摘要

目的：本研究旨在评估捷克语版语音障碍指数（VHI-CZ）的信度和构建效度，并确定区分语音障碍患者和非语音障碍个体的截断值。研究设计前瞻性研究，平行组设计。方法对100例成年发声障碍患者进行调查，根据发声障碍的病因（神经源性、功能性和结构性）分为三组。其中，25例患者用于测试-再测试分析，45例患者用于确定对变化的反应性。对照组为51名健康受试者。所有151名受试者均完成了VHI-CZ测试，并进行了视频喉频闪镜检查。分析内部一致性（Cronbach’s alpha）、重测信度（Intra-class Correlation Coefficient， ICC）和结构效度，并确定规范截断值。结果VHI-CZ内部一致性良好（Cronbach α = 0.984），重测信度良好（ICC = 0.95, P < 0.001）。自我评估的语音障碍严重程度与VHI-CZ评分之间存在很强的相关性（Spearman’s ρ = 0.877, P < 0.001）。语音障碍患者与非语音障碍患者的VHI评分差异有统计学意义（Mann-Whitney U检验，P < 0.001）。三个病因亚组（神经源性、功能性和结构性）之间的差异也具有统计学意义（Kruskal-Wallis检验，P < 0.001）。治疗前后VHI-CZ总分差异有统计学意义（Wilcoxon检验，P < 0.001）。通过对受试者工作特征（ROC，约登指数）的分析，发现截断值为13分最适合预选语音障碍个体。结论现有VHI-CZ量表具有良好的信度和结构效度。捷克VHI是临床医生有用和有效的监测工具。

Validation of the Czech Version of the Voice Handicap Index

Objective(s)

The present study aims to evaluate the reliability and construct validity of the Czech version of the Voice Handicap Index (VHI-CZ) and determine the cut-off value to distinguish dysphonic patients from nondysphonic individuals.

Study design

Prospective study, Parallel group design.

Methods

The study investigated 100 adult patients with dysphonia, divided into three groups based on the etiology of the voice problem (neurogenic, functional, and structural). Out of these, 25 patients were used for test-retest analysis, and 45 patients to determine the responsiveness to change. The control group consisted of 51 healthy subjects. All 151 individuals completed the VHI-CZ and were examined with the videolaryngostroboscopy. The internal consistency (Cronbach’s alpha), the test-retest reliability (Intra-class Correlation Coefficient, ICC), and the construct validity were analyzed and the normative cut-off value was determined.

Results

The internal consistency of the VHI-CZ was excellent (Cronbach α = 0.984), and test-retest reliability was also excellent (ICC = 0.95, P < 0.001). The correlation between the self-assessed severity of the voice disorder and the VHI-CZ score was strong (Spearman's ρ = 0.877, P < 0.001). The VHI scores differences between dysphonic and nondysphonic patients were statistically significant (Mann-Whitney U test, P < 0.001). The differences among the three etiological subgroups (neurogenic, functional, and structural) were also statistically significant (Kruskal-Wallis test, P < 0.001). Moreover, the differences in the VHI-CZ total scores between pretreatment and posttreatment were statistically significant (Wilcoxon test, P < 0.001). The cut-off score of 13 points was found, by the analysis of the Receiver Operating Characteristic (ROC, Youden Index), to be most suitable for preselecting dysphonic individuals.

Conclusion

The existing VHI-CZ showed excellent reliability and construct validity. The Czech VHI is a useful and valid monitoring tool for clinicians.
