Avoidance of eye gaze by adults who stutter.

PURPOSE Adults who stutter are at significant risk of developing social phobia. Cognitive theorists argue that a critical factor maintaining social anxiety is avoidance of social information. This avoidance may impair access to positive feedback from social encounters that could disconfirm fears and negative beliefs. Adults who stutter are known to engage in avoidance behaviours, and may neglect positive social information. This study investigated the gaze behaviour of adults who stutter whilst giving a speech. METHOD 16 adults who stutter and 16 matched controls delivered a 3-min speech to a television display of a pre-recorded lecture theatre audience. Participants were told the audience was watching them live from another room. Audience members were trained to display positive, negative and neutral expressions. Participant eye movement was recorded with an eye-tracker. RESULTS There was a significant difference between the stuttering and control participants for fixation duration and fixation count towards an audience display. In particular, the stuttering participants, compared to controls, looked for shorter time at positive audience members than at negative and neutral audience members and the background. CONCLUSIONS Adults who stutter may neglect positive social cues within social situations that could serve to disconfirm negative beliefs and fears. EDUCATIONAL OBJECTIVES The reader will be able to: (a) describe the nature of anxiety experienced by adults who stutter; (b) identify the most common anxiety condition among adults who stutter; (c) understand how information processing biases and the use of safety behaviours contribute to the maintenance of social anxiety; (d) describe how avoiding social information may contribute to the maintenance of social anxiety in people who stutter; and (e) describe the clinical implications of avoidance of social information in people who stutter.

A standalone Internet cognitive behavior therapy treatment for social anxiety in adults who stutter: CBTpsych

PURPOSE Social anxiety is common for those who stutter and efficacious cognitive behavior therapy (CBT) for them appears viable. However, there are difficulties with provision of CBT services for anxiety among those who stutter. Standalone Internet CBT treatment is a potential solution to those problems. CBTpsych is a fully automated, online social anxiety intervention for those who stutter. This report is a Phase I trial of CBTpsych. METHOD Fourteen participants were allowed 5 months to complete seven sections of CBTpsych. Pre-treatment and post-treatment assessments tested for social anxiety, common unhelpful thoughts related to stuttering, quality of life and stuttering frequency. RESULTS Significant post-treatment improvements in social anxiety, unhelpful thoughts, and quality of life were reported. Five of seven participants diagnosed with social anxiety lost those diagnoses at post-treatment. The two participants who did not lose social anxiety diagnoses did not complete all the CBTpsych modules. CBTpsych did not improve stuttering frequency. Eleven of the fourteen participants who began treatment completed Section 4 or more of the CBTpsych intervention. CONCLUSIONS CBTpsych provides a potential means to provide CBT treatment for social anxiety associated with stuttering, to any client without cost, regardless of location. Further clinical trials are warranted. EDUCATIONAL OBJECTIVES At the end of this activity the reader will be able to: (a) describe that social anxiety is common in those who stutter; (b) discuss the origin of social anxiety and the associated link with bullying; (c) summarize the problems in provision of effective evidence based cognitive behavior therapy for adults who stutter; (d) describe a scalable computerized treatment designed to tackle the service provision gap; (e) describe the unhelpful thoughts associated with stuttering that this fully automated computer program was able to tackle; (f) list the positive outcomes for individuals who stuttered that participated in this trial such as the reduction of social anxiety symptoms and improvement in the quality of life for individuals who stuttered and participated in this trial.

Webcam Delivery of the Lidcombe Program for Early Stuttering: A Phase I Clinical Trial

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.

Children and adolescents who stutter: Further investigation of anxiety.

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 Childrens 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.

International Phase II clinical trial of CBTPsych: A standalone Internet social anxiety treatment for adults who stutter

PURPOSE CBTPsych is an individualized, fully automated, standalone Internet treatment program that requires no clinical contact or support. It is designed specifically for those who stutter. Two preliminary trials demonstrated that it may be efficacious for treating the social anxiety commonly associated with stuttering. However, both trials involved pre- and post-treatment assessment at a speech clinic. This contact may have increased compliance, commitment and adherence with the program. The present study sought to establish the effectiveness of CBTPsych in a large international trial with no contact of any kind from researchers or clinicians. METHOD Participants were 267 adults with a reported history of stuttering who were given a maximum of 5 months access to CBTPsych. Pre- and post-treatment functioning was assessed within the online program with a range of psychometric measures. RESULTS Forty-nine participants (18.4%) completed all seven modules of CBTPsych and completed the post-treatment online assessments. That compliance rate was far superior to similar community trials of self-directed Internet mental health programs. Completion of the program was associated with large, statistically and clinically significant reductions for all measures. The reductions were similar to those obtained in earlier trials of CBTPsych, and those obtained in trials of in-clinic CBT with an expert clinician. CONCLUSIONS CBTPsych is a promising individualized treatment for social anxiety for a proportion of adults who stutter, which requires no health care costs in terms of clinician contact or support. EDUCATIONAL OBJECTIVES The reader will be able to: (a) discuss the reasons for investigating CBTPsych without any clinical contact; (b) describe the main components of the CBTPsych treatment; (c) summarize the results of this clinical trial; (d) describe how the results might affect clinical practice, if at all.

Absolute and relative reliability of percentage of syllables stuttered and severity rating scales.

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.

Standalone Internet speech restructuring treatment for adults who stutter: A phase I study

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.

Phase II trial of a syllable-timed speech treatment for school-age children who stutter

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 childs stuttered and stutter-free speech and to praise their childs 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.

Observer perspective imagery with stuttering

Abstract Purpose: Adults who stutter are at risk of developing a range of psychological conditions. Social anxiety disorder is the most common anxiety disorder associated with stuttering. Observer perspective imagery is one cognitive process involved in the maintenance of some anxiety disorders. This involves viewing images as if looking at the self from the perspective of another. In contrast, the field perspective involves looking out from the self at the surrounding environment. The purpose of this study was to assess the presence of observer perspective imagery with stuttering. Method: The authors administered the Hackmann, Surawy and Clark (1998) semi-structured interview to 30 adults who stutter and 30 controls. Group images and impressions were compared for frequency, perspective recalled and emotional valence. Result: The stuttering group was significantly more likely than controls to recall images and impressions from an observer rather than a field perspective for anxious situations. Conclusion: It is possible the present results could reflect the same attentional processing bias that occurs with anxiety disorders in the non-stuttering population. These preliminary results provide an explanation for the persistence of conditions such as social anxiety disorder with stuttering. Clinical implications are discussed.

The Satisfaction with Communication in Everyday Speaking Situations (SCESS) scale: An overarching outcome measure of treatment effect

PURPOSE The Consolidated Standards of Reporting Trials (CONSORT) statement strongly suggests one primary outcome for clinical trials, yet the outcomes of stuttering treatments span numerous behavioral and psychosocial domains. That presents a roadblock to eventual meta-analysis of clinical trials for adults who stutter. METHOD We propose a simple and convenient outcome measure for clinical trials of stuttering treatment for adults that spans whatever behavioral and psychosocial factors might impel clients to seek treatment: a nine-point scale of Satisfaction with Communication in Everyday Speaking Situations (SCESS). The scale consists of one question which is simple, brief, easy to administer, cost-free, and translatable into many languages. The present report develops the SCESS scale by determining its reliability, content validity, and construct validity. RESULTS Reliability, content validity, and construct validity of the SCESS were confirmed with statistically significant and substantive correlations with speech-related and anxiety-related measures. However, the SCESS did not correlate well with percentage syllables stuttered. Three behavioral and psychosocial measures had the highest correlation with the SCESS: total Overall Assessment of the Speakers Experience of Stuttering, self-reported stuttering severity, and Unhelpful Thoughts and Beliefs about Stuttering. CONCLUSION The SCESS measure has potential to be applied as an overarching clinical trial outcome measure of stuttering treatment effect. This study provides some preliminary evidence for including it as a primary or secondary outcome in clinical trials of adult stuttering treatments. However, further studies are needed to establish the SCESS responsiveness to different stuttering treatments.
