Efficacy of the Modifying Phonation Intervals (MPI) Stuttering Treatment Program With Adults Who Stutter
American Journal of Speech-Language Pathology
|January 31, 2015
Summary
The Modifying Phonation Intervals (MPI) treatment for stuttering was more effective than prolonged speech therapy in adults. MPI helped more participants achieve fluent speech and identify as normal speakers.
Area of Science:
- Speech-language pathology
- Communication sciences and disorders
- Adult stuttering treatment
Background:
- Stuttering affects adults, impacting communication and self-perception.
- Standard treatments like prolonged speech exist, but new approaches are explored.
Purpose of the Study:
- To compare a new adult stuttering treatment, Modifying Phonation Intervals (MPI), with the standard prolonged speech therapy.
- To assess the effectiveness of MPI in reducing stuttered speech and improving self-identification.
Main Methods:
- Twenty-seven adults who stutter were randomly assigned to MPI or prolonged speech treatment.
- Speech and related variables were assessed in various speaking situations for treatment completers.
Main Results:
- 14 participants achieved speech similar to fluent adults post-treatment.
- Successful participants showed improved self-identification and changes in phonation intervals.
- More participants succeeded with MPI (11) than prolonged speech (3).
Conclusions:
- Both treatments yielded similar outcomes for successful participants.
- MPI demonstrated greater effectiveness in helping adults modify speech behaviors for successful stuttering treatment.
