The purposes of this study were to adapt and validate the English version of the pediatric Voice-Related Quality of Life questionnaire into Mandarin Chinese, and to determine the cutoff point for screening children with and without voice disorders.
A total of 377 parents were enrolled from May 2016 to June 2017, including 195 parents of children with voice disorder (patient group) and 182 parents of children without voice disorder (control group). The internal consistency, test-retest, contents and clinical validity, and sensitivity and specificity were analyzed. The clinical cutoff point was determined.
The questionnaire showed strong internal consistency in the patient group (α = 0.89 for the total score, α = 0.88 for the social-emotional domain, and α = 0.81 for the physical functioning domain) and good test-retest reliability (intra-class correlation coefficient = 0.93), as well as moderate to strong contents validity (r = 0.72-0.95). The total score and subscales scores in the patient group were significantly higher than the control group (P < 0.001). The mean score of the physical functioning domain was lower than that of the social-emotional domain in the patient group. The clinical cutoff point was 96.25 (sensitivity = 78.0%, specificity = 100.0%).
The Mandarin Chinese version of pediatric Voice-related Quality of Life questionnaire was a valid and reliable questionnaire, which can be used as a screening test for the pediatric population with and without voice disorders.
本研究旨在将英文版儿童嗓音相关生活质量问卷改编并验证为简体中文版本，并确定用于筛查有无嗓音障碍儿童的临界值。
本研究共纳入了 2016 年 5 月至 2017 年 6 月期间的 377 名家长，其中 195 名儿童患有嗓音障碍（患者组），182 名儿童无嗓音障碍（对照组）。分析了问卷的内部一致性、重测信度、内容效度和临床有效性，以及敏感性和特异性，并确定了临床临界值。
问卷在患者组中表现出较强的内部一致性（总分的 α 值为 0.89，社会情感域的 α 值为 0.88，生理功能域的 α 值为 0.81）和良好的重测信度（组内相关系数为 0.93），以及中等至较强的内容效度（r 值为 0.72-0.95）。患者组的总分和各分量表得分均显著高于对照组（P<0.001）。患者组的生理功能域的平均分低于社会情感域。临床临界值为 96.25（敏感性为 78.0%，特异性为 100.0%）。
简体中文版儿童嗓音相关生活质量问卷是一种有效且可靠的问卷，可作为有无嗓音障碍儿童的筛查工具。
