This study aims to validate, cross-culturally, and linguistically adapt the Vocal Fatigue Index (VFI) into Arabic.
Cross-sectional study.
The VFI was translated into Arabic, reverse translated, and content validated. To assess its psychometric properties, 398 patients with voice disorders (199 males, 199 females, mean age=46.2 ± 15.0years) and 121 vocally healthy controls (57 males, 64 females, mean age=42.1 ± 6.9years) completed the VFI-Arabic. We calculated internal consistency and test-retest reliability using Cronbach's alpha and intraclass correlation (ICC) coefficients. Independent sample t tests determined mean factor score differences between groups, while receiver operator characteristic curves analyzed sensitivity, specificity, and cut-off scores for the three factors.
The overall Cronbach's alpha was 0.95, across all factors combined, it was 0.68; and for factors 1, 2, and 3, it was 0.95, 0.91, and 0.91, respectively. Test-retest reliability for the subscales was excellent (ICC: 0.97, 0.91, 0.82 for factors 1, 2, and 3). Mean subscale scores were significantly higher in the voice-disordered group than in controls. The area under the curve for factors 1, 2, and 3 was 0.824, 0.759, and 0.646, respectively. Best cut-off scores were ≥14.5 (69.8% sensitivity, 83.1% specificity) for factor 1, ≥3.5 (66.3% sensitivity, 74.4% specificity) for factor 2, and ≥5.5 (60.1% sensitivity, 64.5% specificity) for factor 3.
The VFI-Arabic is a valid and reliable tool for identifying and quantifying vocal fatigue symptoms in Arabic speakers.
本研究旨在对嗓音疲劳指数（VFI）进行跨文化、语言适应性的阿拉伯语验证。
横断面研究。
将VFI翻译成阿拉伯语，进行回译并进行内容效度验证。为评估其心理测量特性，398例嗓音障碍患者（199例男性，199例女性，平均年龄 = 46.2 ± 15.0岁）和121名嗓音健康对照者（57例男性，64例女性，平均年龄 = 42.1 ± 6.9岁）完成了阿拉伯语版VFI。我们使用克朗巴哈系数和组内相关系数（ICC）计算内部一致性和重测信度。独立样本t检验确定组间平均因子得分差异，而受试者工作特征曲线分析三个因子的敏感性、特异性和临界分数。
总体克朗巴哈系数为0.95，所有因子合并后为0.68；因子1、2和3分别为0.95、0.91和0.91。分量表的重测信度极佳（因子1、2和3的ICC分别为0.97、0.91和0.82）。嗓音障碍组的平均分量表得分显著高于对照组。因子1、2和3的曲线下面积分别为0.824、0.759和0.646。因子1的最佳临界分数≥14.5（敏感性69.8%，特异性83.1%），因子2≥3.5（敏感性66.3%，特异性74.4%），因子3≥5.5（敏感性60.1%，特异性64.5%）。
阿拉伯语版VFI是识别和量化阿拉伯语使用者嗓音疲劳症状的有效且可靠的工具。
