Background: The Rotterdam Evaluation Study of Stuttering Therapy randomized trial (RESTART) was seminal, comparing the Lidcombe Program with RESTART Demands and Capacities Model-based treatment (RESTART-DCM) for pre-school age children who stutter. Aims: To critique the methods of the RESTART trial to develop guidelines for its systematic…

Purpose: The purpose of this study was to ascertain if there is an association between stuttering severity and behaviors and the expression of temperament characteristics, including precursors of anxiety. Method: We studied temperament characteristics of a prospectively recruited community cohort of children who stutter (N = 173) at ages 3, 4, and…

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 purpose of this study was to ascertain whether and when temperament differences, including precursors of anxiety, emerge before onset and during stuttering development. Method: The authors prospectively studied temperament characteristics of a community cohort of children who stutter (N = 183) and children in the control group (N =…

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: This study adds to the Lidcombe Program evidence base by comparing individual and group treatment of preschoolers who stutter. Method: A randomized controlled trial of 54 preschoolers was designed to establish whether group delivery outcomes were not inferior to the individual model. The group arm used a rolling group model, in which a…

Speech-language pathologists (SLPs) are advised to consider the distress of preschoolers and parents along with the social consequences of the child's stuttering when deciding whether to begin or delay treatment. Seventy-seven parents completed a survey that yielded quantitative and qualitative data that reflected their perceptions of the impact…

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, with…

Purpose: This study investigated peer responses to preschoolers' stuttering in preschool and sought to determine whether specific characteristics of participants' stuttering patterns elicited negative peer responses. Method: Four outdoor free-play sessions of 4 preschoolers age 3-4 years who stutter were videotaped. Stutters were identified on…

Purpose: To determine whether measures of stuttering frequency and measures of overall stuttering severity in preschoolers differ when made from audio-only recordings compared with audiovisual recordings. Method: Four blinded speech-language pathologists who had extensive experience with preschoolers who stutter measured stuttering frequency and…

Background: In the Lidcombe Program of Early Stuttering Intervention, parents present verbal contingencies for stutter-free and stuttered speech in everyday situations. A previous randomized controlled trial of the programme with preschool-age children from 2005, conducted in two public speech clinics in New Zealand, showed that the odds of…

Purpose: In order to produce a compact and readable overview of clinical issues for clinicians, the authors developed a "1,000-bites" format in which they discuss a topic initiated by one of the authors. Method: The format is designed to give the reader the feeling of contemporaneous observation of a conversation between 2 authors. To that end,…

Knowledge of variables that predict treatment time is of benefit in deciding when to start treatment for early stuttering. To date, the only variable clearly related to treatment time with the Lidcombe Program is pre-treatment stuttering frequency. Previous studies have shown that children whose stuttering is more severe take longer to complete…

Background: Data have accumulated to show that the Lidcombe Program of early stuttering intervention is a safe treatment with positive outcomes for preschoolers who stutter, and a randomized controlled trial is under way at the time of writing. Program components have not been investigated experimentally so the functionality of each component is…

Purpose: The aims of this study were to evaluate the efficacy of telehealth delivery of the Lidcombe Program of Early Stuttering Intervention, compared with a control group, and to determine the number of children who could be regarded as "responders." Method: A speech-language pathologist provided telehealth delivery of the Lidcombe…
