魁北克法国人口（VHI

语音障碍指数（VHI）是一种广泛认可的自我管理调查表，旨在评估患者对与语音相关的残疾的感知。它考虑了发声困难的物理，功能和情感影响。VHI已被翻译成多种语言并经过验证，包括欧洲法语。我们研究的目的是翻译，改编和验证魁北克法语的VHI新版本。

原始的VHI由四位专业翻译人员（包括一名言语病理学家）进行正向和反向翻译，翻译成魁北克法语（QF）。在6名患者和7名言语病理学家的焦点小组中检查了所得VHI-QF的内容效度。另对154名语音障碍患者和150名健康对照者的样本进行了评估，以评估新问卷的收敛性和判别有效性以及内部一致性。还评估了所有患者对问卷的满意度，以及子样本的重测信度和响应度。

VHI-QF与发声困难严重程度显示中等程度的相关性，表明有足够的收敛效度。总分和次级量表分数还表现出足够的区分患者和对照组的能力（区分效度），内部一致性高，重测信度好。治疗前和治疗后VHI-QF得分的分析表明，对语音治疗有足够的反应性。患者总体上对问卷感到满意。

VHI-QF是一种有效，可靠且临床上有用的自我报告工具，可用于评估魁北克法国人口的声音障碍的严重程度和变化。因此，该调查表可用于临床和研究环境。

Background and Objectives

The Voice Handicap Index (VHI) is a widely recognized, self-administered questionnaire, designed to evaluate patients' perception of voice-related disability. It takes into consideration the physical, functional and emotional impacts of dysphonia. The VHI has been translated and validated in many languages, including European French. The purpose of our study is to translate, adapt and validate a new version of the VHI in Quebec French.

The original VHI was translated into Quebec French (QF) by forward and backward translations by four professional translators, including a speech-language pathologist. The content validity of the resulting VHI-QF was examined in focus groups with six patients and seven speech-language pathologists. Another sample of 154 patients with voice disorders and 150 healthy controls allowed evaluation of the new questionnaire's convergent and discriminant validity, and internal consistency. Satisfaction toward the questionnaire was also evaluated for all patients, as well Test-retest reliability and responsiveness for a sub-sample.

The VHI-QF showed a moderate correlation with dysphonia severity level, indicating adequate convergent validity. Both total and subscale scores also exhibited adequate ability to discriminate between patients and controls (discriminant validity), high internal consistency, and good test-retest reliability. The analysis of pre- and post-treatment VHI-QF scores revealed adequate responsiveness to voice treatment. Patients were overall satisfied with the questionnaire.

The VHI-QF is a valid, reliable and clinically useful self-reported tool to evaluate the severity and change of voice disorders in Quebec French population. Therefore this questionnaire can be used in clinical and research contexts.
