Primary use / Purpose:
The AMMSA is a measure of rape myth acceptance (RMA)
Although the construct was introduced during the era of second wave feminism, it was not until 1980 that Martha Burt published the first social scientific examination of rape myth acceptance.This scale design began with the standard definition that rape myths are ‘descriptive or prescriptive beliefs about rape … that serve to deny, downplay or justify sexual violence that men commit against women’ In rape myth methodology prior to the Acceptance of Modern Myths about Sexual Aggression (AMMSA), a minimum stipulation was that rape myths needed to be demonstrably false. Significantly however, the AMMSA and others move away from this: for their purposes, ‘it would be more expedient to define rape myths not as false, but rather as “wrong” in an ethical sense.’
The 30 item self-report scale AMMSA incorporates insights from racism and sexism research and measures the acceptance of modern myths about sexual aggression. Across four studies (total N=1,279), the reliability and validity of parallel German and English versions of the AMMSA scale were examined. The results show that both language versions are highly reliable; compared with a traditional RMA scale, means of AMMSA scores are higher and their distributions more closely approximate normality. Cross-sectional and longitudinal analyses provide evidence for the AMMSA scale’s concurrent and predictive construct validity.
