The Singing Voice Handicap Index-10 (SVHI-10): A Systematic Review

To systematically synthesize the literature on the Singing Voice Handicap Index-10 (SVHI-10), a concise patient-reported outcome measure designed specifically for singers, this study followed PRISMA 2020 guidelines. Databases including PubMed, Scopus, Web of Science, and Embase were searched from inception to March 2026. Peer-reviewed studies reporting development, validation, reliability, validity, normative values, minimal clinically important difference (MCID), or clinical applications were included. Quality was assessed using the COSMIN checklist. Of 152 records screened, 22 studies were included. The original SVHI and abbreviated SVHI-10 showed excellent psychometrics (Cronbach’s α ≥ 0.94). Validated adaptations exist in at least eight languages, including Mandarin, Italian, Turkish, Kannada, Persian, and Hindi. Normative data yielded pooled means of 8.38–9.13 in healthy singers, with scores ≥20 considered abnormal. The MCID was established as 9.5–10 points. The SVHI-10 demonstrates superior singer-specific sensitivity and responsiveness compared with the VHI-10. The SVHI-10 is a reliable, valid, and clinically actionable PROM. Its Mandarin version (MSVHI-10) is particularly relevant for Chinese populations. Future research should focus on longitudinal responsiveness and non-Western singing styles.
