Treatment responsiveness of the Singing Voice Handicap Index.

OBJECTIVES/HYPOTHESIS: To examine the responsiveness of the previously validated Singing Voice Handicap Index (SVHI) to treatment related changes in patients' singing voice.

STUDY DESIGN: Prospective.

METHODS: Thirty singing patients at a tertiary voice clinic prospectively completed the Voice Handicap Index and SVHI at their initial presentation, pretreatment, and posttreatment.

RESULTS: Patients had lower SVHI scores posttherapy compared with the initial SVHI scores (P
CONCLUSION: The SVHI measures changes in patients' singing vocal health status resulting from treatment and the change correlates with that of other validated instruments.
