The Voice Handicap Index (i. e., VHI) is one of the most reliable standardized self-evaluation assessments in diagnosis of voice disorders. That tool is the most used in daily clinic. In 2007, the VHI was adapted to the singing population, called 'VHI adapté aux chanteurs'. The aim of our study was to investigate the reliability and validity of the German version of the VHI adapted to the singing voice.
113 German singers (41 males and 72 females) with diverse singing styles and profession were included in the study. They were divided into 2 groups: a test-group (n=20) with self-perceived vocal complaints and a control-group (n=93) without vocal complaints. Statistical analysis to measure the reliability and validity was conducted with the Cronbach's alpha (i. e., Cron. α), independent t-test and receiver operating characteristics as well likelihood ratio, respectively.
Reliability was confirmed by acceptable Cron. α (0.713-0.850) for each of the sub-scales and total score. The validity between the 2 groups showed high significant differences for each of the sub-scales and total score by which the test-group indicated higher scores than the control-group. Only the construct validity revealed no clear results.
The VHI adapted to the singing voice is suited as reliable and valid standardized evaluation tool, but the diagnostic accuracy has to be investigated again because of too high inaccuracy in the interpretation of the outcome of the present data.
嗓音障碍指数（即VHI）是诊断嗓音疾病最可靠的标准化自评评估工具之一。该工具在日常临床中使用最为广泛。2007年，VHI被改编用于歌唱人群，称为“适用于歌手的VHI”。我们研究的目的是调查适用于歌唱嗓音的德语版VHI的信度和效度。
113名具有不同演唱风格和职业的德国歌手（41名男性和72名女性）纳入本研究。他们被分为两组：有自我感知嗓音问题的测试组（n = 20）和无嗓音问题的对照组（n = 93）。分别采用克朗巴哈系数（即Cron.α）、独立t检验和受试者工作特征曲线以及似然比进行测量信度和效度的统计分析。
各分量表和总分的Cron.α（0.713 - 0.850）可接受，证实了信度。两组之间各分量表和总分的效度显示出高度显著差异，测试组得分高于对照组。只有结构效度未得出明确结果。
适用于歌唱嗓音的VHI适合作为可靠且有效的标准化评估工具，但由于目前数据结果解释的不准确性过高，诊断准确性必须再次进行研究。
