The effects of a bystander education intervention program on the factor structure underlying a rape myth acceptance scale were examined using exploratory factor analyses on secondary data. The Illinois Rape Myth Acceptance Scale was administered to college students at a northwestern university both before (n = 363) and after (n = 352) receiving a bystander education program. Results from exploratory factor analyses showed changes in the factor structure from pretest to posttest. This suggests some instability in the factor structure of the Illinois Rape Myth Acceptance Scale. These pre–post intervention differences in the rape myth acceptance factor structure suggest researchers use caution in using and interpreting scores based on the IRMA without regard to participants’ prevention program status.
