group in the RESTART-study makes the results of that study uninterpretable. An inappropriate comparison made with the Yairi and Ambrose (2005) Illinois Study findings failed to resolve the control group problem. Furthermore, the criteria used to classify treated children as "non-stuttering" was also shown to be confounded. The foregoing problems meant that neither treatment program could be shown to be more effective than no treatment. CONCLUSION de Sonneville-Koedoot, Bouwmans et al's findings, which compared the cost effectiveness of two treatments for young children who stutter, have no value for clinical management because the treatments investigated were not shown to be more effective than no treatment.

Abstract
A case study of DW, an 11-yr. old monolingual, English-speaking boy who exhibits stuttering, language delay, and ADHD is presented. DW experienced only limited improvement during stuttering therapy received in public schools, according to parents and the public school clinician. The purpose of this case study was to assess whether fluency treatment which incorporated Mediated Learning, Delayed Auditory Feedback, and Speech Motor Repatterning would enhance progress. Therapy was delivered in two treatments, with each treatment being 5 wk. of intense therapy, separated by one year. Treatment 1 of combined Mediated Learning and Delayed Auditory Feedback yielded improvement in fluency, judged by parents and the teacher to be clinically significant. The improved fluency was maintained for one year when DW was pretested for participation in Treatment 2, which combined Mediated Learning, Delayed Auditory Feedback, and Speech Motor Repatterning Exercises. As no conclusions are possible, further study is needed.

Abstract
PURPOSE Virtual reality environments (VREs) allow for immersion in speaking environments that mimic real-life interactions while maintaining researcher control. VREs have been used successfully to engender arousal in other disorders. The purpose of this study was to investigate the utility of virtual reality environments to examine physiological reactivity and subjective ratings of distress in persons who stutter (PWS). METHOD Subjective and objective measures of arousal were collected from 10PWS during four-minute speeches to a virtual audience and to a virtual empty room. RESULTS Stuttering frequency and physiological measures (skin conductance level and heart rate) did not differ across speaking conditions, but subjective ratings of distress were significantly higher in the virtual audience condition compared to the virtual empty room. CONCLUSION VREs have utility in elevating subjective ratings of distress in PWS. VREs have the potential to be useful tools for practicing treatment targets in a safe, controlled, and systematic manner.

Abstract
PURPOSE The purpose of this study was to investigate whether stuttering reductions following the instatement phase of a speech-restructuring treatment for adults were accompanied by reductions in the frequency of short intervals of phonation (PIs). The study was prompted by the possibility that reductions in the frequency of short PIs is the mechanism underlying such reductions in stuttering. METHOD The distribution of PIs was determined for seven adults who stutter, before and immediately after the intensive phase of a speech-restructuring treatment program. Audiovisual recordings of conversational speech were made on both assessment occasions, with PIs recorded with an accelerometer. RESULTS All seven participants had much lower levels of stuttering after treatment but these were associated with reductions in the frequency of short PIs for only four of them. For the other three participants, two showed no change in frequency of short PIs, while for the other participant the frequency of short PIs actually increased. CONCLUSIONS Stuttering reduction with speech-restructuring treatment can co-occur with reduction in the frequency of short PIs. However, the latter does not appear necessary for this reduction in stuttering to occur. Thus, speech-restructuring treatment must have other, or additional, treatment agents for stuttering to reduce.

Abstract
BACKGROUND Numerous studies have demonstrated the benefit of devices delivering altered auditory feedback (AAF) as a therapeutic alternative for those who stutter. AIMS The effectiveness of a device delivering AAF (SpeechEasy®) was compared with behavioural techniques in the treatment of stuttering in a randomized clinical trial. METHODS & PROCEDURES Two groups of adults who stutter participated: group 1 consisted of 10 men and one woman aged 21-42 years (mean = 30.0). Group 2 consisted of six men and one woman aged 20-50 years (mean = 35.6). Participants in group 1 were fit with a SpeechEasy® device and were not given any additional training (i.e., supplementary fluency enhancing techniques). Participants used the device daily for 6 months. Participants in group 2 received treatment in the form of a 12-week fluency promotion protocol with techniques based on both fluency shaping and stuttering modification. OUTCOMES & RESULTS There were no statistically significant differences (p > .05) between groups in participants' stuttered syllables following treatment. That is, both therapeutic protocols achieved approximately 40% reduction in number of stuttered syllables from baseline measures, with no significant relapse after 3 or 6 months post-treatment. CONCLUSIONS & IMPLICATIONS The results suggest that the SpeechEasy® device can be a viable option for the treatment of stuttering.

Abstract
PURPOSE The goal of this study is to explore the psychometric properties of the Parent Rating Scales-V1 (S. K. Millard, S. Edwards, & F. M. Cook, 2009), an assessment tool for parents of children who stutter, and to refine the measure accordingly. METHOD We included 259 scales completed prior to therapy. An exploratory factor analysis determined the test constructs and identified the items that had greatest loadings on those factors. Items that did not load on the factors were removed, and normative scores calculated. RESULTS The resulting 19-item questionnaire measures three factors: (a) the impact of stuttering on the child; (b) the severity of stuttering and its impact on the parents; and (c) the parents' knowledge about stuttering and confidence in managing it. Reliability was demonstrated, norms established, and an automated online version constructed. CONCLUSIONS The Palin Parent Rating Scale is a valid and reliable tool, providing a method of exploring parents' perceptions of stuttering, the impact it has on the child and themselves, and the parents' knowledge of and confidence in managing the stuttering. This is an important addition to the existing range of assessments that may be used to evaluate stuttering in children up to age 14;6 (years;months) and allows the wider targets of parent-led therapy programs to be evaluated.

Abstract
PURPOSE Webcam treatment is potentially useful for health care in cases of early stuttering in which clients are isolated from specialized treatment services for geographic and other reasons. The purpose of the present trial was to compare outcomes of clinic and webcam deliveries of the Lidcombe Program treatment (Packman et al., 2015) for early stuttering. METHOD The design was a parallel, open plan, noninferiority randomized controlled trial of the standard Lidcombe Program treatment and the experimental webcam Lidcombe Program treatment. Participants were 49 children aged 3 years 0 months to 5 years 11 months at the start of treatment. Primary outcomes were the percentage of syllables stuttered at 9 months postrandomization and the number of consultations to complete Stage 1 of the Lidcombe Program. RESULTS There was insufficient evidence of a posttreatment difference of the percentage of syllables stuttered between the standard and webcam Lidcombe Program treatments. There was insufficient evidence of a difference between the groups for typical stuttering severity measured by parents or the reported clinical relationship with the treating speech-language pathologist. CONCLUSIONS This trial confirmed the viability of the webcam Lidcombe Program intervention. It appears to be as efficacious and economically viable as the standard, clinic Lidcombe Program treatment.

Abstract
PURPOSE This study investigated the outcomes of implementing the Lidcombe Program, an evidence-based early intervention for stuttering, with four preschool children in Malaysia. Early stuttering intervention is currently underdeveloped in Malaysia, where stuttering treatment is often more assertion-based than evidence-based. Therefore, introducing an evidence-based early stuttering intervention is an important milestone for Malaysian preschoolers who stutter. METHOD The participants ranged from 3 years 3 months to 4 years 9 months at the start of the study. Beyond-clinic speech samples were obtained at 1 month and 1 week pretreatment and immediately post-Stage 1, and at 1 month, 3 months, 6 months and 12 months post-Stage 1. RESULTS Two participants, who were bilingual, achieved near-zero levels of stuttering at 12 months posttreatment. Near zero levels of stuttering were also present in their untreated languages. One participant withdrew due to reasons not connected with the research or treatment. The remaining participant, who presented with severe stuttering, completed Stage 1 but had some relapse in Stage 2 and demonstrated mild stuttering 12 months post-Stage 1. CONCLUSIONS The outcomes were achieved without the need to significantly adapt Lidcombe Program procedures to Malaysian culture. Further research to continue evaluation of the Lidcombe Program with Malaysian families and to estimate proportion of those who will respond is warranted.

Abstract
PURPOSE This Phase I trial reports the results of a clinician-free Internet speech restructuring treatment for adults who stutter. The program consists of nine phases with concepts loosely based on the Camperdown Program. METHOD Twenty adults who stutter were recruited. They were given unlimited access to the program for 6 months. Primary outcome measures were the percentage of syllables stuttered and self-reported severity ratings. RESULT Five participants accessed all phases of the program, while another five accessed more than half the phases. The remaining 10 accessed between one and four phases. Four of five participants who accessed all phases reduced their stuttering frequency by more than 50% and an additional two participants who accessed more than half the phases also achieved similar reductions. These results were confirmed by self-reports of stuttering severity. Stuttering reductions were largely commensurate with the amount of the program accessed. CONCLUSION As with other clinician-free programs in related health areas, maintaining adherence to the program's procedures was a significant issue. Nonetheless, this novel approach to treating stuttering has the potential to be a viable alternative for some clients and may help to address the significant access and relapse issues that affect treatment provision for adults who stutter.

Abstract
UNLABELLED Singing has long been used as a technique to enhance and reeducate temporal aspects of articulation in speech disorders. In the present study, differences in temporal structure of sung versus spoken speech were investigated in stuttering. In particular, the question was examined if singing helps to reduce VOT variability of voiceless plosives, which would indicate enhanced temporal coordination of oral and laryngeal processes. Eight German adolescents who stutter and eight typically fluent peers repeatedly spoke and sang a simple German congratulation formula in which a disyllabic target word (e.g., /'ki:ta/) was repeated five times. Every trial, the first syllable of the word was varied starting equally often with one of the three voiceless German stops /p/, /t/, /k/. Acoustic analyses showed that mean VOT and stop gap duration reduced during singing compared to speaking while mean vowel and utterance duration was prolonged in singing in both groups. Importantly, adolescents who stutter significantly reduced VOT variability (measured as the Coefficient of Variation) during sung productions compared to speaking in word-initial stressed positions while the control group showed a slight increase in VOT variability. However, in unstressed syllables, VOT variability increased in both adolescents who do and do not stutter from speech to song. In addition, vowel and utterance durational variability decreased in both groups, yet, adolescents who stutter were still more variable in utterance duration independent of the form of vocalization. These findings shed new light on how singing alters temporal structure and in particular, the coordination of laryngeal-oral timing in stuttering. Future perspectives for investigating how rhythmic aspects could aid the management of fluent speech in stuttering are discussed. LEARNING OUTCOMES Readers will be able to describe (1) current perspectives on singing and its effects on articulation and fluency in stuttering and (2) acoustic parameters such as VOT variability which indicate the efficiency of control and coordination of laryngeal-oral movements. They will understand and be able to discuss (3) how singing reduces temporal variability in the productions of adolescents who do and do not stutter and 4) how this is linked to altered articulatory patterns in singing as well as to its rhythmic structure.

Abstract
This evaluative study assessed the feasibility and outcome of delivering speech–language services from a distance to children and adolescents who stutter. All six patients who formed the first cohort seen in the telespeech programme were included in the study. The results demonstrated that interactive videoconferencing can provide a feasible and effective care delivery model. Patient attendance was maintained throughout the intervention. All participants showed improved fluency. Stuttering ranged from 13% to 36% before treatment and 2% to 26% after treatment. All participants maintained at least part of their improved fluency during the six-month follow-up, when stuttering ranged from 4% to 32%. The study demonstrates that full assessment and treatment of stuttering in children and adolescents can be accomplished successfully via telemedicine.

Abstract
PURPOSE A recent clinical trial (Andrews et al., 2012) showed Syllable Timed Speech (STS) to be a potentially useful treatment agent for the reduction of stuttering for school-age children. The present trial investigated a modified version of this program that incorporated parent verbal contingencies. METHODS Participants were 22 stuttering children aged 6-11 years. Treatment involved training the children and their parents to use STS in conversation. Parents were also taught to use verbal contingencies in response to their child's stuttered and stutter-free speech and to praise their child's use of STS. Outcome assessments were conducted pre-treatment, at the completion of Stage 1 of the program and 6 months and 12 months after Stage 1 completion. RESULTS Outcomes are reported for the 19 children who completed Stage 1 of the program. The group mean percent stuttering reduction was 77% from pre-treatment to 12 months post-treatment, and 82% with the two least responsive participants removed. There was considerable variation in response to the treatment. Eleven of the children showed reduced avoidance of speaking situations and 18 were more satisfied with their fluency post-treatment. However, there was some suggestion that stuttering control was not sufficient to fully eliminate situation avoidance for the children. CONCLUSIONS The results of this trial are sufficiently encouraging to warrant further clinical trials of the method.

Abstract
OBJECTIVE To provide an update on the epidemiology, genetics, pathophysiology, diagnosis, and treatment of developmental stuttering. QUALITY OF EVIDENCE The MEDLINE and Cochrane databases were searched for past and recent studies on the epidemiology, genetics, pathophysiology, diagnosis, and treatment of developmental stuttering. Most recommendations are based on small studies, limited-quality evidence, or consensus. MAIN MESSAGE Stuttering is a speech disorder, common in persons of all ages, that affects normal fluency and time patterning of speech. Stuttering has been associated with differences in brain anatomy, functioning, and dopamine regulation thought to be due to genetic causes. Attention to making a correct diagnosis or referral in children is important because there is growing consensus that early intervention with speech therapy for children who stutter is critical. For adults, stuttering can be associated with substantial psychosocial morbidity including social anxiety and low quality of life. Pharmacologic treatment has received attention in recent years, but clinical evidence is limited. The mainstay of treatment for children and adults remains speech therapy. CONCLUSION A growing body of research has attempted to uncover the pathophysiology of stuttering. Referral for speech therapy remains the best option for children and adults.

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 explored the relationship between self-acceptance of stuttering and (1) psychosocial factors (self-esteem, hostility towards others, emotional support, and perceived discrimination); (2) treatment history (support group participation, therapy duration, and perceived therapy success); and (3) previously reported variables in self-acceptance of stuttering, which include age and stuttering severity. METHOD Participants were 80 adults who stutter who were recruited with assistance from the National Stuttering Association and Board Certified Specialists in Fluency Disorders. Participants completed an electronic survey composed of an acceptance of stuttering scale, psychosocial scales, and a participant information questionnaire. RESULTS Statistical analysis identified significant correlations between participants' reports of self-acceptance of stuttering and self-esteem, perceived discrimination, hostility towards others, and perceived therapy outcome. Self-esteem was positively correlated with self-acceptance, while hostility towards others and perceived discrimination was negatively correlated with self-acceptance. Participants who perceived their therapy outcome to be successful were significantly more likely to report higher levels of self-acceptance. No significant relationships were found between self-acceptance of stuttering and support group participation, emotional support, stuttering severity, and participant age. CONCLUSION This exploratory investigation has provided a foundation for future studies on the self-acceptance of stuttering. The findings indicate common psychosocial variables in self-acceptance of stuttering and of other disabilities. The significant relationships between self-acceptance of stuttering and psychosocial and therapeutic variables found need to be further explored to identify its causalities and clinical implications. LEARNING OUTCOMES The reader will be able to (1) discuss the importance of assessing self-acceptance of stuttering, (2) summarize the literature on self-acceptance of disability, and (3) describe the significant findings related to self-acceptance of stuttering and psychosocial, therapeutic variables.

Abstract
PURPOSE The purpose of this study was to document parent presentation of the Lidcombe Program verbal contingencies and model potential relationships between contingency provision and treatment duration. METHODS Forty parent-child pairs undertaking the Lidcombe Program participated, 26 of whom completed Stage 1. All participants were included in the analyses. Parents completed weekly audio-recordings of treatment during practice sessions and a diary of treatment during natural conversations. The number and types of contingencies provided during practice sessions were counted for 520 recordings. Accelerated failure time modeling was used to investigate associations between contingency provision during the first 4 weeks of treatment and duration of time to complete Stage 1. RESULTS During practice sessions 91% of contingencies were for stutter-free speech, 6.8% were for stuttering and 2.7% were incorrectly applied. Parents often combined several verbal contingencies into one. During natural conversations, the number of verbal contingencies reportedly provided across the day was low, an average of 8.5 (SD=7.82) contingencies for stutter-free speech and 1.7 (SD=2.43) for unambiguous stuttering. There was a positive, significant relationship between the number of verbal contingencies for stuttering provided during the first 4 weeks of treatment and time taken to complete Stage 1. CONCLUSION Parents mostly provided the expected types of contingencies but the number was lower than expected. An unexpected association was found between number of verbal contingencies for stuttering and treatment duration. Further research is required to explore the relation between rates of parent verbal contingencies, treatment process duration, and treatment outcome.

Abstract
PURPOSE The purpose of this study was to investigate the use of bibliotherapy as a therapeutic tool for adults who stutter (AWS) and as an educational tool for graduate students in speech-language pathology. Bibliotherapy refers to the process of reading, reflecting upon, and discussing literature, often first person illness or disability narratives, to promote cognitive shifts in the way clients and clinicians conceptualize the experience of disability. METHOD Five AWS and six graduate students participated in supervised bibliotherapy using a stuttering memoir during therapy sessions. An inductive, qualitative analysis was utilized to analyze data collected from questionnaires and interviews. An additional deductive qualitative approach was utilized to explore how client data fit into an existing five-outcome model of bibliotherapy from the psychology literature. RESULTS Graduate students reported developing essential clinical skills for working with clients who stutter, including an improved understanding of the experience of people who stutter and an increased ability to form and strengthen the therapeutic alliance. Clients reported experiencing shifts in the cognitive and affective components of the disorder. Imposing the five-outcome model on client data indicates that at least two clients in the current study experienced all five outcomes of bibliotherapy. These include client experiences of involvement, identification, catharsis, insight and universalism. CONCLUSION Both graduate students and clients reported benefits from reading and discussing a memoir about stuttering. Bibliotherapy can be an effective tool in therapy and clinical education when used appropriately.

Abstract
Extreme prolongations, which can be generated via extreme delayed auditory feedback (DAF) (e.g., 250-500 ms) or mediated cognitively with timing applications (e.g., analog stopwatch) at 2 s per syllable, have long been behavioral techniques used to inhibit stuttering. Some therapies have used this rate solely to establish initial fluency, while others use extremely slowed speech to establish fluency and add other strategic techniques such as easy onsets and diaphragmatic breathing. Extreme prolongations generate effective, efficient, and immediate forward flowing fluent speech, removing the signature behaviors of discrete stuttering (i.e., syllable repetitions and audible and inaudible postural fixations). Prolonged use of extreme prolongations establishes carry-over fluency, which is spontaneous, effortless speech absent of most, if not all, overt and covert manifestations of stuttering. The creation of this immediate fluency and the immense potential of extreme prolongations to generate long periods of carry-over fluency have been overlooked by researchers and clinicians alike. Clinicians depart from these longer prolongation durations as they attempt to achieve the same fluent results at a near normal rate of speech. Clinicians assume they are re-teaching fluency and slow rates will give rise to more normal rates with less control, but without carry-over fluency, controls and cognitive mediation are always needed for the inherently unstable speech systems of persons who stutter to experience fluent speech. The assumption being that the speech system is untenable without some level of cognitive and motoric monitoring that is always necessary. The goal is omnipresent "near normal rate sounding fluency" with continuous mediation via cognitive and motoric processes. This pursuit of "normal sounding fluency" continues despite ever-present relapse. Relapse has become so common that acceptance of stuttering is the new therapy modality because relapse has come to be understood as somewhat inevitable. Researchers and clinicians fail to recognize that immediate amelioration of stuttering and its attendant carry-over fluency are signs of a different pathway to fluency. In this path, clinicians focus on extreme prolongations and the extent of their carry-over. While fluency is automatically generated under these extreme prolongations, the realization is that communication at this rate in routine speaking tasks is not feasible. The perceived solution is a systematic reduction in the duration of these prolongations, which attempts to approximate "normal speech." Typically, the reintroduction of speech at a normalized rate precipitates a laborious style that is undesirable to the person who stutters (PWS) and is discontinued, once departed from the comforts of the clinical setting. The inevitable typically occurs; the well-intentioned therapist instructs the PWS to focus on the techniques while speaking at a rate that is nearest normal speech, but the overlooked extreme prolongations are unlikely to ever be revisited. The foundation of this hypothesis is that the departure from fluency generators (e.g. extreme prolongations) is the cause of regression to the stuttering set point. In turn, we postulate that the continued use of extreme prolongations, as a solitary practice method, will establish and nurture different neural pathways that will create a modality of fluent speech, able to be experienced without cognitive or motoric mediation. This would therefore result in fewer occurrences of stuttering due to a phenomenon called carry-over fluency. Thus, we hypothesize that the use of extreme prolongations fosters neural pathways for fluent speech, which will result in carry-over fluency that does not require mediation by the speaker.

Abstract
BACKGROUND Many adults who stutter presenting for speech treatment experience social anxiety disorder. The presence of mental health disorders in adults who stutter has been implicated in a failure to maintain speech treatment benefits. Contemporary theories of social anxiety disorder propose that the condition is maintained by negative cognitions and information processing biases. Consistent with cognitive theories, the probe detection task has shown that social anxiety is associated with an attentional bias to avoid social information. This information processing bias is suggested to be involved in maintaining anxiety. Evidence is emerging for information processing biases being involved with stuttering. AIMS This study investigated information processing in adults who stutter using the probe detection task. Information processing biases have been implicated in anxiety maintenance in social anxiety disorder and therefore may have implications for the assessment and treatment of stuttering. It was hypothesized that stuttering participants compared with control participants would display an attentional bias to avoid attending to social information. METHODS & PROCEDURES Twenty-three adults who stutter and 23 controls completed a probe detection task in which they were presented with pairs of photographs: a face displaying an emotional expression-positive, negative or neutral-and an everyday household object. All participants were subjected to a mild social threat induction being told they would speak to a small group of people on completion of the task. OUTCOMES & RESULTS The stuttering group scored significantly higher than controls for trait anxiety, but did not differ from controls on measures of social anxiety. Non-socially anxious adults who stutter did not display an attentional bias to avoid looking at photographs of faces relative to everyday objects. Higher scores on trait anxiety were positively correlated with attention towards photographs of negative faces. CONCLUSION & IMPLICATIONS Attentional biases as assessed by the probe detection task may not be a characteristic of non-socially anxious adults who stutter. A vigilance to attend to threat information with high trait anxiety is consistent with findings of studies using the emotional Stroop task in stuttering and social anxiety disorder. Future research should investigate attentional processing in people who stutter who are socially anxious. It will also be useful for future studies to employ research paradigms that involve speaking. Continued research is warranted to explore information processing and potential biases that could be involved in the maintenance of anxiety and failure to maintain the benefits of speech treatment outcomes.

Abstract
BACKGROUND A range of interventions have been developed to treat stuttering in recent years. The effectiveness of these interventions has largely been assessed in studies focusing on the impact of specific types of therapy on patient outcomes. Relatively little is known about the factors that influence how the delivery and impact of different types of intervention may be experienced from the perspective of both people who deliver as well as those who receive interventions. AIMS To synthesize the available evidence in relation to factors that might enhance or mitigate against successful outcomes following interventions for stuttering by identifying and synthesizing relevant qualitative research that explored the experiences of people delivering and receiving interventions that aim to improve fluency. METHODS & PROCEDURES We carried out a systematic review including research that had used in-depth interviews and focus groups and conducted a substantive qualitative analysis of the data collected. Included study populations were either adults or children affected by a diagnosed stutter and/or providers of therapy for stuttering. An iterative approach was used to search for published qualitative evidence in relevant databases from 1990 to 2014. Retrieved citations were sifted for relevance and the data from articles that met the inclusion criteria were extracted. Each included paper was assessed for quality and a thematic analysis and synthesis of findings was carried out. MAIN CONTRIBUTION Synthesized qualitative evidence highlights the changing experiences for people who stutter both historically and, for individuals, over the life course. Barriers and facilitators to the implementation of interventions for stuttering are encountered at the individual, intervention, interpersonal and social levels. Interventions may be particularly pertinent at certain transition points in the life course. Attention to emotional as well as practical aspects of stuttering is valued by people receiving therapy. The client-therapist relationship and support from others are also key factors in achieving successful outcomes. CONCLUSIONS & IMPLICATIONS A synthesis of qualitative findings from published papers has added to the effectiveness data reported in an accompanying paper in understanding how stuttering impacts on people across the life course. Evidence suggests that a client-centred and individually tailored approach enhances the likelihood of successful intervention outcomes through attention to emotional, situational and practical needs.

Abstract
PURPOSE Despite the greatly increased risk of social anxiety disorder in adults who stutter, there is no clear indication of the time of onset of this disorder in childhood and adolescence. The purpose of this study was to explore this issue further using the Revised Children's Manifest Anxiety Scale (RCMAS), so that appropriate interventions can be developed prior to adulthood. This is the first time the RCMAS has been completed by children younger than 11 years. Using the same test for both school-age children and adolescents can potentially identify when anxiety starts to develop from age 6 years through to adulthood. METHODS The RCMAS was administered to 18 school-age boys, five school-age girls, 41 adolescent boys and nine adolescent girls who were seeking treatment for their stuttering. Participants also rated the severity of their own stuttering. RESULTS All mean scaled scores on the four RCMAS subscales and Total Anxiety scores were within normal limits. However, for both groups of boys, scores on the Lie Scale were significantly higher than scores on the other three subscales. CONCLUSIONS Experts suggest high scores on the RCMAS Lie Scale are indicative of participants attempting to present themselves in a positive light and so cast doubt on the veracity of their other responses on the test. One interpretation, then, is that the boys were concealing true levels of anxiety about their stuttering. The results suggest why findings of anxiety studies in children and adolescents to date are equivocal. Clinical implications are discussed. EDUCATIONAL OBJECTIVES The reader will be able to: (a) discuss why understanding when anxiety starts in people who stutter is important, (b) describe the function of the RCMAS Lie sub scale and (c) summarize the possible implications of the RCMAS findings in this study.

Abstract
PURPOSE The purpose of this study was to evaluate the incremental cost-effectiveness and cost-utility of the Lidcombe Program (LP) compared with treatment based on the Demands and Capacities Model (RESTART-DCM) for preschool children who stutter. METHOD A cost-effectiveness and cost-utility analysis were carried out alongside a Randomized Clinical Trial (the RESTART-study). In total, 199 children in 20 speech clinics participated. Outcome measures included the number needed to treat, based on the percentage of children who did not stutter at 18 months, and Health-related Quality of Life (EQ-VAS and HUI3) at 3, 6, 12 and 18 months. Health-related Quality of Life scores were used to calculate quality adjusted life years (V-QALYs for the EQ-VAS and U-QALYs for the HUI3). Direct and indirect costs were measured by cost questionnaires. Missing data were multiply imputed. Percentages of children who did not stutter in both groups were compared by a chi-square test. Between-group differences in mean QALYs and costs, as well as cost effectiveness and cost-utility ratios, were evaluated by applying bootstrapping techniques. RESULTS After 18 months, health outcomes were slightly better in the LP group, although only the difference in V-QALYs was statistical significant (0.018; 95% CI: 0.008 to 0.027) with a small effect size (Cohen's d=0.17). Mean costs for the LP group were significantly higher compared to the RESTART-DCM group (€3199 versus €3032), again with a small effect size (Cohen's d=0.14). The incremental cost-effectiveness ratio was €3360 for one additional child who did not stutter with the LP, and the estimated cost-utility ratios were €10,413 (extra cost per extra V-QALY) and €18,617 (extra cost per extra U-QALY). The results indicated a high probability that the LP is cost-effective compared to RESTART-DCM treatment given a threshold for willingness-to-pay of €20,000 per QALY. CONCLUSIONS Differences in effects and costs between the LP and RESTART-DCM treatment were small. Cost-effectiveness and cost-utility ratios were in favor of the LP. The LP is considered a good alternative to RESTART-DCM treatment in Dutch primary care.

Abstract
PURPOSE The purpose of this study was to explore the attitudes and beliefs of speech-language pathologists (SLPs) with regard to the Lidcombe Program and Demands and Capacities-based treatment and to examine how these attitudes and beliefs might have changed as a result of participating in the RESTART-study. METHOD A focus group meeting with 13 SLPs was organized. The discussion was structured using questions on therapy preference, attitudes about and explicit comparison of both treatments and treatment manuals, and learnings of trial participation. RESULTS Four main themes were identified. First, a change in attitude toward treatment choice was observed. Second, this change was related to a change in beliefs about the potential of both treatments. Third, aspects of the treatments regarded as success factors were considered. Last, learning outcomes and increased professionalism as a result of participating in the RESTART-trial were discussed. CONCLUSIONS This study showed how attitudes and beliefs of SLPs with regard to the Lidcombe Program and Demands and Capacities-based treatment evolved during a randomized trial. This work increases our understanding of the role of attitudes and beliefs in the uptake and utilization of therapies and demonstrates the importance of collecting qualitative data. Results and recommendations should prove of value in implementing the RESTART-trial results and in training SLPs.

Part 1: a systematic review of effectiveness. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2015; 50:676-718. [PMID: 26123259 PMCID: PMC4755200 DOI: 10.1111/1460-6984.12171] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2014] [Revised: 02/13/2015] [Accepted: 02/16/2015] [Indexed: 05/13/2023]
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 In order to determine whether adults who stutter (AWS) would show changes in locus of causality during stuttering treatment and approximate those of adults who do not stutter (AWNS) this preliminary study compared the locus of causality as indicated by Origin and Pawn scaling procedures from two groups of young adults who do and do not stutter. METHOD A total of 20 age- and gender-matched undergraduate and graduate students who did (n = 10) and did not (n = 10) stutter participated. The AWS took part in a three week intensive stuttering treatment provided by the American Institute for Stuttering (AIS). Along with measures of treatment outcome, writing samples were analyzed for Origin and Pawn statements that indicated the participant's locus of causality. RESULTS At the outset of treatment the AWS showed significantly greater Pawn scores than the control group of AWNS and similar occurrences of Origin statements. The AWS showed a statistically significant increase in pre- to post-treatment Origin scores and a statistically significant decrease in Pawn scores. Following treatment the AWS showed the Origin and Pawn score ratios similar to those of AWNS. CONCLUSION A pattern of increasing Origin and decreasing Pawn scores may indicate a pattern of increasing agency during successful stuttering treatment. Moreover the post-treatment Origin and Pawn score ratios of AWS, which were not significantly different from those of AWNS, may indicate a change trend toward normalization. Further research will determine whether such change patterns are predictive of long-term maintenance. EDUCATIONAL OBJECTIVES By reading this article the reader will be able to: (a) describe advantages of content analysis measure such as the Origin and Pawn Scales; (b) discuss the purposes and procedures of the Origin and Pawn Scales; (c) describe typical change pattern of Origin and Pawn scores of adults who stutter while receiving treatment; (d) discuss how successful treatment for stuttering can result in the normalization of one's locus of causality.

Abstract
PURPOSE The present study presents treatment duration and outcome data on 14 children who stutter (CWS) recently treated by the Lidcombe Program (LP). These data were then combined with data from a previous LP treatment study (Miller & Guitar, 2009) to examine predictor variables for treatment duration and outcome. The present study also provides evidence of the effectiveness of LP from researchers who are independent of the developers of the program. METHOD Fourteen preschool CWS were assessed on stuttering severity variables and participant characteristics prior to treatment, given LP treatment, and reassessed 2 years after the children achieved stable fluency. These children's data were added to the data of 15 previously treated CWS to examine predictors of treatment duration and long-term outcome. Preliminary analysis lead to the identification of two predictors that were tested in a generalized linear model. RESULTS For the new group of 14 CWS, median treatment duration was 15 clinic visits and resulted in near-zero stuttering long term for most of the children and substantial reductions in stuttering for all of the children. For the combined group of 29 children, pretreatment stuttering frequency and severity were the best predictors of treatment duration in both clinic visits and weeks. CONCLUSIONS Children with more frequent and more severe stuttering may take longer in LP treatment. Long-term outcome may best be predicted by pretreatment stuttering and sex.

Abstract
OBJECTIVE Stuttering is a common childhood disorder. There is limited high quality evidence regarding options for best treatment. The aim of the study was to compare the effectiveness of direct treatment with indirect treatment in preschool children who stutter. METHODS In this multicenter randomized controlled trial with an 18 month follow-up, preschool children who stutter who were referred for treatment were randomized to direct treatment (Lidcombe Program; n = 99) or indirect treatment (RESTART-DCM treatment; n = 100). Main inclusion criteria were age 3-6 years, ≥3% syllables stuttered (%SS), and time since onset ≥6 months. The primary outcome was the percentage of non-stuttering children at 18 months. Secondary outcomes included stuttering frequency (%SS), stuttering severity ratings by the parents and therapist, severity rating by the child, health-related quality of life, emotional and behavioral problems, and speech attitude. RESULTS Percentage of non-stuttering children for direct treatment was 76.5% (65/85) versus 71.4% (65/91) for indirect treatment (Odds Ratio (OR), 0.6; 95% CI, 0.1-2.4, p = .42). At 3 months, children treated by direct treatment showed a greater decline in %SS (significant interaction time x therapy: β = -1.89; t(282.82) = -2.807, p = .005). At 18 months, stuttering frequency was 1.2% (SD 2.1) for direct treatment and 1.5% (SD 2.1) for indirect treatment. Direct treatment had slightly better scores on most other secondary outcome measures, but no differences between treatment approaches were significant. CONCLUSIONS Direct treatment decreased stuttering more quickly during the first three months of treatment. At 18 months, however, clinical outcomes for direct and indirect treatment were comparable. These results imply that at 18 months post treatment onset, both treatments are roughly equal in treating developmental stuttering in ways that surpass expectations of natural recovery. Follow-up data are needed to confirm these findings in the longer term. TRIAL REGISTRATION isrctn.org ISRCTN24362190.

Abstract
PURPOSE Case-study methodology studying change is often used in the field of speech-language pathology, but it can be criticized for not being statistically robust. Yet with the heterogeneous nature of many communication disorders, case studies allow clinicians and researchers to closely observe and report on change. Such information is valuable and can further inform large-scale experimental designs. In this research note, a statistical analysis for case-study data is outlined that employs a modification to the Reliable Change Index (Jacobson & Truax, 1991). The relationship between reliable change and clinical significance is discussed. Example data are used to guide the reader through the use and application of this analysis. METHOD A method of analysis is detailed that is suitable for assessing change in measures with binary categorical outcomes. The analysis is illustrated using data from one individual, measured before and after treatment for stuttering. CONCLUSIONS The application of this approach to assess change in categorical, binary data has potential application in speech-language pathology. It enables clinicians and researchers to analyze results from case studies for their statistical and clinical significance. This new method addresses a gap in the research design literature, that is, the lack of analysis methods for noncontinuous data (such as counts, rates, proportions of events) that may be used in case-study designs.

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
To study the effects of clinicians' slow rate on the speech of children who stutter with and without a concomitant phonological disorder, an A-B-A-B single case design was used with six clinician-child dyads, where B = Clinician's slow speech rate model. Two boys and one girl, aged 49-54 months, stuttering with disordered phonology (S + DP), were compared to three boys aged 42-50 months, stuttering with normal phonology (S + NP). Articulation rates were measured in phones per second (pps) in clinician-child adjacent utterance pairs. The S + NP dyads showed improved fluency in the B condition through a larger effect size, higher mean baseline stutter reductions and lower percentages of non-overlapping data than did the S + DP dyads. The S + DP girl showed relatively improved fluency in the B condition. S + DP children showed no articulation rate alignment (Range: 16% decrease to a 1.2% increase), whereas S + NP children averaged a 20% pps rate reduction (Range: 19.6-25.4% decrease), aligning with their clinicians who averaged a 38% pps rate reduction from baseline. The S + DP group spoke significantly (z = -4.63; p < 0.00) slower at baseline (Mdn = 6.9 pps; SE = 0.07 pps) than S + NP children in previously published samples (Mdn = 9.8 pps; SE = 0.22 pps). Results suggest that a slow rate model alone is not effective for facilitating fluency in S + DP boys with time since onset of about 2 years.

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
PURPOSE Virtual reality environments (VREs) are computer-generated, 3-dimensional worlds that allow users to experience situations similar to those encountered in the real world. The purpose of this study was to investigate VREs for potential use in assessing and treating persons who stutter (PWS) by determining the extent to which PWS's affective, behavioral, and cognitive measures in a VRE correlate with those same measures in a similar live environment. METHOD Ten PWS delivered speeches-first to a live audience and, on another day, to 2 virtual audiences (neutral and challenging audiences). Participants completed standard tests of communication apprehension and confidence prior to each condition, and frequency of stuttering was measured during each speech. RESULTS Correlational analyses revealed significant, positive correlations between virtual and live conditions for affective and cognitive measures as well as for frequency of stuttering. CONCLUSIONS These findings suggest that virtual public speaking environments engender affective, behavioral, and cognitive reactions in PWS that correspond to those experienced in the real world. Therefore, the authentic, safe, and controlled environments provided by VREs may be useful for stuttering assessment and treatment.

Abstract
PURPOSE This study aims to determine whether the communication and language skills of children who have a history of stuttering are different from children who do not have a history of stuttering at ages 2-5 years. METHOD This study utilizes data from the Early Language in Victoria Study (ELVS), a longitudinal study with a community sample of 1910 children recruited in Melbourne, Australia, as well as a concurrent study examining the onset and progression of stuttering. Participants with a history of stuttering (n = 181) and a control group without a history of stuttering (n = 1438) were identified according to the established protocol of these two existing studies. RESULT The stuttering group scored higher than the non-stuttering group on all of the communication and language outcomes measured. The group differences were statistically significant on four of the seven measures and these findings were maintained when potentially confounding factors were controlled for. CONCLUSION Importantly, the children with a history of stuttering, as a group, and the control group without a history of stuttering demonstrated developmentally-appropriate early communication and language skills.

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
BACKGROUND Negative attitudes toward stuttering and people who stutter (PWS) are found in various groups of people in many regions. However the results of previous studies examining the influence of fluency coursework and clinical certification on the attitudes of speech-language pathologists (SLPs) toward PWS are equivocal. Furthermore, there have been few empirical studies on the attitudes of Korean SLPs toward stuttering. AIMS To determine whether the attitudes of Korean SLPs and speech-language pathology students toward stuttering would be different according to the status of clinical certification, stuttering coursework completion and clinical practicum in stuttering. METHODS & PROCEDURES Survey data from 37 certified Korean SLPs and 70 undergraduate students majoring in speech-language pathology were analysed. All the participants completed the modified Clinician Attitudes Toward Stuttering (CATS) Inventory. OUTCOMES & RESULTS Results showed that the diagnosogenic view was still accepted by many participants. Significant differences were found in seven out of 46 CATS Inventory items according to the certification status. In addition significant differences were also found in three items and one item according to stuttering coursework completion and clinical practicum experience in stuttering, respectively. CONCLUSIONS & IMPLICATIONS Clinical and educational experience appears to have mixed influences on SLPs' and students' attitudes toward stuttering. While SLPs and students may demonstrate more appropriate understanding and knowledge in certain areas of stuttering, they may feel difficulty in their clinical experience, possibly resulting in low self-efficacy.

Abstract
PURPOSE Those with anxiety use safety behaviors when attempting to prevent negative outcomes. There is evidence that these behaviors contribute to the persistence of anxiety disorders. Safety behaviors have been prominent in the cognitive behavior therapy literature during the last decade, particularly with social phobia management. However, nothing is known of safety behavior use by those who stutter. This is surprising given the high prevalence of social phobia in the stuttering population who seek clinical help. METHOD Clinical psychologists and speech-language pathologists (SLPs) created a list of safety behaviors that might be used by adults during treatment for stuttering. Participants were 160 SLPs who were asked whether they advised adults who stutter to use any of these safety behaviors. RESULTS SLPs commonly recommend safety behaviors during stuttering management. Factor structures were found for the following 5 safety behavior categories: (a) general safety behaviors, (b) practice and rehearsal, (c) general avoidance, (d) choosing safe and easy people, and (e) control-related safety behaviors. CONCLUSIONS There is a need to determine the frequency with which adults who receive stuttering treatment follow these clinician recommendations. In addition, there is a need to experimentally determine whether following such recommendations prevents fear extinction at long-term follow-up.

Abstract
PURPOSE The Lidcombe Program is an operant treatment for early stuttering shown with meta-analysis to have a favorable odds ratio. However, many clients are unable to access the treatment because of distance and lifestyle factors. In this Phase I trial, we explored the potential efficacy, practicality, and viability of an Internet webcam Lidcombe Program service delivery model. METHOD Participants were 3 preschool children who stuttered and their parents, all of whom received assessment and treatment using webcam in their homes with no clinic attendance. RESULTS At 6 months post-Stage 1 completion, all children were stuttering below 1.0% syllables stuttered. The webcam intervention was acceptable to the parents and appeared to be practical and viable, with only occasional audiovisual problems. At present, there is no reason to doubt that a webcam-delivered Lidcombe Program will be shown with clinical trials to have comparable efficacy with the clinic version. CONCLUSION Webcam-delivered Lidcombe Program intervention is potentially efficacious, is practical and viable, and requires further exploration with comparative clinical trials and a qualitative study of parent and caregiver experiences.

Abstract
PURPOSE The purpose of this study was to evaluate anxiety and psychological functioning among adolescents seeking speech therapy for stuttering using a structured, diagnostic interview and psychological questionnaires. This study also sought to determine whether any differences in psychological status were evident between younger and older adolescents. METHOD Participants were 37 stuttering adolescents seeking stuttering treatment. We administered the Computerized Voice Version of the Diagnostic Interview Schedule for Children, and five psychometric tests. Participants were classified into younger (12-14 years; n=20) and older adolescents (15-17 years; n=17). RESULTS Thirty-eight percent of participants attained at least one diagnosis of a mental disorder, according to the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV; APA, 2000), with the majority of these diagnoses involving anxiety. This figure is double current estimates for general adolescent populations, and is consistent with our finding of moderate and moderate-severe quality of life impairment. Although many of the scores on psychological measures fell within the normal range, older adolescents (15-17 years) reported significantly higher anxiety, depression, reactions to stuttering, and emotional/behavioral problems, than younger adolescents (12-14 years). There was scant evidence that self-reported stuttering severity is correlated with mental health issues. There are good reasons to believe these results are conservative because many participants gave socially desirable responses about their mental health status. DISCUSSION These results reveal a need for large-scale, statistically powerful assessments of anxiety and other mental disorders among stuttering adolescents with reference to control populations. EDUCATIONAL OBJECTIVES The reader will be able to: (a) explain the clinical importance of assessing for mental health with stuttering adolescents, (b) state the superior method for adolescent mental health assessment and (c) state a major issue with determining the genuineness of stuttering adolescent responses to psychological assessment.
