Objective. The purpose of this study was to examine the psychometric properties of the German translation of the Transsexual Voice Questionnaire for Male-to-Female Transsexuals (TVQMtF), an instrument assessing the voice-related quality of life (VrQoL) in trans women.
Study Design. This is a cross-sectional study.
Method. The conducted online survey contained the TVQMtF as well as a generic measurement of VrQoL (Voice Handicap Index) and items on transition. Data of 127 trans women were analyzed computing coefficients of reliability and convergent validity. Additionally, confirmatory factor analysis and model modification were performed.
Results. Analyses revealed excellent internal consistency (α = 0.97), split-half reliability (rSB = 0.95) and good convergent validity. Significant associations were found between the total scores of the German TVQMtF and the Voice Handicap Index (r = 0.88; P < 0.001) as well as the vocal self-perception (r = ¡0.57; P < 0.001). An acceptable model with a two-factor structure including 22 of the 30 items was found.
Conclusions. The TVQMtF is the first German reliable and valid measurement of VrQoL for trans women. Therefore, its utilization can be recommended for clinical and research purposes in the fields of voice therapy and surgery.
