Evaluating the efficiency of modified habit reversal for reducing speech disfluencies

Recent literature supports using a multi-component awareness training procedure to decrease speech disfluencies for college students. However, this procedure can be time-consuming and is likely not feasible in practical settings, such as college classrooms. The present study focused on the time required to decrease speech disfluencies. In Experiment 1, we conducted a component analysis of awareness training, and we evaluated the efficacy and efficiency of an awareness enhancement device in Experiment 2. We found that in vivo speech practice may be sufficient for reducing disfluencies for some students, but a treatment package including both video and in vivo training is more likely to result in marked behavior change. We also found that in vivo speech practice with the addition of an awareness enhancement device was effective for four of five participants; however, training time was comparable to the combined treatment package.
