Objective: To perform a cross-cultural adaptation into Italian and to analyse reliability and validity of the Transsexual Voice Questionnaire for male-to-female transsexuals (I-TVQMtF). Study Design: Cross-sectional nonrandomized survey study. Methods: For item-generation, a cross-cultural adaptation and translation process was performed following standard guidelines. Transgender women were consecutively recruited and asked to fill out the I-TVQMtF and a form on social, demographic and transition-related variables. Firstly, data collected from participants were used to perform confirmatory factor analysis, and to evaluate internal consistency and test-retest reliability Subsequently, convergent validity was evaluated comparing I-TVQMtF total scores with the two extra items addressing self-perception (SPVF) and aspiration (AVF) of voice femininity. To evaluate convergent validity, scores of the Italian version of the Voice Handicap Index were considered for comparisons. A correlation analysis was performed to verify potential association between I-TVQMtF scores and social, demographic and transition-related variables. Results: Confirmatory factor analysis demonstrated that a two-factor model fits data better than the unidimensional one. Both internal consistency and test retest reliability of the I-TVQMtF were satisfactory. Negative correlations were highlighted between I-TVQMtF scores on one side and self-perception vocal functioning and aspiration vocal functioning on the other. Positive correlations between I-TVQMtF and Italian version of the Voice Handicap Index scores were also found. Finally, negative correlations were demonstrated between I-TVQMtF scores and time spent living in the female role. Conclusion: The I-TVQMtF appears to be a reliable and valid instrument for the assessment of voice-related quality of life in transgender women.

Abstract

Objective: To perform a cross-cultural adaptation into Italian and to analyse reliability and validity of the Transsexual Voice Questionnaire for male-to-female transsexuals (I-TVQMtF). Study Design: Cross-sectional nonrandomized survey study. Methods: For item-generation, a cross-cultural adaptation and translation process was performed following standard guidelines. Transgender women were consecutively recruited and asked to fill out the I-TVQMtF and a form on social, demographic and transition-related variables. Firstly, data collected from participants were used to perform confirmatory factor analysis, and to evaluate internal consistency and test-retest reliability Subsequently, convergent validity was evaluated comparing I-TVQMtF total scores with the two extra items addressing self-perception (SPVF) and aspiration (AVF) of voice femininity. To evaluate convergent validity, scores of the Italian version of the Voice Handicap Index were considered for comparisons. A correlation analysis was performed to verify potential association between I-TVQMtF scores and social, demographic and transition-related variables. Results: Confirmatory factor analysis demonstrated that a two-factor model fits data better than the unidimensional one. Both internal consistency and test retest reliability of the I-TVQMtF were satisfactory. Negative correlations were highlighted between I-TVQMtF scores on one side and self-perception vocal functioning and aspiration vocal functioning on the other. Positive correlations between I-TVQMtF and Italian version of the Voice Handicap Index scores were also found. Finally, negative correlations were demonstrated between I-TVQMtF scores and time spent living in the female role. Conclusion: The I-TVQMtF appears to be a reliable and valid instrument for the assessment of voice-related quality of life in transgender women.
