Normative Values for the Children Voice Handicap Index-10 (CVHI-10) and for the Children Voice Handicap Index-10 for...

The objective of this study was to establish normative data and cut-off scores for the Children Voice Handicap Index-10 (CVHI-10) and the Children Voice Handicap Index-10 for Parents (CVHI-10-P) METHODS: For normative data, CVHI-10 and CVHI-10-P questionnaires originally developed in the Italian language were completed by 201 children without dysphonia and with no history of voice disorders, and by 1 of their parents. The results were analyzed for mean, standard deviation (SD), and standard error of the mean (SEM) for both questionnaires. For cut-off values determination, data from 49 dysphonic children and from 1 of their parents were also used. This analysis was based on the sensitivity and specificity indicators of the questionnaires using the "receiver operating characteristic" (ROC) curve.

Analysis of the questionnaires related to healthy children revealed a mean of 0.26 (SD 0.74; SEM 0.06) for CVHI-10 and a mean of 0.15 (SD 0.49; SEM 0.04) for CVHI-10-P for the normative values. ROC curve analysis allowed us to establish the cut-off scores of 2.5 for CVHI-10 and 1.5 for CVHI-10-P.

This study offers normative data for CVHI-10 and CVHI-10-P and provides cut-off values for both questionnaires to distinguish healthy and pathologic responders.
