Although existing data reveal that both the source (i.e., self- vs. advocate disclosure) and modality (i.e., verbal or written) of stuttering disclosure yields significant improvements in the perceptions of speech skills and personality characteristics of CWS, there is a paucity of research directly comparing the modality (verbal vs. written) and source (self, mother, teacher) of disclosure statements.

Methods: In this single-case experimental study with ABA design, two participants with dysphagia caused by MS underwent 12 sessions therapy during 6 weeks following a baseline of 4 evaluation sessions. They were evaluated 4 more times in the follow-up phase after therapy sessions. Scores of Mann Assessment of Swallowing Ability (MASA), DYsphagia in MUltiple Sclerosis (DYMUS), and timed test of swallowing capacity were obtained at baseline, during treatment, and in the follow-up phases.
