Summary
The new Children's Voice Questionnaire (CVQ-10) is a reliable and valid tool for assessing voice handicap in children. It effectively distinguishes between children with and without dysphonia, aiding clinical evaluation.
Area of Science:
- Pediatric Otolaryngology
- Speech-Language Pathology
- Voice Science
Background:
- Childhood voice disorders can significantly impact a child's quality of life.
- Accurate and reliable assessment tools are crucial for identifying and managing pediatric voice conditions.
- Existing questionnaires may not be optimally suited for self-administration by children.
Purpose of the Study:
- To introduce and validate the Children's Voice Questionnaire-10 (CVQ-10), a novel 10-item self-administered tool.
- To assess the validity and reliability of the CVQ-10 in quantifying children's voice handicap.
- To establish the CVQ-10's utility in differentiating between dysphonic and non-dysphonic children.
Main Methods:
- An observational, prospective, cross-sectional study design was employed.
- The CVQ-10 was developed by selecting items from the full CVQ based on Cohen's d scores.
- The questionnaire was administered to 208 children (aged 6-17 years), with concurrent parent-reported data using the Pediatric Voice Handicap Index (pVHI).
- Test-retest reliability was assessed on a subset of 30 children, and validity was evaluated against the full CVQ in another subset of 30 children.
Main Results:
- The CVQ-10 demonstrated high internal consistency (Cronbach's α = 0.94) and excellent test-retest reliability (r = 0.91).
- A significant difference was observed between dysphonic and non-dysphonic groups (t[206] = 17.00, P < 0.001), with a cutoff score of nine points.
- A strong positive correlation was found between children's self-reports on the CVQ-10 and parents' pVHI scores (r = 0.766, P < 0.001).
Conclusions:
- The CVQ-10 is a valid and reliable instrument for assessing voice handicap in children.
- The findings confirm the single-factor structure of the CVQ-10, indicating children can reliably report their voice handicap.
- The CVQ-10 serves as a brief, user-friendly tool for evaluating dysphonic children in clinical and research settings.

Cochran's Q Test is a nonparametric statistical test used to determine if there are potential differences in the outcomes of three or more related groups on a binary (yes/no) or dichotomous outcome. It is essentially an extension of the McNemar Test, which is limited to two related samples - Cochran's Q test can handle three or more related samples, making it more versatile in scenarios where subjects are measured under multiple conditions. The test statistic follows a Chi-Square distribution,...

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
