Protocol to Evaluate Stress of Minority in Lesbians, Gays and Bisexuals

Abstract The Minority Stress (MS) model proposes the existence of specific stressors that make lesbian, gay and bisexual people (LGB) more socially vulnerable. MS is composed of internalized homonegativity, concealment of sexuality, and stigma experiences. Although the model has received empirical support, there are no instruments adapted for its assessment in the Brazilian context. Therefore, this study aimed to cross-culturally adapt and assess validity evidences for the Brazilian context of a protocol for the assessment of MS in LGBs (PEM-LGB-BR). The sample consisted of 1451 participants who answered the Internalized Homonegativity Scale, the Outness Inventory, and the Stigma Experience Scale. Exploratory and confirmatory factor analyses suggest the three-factor structure of PEM-LGB-BR as the most adequate. This result is consistent with the theory, making the protocol valid for use in the Brazilian context.
