Purpose: This study was designed to answer three questions: (a) Does percentage of syllables stuttered (%SS) differ between standard and challenge phone calls; (b) Does anxiety differ between standard and challenge phone calls; and (c) Is there a relationship between %SS and anxiety during standard and challenge phone calls? Method: Participants…

Purpose: The purpose of this review article is to provide an overview of the current evidence base for the behavioral management of stuttering and associated social anxiety. Method: We overview recent research about stuttering and social anxiety in the context of contemporary cognitive models of social anxiety disorder. That emerging evidence for…

Background: Early intervention is essential healthcare for stuttering, and the translation of research findings to community settings is a potential roadblock to it. Aims: This study was designed to replicate and extend the Lidcombe Program community translation findings of O'Brian et al. (2013) but with larger participant numbers, incorporating…

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: Those who are socially anxious may use safety behaviors during feared social interactions to prevent negative outcomes. Safety behaviors are associated with anxiety maintenance and poorer treatment outcomes because they prevent fear extinction. Social anxiety disorder is often comorbid with stuttering. Speech pathologists reported in a…

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…

Background: Many adults who stutter presenting for speech treatment experience social anxiety disorder. The presence of mental health disorders in adults who stutter has been implicated in a failure to maintain speech treatment benefits. Contemporary theories of social anxiety disorder propose that the condition is maintained by negative…
