[The construction behind chosen names of transgender individuals and related aspects in a medium-sized city in the South of Brazil].

This study analyzed the construction process of the chosen name and related aspects among transgender individuals from a medium-sized municipality in southern Brazil. Qualitative data from a descriptive and exploratory mixed-method study was used. Self-declared trans people aged 18 or over were included. Three focus groups were conducted with ten participants. These individuals, aged between 19 and 52 years, have a documented chosen name, but half have not yet changed their civil records. The content analysis technique produced two categories: "construction of the chosen name as an instrument for validating the transgender identity" and "impacts of the construction of the chosen name on self-acceptance and on family and social relationships." The results reinforce the importance of respecting the name as a way of contributing to the gender affirmation of transgender individuals. The name was linked to the experiences, individuality and values of these individuals. Its proper use, much more than respect for legislation, meant respect for the different possibilities of human existence. It is expected that the results presented can be used as a tool for recognizing the issues and nuances that permeate the construction of the chosen name and contribute to identity validation.
