Illinois Rape Myth Acceptance (IRMA) Scale

The Illinois Rape Myth Acceptance (IRMA) Scale contains 45-items that asks respondents to rate their level of agreement when considering statements about women and sexual assault. Items were categorized into the following seven subscales: she asked for it (SA), it wasn't really rape (NR), he didn't mean to (MT), she wanted it (WI), she lied (LI), rape is a trivial event (TE), and rape is a deviant event (DE). A short form of the IRMA scale has also been developed and can be viewed here.

17. (NR-5) A rape probably didn’t happen if the woman has no bruises or marks
18. (WI-4) Many women find being forced to have sex very arousing
19. (SA-4) If a woman goes home with a man she doesn’t know, it is her own fault if she is raped
20. (MT-5) Rapists are usually sexually frustrated individuals

22. (DE-3) It is usually only women who dress suggestively that are raped
23. (WI-2) Some women prefer to have sex forced on them so they don’t have to feel guilty about it
24. (NR-3) If the rapist doesn’t have a weapon, you really can’t call it a rape
25. (SA-6) When a woman is a sexual tease, eventually she is going to get into trouble

35. (DE-6) Rape almost never happens in the woman’s own home
36. (SA-5) A woman who ‘‘teases’’ men deserves anything that might happen
37. (SA-8) When women are raped, it’s often because the way they said ‘‘no’’ was ambiguous
38. (TE-4) If a woman isn’t a virgin, then it shouldn’t be a big deal if her date forces her to have sex
39. (MT-1)Men don’t usually intend to force sex on a woman, but sometimes they get too sexually carried away

45. (NR-4) If a woman claims to have been raped but has no bruises or scrapes, she probably shouldn’t be taken too seriously

*FI=Filler Item. These ‘‘filler items’’ are included to minimize the potential for response bias and are therefore discarded before conducting any statistical analysis. They do not contribute to the total scale value.

Response options:
Respondents were asked to rate their level of agreement using a 7-point Likert scale ranging from 1 = "not at all agree" to 7 = "very much agree.”
Scores to the Filler Items are not counted towards to total scale value.
