Objectives: The purpose of this study was to cross-culturally adapt and validate the Hong Kong Chinese version of the Children's Voice Handicap Index-10 for Parents (CVHI-10-P(HK)), a parent-proxied quality of life (QOL) questionnaire that pairs with the Children's Voice Handicap Index-10 (CVHI-10(HK)). Method: The English version of the (CVHI-10-P(HK)) underwent forward-backward translation and pretesting. Content validity was computed from an expert panel rating on relevance and test-retest reliability was obtained from parents and/or guardians of six dysphonic and five vocally-healthy children. Other validity and reliability measures were analyzed from CVHI-10-P(HK) completed by parents and/or guardians of 28 dysphonic and 35 vocally-healthy children who had completed CVHI-10(HK). Results: The CVHI-10-P(HK) demonstrated excellent internal consistency (α = 0.091), excellent content validity (item- and scale-level content validity indices = 1.00), good construct validity (between group difference in total CVHI-10-P(HK) score: t(30.904) = -6.449, P < 0.001, Cohen's d = 1.709) and excellent test-retest reliability (r = 0.966, P < 0.001). Criterion validity analysis showed a moderate correlation between the total CVHI-10-P(HK) score and auditory-perceptual ratings on overall severity (r = 0.515, P < 0.001). Area under the curve of the receiver operating characteristic plot was found to be 0.855. The CVHI-10-P(HK) has excellent intrinsic accuracy. A cutoff of score of four may be adopted for the optimal sensitivity and specificity match. A moderate correlation was found between the total scores of CVHI-10-P(HK) and CVHI-10(HK) (r = 0.684, P < 0.001). Conclusion: The CVHI-10-P(HK) is a valid tool that measures QOL of dysphonic children from the parents’ perspective. It is recommended to be used in parallel to the CVHI-10(HK) as part of a comprehensive voice assessment for children in Hong Kong.
