The Singing Voice Handicap Index (SVHI) was developed in the United States for the self-assessment of patients with singing problems. It has been translated into German and its reliability and validity have been assessed. In total, 54 (35 female, 19 male) dysphonic singers and 130 (74 female, 56 male) non-dysphonic professional singers were included in the study. Reliability rested on high test-retest reliability (r = 0.960, p ≤ 0.001, Pearson correlation) and a Cronbach's α of 0.975. A principal component analysis using the Varimax method and the results of the screeplot suggest the SVHI scored as a single scale. Validity rested on a highly significant correlation between the severity of the self-rated voice impairment by the patient and the total SVHI score. Dysphonic singers have significantly higher SVHI scores than healthy singers. The SVHI is thus suited to implementation as a diagnostic tool in German-speaking countries.
歌唱嗓音障碍指数（SVHI）是在美国开发的，用于对有歌唱问题的患者进行自我评估。它已被翻译成德语，并对其信度和效度进行了评估。该研究共纳入了54名（35名女性，19名男性）发声障碍歌手和130名（74名女性，56名男性）无发声障碍的专业歌手。信度基于高重测信度（r = 0.960，p≤0.001，Pearson相关性）和Cronbach's α为0.975。使用Varimax方法进行的主成分分析和碎石图结果表明，SVHI作为单一量表进行评分。效度基于患者自我评定的嗓音障碍严重程度与SVHI总分之间的高度显著相关性。发声障碍歌手的SVHI得分显著高于健康歌手。因此，SVHI适合在德语国家作为一种诊断工具使用。
