First multi-country study of rape and partner violence... - full text

In reading the study itself, this paragraph got to the core of the problem (ACEs):

Men who had ever been married or cohabited were more likely to have engaged in single perpetrator non-partner rape than were those who had not been married, and men who were poor (indicated by present food insecurity), or had no high school education (compared with any high school or higher education) were more likely to have raped with multiple perpetrators. Men with a history of victimisation, especially child sexual abuse and having been raped or otherwise sexually coerced themselves, were more likely than were those without such a past to have perpetrated either type of rape. Exposure to childhood physical abuse was associated with a greater likelihood of single perpetrator rape, and a history of experience of homophobic violence with multiple perpetrator rape. Emotional abuse and neglect were associated with both types of rape, as were heavy alcohol consumption and low levels of empathy.To have been physically violent toward a partner, to have ever had sex with a sex worker or engaged in transactional sex, and to have had more lifetime sexual partners were associated with both types of rape—the latter association strengthened with increasing numbers of lifetime partners. Involvement in fights with weapons was associated with both types of rape, and multiple perpetrator rape was associated with gang memberships and drug use within the past year. 

One of the tables (Table 4) showed that not having a father in the home was even more significant than experiencing childhood sexual abuse, but not more than experiencing emotional or physical abuse.

I'd love to see a list of the questions (not all are included, especially the questions about ACEs), and whether the researchers know about the ACE Study. Finding out the ACE score of the 10,000+ men they interviewed might be more revealing than the reasons why they raped. It would point to the roots of the issue, and perhaps provide guidance for prevention measures.
