Purpose: The Lidcombe Program is an efficacious and effective intervention for early stuttering. The treatment is based on parent verbal response contingent stimulation procedures, which are assumed to be responsible for treatment effect. The present trial tested this assumption. Method: The design was a parallel, open plan, noninferiority…

Guidelines for documenting treatment efficacy for young children who stutter are suggested and illustrated. Measures in four realms are delineated: (1) conditions of documentation, (2) dependent variables, (3) establishment of treatment integrity, and (4) verification of the relationship between treatment and outcome.

A parent-conducted program of verbal response-contingent stimulation was effectively used to reduce stuttering to near zero levels in 12 children (younger than age 5). Treatments were completed in a median of 10.5 1-hour clinic sessions and 84.5 days. (Author/DB)
