Abstract
Objectives: The aim of this study was to adapt and apply the Portuguese versionof the Transgender Man Voice Questionnaire in a sample of Brazilian transgendermen and to investigate the relationship between voice satisfaction and hormonetherapy duration. In addition, we suggest reducing and reformulating thequestionnaire for screening.
Methods: We conducted a cross-sectional study of 31 transgender men aged 18–50 years undergoing hormone therapy who answered a questionnaire adaptedfrom the Transgender Woman Voice Questionnaire, validated in Portuguese.Sociodemographic and clinical data were collected from the individuals’electronic medical records: age, smoking status, and type and duration ofhormone therapy. The questionnaire, consisting of 30 questions rated on aLikert scale, was answered individually during a psychotherapy session. In eachquestion, the gender-specific words were modified. Furthermore, we added aquestion: 31 (After GAHT, my voice became completely male), with the responseoptions yes or no. In questions 32 and 33, asking participants to provide anoverall rating of their voice. Total score ranged from 0 to 120, with higher scoresindicating greater dissatisfaction with voice.
Results: Mean patient age was 30.13 ± 7.6 years, and 19.4% were smokers. Themean duration of hormone therapy was 29.7 ± 24.9 months, and 95% receivedintramuscular testosterone cypionate, maintaining serum testosterone levelswithin the male reference range. The questionnaire mean total score was 51 ± 17.72.There was a significant negative correlation between the questionnaire total scoreand duration of hormone therapy (r = −0.484, p = 0.006). The questionnaire hada high level of internal consistency/reliability, with a Cronbach’s alpha coefficientof 0.95 for all items and a split-half Spearman-Brown coefficient of 0.96. For theelaboration of a screening tool, it is suggested to remove questions 8, 10, 12, 13,14, 17, 19, 23, 27, and 29 and modify question 1.
Conclusion: Longer hormone therapy favors voice deepening and satisfactionwith voice. The psychometric properties of the Transgender Man VoiceQuestionnaire are reliable, supporting its use as a screening tool in clinicalpractice and as an adjunct to the planning of vocal and communication supportfor transgender individuals.
