The Tinnitus Functional Index (TFI) is a recent self-report instrument for tinnitus with potential advantages over other existing instruments, including a demonstrated high responsiveness. The objectives of this study were to translate and cross-culturally adapt the TFI into Swedish and to investigate its validity and reliability.
The development of the Swedish version (TFI-SE) followed published guidelines on cross-cultural adaptation of health questionnaires. Validity and reliability was investigated by correlating responses on the TFI-SE with other tinnitus measures [Tinnitus Handicap Inventory (THI) and visual analogue scale (VAS)] and a scale measuring anxiety and depression (HADS).
Consecutively recruited tinnitus patients (n = 100) from four Swedish clinics completed the questionnaires. The mean age of the sample was 51 years (SD =17).
The internal consistency of the TFI-SE was good (α = 0.95) and the test-retest reliability was high (ICC =0.93). Our results supported the eight-factor structure proposed for the original TFI, and a high correlation between the TFI-SE and the THI (r = 0.8; p < 0.01) and lower correlations between the TFI-SE and the HADS-D (r = 0.60; p < 0.01) and HADS-A (r = 0.59; p < 0.01) confirmed satisfactory convergent and discriminant validity.
We found that the Swedish translation and cross-cultural adaptation of the TFI is valid and reliable for use with adult tinnitus patients.
耳鸣功能指数（TFI）是一种最新的耳鸣自我报告工具，与其他现有工具相比具有潜在优势，包括已证实的高反应性。本研究的目的是将TFI翻译成瑞典语并进行跨文化调适，并调查其有效性和可靠性。
瑞典语版本（TFI-SE）的开发遵循已发表的关于健康问卷跨文化调适的指南。通过将TFI-SE的回答与其他耳鸣测量方法[耳鸣障碍量表（THI）和视觉模拟量表（VAS）]以及测量焦虑和抑郁的量表（HADS）进行关联，来研究有效性和可靠性。
从瑞典四家诊所连续招募的耳鸣患者（n = 100）完成了问卷。样本的平均年龄为51岁（标准差=17）。
TFI-SE的内部一致性良好（α = 0.95），重测信度较高（ICC = 0.93）。我们的结果支持了原始TFI提出的八因素结构，TFI-SE与THI之间的高相关性（r = 0.8；p < 0.01）以及TFI-SE与HADS-D（r = 0.60；p < 0.01）和HADS-A（r = 0.59；p < 0.01）之间较低的相关性证实了令人满意的聚合效度和区分效度。
我们发现TFI的瑞典语翻译和跨文化调适对于成年耳鸣患者是有效且可靠的。
