This report concerns operant stuttering therapy programs for five children ranging in age from six to nine years. The programs included programmed desensitization, delayed auditory feedback, and gradual increase in the length and complexity of the speech utterance. Reinforcing events ranged from social reward to points which could be exchanged for toys. The programs varied in length from 15 to 73.3 hours. They were all successful in helping the children to establish fluent speech. Special transfer and maintenance programs were necessary for some of the children. Follow-up measures indicated that the children had maintained their fluency. The value of viewing stuttering as operant behavior was demonstrated.
