The purpose of this article is to translate and adapt the Trans Woman Voice Questionnaire (TWVQ) into the simplified Chinese version (TWVQ-SC), and to evaluate its reliability and validity. Authorized by the author of the TWVQ,the TWVQ-SC was developed through translation, back translation,and cross-cultural adaptation.The TWVQ-SC contained 30 items capturing personal perception of vocal function, psychosocial impact of voice, and degree of limitation in social participation. Subjects included 279 trans women in the experimental group, 128 cis women in the control group, and 89 trans women in the retest group. The Cronbach α and the item total correlation coefficient (ITC) were calculated to examine the internal consistency. The intraclass correlation coefficient (ICC) was chosen to examine the test-retest reliability. Regarding validity, the expert judgment method was utilized to examine the content validity. Factor analysis and Spearman's rank correlation coefficient were used to examine the construct validity, and the discriminant validity was examined by the rank sum test of the total scores of the cisgender and transgender subjects. The Cronbach's α of TWVQ-SC is 0.97 and the ITC of 30 items range from 0.40 to 0.86. The ICC is 0.84. The four principal components' cumulative contribution is 65.12%. The Spearman rank correlation coefficient to VHI-10 is 0.85 (<0.01). The total score of the TWVQ scale in the transgender female group is significantly higher than that in the cisgender female group (=1 580,<0.01). TWVQ-SC demonstrates good reliability and validity and therefore can be used clinically as a self-assessment tool for transgender women to evaluate their own voice.
本文旨在将跨性别女性嗓音问卷（TWVQ）翻译并改编为简体中文版（TWVQ-SC），并评估其信效度。经TWVQ作者授权，TWVQ-SC通过翻译、回译和跨文化调适而制定。TWVQ-SC包含30个项目，涵盖个人对嗓音功能的感知、嗓音的心理社会影响以及社会参与受限程度。受试者包括实验组的279名跨性别女性、对照组的128名顺性别女性以及重测组的89名跨性别女性。计算Cronbach α系数和项目总分相关系数（ITC）以检验内部一致性。选择组内相关系数（ICC）来检验重测信度。关于效度，采用专家判断法检验内容效度。使用因子分析和Spearman等级相关系数检验结构效度，并通过顺性别和跨性别受试者总分的秩和检验来检验区分效度。TWVQ-SC的Cronbach's α系数为0.97，30个项目的ITC范围为0.40至0.86。ICC为0.84。四个主成分的累积贡献率为65.12%。与VHI-10的Spearman等级相关系数为0.85（<0.01）。跨性别女性组的TWVQ量表总分显著高于顺性别女性组（=1 580，<0.01）。TWVQ-SC具有良好的信效度，因此可在临床上用作跨性别女性评估自身嗓音的自我评估工具。
