Purpose: This prologue serves to introduce a research forum composed of studies that address the topic of stuttering in school-age children and adolescents. Researchers are encouraged to continue to build the knowledge base that sustains evidence-based practice in this area. Method: The nature of stuttering as it evolves from early childhood into…

There is a pressing need in Iran for the translation of widely used speech-language assessment tools into Persian. This study reports the interjudge and intrajudge reliability of a Persian translation of the Stuttering Severity Instrument-3 (SSI-3) (Riley, 1994). There was greater than 80% interjudge and intrajudge agreement on scale scores for…

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…

This study investigated changes in the speech patterns of young adult male subjects when stuttering was modified by deliberately prolonging speech. Three subjects showed clinically significant stuttering reductions when using prolonged speech to reduce their stuttering. Resulting speech was perceptually stutter free. Acoustic and…

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…

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.)…
