To develop and validate the Pediatric Vestibular Symptom Questionnaire (PVSQ) and quantify subjective vestibular symptom (ie, dizziness, unsteadiness) severity in children.
One hundred sixty-eight healthy children (female, n = 91) and 56 children with postconcussion dizziness or a vestibular disorder (female, n = 32), between ages 6 and 17 years, were included. The PVSQ contains questions regarding vestibular symptom frequency during the previous month. The Strengths and Difficulties Questionnaire (SDQ), a brief behavioral screening instrument, was also completed.
The PVSQ showed high internal consistency (10 items; Cronbach α = 0.88). A significant between-group difference was noted with higher (ie, worse) PVSQ scores for children with vestibular symptoms (P < .001); no significant differences were noted between patient groups. The optimal cut-off score for discriminating between individuals with and without abnormal levels of vestibular symptoms was 0.68 out of 3 (sensitivity 95%, specificity 85%). Emotional and hyperactivity SDQ subscale scores were significantly worse for patients compared with healthy participants (P ≤ .01). A significant relationship was noted between mean PVSQ and SDQ (parent-rated version) hyperactivity and total scores for patients (P ≤ .01) and the SDQ (self-rated) emotional, hyperactivity, and total score (P ≤ .01) in healthy controls. However, mean SDQ subscale and total scores were within normal ranges for both groups.
Self-reported vestibular symptoms, measured by the PVSQ, discriminated between children presenting with vestibular symptoms and healthy controls and should be used to identify and quantify vestibular symptoms that require additional assessment and management.
开发并验证儿童前庭症状问卷（PVSQ），并量化儿童主观前庭症状（即头晕、不稳）的严重程度。
共纳入 168 名健康儿童（女性，n=91）和 56 名患有脑震荡后头晕或前庭障碍的儿童（女性，n=32），年龄 6-17 岁。PVSQ 包含过去一个月前庭症状发生频率的问题。还完成了简短的行为筛查工具《长处和困难问卷》（SDQ）。
PVSQ 显示出较高的内部一致性（10 个项目；Cronbach α=0.88）。有前庭症状的儿童的 PVSQ 评分明显更高（即更差），两组之间存在显著差异（P<0.001）；患者组之间无显著差异。区分有和无异常前庭症状个体的最佳截断值为 3 分中的 0.68（敏感性 95%，特异性 85%）。与健康参与者相比，患者的情绪和多动 SDQ 分量表评分明显更差（P≤0.01）。患者的 PVSQ 均值与 SDQ（父母评定版）多动和总分之间存在显著相关性（P≤0.01），以及健康对照组的 SDQ（自我评定）情绪、多动和总分之间存在显著相关性（P≤0.01）。然而，两组的 SDQ 分量表和总分均处于正常范围内。
PVSQ 测量的自我报告前庭症状可区分有前庭症状的儿童和健康对照者，应用于识别和量化需要进一步评估和管理的前庭症状。
