目的 评估中文版儿童前庭症状量表（C-PVSQ）的信度和效度，为儿童前庭相关头晕或眩晕症状的评估提供量化工具。方法 采用跨文化翻译法将儿童前庭症状量表（PVSQ）翻译成中文版本，量表共包含10题，每题根据患儿症状进行评分，总分30分。选取2023年11月至2024年6月于听力障碍及眩晕诊治中心门诊就诊的85 例以头晕、眩晕或平衡障碍为主诉的6~17岁患儿作为研究对象，进行C-PVSQ信度和效度的评估。结果 C-PVSQ总评分的重测信度系数为0.97>0.70（P<0.01）；内部一致性检验Cronbach α系数为0.83；对所有患儿的评分结果进行探索性因子分析，KMO值为0.801，Bartlett球形检验P<0.001，提取特征根值>1的因子，得到3个公因子，分别为“头晕因子”（第1和第4题），“平衡因子”（第2、8、9题），“眩晕相关症状”（第3、6、7、10题），总累计贡献率为66.1%。结论 C-PVSQ量表具有良好的信度和效度，可初步用来评估儿童头晕、眩晕或平衡障碍的症状以及严重程度。

Objective To assess the reliability and validity of the Chinese version of pediatric vestibular symptom questionnaire (C-PVSQ) and to establish a quantitative tool for the assessment of vestibular related dizziness or vertigo symptoms in children. Methods The PVSQ was translated into Chinese using the cross-cultural translation method. The questionnaire consisted of 10 questions, each of which was scored according to the symptoms of the children, with a total score of 30 points. A total of 85 children aged 6-17 years old with dizziness, vertigo or balance disorder who visited the clinic of Hearing Impairment and vertigo Diagnosis and Treatment Center from November 2023 to June 2024 were selected as the study objects. The reliability and validity of C-PVSQ were evaluated. Results The test-retest reliability coefficient of the total score of C-PVSQ was 0.97>0.70 (P<0.01); Cronbach α coefficient of internal consistency test was 0.83. By exploratory factor analysis, the KMO value was 0.801, and Bartlett sphericity test showed P<0.001. Factors with feature root value >1 were extracted, and three common factors were obtained, namely "dizziness factor" (questions 1 and 4), "balance factor" (questions 2, 8 and 9), and "vertigo-related symptoms" (questions 3, 6, 7 and 10), with a total cumulative contribution rate of 66.1%. Conclusions The C-PVSQ exhibits strong reliability and validity and can effectively assess symptoms and severity related to dizziness, vertigo, or balance disorders in children.
