The aim of this study was to develop a shortened German version of the Singing Voice Handicap Index (SVHI). The SVHI is a one-dimensional instrument for self-assessment of a voice disorder in singers. The questionnaire developed in the USA comprises 36 items and has been available in a validated German version since 2013.
Bicentric data from a total of 200 patients formed the basis for item analysis and selection. Using corrected item-total correlations, 12 items were selected for the abridged version. The internal consistency was calculated. The SVHI-12 was subsequently validated in 97 vocal patients and 105 vocally healthy singers (control group) using the test-retest procedure.
The SVHI-12 achieved a good internal consistency (Cronbach's alpha = 0.93) and a good test-retest reliability (intra-class correlation r = 0.88 ; p < 0.001). The patients had significantly higher overall scores (18 ± 13 vs. 7 ± 6) compared to the healthy control group. The SVHI-12 overall score correlated significantly positively with the severity of the voice disorder as reported by the patient (r = 0.68; p < 0.001). As a threshold value above which a voice can be described as disturbed, a total score > 7 points was calculated using receiver operating curve analysis. As an indication of a voice disorder, a sensitivity of 81% and a specificity of 71% is thus achieved (Youden index 0.523, area under the curve 0.827, 95% confidence interval 0.769-0.885).
The shortened SVHI has similarly good psychometric characteristics to the original SVHI. With the SVHI-12, a valid and effective instrument for the detection of singing voice disorders is available for German-speaking countries.
本研究的目的是开发一个简化的德语版歌唱嗓音障碍指数（SVHI）。SVHI是一种用于歌手嗓音障碍自我评估的一维工具。美国开发的问卷包含36个项目，自2013年起已有经过验证的德语版本。
来自总共200名患者的双中心数据构成了项目分析和选择的基础。使用校正后的项目总分相关性，为简化版选择了12个项目。计算了内部一致性。随后，通过重测程序在97名嗓音患者和105名嗓音健康的歌手（对照组）中对SVHI-12进行了验证。
SVHI-12具有良好的内部一致性（克朗巴哈系数α = 0.93）和良好的重测信度（组内相关系数r = 0.88；p < 0.001）。与健康对照组相比，患者的总体得分显著更高（18 ± 13 vs. 7 ± 6）。SVHI-12总体得分与患者报告的嗓音障碍严重程度显著正相关（r = 0.68；p < 0.001）。使用受试者工作特征曲线分析计算出总分> 7分作为嗓音可被描述为有障碍的阈值。作为嗓音障碍的指标，由此实现了81%的敏感性和71%的特异性（约登指数0.523，曲线下面积0.827，95%置信区间0.769 - 0.885）。
简化后的SVHI具有与原始SVHI相似的良好心理测量学特征。借助SVHI-12，为德语国家提供了一种用于检测歌唱嗓音障碍的有效工具。
