Journal of voice : official journal of the Voice Foundation 2023 SepTo determine reliability and validity of the European Portuguese pVHI version (pVHI-EP). Cross-sectional design. The pVHI-EP and the talkative and global voice assessment scales were administered to the caregivers of children aged from 3 to 16 years old with and without dysphonia. Reliability (internal consistency and test-retest) was analyzed. The validity analyses performed were: (1) content validity by analyzing the percentage of missing data; (2) construct validity with intraclass correlation coefficients among pVHI-EP domains and overall score; (3) concurrent validity was conducted between pVHI-EP, the caregivers' judgment of the child's voice severity on a visual analog scale and the Speech-Language Pathologist perceptual voice assessment; (4) known-groups validity between children with and without dysphonia, and (5) predictive validity by calculating receiver operating characteristics, sensitivity and specificity and determining cut-off points. A total of 283 children (61.5% boys, mean age 8.3 years) participated in the study. The pVHI-EP showed an excellent internal consistency for the pVHI-EP total data. Strong to moderate test-retest reliability confirms pVHI-EP reproducibility. Excellent to good intraclass correlation coefficients between the pVHI-EP overall and the domains confirms its construct validity. Weak to moderate concurrent validity with visual analog scale and Speech-Language Pathologist perceptual voice assessment was confirmed. The pVHI-EP significantly distinguished two groups of different voice conditions. A cut-off point of 10.5 with 95.9% sensitivity and 92.5% specificity was determined for the overall score of the pVHI-EP. The pVHI-EP is a reliable and valid caregiver voice outcome tool for EP children with dysphonia. Copyright © 2021 The Voice Foundation. Published by Elsevier Inc. All rights reserved.
