ObjectiveThe aim of this study was to create and validate an abbreviated version of the Spanish Transsexual Voice Questionnaire for Male-to-Female Transsexuals (SvTVQ
MtF).
SettingThe study was conducted by two referral hospitals for voice feminization surgery and by a university department of psychology and speech therapy, all in Spain.
Subjects and methodsWe prospectively studied 51 male-to-female transsexuals who underwent voice feminization surgery between January 2017 and December 2018. The SvTVQ
MtF was completed before and after surgery, and the 10 items with the greatest variation were selected by clinical consensus of an expert panel to develop the short version of the SvTVQ
MtF (SvTVQ
MtF-10). The correlation between the total score and the score for each item on the SvTVQ
MtF and the SvTVQMtF-10 was studied. The internal consistency of the SvTVQ
MtF-10 was analysed.
ResultsGood correlation (Pearson coefficient above .90) was found between the two questionnaires. A significant correlation was found between the total SvTVQ
MtF-10 score and the score for each item. A significant negative correlation was found between the SvTVQ
MtF and fundamental frequency after voice feminization surgery. Cronbach's α was .79.
ConclusionThe SvTVQ
MtF-10 is a valid short version of the SvTVQ
MtF and can be used to quantify voice-related quality of life in MtF transsexuals.
