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 (TVQ ) 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 TVQ (TVQ -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 TVQ -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 TVQ -TR again two weeks after the first interview.

RESULTS

The total Cronbach's-α value of the TVQ -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 TVQ -TR and self-perceptions of voice femininity. There was a significant negative correlation between TVQ -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 TVQ -TR was considered a valid and reliable tool.
