It is known that children may recover from stuttering without formal treatm
ent during the First years after onset. Consequently, the timing of profess
ional, early stuttering intervention is a pressing issue in speech-language
pathology. This report presents data pertinent to this issue For 261 presc
hool-age children who received the Lidcombe Program of early stuttering int
ervention. OF these children, 250 completed the program and were considered
by their clinicians to have been treated successfully For the children who
were treated successfully logistical regression analyses were used to dete
rmine whether age, gender, period from onset to treatment, and stuttering s
everity related systematically to the time required for treatment. The pres
ent data confirmed previous reports that a median of 11 clinic visits was r
equired to achieve zero or near-zero stuttering with the Lidcombe Program.
Results were also consistent with a preliminary report of 14 children (C. W
. Starkweather & S. R. Gottwald, 1993) showing a significant relation betwe
en stuttering severity and the time needed for treatment, with children wit
h more severe stuttering requiring longer treatment times than children wit
h less severe stuttering. However, results did not associate either increas
ing age or increased onset-to-treatment intervals with longer treatment tim
es. This Finding is not consistent with the Starkweather and Gottwald repor
t, which linked advancing age with longer treatment rime. In Fact, the pres
ent data suggest that, For a short period after stuttering onset in the pre
school years, a short delay in treatment does not appear to increase treatm
ent time. An important caveat to these data is that they cannot be generali
zed to late childhood or early adolescence. The present findings are discus
sed in relation to natural recovery from stuttering.
