In the comparison group, there were 512 women who had never experienced unwanted sexual abuse and 187 women who had been affected by unwanted sexual activity. Additionally, for the purposes of this study, six categories of intrusive sexual conduct were detailed which included: unwanted oral sex, unwanted genital touching, penetration, vaginal penetration, sexual intercourse, or anal sex. These specific categories were used to interview women who had experienced sexual violence. The six categories were each organized into three variables which were "oral sex, genital touch and vaginal intercourse" (Rellini, Meston, 2007). The task entrusted to these women was to answer questions referring to the three variables. The way it worked was that if a woman reported at least one of the three variables, then she would get a score of “1” which was identified as a CSA survivor.
