To evaluate the validity and reliability of the Turkish version of the Singing Voice Handicap Index-10 (SVHI-10).
Cross-sectional study.
Two hundred singers consisting of a control group (n = 136) without voice complaints and a study group (n = 64) diagnosed with a voice disorder served as participants. To detect test-retest reliability, 97 participants (representing a portion of both the control and study group participants) completed the index twice with a minimum of a one-week interval between each completion. Internal consistency was confirmed using Cronbach's alpha coefficient. To complete a clinical validity assessment, scores from the control group participants were compared with scores from the study group participants. To determine content validity, the correlation between the SVHI-10 and the participants' perceptions of singing voice complaints was researched. The sensitivity and specificity of the SVHI-10/Turkish version were calculated using a receiver operating characteristic curve analysis.
Cronbach's alpha coefficient, which was equal to 0.91, proved to have excellent internal consistency. Item-total correlations were found in the range of 0.55 to 0.76. The mean SVHI-10/Turkish score for the control group was 8.14 ± 5.4, whereas this value was significantly higher in the study group (20.54 ± 6.9, P < 0.001). The Pearson product-moment correlation test indicated that the Turkish SVHI-10 is a reliable tool (r = 0.90, n = 97, P < 0.001). The area under curve of the Turkish SVHI-10 was 0.95. The optimal cut-off point was found to be 11.5, with a sensitivity of 95.8% and a specificity of 83.2%.
The Turkish version of the SVHI-10 has proven to be a reliable and valid instrument for evaluating the self-perception of a singer in relation to voice problems. It can also be used as a quick screening tool because a score on the SVHI-10 higher than 11.5 is indicative of an abnormal singer's perceived voice handicap.
评估土耳其语版歌唱嗓音障碍指数-10（SVHI-10）的有效性和可靠性。
横断面研究。
200名歌手参与研究，其中包括一个无嗓音问题的对照组（n = 136）和一个被诊断为嗓音障碍的研究组（n = 64）。为检测重测信度，97名参与者（代表对照组和研究组参与者的一部分）完成该指数两次，每次完成之间至少间隔一周。使用克朗巴哈系数（Cronbach's alpha coefficient）确认内部一致性。为完成临床有效性评估，将对照组参与者的得分与研究组参与者的得分进行比较。为确定内容效度，研究了SVHI-10与参与者对歌唱嗓音问题认知之间（得分）的相关性。使用受试者工作特征曲线分析计算SVHI-10土耳其语版的敏感性和特异性。
克朗巴哈系数等于0.91，证明具有出色的内部一致性。项目与总分的相关性在0.55至0.76之间。对照组的SVHI-10土耳其语版平均得分为8.14±5.4，而研究组的该值显著更高（20.54±6.9，P<0.001）。皮尔逊积差相关检验表明土耳其语版SVHI-10是一个可靠的工具（r = 0.90，n = 97，P<0.001）。土耳其语版SVHI-10的曲线下面积为0.95。发现最佳截断点为11.5，敏感性为95.8%，特异性为83.2%。
SVHI-10土耳其语版已被证明是评估歌手对嗓音问题自我认知的可靠且有效的工具。它也可作为一种快速筛查工具，因为SVHI-10得分高于11.5表明歌手感知到的嗓音障碍异常。
