Abstract

Background: Vestibular Activities and Participation Measure (VAP) subscales assess the effect of vestibular disorders on activity and participation. This study aimed to perform the cross-cultural adaptation and assess the validity, internal consistency, reliability, and measurement error of the Brazilian version of VAP subscales.

Methods: The cross-cultural adaptation followed the translation, synthesis, back-translation, review by a committee of experts, and pretesting phases. Structural validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while Spearman's correlation between VAP subscales and the Dizziness Handicap Inventory (DHI) was used to assess construct validity. Cronbach's alpha measured internal consistency. Intraclass correlation coefficient (ICC) assessed intra- and inter-rater reliability, and measurement error was calculated by using the standard error of measurement (SEM) and minimal detectable change (MDC).

Results: Additional information was included in the Brazilian version of the Vestibular Activities and Participation measure (VAP-BR) after approval by one of the developers of the instrument to improve the understanding among individuals. One factor was found in the EFA for each subscale with 50% explained variance. Regarding CFA, the subscales 1 (S1) and 2 (S2) presented, respectively, adequate model fit indices (ie, comparative fit index of 0.99 and 0.97, and standardized root mean square residual of 0.04 for both subscales), but a very low factor load in item 6 of S1 (0.08). Chronbach's alpha was 0.80 (S1) and 0.82 (S2). For intra-rater assessment, the S1 and S2 presented an ICC of 0.87 and 0.90, SEM of 0.01 and 1.16, and MDC of 0.39 and 0.46, respectively. When assessed by 2 different raters, SEM values were 1.03 and 1.53, and MDC values were 2.85 and 4.23 for S1 and S2, respectively; both subscales showed an ICC of 0.92. Correlations between DHI and VAP subscales presented coefficients above 0.57.

Conclusion: The Brazilian version of VAP subscales presents good measurement properties and may assist health professionals in identifying activity limitations and participation restrictions in individuals with vestibular disorders.

巴西版前庭活动和参与度测量：跨文化适应性、有效性和可靠性。

背景：前庭活动和参与测量（VAP）分量表评估前庭障碍对活动和参与的影响。本研究旨在对巴西版 VAP 分量表进行跨文化改编，并评估其有效性、内部一致性、可靠性和测量误差：跨文化改编经过了翻译、综合、回译、专家委员会审查和预测试阶段。结构效度采用探索性因子分析（EFA）和确认性因子分析（CFA）进行评估，而 VAP 分量表与头晕障碍量表（DHI）之间的斯皮尔曼相关性则用于评估结构效度。Cronbach's alpha 用于测量内部一致性。类内相关系数（ICC）评估了评分者内部和评分者之间的可靠性，测量误差则通过测量标准误差（SEM）和最小可检测变化（MDC）来计算：在巴西版前庭活动和参与度测量（VAP-BR）中加入了更多信息，这些信息得到了该工具开发者之一的认可，以增进个人之间的理解。在 EFA 中，每个子量表都有一个因子，解释方差为 50%。就 CFA 而言，子量表 1（S1）和子量表 2（S2）的模型拟合指数分别为 0.99 和 0.97，两个子量表的标准化均方根残差均为 0.04，但 S1 第 6 项的因子载荷很低（0.08）。Chronbach'sα为 0.80（S1）和 0.82（S2）。在评分者内部评估方面，S1 和 S2 的 ICC 分别为 0.87 和 0.90，SEM 分别为 0.01 和 1.16，MDC 分别为 0.39 和 0.46。由两名不同评分者进行评估时，S1 和 S2 的 SEM 值分别为 1.03 和 1.53，MDC 值分别为 2.85 和 4.23；两个分量表的 ICC 均为 0.92。DHI 与 VAP 分量表之间的相关系数高于 0.57：巴西版 VAP 分量表具有良好的测量特性，可帮助医疗专业人员识别前庭障碍患者的活动限制和参与限制。
