ABSTRACT Abortion Stigma (AS) is a negative attribute ascribed to women who terminate a pregnancy that marks her as inferior to the ideals of femininity. Based on traditional normative gender codes, religious groups are identified in the literature as the most relevant source of AS. To analyse the influence of religiosity on AS and the mediating effect of stereotyped gender attitudes, we carried out a multivariate causal quantitative study. With a community sample of 360 Chileans, we used structural equation modelling to determine that religiosity influences AS directly and indirectly through stereotyped gender attitudes. This model showed adequate fit indices and explained 69.2% of the variance. We tested a second structural equation model with a control variable, and we discuss these findings’ implications for Chilean society, where religion occupies a significant place in power and decision-making centres. We propose gender equity education as a strategy to reduce AS.
