Results showed that women who had studied abroad were four times as likely as women who had not studied abroad to have been victims or unwanted sexual contact. Women who studied abroad were found to be three times as likely to be victims of an attempted sexual assault and five times as likely to have been raped.
Essentially, it sounds like a confluence of factors related to living in a strange country make women more vulnerable to assault and less able to cope with or report it. Support networks can be vital in these situations.
