The Singing Voice Handicap Index (SVHI) was culturally adapted and validated in Greek to examine the impacts of voice problems on a singer's everyday life.
The translated version was administered to 120 singers in total, along with the translated version of the Voice Handicap Index (VHI), a sort voice history questionnaire, two Self-Rating Dysphonia Severity Scales (SRDSSs), and two visual analog scales. A week after the original completion of the Greek version of SVHI, a second copy of the SVHI was administered to 50% of the participants.
The results showed high test-retest reliability (Pearson correlation coefficient (PCC): 0.859, P = 0.000) and excellent internal consistency (Cronbach's Alpha = 0.960). A significant difference between healthy and voice disordered singers emerged (18.01 ± 13.213, 43.26 ± 20.196; K-W: P = 0.000; ROC: Area = 0.863, Std. = 0.041, P = 0.000). Also, high concurrent (Spearman's rho 0.55, P = 0.000) and face (Spearman's rho: SRDSS 0.481, P = 0.000; SRDSS 0.504, P = 0.000) validity scores were observed. Regarding the relation of the demographic variables or habits that could relate to voice disorders, only the years of experience (PCC: -0.240, P = 0.008) and singing lessons (Spearman's rho: -0.286, P = 0.002) had a strong correlation with SVHI.
In conclusion, the Greek version of the SVHI questionnaire was validated successfully as a reliable tool with proper internal consistency. It will serve as a suitable and valuable instrument for self-evaluation of a vocal difficulty's effects on a singer's day-to-day life.
对歌唱嗓音障碍指数（SVHI）进行希腊语文化适应性调整和验证，以研究嗓音问题对歌手日常生活的影响。
将翻译后的版本分发给总共120名歌手，同时发放嗓音障碍指数（VHI）的翻译版本、一份简短的嗓音病史问卷、两个自评嗓音障碍严重程度量表（SRDSS）以及两个视觉模拟量表。在最初完成希腊语版SVHI一周后，向50%的参与者发放第二份SVHI。
结果显示重测信度高（皮尔逊相关系数（PCC）：0.859，P = 0.000）且内部一致性极佳（克朗巴哈系数 = 0.960）。健康歌手和嗓音障碍歌手之间出现显著差异（18.01 ± 13.213，43.26 ± 20.196；K-W：P = 0.000；ROC：面积 = 0.863，标准差 = 0.041，P = 0.000）。此外，观察到较高的同时效度（斯皮尔曼等级相关系数0.55，P = 0.000）和表面效度（斯皮尔曼等级相关系数：SRDSS 0.481，P = 0.000；SRDSS 0.504，P = 0.000）得分。关于可能与嗓音障碍相关的人口统计学变量或习惯的关系，只有经验年限（PCC：-0.240，P = 0.008）和声乐课程（斯皮尔曼等级相关系数：-0.286，P = 0.002）与SVHI有强相关性。
总之，希腊语版SVHI问卷作为一种具有适当内部一致性的可靠工具已成功验证。它将成为评估嗓音困难对歌手日常生活影响的合适且有价值的自我评估工具。
