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.

摘要 少数群体应激（Minority Stress, MS）模型提出，存在特定应激源使女同性恋、男同性恋与双性恋群体（LGB）面临更高的社会脆弱性。该模型由内化性恐同（internalized homonegativity）、性取向隐瞒（concealment of sexuality）与污名经历（stigma experiences）三个维度构成。尽管该模型已获得实证支持，但目前尚无适配巴西语境的该模型评估工具。因此，本研究旨在针对巴西语境对LGB群体少数应激评估方案（PEM-LGB-BR）进行跨文化适配，并验证其效度证据。本研究的样本包含1451名被试，所有被试均完成了内化性恐同量表（Internalized Homonegativity Scale）、出柜量表（Outness Inventory）及污名经历量表（Stigma Experience Scale）的作答。探索性因素分析与验证性因素分析结果显示，PEM-LGB-BR的三因素结构为最优适配模型。该结果与理论预期相符，表明此评估方案可在巴西语境下有效应用。
