Abstract
OBJECTIVES: This study aimed to determine the validity and reliability of Bahasa Malaysia version of Voice Handicap Index-10 (mVHI-10). MATERIALS AND METHODS: This cross-sectional study was carried out in the Otorhinolaryngology, Head and Neck Surgery Department of Universiti Kebangsaan Malaysia Medical Centre (UKMMC) from June 2015 to May 2016. The mVHI-10 was produced following a rigorous forward and backward translation. One hundred participants, including 50 healthy volunteers (17 male, 33 female) and 50 patients with voice disorders (26 male, 24 female), were recruited to complete the mVHI-10 before flexible laryngoscopic examinations and acoustic analysis. The mVHI-10 was repeated in 2 weeks via telephone interview or clinic visit. Its reliability and validity were assessed using interclass correlation. RESULTS: The test-retest reliability for total mVHI-10 and each item score was high, with the Cronbach alpha of >0.90. The total mVHI-10 score and domain scores were significantly higher (P < 0.001) in the pathology groups (20.92 ± 8.74) than healthy volunteers (1.54 ± 1.97), depicting excellent discriminant validity. The Kaiser-Meyer-Olkin measure was 0.92, which depicted excellent construct validity. There was a significant positive correlation between the mVHI-10 score and jitter and shimmer result (P < 0.001). CONCLUSIONS: The present study showed good reliability and validity of the mVHI-10 when applied to both healthy volunteers and patients with voice disorders. We recommend the use of the mVHI-10 in daily clinical practice among Bahasa Malaysia-speaking population.
