UNLABELLED Stuttering is frequently associated with negative consequences which typically begin in early childhood. Despite this, no previous studies have investigated the presence of personality disorders among adults who stutter. Therefore, the aims of the present study were to screen for personality disorders among adults who stutter, and to compare(More)
UNLABELLED Previous research has not explored the Five Factor Model of personality among adults who stutter. Therefore, the present study investigated the five personality domains of Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness, as measured by the NEO Five Factor Inventory (NEO-FFI), in a sample of 93 adults seeking speech(More)
PURPOSE This study reports the development and clinical trial of a new treatment program for persistent developmental stuttering in adolescents and adults. The treatment is based on the operant procedure of self-imposed time-out. This involves the person stopping speaking for a short period after each stutter. METHOD Twenty-two participants completed(More)
The present study explored the prevalence of anxiety disorders among adults seeking speech therapy for stuttering. Employing a matched case-control design, participants included 92 adults seeking treatment for stuttering, and 920 age- and gender-matched controls from the Australian National Survey of Mental Health and Well-being. A conditional logistic(More)
This report presents a Phase II clinical trial of a syllable-timed speech treatment for early stuttering known as The Westmead Program. Of 17 children recruited, eight children aged between 3-4.5 years (mean 3 years 8 months) completed the treatment. The primary outcome measure was percentage syllables stuttered (%SS) measured from independent, blinded(More)
This study investigated the comparative reliability of 2 stuttering measurement tools when used by experienced judges: percentage of syllables stuttered (%SS) and a 9-point severity scale (SEV). The study also investigated the degree to which scores on 1 tool predict scores on the other and the distributions of stuttering when measured by these tools.(More)
Scaling is a convenient and equipment-free means for speech-language pathologists (SLPs) and clients to evaluate stuttering severity in everyday situations. This study investigated the extent to which the severity ratings of 10 adult stuttering speakers, made immediately after speaking and again from recordings 6 months later, agreed with ratings made by an(More)
PURPOSE The relationship between anxiety and stuttering has been widely studied. However, a review conducted more than 10 years ago (Menzies, Onslow, & Packman, 1999) identified 5 methodological issues thought to preclude consistent research findings regarding the nature of this relationship. The purpose of the present review was to determine whether(More)
UNLABELLED This report presents the results of an experimental investigation of the effects of a syllable-timed speech treatment on three stuttering preschool children. Syllable-timed speech involves speaking with minimal differentiation in linguistic stress across syllables. Three children were studied in a multiple baseline across participants design,(More)
PURPOSE Stuttering varies between and within speaking situations. In this study, the authors used statistical process control charts with 10 case studies to investigate variability of stuttering frequency. METHOD Participants were 10 adults who stutter. The authors counted the percentage of syllables stuttered (%SS) for segments of their speech during(More)
