Questionnaire Analysis and Purpose

The Singing Voice Handicap Index (SVHI-81) was developed and standardized in 2007 by Cohen and colleagues. It is an enhanced version of the Voice Handicap Index (VHI) that specifically focuses on the singing voice. This index was created as an assessment tool designed to evaluate and understand singers’ concerns regarding their vocal health.

Question Scoring

The pilot version of the SVHI included a total of 81 items, which after testing was reduced to a final form consisting of 36 questions. These questions are categorized into three subscales:
Functional (10 items)
Physical/Organic (10 items)
Emotional (16 items)
Each item is rated using a 5-point Likert scale from 0 (Never) to 4 (Always). Additionally, a short form of the SVHI was developed by the same team in 2009, consisting of 10 items.

Statistical Analysis

The total score can range from 0 to 144. A higher score indicates a greater likelihood of significant voice disorder.

Validity and Reliability

The SVHI is considered a valid and reliable tool for measuring an individual’s perception of dysphonia. It has been translated into several languages, including Greek by the research team of Chelidoni in 2008. Results have shown high internal consistency and strong reliability (Cronbach’s α = 0.97).
