Validation and Standardization of the Pediatric Voice Symptom Questionnaire: A Double-Form Questionnaire for Dysphonic Children and Their Parents

High internal consistency and good test-retest stability were found. Significant differences between total score of the NP, DP, and NcDP groups were observed both in the children and the parents and also between parental and child score for the NP and NcDP groups (P < 0.001-P = 0.014). Correlations between child and parental scores were found only in the DP groups (r = 0.478; P < 0.001). Based on our results, the PVSQ is a valid and reliable instrument for the autoevaluation of dysphonia in the child population.
