The Effects of Self-Esteem, Coping, and Voice-Related Quality of Life on Communicative Participation Before and After BOTOX® Treatment for Spasmodic Dysphonia.

Objectives/hypothesis: The purpose of this study was to (1) investigate the percent change in communicative participation in individuals with spasmodic dysphonia (SD) pre- and post-BOTOX® treatment; and (2) to investigate if percent change in communicative participation is predicted by change in self-esteem, coping, and/or Voice-Related Quality of Life (V-RQOL) pre- and post-BOTOX® treatment.

Study Design/methods: A cross-sectional study of 49 patients was conducted across three clinics, with each participant completing the Rosenberg Self-Esteem Scale, the Voice Disability Coping Questionnaire (VDCQ), the V-RQOL instrument, and the Communication Participation Item Bank (CPIB) before BOTOX® treatment and 10-14 days following BOTOX® treatment.

Data Analysis: For Research Question 1, a paired t test was applied to test the equality of means for CPIB and to test the pre-post changes among other composite measurements before and after the BOTOX® treatment.
