OBJECTIVE: To adapt the original singing voice handicap index-10 (SVHI-10) into Hindi and validate it among singers without voice problems and those with dysphonia.
STUDY DESIGN: Cross-sectional analytic study design.
METHOD: The Hindi translation of the original SVHI-10 was conducted following standardized guidelines. The study included 75 singers, comprising two groups: singers without voice problems (NS) (n = 50) and dysphonic singers (DS) (n = 25). Psychometric evaluation of the Hindi SVHI-10 was performed, including assessments of internal consistency, test-retest reliability, criterion validity, and concurrent validity. Sensitivity and specificity of the SVHI-10/Hindi version were determined using receiver operating characteristic (ROC) curve analysis. Additionally, the statistical comparisons were made between both the groups.
RESULT: The Hindi SVHI-10 has excellent internal consistency and test-retest reliability. The Pearson product-moment correlation test indicated that the Hindi SVHI-10 is a reliable tool (r = 0.99, n = 75, P < 0.001). The ROC curve revealed 96.7% sensitivity and 85.1% specificity with a cutoff score of 10. Dysphonic singers scored significantly higher than singers without voice problems on the Hindi version of the singing voice handicap index-10.
CONCLUSION: The Hindi SVHI-10 is a valid, reliable, and sensitive self-report tool that effectively identifies self-perceived singing voice handicaps among Hindi-speaking singers.
