Abstract:
This study was done to test the effectiveness of the
Precision Fluency Shaping Program in controlling stuttering
behaviour in adults.
Two sites were chosen, each using the Precision Fluency
Shaping Program to treat stuttering. At each clinic, a
Speech Patbologist made a random selection of the subjects'
pre- and post-therapy video-taped interviews, totalling
20 in all. During the interviews, the clients were asked
questions and re~d a short passage to determine the frequency
of stuttering in natural conversation and in reading.
Perceptions of Stuttering Inventory questionnaires vvere
also filled in before and after therapy.
Two judges were trained to identify stuttering behaviour,
and were given an inter-rater reliability test at
selected intervals throughout the study. Protocols",:m.a;d;6
of each interview tape, were scored for (a) stuttering
behaviour and (b) words spoken or read.
An Analysis of Variance Repeated Measures Test was
used to compare before and after scores of conversations,
readings, and Perceptions of Stuttering Inventory to determine
whether the Precision Fluency Shaping Program controlled
stuttering behaviour significantly. A Pearson
R Correlation Test was also administered to determine if
a relationship existed bet\veen Perceptions of Stuttering
Inventory and (i) conversation and (ii) reading scores.
