Abstract
This study applied the Fishbein and Ajzen model of attitude, intention and behaviour to stammerers’ evaluations and use of their disfluent speech and a fluency controlling speech pattern. Subjects were eight adult stammerers who participated in an eight week group therapy programme. The model advocated a positive relationship between subjects’ attitudes and intention to use their own disfluent speech and a fluency controlling technique. A positive relationship was also hypothesized between their intentions to use disfluent speech and their intentions to use the fluency controlling technique, and their fluency gains measured after the completion of the therapy programme. The results supported the relationships proposed by the model and confirmed its value in predicting fluency gains on the basis of pre therapy attitude and intention scores.
