Even though menstruation is a normal physiological process in a female reproductive cycle and an indicator of overall health, it's surrounded by taboo, stigma, shame, concealment, and misunderstanding. Methodological goal of this thesis was to translate and adapt BATM scale (Beliefs and Attitudes toward Menstruation) on a sample of students at University of Zagreb. Empirical goal was to determine how beliefs and attitudes toward menstruation differ considering their individual characteristics, sexist tendencies, and the level of knowledge about menstruation. The research was carried out on a convenience sample of 1975 university students at the University of Zagreb. The results offer an insight into students’ beliefs and attitudes about menstruation demonstrating that, on average, male students are more prone to beliefs and attitudes that emphasise the importance of concealing menstruation and following certain proscriptions and prescriptions while menstruating. Furthermore, we can also conclude that students’ beliefs and attitudes towards menstruation are mostly determined by sexist tendencies. Thus, sexism proved itself to be an important factor in determining beliefs and attitudes related to secrecy, proscriptions and prescriptions and menstruation as a disability, where higher sexist tendencies were related with more negative attitudes towards menstruation. It was not possible to make concrete conclusions regarding understanding menstruation through the concept of pleasure. This insinuates that this aspect of attitudes towards menstruation requires further modifications in order to better measure positive aspects of menstruation. In conclusion, this thesis contributed to a more comprehensive understanding of menstruation in contemporary Croatian society which further supplements theoretical, methodological and empirical knowledge about this topic.
