- Abstract
- The aim of our study was to validate a Pediatric Voice Symptom Questionnaire (PVSQ) presenting with a parallel form for children and their parents. The items of the questionnaire were elaborated from the results of structured interviews with dysphonic children (DP) and normophonic children (NP) and their mothers and were tested for feasibility in a pilot study involving 42 normophonic children aged 5-13 years. The items were then administered in a test-retest mode to 333 children and their parents (154 boys and 179 girls with a mean age of 9 years, standard deviation: 1.8); 45 consulting DP, 34 nonconsulting dysphonics (NcDP), 163 NP, and 91 others. Classical statistical analyses and an item response modeling approach were used to analyze the results. 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. © 2012 The Voice Foundation.
