In a survey of New Zealand undergraduate university students, 51.6% of 347 women revealed that they had experienced some form of sexual victimization (using the Sexual Experiences Survey; Koss & Oros, 1982), and 25.3% had either been raped or experienced attempted rape. These prevalence data are almost identical to those found using the same instrument with a national sample of U.S. university student women (Koss, Gidycz, & Wisniewski, 1987). The men in the New Zealand sample, however, reported perpetrating considerably less sexual aggression than their American counterparts. Most of the sexual victimization reported by women occurred within heterosexual relationships.
