Experimental treatment of early stuttering: a preliminary study

This pilot study compared two treatments for stuttering in preschool-age children. Thirty children were randomly assigned to either a Lidcombe Program (LP) treatment or a Demands and Capacities Model (DCM) treatment. Stuttering frequencies and severity ratings were obtained immediately before and after treatment (12 weeks). The stuttering frequencies and severity ratings significantly decreased for both treatment groups. No differences between groups were found. Parents of children in both groups were cooperative in many respects, and there were no differences between them on scales that measured their satisfaction with the two treatments. The findings suggest that randomized controlled trials of LP versus DCM treatments are feasible, and they underline the need for experimental analyses of the two treatments. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) describe the principles and methods of Lidcombe treatment for early stuttering; (2) delineate principles and methods of Demands and Capacities Model treatment; and (3) summarize results of an investigation that compared these programs' relative effects in a pilot study.
