Improved fluency after stuttering therapy is usually measured by the percentage of stuttered syllables. However, outcome studies rarely evaluate the use of trained speech patterns that speakers use to manage stuttering. This study investigated whether the modified time interval analysis can distinguish between trained speech patterns, fluent…

Purpose: This study investigated the relationship between self-reported stuttering severity ratings and educational attainment. Method: Participants were 147 adults seeking treatment for stuttering. At pretreatment assessment, each participant reported the highest educational level they had attained and rated their typical and worst stuttering…

Purpose: Live oral or recorded video presentations on stuttering were delivered to high school students in order to determine the extent to which their attitudes toward stuttering could be improved. Methods: A classroom teacher administered the "Public Opinion Survey of Human Attributes-Stuttering" ("POSHA-S") to two health classes before and…

Background: Altered auditory feedback can facilitate speech fluency in adults who stutter. However, other findings suggest that adults who stutter show anomalies in "audiovocal integration", such as longer phonation reaction times to auditory stimuli and less effective pitch tracking. Aims: To study audiovocal integration in adults who stutter…

Background: Narrative therapy (White & Epston, 1990) was developed as an approach to counselling, as a response to the power relations that influence people's lives. Its use with people who stutter has been documented. A basic tenet of narrative therapy is that the dominant problem-saturated narrative is challenged by externalizing the problem, in…

Purpose: To investigate the impact on percentage of syllables stuttered of various durations of delayed auditory feedback (DAF), levels of frequency-altered feedback (FAF), and masking auditory feedback (MAF) during conversational speech. Method: Eleven adults who stuttered produced 10-min conversational speech samples during a control condition…

Purpose: Chronic disorder can impose a significant negative mental health burden. This research was conducted to explore factors that may protect people from the adversity of chronic stuttering. Method: The study employed a population group cohort design. Participants included 200 adults who have stuttered since childhood, and the sample was…

Purpose: A Turkish translation of the "Public Opinion Survey of Human Attributes-Stuttering" ("POSHA-S") was used to compare probability versus convenience sampling to measure public attitudes toward stuttering. Method: A convenience sample of adults in Eskisehir, Turkey was compared with two replicates of a school-based,…

Purpose: The purpose of this study was to gain a deeper understanding of client perceptions of an intensive stuttering therapy program that utilizes a multi-faceted approach to therapy. The study also proposed to gain a deeper understanding about the process involved in long-term maintenance of meaningful changes made in therapy. Methods: The…

Parental input has been described as influential in early childhood stuttering yet the exact nature of this influence remains equivocal. The present study aimed to examine whether quantitative measures of parenting styles, parent and peer attachment patterns, and parent- and self-reported child behaviour could differentiate between school-aged…

The SpeechEasy has been found to be an effective device for reduction of stuttering frequency for many people who stutter (PWS); published studies typically have compared stuttering reduction at initial fitting of the device to results achieved up to one year later. This study examines long-term effectiveness by examining whether effects of the…

Purpose: Previous investigations of persons who stutter have demonstrated changes in vocalization variables during fluency-inducing conditions (FICs). A series of studies has also shown that a reduction in short intervals of phonation, those from 30 to 200 ms, is associated with decreased stuttering. The purpose of this study, therefore, was to…

The etiology of persistent stuttering is unknown, but stuttering has been attributed to multiple potential factors, including difficulty in processing language-related information, but findings remain inconclusive regarding any "specific" linguistic deficit potentially causing stuttering. One particular challenge in drawing conclusions is the…

Riley's Stuttering Severity Instrument (SSI) is widely used. The manuals allow SSI assessments to be made in different ways (e.g. from digital recordings or whilst listening to speech live). Digital recordings allow segments to be selected and listened to, whereas the entire recording has to be judged when listened to live. Comparison was made…

The phonological complexity of dysfluencies in those who clutter and/or stutter may help us better understand phonetic factors in these two types of fluency disorders. In this preliminary investigation, cases were three 14-year-old males, diagnosed as a Stutterer, a Clutterer, and a Stutterer-Clutterer. Spontaneous speech samples were transcribed,…
