This study examined intrajudge and interjudge agreement for the Lidcombe Behavioral Data Language (LBDL), a behaviorally based stuttering taxonomy. Ten experienced speech language pathologists and 10 undergraduates applied the LBDL to stuttered speech on two occasions. Intrajudge agreement was high for both groups, but only the experienced judges…

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…

This paper examines a prolonged speech treatment model for stuttering, the Camperdown Program. Sixteen participants showed minimal or no stuttering in everyday speaking situations for up to 12 months after entering the program's maintenance phase, with speech rates in the normal range. Results were achieved in a mean of 20 hours of clinic…

A time-out from speaking contingency was evaluated in the treatment of stuttering in three school-age children. A red light time-out signal appeared for five seconds when the child stuttered. Two of the children responded to time-out with clear reductions in stuttering. Listeners did not detect any differences between the perceptually stutter-free…

Background: The paper reports on a laboratory investigation of the effects of self-modelling on stuttering rate in adolescents and adults. Self-modelling refers to a therapeutic or training method, usually involving videotape, that uses exposure to oneself performing selected error-free behaviours as the conduit for promoting behaviour change.…

A study investigated whether age, gender, period from onset to treatment, and stuttering severity related to the required treatment time of 250 preschoolers who completed the Lidcombe Program. Data indicate that, for a short period after stuttering onset, a short delay in treatment did not appear to increase treatment time. (Contains references.)…
