The authors report treatment duration and outcome data on 14 children who stutter (CWS) recently treated by the Lidcombe Program (LP). These data were then combined with data from a previous LP treatment study (Miller and Guitar, 2009) to examine predictor variables for treatment duration and outcome. The study provides evidence of the effectiveness of LP from researchers who are independent of the developers of the program. The authors concluded that children with more frequent and more severe stuttering may take longer in LP treatment. Long-term outcome may be best be predicted by pre-treatment stuttering and sex.
