Trends in students' religious activities and attitudes between 1973 and 1983 were studied at the University of Maryland, College Park. A questionnaire was administered to a sample of 270 incoming freshmen in 1973 and to 389 freshmen in 1983. Findings suggest a continuation of the trend of decreasing religious orthodoxy among students, with both groups showing little interest in participating in organized religious activities. The most notable change among students over the 10-year period appeared to be in designated religious preference and attitudes toward moral issues. Though the three traditionally dominant religions (Catholic, Jewish, and Protestant) were still indicated by the majority of students, a marked decrease in students indicating Jewish was shown in 1983 compared to 1973. Students in 1983 also indicated less supportive attitudes toward abortion, premarital sex, and the buying of term papers, and more supportive attitudes toward personal involvement in war. Analysis of sex differences indicated that females, compared to males, tended to have differing views of God, more positive attitudes toward religious activity, and appeared more supportive of integrating religion more broadly into their lives. Blacks differed from whites on religious preferences, views of God, and attitudes toward several issues. (Author/SW)
