PMID 37952516WHAT IT FOUND
The Korean Voice Handicap Index-Throat reliably measures throat symptoms alongside voice issues.
It distinguished patients from healthy controls and scored highest in those with primary throat problems, helping clinicians separate voice complaints from throat complaints.
Key findings
01The Korean version of the Voice Handicap Index-Throat showed high internal consistency and stable test-retest reliability over two weeks.
02Scores on the throat scale were significantly higher in patients than in healthy controls, confirming it detects throat symptoms.
03Among patient subgroups, the throat scale scored highest in those with primary throat problems, distinguishing them from patients with neurological voice disorders.

What it does not show
The study only included Korean speakers, so the translation and findings do not apply to other languages. The sample was relatively small and limited to a single hospital, which may not represent all patients with voice or throat disorders.
Declared interests
The authors declared no conflicts of interest. The study was funded by Kosin University.
The easy way to misread this
Do not assume this scale measures general voice quality or throat pathology. It only captures the patient's self-perceived throat symptoms, so it should be used alongside, not instead of, standard voice assessments.
