The authors have identified this gap as a major problem because the risk of sexual assault of American women studying abroad is 3 to 5 times greater than that of their peers who remain in the States. The research that has been done has not identified if the perpetrators are citizens in the countries the women are visiting or are other students studying abroad--so there is a gap in the research as well.
The authors outline the reasons for women to take a resistance training program (e.g. IMPACT) before studying abroad. For the details, check out pages 2 and 3 in the Winter 2018 issue of The Society for the Scientific Study of Sexuality.
