Abstract

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 total of 32 variables were used as predictors in regression analyses of short- and medium-term Lidcombe Program outcome, and of treatment dropout.

Outcomes & Results

Regression analyses associated children who have better language skills and easy temperament with better treatment outcome, although only a small portion of the variance of treatment outcome was accounted for by these variables. There was an association between treatment dropout and parental scores on a personality screening tool relating to their impulsivity.

Conclusions & Implications

Variables identified as predictors of Lidcombe Program treatment outcome were statistically significant, but not clinically significant. They did not account for a clinically substantive portion of treatment outcomes. Findings about parental impulsivity and their relationship with intervention drop-out require replication with prospective methods and comprehensive assessment of parent psychological status. This is particularly important because parents are involved in conducting all early interventions.
