Adaptação Transcultural da Transgender-specific intimate partner violence scale (T-IPV) para uso no Brasil

Abstract

The Transgender-specific intimate partner violence scale (T-IPV) was developed in 2019 to assess intimate partner violence in transgender people and initially consisted of four items. In 2021, based on empirical evidence that indicated a reduced number of items to represent the constructs of interest, the scale became 10 items, and after the psychometrics stage it was refined to an eight-item scale. The aim of this dissertation is to carry out the first (prototypical) phase of cross-cultural adaptation of the Transgender-specific intimate partner violence scale (T-IPV) into Brazilian Portuguese. This is a cross-cultural adaptation study involving the first phase and five stages: theoretical (conceptual), item content, semantic, operational and pretest equivalences. The pretest was conducted by the Research Center on Human Rights and Health of the LGBT+ Population (NUDHES) and took place in the state of São Paulo. The sample size was defined taking into account the availability of participants, and should not be less than 15. The results of the study show that all the equivalences - conceptual, semantic, operational, item and measurement - were achieved, but some adjustments were necessary to align the instrument with the cultural specificities of the trans and transvestite population in Brazil. The first phase of the CTA process for the T-IPV instrument was successfully completed. This initial stage qualifies the project to move on to the subsequent, psychometric phase, to assess whether the instrument is good in the Brazilian context
