Introduction
This study compares the efficacy of two treatment approaches, what are they?
Modifying Phonation Intervals and Prolonged Speech
How many research questions did the authors investigate?
Three.
This consisted of 27 PWS and 8 PWNS.
Participants.
The first research question found that both groups reduced their stuttering to this percentage.
1% syllables stuttered
The amount of time that the vocal folds are vibrating to produce phonation.
Phonation Interval
True or false: the authors investigated whether MPI and PS changed the speech performance and self-identification outcomes of the participants.
True.
To be selected, PWS must report chronic stuttering and this...
3% syllables stuttered
This number of participants did not complete all five phases.
Thirteen.
A therapy approach that reduces the frequency of short phonation intervals.
Modified Phonation Intervals
True or false: the authors investigated if a difference in phonation intervals predicted success in the short-term maintenance phase.
False.
This group of participants did not participate in the treatment stage.
Control group / PWNS
True or false: the third research question found that successful participants and clinicians rated their speech in similar ranges.
True.
A therapy approach that increases the duration of a PWS's phonation time.
Prolonged Speech
The authors investigated whether successful completion of the program resulted in similar measurements to what group of people?
Fluent speakers.
The two treatment groups participated in this number of treatment phases.
Five.
This treatment group saw more than twice the proportion of its participants successfully complete the program than the other group.
