Clinically Significant Changes Following Stuttering Treatment

Glyndon Riley, Gerald Maguire and Jeanna Riley

Traditionally reduction in stuttering following treatment has been expressed in terms of percent syllables stuttered (%SS) or scores on a severity scale. Even though it is necessary to limit the end measure to describe statistical significance, additional measures are needed to describe clinical significance. We propose using self-report measures such as the Subjective Screening of Stuttering Severity, Avoidance, and Locus of Control; the Perception of Stuttering Inventory, etc. to capture changes that may not be reflected in the %SS.
