Abstract
Background: The validated Transsexual Voice Questionnaire Male to Female (TVQMtF) and the adapted TVQ Female to Male (FtM) (TVQFtM) are both 30-item-long questionnaires used to evaluate self-perception of voice in transgender persons. They are part of a series of questionnaires completed by transgender persons during follow-up of cross-sex hormone therapy (CSHT). Aim: The aim of this study was to examine if these questionnaires can be organized. Methods: The TVQMtF or the TVQFtM was filled out at the start of CSHT, by 145 trans women and 83 trans men. Data were analyzed by factor analyses on both the questionnaires. Results: The factor analyses resulted in a three-factor solution for both the TVQMtF and the TVQFtM. The three factors were labeled as anxiety and avoidance, vocal identity, and vocal function. Conclusion: Both the questionnaires can be organized into three factors. This could contribute to making shorter versions of the questionnaires. Shorter versions would be useful to hormone prescribing physicians to track down more quickly voice problems in trans people undergoing virilizing or feminizing hormone treatment.
