Purpose: This study investigated the complexity of stuttering behavior. It described and classified the complexity of stuttering behavior in relation to age, behavioral treatment outcomes, stuttering severity, anxiety-related mental health, impact of stuttering, and gender. Method: For this study, a taxonomy was developed--LBDL-C7--which was based on the Lidcombe Behavioral Data Language of stuttering. It was used by five experienced judges to analyze the complexity of stuttering behavior for 84 adults and adolescents before and after speech restructuring treatment. Data were 3,100 stuttering moments, which were analyzed with nominal logistic regression. Results: The complexity of stuttering behavior appears not to change as a result of treatment, but it does appear to change with advancing age. Complexity of stuttering behavior was found to be independently associated with clinician stuttering severity scores but not with percentage of syllables stuttered or self-reported stuttering severity. Complexity of stuttering behavior was not associated with gender, anxiety, or impact of stuttering. Conclusion: Clinical and research applications of these findings are discussed.

Purpose: In this study, the authors investigated the efficacy of video self-modeling (VSM) following speech restructuring treatment to improve the maintenance of treatment effects. Method: The design was an open-plan, parallel-group, randomized controlled trial. Participants were 89 adults and adolescents who undertook intensive speech restructuring treatment. Post treatment, participants were randomly assigned to 2 trial arms: standard maintenance and standard maintenance plus VSM. Participants in the latter arm viewed stutter-free videos of themselves each day for 1 month. Results: The addition of VSM did not improve speech outcomes, as measured by percent syllables stuttered, at either 1 or 6 months postrandomization. However, at the latter assessment, self-rating of worst stuttering severity by the VSM group was 10% better than that of the control group, and satisfaction with speech fluency was 20% better. Quality of life was also better for the VSM group, which was mildly to moderately impaired compared with moderate impairment in the control group. Conclusions: VSM intervention after treatment was associated with improvements in self-reported outcomes. The clinical implications of this finding are discussed. [ABSTRACT FROM AUTHOR]

Considerable research has been directed at the outcomes of prolonged-speech (PS) treatment for the control of chronic stuttering, but little research to date has focused on the PS treatment process. This report examines a Stage 2 clinical trial of a reconceptualized PS treatment model known as the Camperdown Program. This program requires fewer clinician hours than traditional programs and has no formal transfer phase. Additionally, it incorporates the following treatment process innovations, which replace treatment process components that are intuitively and empirically problematic: (a) PS is taught without incorporating target behaviors in clinician instruction, (b) participants learn to control stuttering without programmed instruction, and (c) the treatment process does not involve clinician identification of stuttering moments. Thirty participants were initially enrolled in the trial. Final outcome data are presented for the 16 participants who completed all trial requirements, including 12 months posttreatment data collection. These 16 participants showed minimal or no stuttering in everyday speaking situations for up to 12 months after entering the maintenance program, with speech rates in the normal range. Speech naturalness and social validation data were also favorable. Although self-report data generally confirmed the speech data, the results were not as positive. The present outcomes were achieved in a mean of 20 hours of clinic attendance per participant, which is much fewer than the hours required by treatment programs reported recently that run intensively over 2-3 weeks. The promise of this Stage 2 clinical trial has led the authors to initiate a Stage 3 randomized controlled trial of the Camperdown Program. [ABSTRACT FROM AUTHOR]

This article reports the development of a tool for measuring how comfortable a person feels when communicating with someone who has undergone treatment for stuttering. The person rates the speaker on a 9-point Listener Comfort Scale (9 = extremely comfortable, 1 = extremely uncomfortable). In a preliminary investigation of the reliability and validity of the scale, 15 unsophisticated listeners rated video recordings of 10 adults before and after a prolonged-speech treatment for stuttering and of 10 matched controls. The results were compared with those of another 15 listeners who rated the same recordings with the widely used 9-point Speech Naturalness Scale (R. R. Martin, S. K. Haroldson, & K. A. Triden, 1984). Results showed that reliability of the Speech Naturalness Scale was superior to the Listener Comfort Scale, although users of both scales were able to distinguish between pretreatment speech, posttreatment speech, and the speech of controls. The results suggest that the Listener Comfort Scale captures information that is somewhat different than the information captured by the Speech Naturalness Scale. The authors concluded that the concept of listener comfort is a potentially useful additional way of investigating the social validity of behavioral treatments for stuttering. [ABSTRACT FROM AUTHOR]
