# \"Good Guys Don't Rape\": Greek and Non-Greek College Student Perpetrator Rape Myths
## 2 Methods
### Measures  
Controls: Previous victimization was hypothesized to influence participants' perceptions regarding sexual assault, making it a necessary control variable. We assessed sexual assault victimization via a modified version of the Modified Sexual Experiences Survey-Short Form Victimization (SES-R). The SES-R determines an individual's nonconsensual sexual experiences from those that occurred before and since the age of fourteen; the current study assessed victimization since the age of 14. The scale measures seven types of unwanted sexual experiences (including unwanted sexual touching, oral, vaginal and anal penetration) by five different methods the perpetrator may have used (i.e., verbal coercion, manipulation, taking advantage via alcohol/drugs, physical threatening and physical force) and aims to identify previous victimization while avoiding terms such as rape, due to vastly varied definitions from respondents [30]. Participants were coded into two categories based on their responses, victim and non-victim. There were 114 participants who reported rape victimization as experiencing completed nonconsensual oral, anal or vaginal penetration (13%; 109 women, 5 men). A majority of the victims were affiliated with Greek-life (\(n\) = 73; 64%). Rape myth acceptance was measured by the Illinois Rape Myth Acceptance Scale, which assesses a participants' support for rape myths or false beliefs about sexual assault and sexual assault victims [12]. Example items include: \"Rape happens when a man's sex drive gets out of control,\" \"Many women secretly desire to be raped,\" \"If a guy is drunk, he might rape someone unintentionally\" and \"A rape probably didn't happen if the girl has no bruises or marks.\" The scale ranged from 1 = strongly disagree to 7 = strongly agree (\(M\) = 2.36, \(SD\) = 1.03, alpha = 0.94) and was used in order to assess the convergent validity of the perpetrator rape myth measure. Perpetrator rape myths were measured by items specifically written for the current study. These items were written to understand ways in which people view perpetrators better, in terms of stereotypical rape scenarios. Guided by previous research [12; 31; 32; 33], 20 items were written to assess the characteristics and stereotypes of those who perpetrate sexual assault; see Table 1 for all items. The 20-item measure ranged from 1 = strongly disagree to 7 = strongly agree (\(M\) = 2.08, \(SD\)= 1.00, alpha = 0.94). In order to assess the convergent validity of perpetrator rape myths, we examined the association with rape myth acceptance. Perpetrator rape myths were positively and strongly correlated with the rape myth acceptance scale (\(r\) = 0.64, \(p\) < 0.001). Students who reported higher rape myth attitudes also perceived perpetrators as more stereotypical. \begin{table}
