Voice-related Experiences of Nonbinary Individuals (VENI) Development and Content Validity.

Transgender individuals may seek a variety of gender-affirming health and educational services, including voice modification from speech-language pathologists. Measuring the client's self-perception of their communication experiences is crucial for providing client-centered services and measuring outcomes. However, there is currently no validated assessment tool for the nonbinary population, a part of the transgender population. This study explores the voice-related concerns and experiences among the nonbinary population to create a valid measure of their self-perception of voice. Ten nonbinary individuals were surveyed about their voice-related concerns and experiences. A thematic analysis of the responses led to the development of the questionnaire, titled the Voice-related Experiences of Nonbinary Individuals. The questionnaire was systematically evaluated for its content validity by a panel of speech-language pathologist experts in transgender voice services. Outcomes of this analysis supported the measure's content validity and motivated further revisions. This is the first assessment tool that measures self-perception of voice and voice-related experiences for nonbinary individuals. Initial psychometric testing supported its content validity and further research is needed for large-scale testing of validity and reliability.
