The calculated sample size of 215 primary school teachers was gathered from 11 schools by purposive sampling. Construct validity using confirmatory factor analysis (CFA) on LISREL software version 8.8, and convergent validity, discriminant validity, and composite reliability were assessed. Criterion validity was assessed by a speech-language therapist (SLT) and confirmed by acoustic measurements using PRAAT software 6.1.16. A cutoff value to screen for voice disorders was determined from the ROC curve. The assessment of reliability was by Cronbach\u2019s alpha, and test-retest reliability by Spearman correlation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The three-factor model assessed for CFA demonstrated a medium fit. Factor loadings exceeded the desired value of 0.4, except for item 10. Convergent and discriminant validity were medium. Reliability was satisfactory with values above 0.7 for composite reliability, Cronbach\u2019s alpha, and test-retest reliability. The cutoff value for screening voice disorders, determined from the ROC curve, was 14 (sensitivity 84%, specificity 72.5%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The Sinhala version of the VHI-30 is a reliable tool with medium validity.
