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…

Background: Information is available about what predicts Lidcombe Program treatment time, but nothing is known about what predicts treatment prognosis. Aims: To investigate the predictors of treatment dropout and treatment outcome for children who were treated for early stuttering with the Lidcombe Program (N = 277). Methods & Procedures: A…

Purpose: The Lidcombe Program is an efficacious and effective intervention for early stuttering. The treatment is based on parent verbal response contingent stimulation procedures, which are assumed to be responsible for treatment effect. The present trial tested this assumption. Method: The design was a parallel, open plan, noninferiority…

Purpose: This report investigates whether parent-reported stuttering severity ratings (SRs) provide similar estimates of effect size as percentage of syllables stuttered (%SS) for randomized trials of early stuttering treatment with preschool children. Method: Data sets from 3 randomized controlled trials of an early stuttering intervention were…

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…

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…

Purpose: This clinical trial determined the outcomes of a simple syllable-timed speech (STS) treatment for school-age children who stutter. Method: Participants were 10 children, ages 6-11 years, who stutter. Treatment involved training the children and their parents to use STS at near normal speech rates. The technique was practiced in the clinic…

Purpose: This Phase I clinical trial explored the viability of webcam Internet delivery of the Camperdown Program for adolescents who stutter. Method and Procedure: Participants were 3 adolescents ages 13, 15, and 16 years, with moderate-severe stuttering. Each was treated with the Camperdown Program delivered by webcam with no clinic attendance.…

Background: Speech restructuring is an efficacious method for the alleviation of stuttered speech. However, post-treatment relapse is common. Aims: To investigate whether the use of video self-modelling using restructured stutter-free speech reduces stuttering in adults who had learnt a speech-restructuring technique and subsequently relapsed.…

Background: Persistent calls for school-based education about stuttering necessitate a better understanding of peer attitudes toward children who stutter and a means to measure outcomes of such educational interventions. Langevin and Hagler in 2004 developed the Peer Attitudes Toward Children who Stutter scale (PATCS) to address these needs and…

Four stutterers, aged 3-5, received treatment based on parent-administered, operant verbal stimulation. Data show that the intervention, coupled with a programed maintenance schedule, reduced stuttering and accompanied increases in syllable output. Findings suggest that cases of early stuttering might be managed effectively by parents, with…

Background: The benefits of treating stuttering close to onset have become obvious in recent years, and the Lidcombe Program has emerged as an effective and safe treatment method for children in their preschool years. The benefits of implementing the programme with young children, however, need to be weighed against the knowledge that many…
