Abstract
Transphobia is an under-examined but important type of prejudice to study in Polish culture. Poland is a country where a majority of transgender people feel discriminated against. There is a need for a more evidence-based measures for researchers and practitioners to better understand transphobia. The main purpose of the present three studies (n = 300 participants for each study) was to validate the Genderism and Transphobia Scale (GTS; Hill and Willoughby 2005) and the Transphobia Scale (TS; Nagoshi et al. 2008) in Polish culture and to identify the possible psychological and demographic factors that matter in forming attitudes toward transgender individuals. The results confirm that Polish versions of both the GTS and the TS are reliable instruments to measure attitudes toward transgender individuals. Moreover, the studies revealed that both traditional and modern homonegativity, right-wing authoritarianism, social dominance orientation, religious fundamentalism, attitudes toward gender roles, and biological and cultural beliefs about the origins of gender differences were significant predictors of transphobia. As in previous studies, men were more prejudiced toward gender nonconformists in comparison to women. These studies contribute well-adapted tools for measuring transphobia and data-driven collection of significant predictors of transphobia.
