Objectives: Dysphonia is a common pathologic condition in childhood. Multidimensional voice assessments are recommended in voice assessments for children. Recently, a childbased self voice assessment has been developed. This study assessed the reliability and validity of the Korean version of the CVHI-10 as a reliable self-administered voice assessment.
Methods: A total of 100 school age children with voice disorders, aged 7-12 years and 100 age and gender-matched children with no voice disorders and their 200 parents participated in this study. Internal consistency was calculated through Cronbach’s α coefficient and the test-retest reliability of the Korean version of the CVHI-10 was estimated.
Results: The Korean version of the CVHI-10 revealed a high internal consistency ; α= .911 for children, α= .876 for parents as well as good test-retest reliability r= .759 for children, r= .762 for their parents. There was a strong correlation between the Korean version of the CVHI-10 and the K-pVHI in both children and their parents’ responses (r= .759, r= .752), respectively. The Korean version of the CVHI-10 showed a low significant correlation with the acoustical measurements of %jitter and %shimmer, and the ‘G’ score of GRBAS scale. Furthermore, in the K- CVHI-10 results obtained from children, the cut-off score was found to be 75% positive predictive value and 69% negative predictive value, based on 3.50 points, and the area under the curve was shown to be .683. Similarly, in their parents, the cut-off score was found to be 90.6% positive predictive value and 86.2% negative predictive value, based on 3.50 points, and the area under the curve was shown to be .95.
Conclusion: The Korean version of the CVHI-10 can be a useful voice assessment tool as a diagnostic test as well as a screening tool for children and their parents to identify voice problems and provide appropriate intervention with objective voice assessment.
