VOS
The Voice Outcome Survey (VOS), also known as the Voice Handicap Index (VHI), is a 30-item self-report questionnaire assessing the psychosocial, functional, and physical impact of voice disorders on quality of life. Developed by Jacobson and colleagues in 1997, the VOS/VHI has become the standard outcome measure in laryngology and voice pathology for quantifying voice-related disability, monitoring treatment response, and evaluating outcomes following voice therapy or laryngeal surgery.
