Investigating Validity and Reliability of the Turkish Version of Transsexual Voice Questionnaire (Male to Female)

Objective The problems faced by trans women with regard to their voice may affect their quality of life. For the evaluation of trans women's voice, tools assessing their self-perception are very important, with the Transsexual Voice Questionnaire (TVQMtF ) being one of the most frequently used. The purpose of this study was to investigate the validity and reliability of the Turkish version of the TVQMtF (TVQMtF –TR), which was previously translated into 12 languages. Study Design Cross-sectional study. Method A total of 41 trans women participated in this study. The participants filled out the TVQMtF -TR, the self-perceptions of voice femininity questionnaire, and the World Health Organization Quality of Life Questionnaire-Short Form (WHOQOL-BREF-TR). Additionally, 58.5% of the participants filled out the TVQMtF –TR again two weeks after the first interview. Results The total Cronbach's-α value of the TVQMtF –TR was 0.972, and the item-total correlation values were found to be between 0.323 and 0.876. The intraclass correlation coefficient value was 0.931. There was a strong negative correlation between TVQMtF –TR and self-perceptions of voice femininity. There was a significant negative correlation between TVQMtF –TR and the psychological and environmental domains of WHOQOL-BREF-TR. However, there was no significant relationship found between the social and physical domains. Conclusion According to the results of the study, the Turkish version of TVQMtF –TR was considered a valid and reliable tool.
