A professional perspective on EBP in stuttering: How far have we come in 20 years?

This article reviews a critique by Bernstein Ratner (2005) to identify progress made in applying EBP to stuttering intervention and areas in which less progress has been observed. Among indices of progress are plentiful basic science and therapy outcomes reports, broader views of effectiveness, and increased representation of people who stutter in program development and evaluation. Among concerns we discuss are: (1) continued disconnects between basic science to understand the nature of stuttering and the therapies we employ with our clients; (2) a need for better understanding of causal mechanisms and mediators of change in stuttering interventions; and (3) specific challenges that make it difficult to know if therapies for early stuttering work significantly better than spontaneous recovery. We also discuss the (4) merits of broadening goals for preschool-aged children and their families; and (5) discuss potential negative ramifications of weakly supported interventions and recommendations for children whose stuttering persists past preschool. We conclude with a section on (6) important questions and populations that we believe remain under- investigated.
