Multidimensional Scale of Sexual Prejudice: Psychometric Properties for the Brazilian Context

Abstract

This paper aimed to adapt the Multidimensional Scale of Sexual Prejudice (MSSP) to the Brazilian context, gathering evidence of its psychometric adequacy. Two studies were conducted. Study 1 participants were 223 undergraduate students (Mage = 22.5; 62.8% women), who answered the MSSP and demographic questions. Principal components analysis indicated a five-factor structure [Heterosexist (α = 0.97), Aversion to homosexuals (α = 0.94), Positive beliefs towards homosexuals (α = 0.89), Resistance to heteronormative (α = 0.91), and Denial of discrimination (α = 0.49)]. Study 2 considered 261 people from the general population (Mage = 30.0; 61.7% women), who answered the same instruments of the previous study. A confirmatory factor analysis, considering item parcels, corroborated the five-factor structure (e.g., AGFI = 0.93, and RMSEA = 0.05). In conclusion, the MSSP is a psychometrically adequate measure, and thus it can be used in future studies aiming to know the sexual prejudice and its correlates.
