The author and colleagues examined campus resources for gay, lesbian, and bisexual (GLB) students at 119 US colleges to determine how the presence of such resources affected sexually active students' condom use. A random sample of unmarried, sexually active college students surveyed in 1999 completed questionnaires. Condom use was compared across schools with different levels of GLB resources. Condom use rates, analyzed by sex and sex-partner groups, ranged from 32% to 52%. With additional college variables controlled for, GLB resources were positively associated with the proportion of sexually active students who used condoms (p < .001). This association existed primarily for students with only opposite-sex partners. The author's findings suggest that campus resources for GLB students may be associated with college students' condom use.  相似文献

Family preservation services have been found effective in preventing the placement of children outside their homes. Most studies of family preservation services focus on the successful prevention of placement of children in out-of-home care, and relatively few studies have examined how such services affect family functioning. Recent research has begun to examine the relationship between family functioning and prevention of placement. This research has demonstrated improved family functioning for those families who received family preservation services.A version of this paper was first presented at the Sixth National Doctoral Dissertation Symposium, 1993, Ohio State University.  相似文献

Family systems propositions as applied to career development theory were tested in a cross-sectional survey examining the relationship between family members' perceptions of family functioning and adolescent career development measures. Results of the analysis showed that family functioning dimensions as evaluated by 11th-grade students and their parents were more frequent and stronger predictors of career development than gender, socioeconomic status, and educational achievement.  相似文献

The Anti-Tobacco Media Blitz (ATMB), a social-norms marketing program, was utilized for tobacco prevention with middle and high school students. University students assisted middle and high school students with the implementation of this campaign, which included a variety of media. Students worked in teams to design, develop, and evaluate tobacco-free messages through posters, radio, television, and peer-led activities. Evaluation of the campaign was constant and included assessment of message retention and demonstration of positive behaviors. This article discusses the procedures of this project, the five-step social norms marketing model, with emphasis on the student-centered evaluation and results.  相似文献
