The Beliefs about Children's Adjustment in Same-Sex Families Scale (BCASSFS) is an instrument that measures rejection of the child-rearing and educational practices of same-sex parents. This scale evaluates beliefs that are organized in a bifactorial model referring to Individual Opposition and Normative Opposition. This study aimed to adapt the BCASSFS and examine its validity in the Brazilian context with a sexually diverse sample. A national survey was carried out with a sample of 1038 participants. It was used a sociodemographic questionnaire; a version of the BCASSFS adapted for the Brazilian context; a measure of sexual prejudice; and a measure of conservatism. Confirmatory factor analysis showed good fit indices for the model suggested for the original scale. Multigroup confirmatory factor analysis showed that the BCASSFS displayed measurement invariance between subsamples of different profiles, such as heterosexual-cisgender and LGBT + participants. Investigations of concurrent, convergent and criterion validity also showed that both scale factors were associated with theoretically related variables, in line with the literature. Together, these results show that the BCASSFS has good validity and can be used in the Brazilian context. By confirming the replication of the original model, this study contributes to broadening knowledge about these dimensions of sexual prejudice.
