The Updated Illinois Rape Myth Acceptance Scale (UIRMAS) has been widely used for measuring rape myth acceptance. The scale was created in the United States, however studies have shown that rape myth is a culturally and socially embedded phenomenon. Therefore, in order to measure rape myth acceptance in other parts of the world, the scale needs to be validated. Victim blaming and rape myths are both widespread in public reactions to rape in Hungary (i.e., in media reports and public opinion). Furthermore, Hungary can be characterized by a weak feminist movement and scoring low on gender equality measures. Nevertheless, we expected and found the reliability and validity of the Hungarian version of the Updated Illinois Rape myth acceptance Scale (UIRMAS). In Study 1 we conducted a confirmative factor analysis to assess the structural validity of the scale and identified the original factors of UIRMAS on a large convenience sample (N = 758, 25.4% men 74.6% women). In line with previous empirical evidence we also found that men, people with stronger just-world beliefs and higher sexism accepted rape myths more. In Study 2 we again found support for the original factor structure and construct validity of UIRMAS on a nationally representative sample (N = 1007, 49.2% men 50.8% women), and also tested its convergent and discriminant validity. The results suggest that UIRMAS is a valid and reliable scale in the Hungarian context that can, for example, be used for measuring impact assessment of interventions.
