Attitudes of a random sample of students at a large university toward foreign students and international programs were surveyed before and after the seizure of U.S. hostages in Iran. A newly developed "International Issues Questionnaire" covered attitudes toward foreign students as teaching assistants, funding exchange programs with student fees, and attitudes regarding international relations issues. Students were asked about their contact with foreign students, their experiences with other cultures, and their demographic characteristics. In the spring of 1979, 743 students responded to the mail questionnaire, and six months later, 404 students responded to the followup survey. In contrast to a majority view of the value and desirability of interaction with foreign students, less than one-third of respondents on both surveys agreed that there was meaningful contact between U.S. students and foreign students at the university. Most students did not change their attitudes toward foreign students after the takeover of the U.S. embassy in Iran, but their responses did show increased support for funding international exchange programs. Attitudes toward foreign students were significantly related to respondents' demographic characteristics, political views, and the frequency and form of their contact with foreign students. More positive attitudes toward foreign students were associated with being female, older, enrolled in graduate school, living off campus, and having travelled abroad. The more frequent the students' reported contact with foreign students, the more positive were their attitudes. A bibliography and questionnaire are appended. (SW)
