This study examined freshman college students' attitudes about date rape and how such attitudes changed over the course of their college experience. It is based on a subset of data from the 1990 annual national survey of freshmen and a follow-up study in 1994 collected by the Cooperative Institutional Research Program (CIRP) survey, namely 10,155 students attending 76 colleges and universities, as well as data from previous CIRP surveys. The study found that 87 percent of incoming students in 1989 reported being intolerant of date rape, while 90 percent of incoming students in 1994 reported being intolerant of date rape. It also found that while 75 percent of incoming students in 1990 reported being strongly intolerant of date rape, 84 percent of fourth-year students in 1994 reported being strongly intolerant of date rape. Female students were found to be more intolerant of date rape than male students, while Native-American freshmen were most strongly intolerant of date rape, followed in descending order by Puerto Ricans, Caucasians, Asian-Americans, Chicano/a, and African-American freshmen. Other racial, religious, political, and institutional influences on attitudes about date rape are also considered. (Contains 48 references.) (MDM)
