This scoping review investigates the existing literature regarding personality traits, ideology, gender roles, and attitudes toward LGBT people. The review was conducted through PubMed and Web of Science databases. After establishing inclusion- and exclusion criteria, 12 studies published between 2013 and 2023 were reviewed, three themes (personality traits, gender roles and differences, and political ideology) were identified through thematic analysis. Several of the studies reported a relation between the personality traits Openness to Experience, Agreeableness and Conscientiousness, and homo- and transnegative attitudes. In particular, lower levels of Agreeableness, high levels of Conscientiousness, and lower levels of Extraversion were related to prejudice. The Dark Triad, especially the antagonistic traits Psychopathy and Machiavellianism, had a strong association with homo- and transnegativity. Multiple studies showed a connection between negative attitudes and ideological views. Especially right-wing authoritarianism (RWA) and social dominance orientation (SDO) were strong predictors of negative attitudes toward LGBT people. The majority of the studies also reported a significant gender difference in attitudes, with men being more prone to exhibit prejudice toward LGBT people than women. There are practical implications of this review relating to interventions which may target the prevention of homo and trans-negative attitudes, promoting inclusion and integration.
