Breaking the endometriosis silence: a social norm approach to reducing menstrual stigma and policy resistance among young adults

Abstract

Objective Endometriosis is a menstrual disorder that affects one in ten women. Diagnosis often takes several years due to low awareness and menstrual stigma. In this study, we employed a social norm approach (SNA) to investigate the effects of an educational leaflet on endometriosis knowledge, menstrual stigma, and acceptance of paid menstrual leave among women and men. Methods The 3 × 2 online experiment tested the influence of either descriptive norm messages or both descriptive and injunctive norm messages (compared to a control group, factor 1) in an educational leaflet by taking the role of addressee’s sex into account (quasi-experimental factor 2). The study included 796 German participants aged 16–35. Results Men exhibited significantly poorer knowledge, stronger menstrual stigma, and weaker policy acceptance compared to women. No significant main effect of the social norm messages on menstrual stigma was found. In contrast, the combined norm messages seem to be beneficial when addressing policy acceptance. Moreover, compared to the control group, the intervention material indirectly influenced stigma and policy acceptance through increased knowledge. Conclusions Providing information about social norms appears to be an effective strategy for educating not only women but especially men about menstrual disorders like endometriosis.
