Validation Study of the Revised Version of the Scale of Prejudice against Sexual and Gender Diversity in Brazil.

In Brazil, there is a deficit of culturally adapted tools to assess prejudice against sexual and gender diversity with empirically demonstrable validity and reliability. Prejudice against non-heterosexual orientations is a strong problem within Brazilian culture and is particularly related to non-normative expressions of gender. To address these issues, a scale was created. The objective of this article is to validate the revised version of this instrument developed for the specificities of Brazilian culture and establish its reliability. Eight thousand, one hundred and eighty-four undergraduate students from southern Brazil completed the revised version of Scale of Prejudice Against Sexual and Gender Diversity (PASGD). Analysis was conducted using Item Response Theory (IRT) model for rating scale data, criterion validity and confirmatory factor analysis (CFA). The scale showed good validity and reliability. The results indicate that the PASGD is a useful tool for assessing prejudice in the Brazilian context, adapted for the local Brazilian reality.
