BACKGROUND/AIMS: Vestibular rehabilitation has an important role in the reduction of symptoms and in the recovery of patients in peripheral vestibular pathologies. Objective and subjective vestibular assessment tools are needed to assess vestibular rehabilitation effectiveness. The aims of the study were to develop the Turkish version of the internationally used Vestibular Rehabilitation Benefit Questionnaire (VRBQ) measure and to demonstrate the reliability and validity properties of the Turkish version in patients with peripheral vestibular hypofunction (PVH).
110 patients with unilateral PVH were included. For the analysis of test-retest reliability, Turkish version of VRBQ developed by translation-back translation method was applied to patients on the day of admission and the day after admission. To assess validity, patients were also evaluated with the VRBQ, Dizziness Handicap Inventory (DHI), Vertigo Symptom Scale-Short Form (VSS-SF), Vertigo Dizziness Imbalance (VDI) Questionnaire.
The VRBQ showed moderate to excellent internal consistency in total score and subscales scores (VRBQ-total Cronbach’s α = 0.91; dizziness α = 0.81; anxiety α = 0.68; motion-provoked dizziness α = 0.89; aypmtoms α = 0.88; health-related quality of life α = 0.87). In the test-retest reliability of VRBQ-total score was excellent (ICC = 0.94). The dizziness, the anxiety, the motion-provoked dizziness, symptoms and the health-related quality of life domains’ ICC were found respectively 0.90, 0.89, 0.84, 0.90, and 0.92. The construct validity of the VRBQ was determined. The VRBQ total was correlated with all parameters (r: 0.308 to –0.699, P < 0.05). The highest positive correlation was found between VRBQ total and DHI-functional (r: 0.680). The highest negative correlation was found between VRBQ total and VDI-total (r: –0.699).
The results suggest that the Turkish version of the VRBQ is reliable and valid for evaluating the vestibular rehabilitation results.
背景/目的：前庭康复在减轻症状和恢复周围性前庭病变患者方面发挥着重要作用。需要客观和主观的前庭评估工具来评估前庭康复的效果。本研究的目的是开发国际上使用的前庭康复效益问卷（VRBQ）的土耳其语版本，并在单侧周围性前庭功能减退症（PVH）患者中展示其可靠性和有效性。
纳入 110 例单侧 PVH 患者。为了分析测试-重测信度，采用翻译-回译法对入院当天和入院次日的患者进行土耳其语版 VRBQ 应用。为了评估有效性，还使用 VRBQ、头晕残障量表（DHI）、眩晕症状量表-短表（VSS-SF）、眩晕失衡量表（VDI）问卷对患者进行评估。
VRBQ 总分和各分量表得分的内部一致性为中等至极好（VRBQ-总分 Cronbach’s α = 0.91；头晕 α = 0.81；焦虑 α = 0.68；运动诱发头晕 α = 0.89；症状 α = 0.88；健康相关生活质量 α = 0.87）。VRBQ 总分的测试-重测信度极好（ICC = 0.94）。头晕、焦虑、运动诱发头晕、症状和健康相关生活质量各分量表的 ICC 分别为 0.90、0.89、0.84、0.90 和 0.92。确定了 VRBQ 的结构效度。VRBQ 总分与所有参数均相关（r：0.308 至-0.699，P < 0.05）。VRBQ 总分与 DHI-功能分量表的相关性最高（r：0.680）。VRBQ 总分与 VDI-总分的相关性最低（r：-0.699）。
结果表明，土耳其语版 VRBQ 可用于可靠有效地评估前庭康复的结果。
