The contraceptive behavior of 213 sexually active never-married U.S. college students was examined using multiple regression analyses. The type of relationship--casual or steady--was a major determinant of contraceptive use: 77 percent of the respondents involved in steady relationships reported using condoms or the pill, compared with 58 percent of the respondents involved in casual relationships. Frequency of intercourse was the best predictor of contraceptive method used within steady relationships. Several variables emerged as predictors of contraceptive method used within casual relationships, including method used at first coital experience, age, and frequency of intercourse. Situational and background factors were found to have an important impact on adolescent contraceptive behavior and to warrant further research.
通过多元回归分析，对213名有性活动的未婚美国大学生的避孕行为进行了研究。恋爱关系的类型——随意的还是稳定的——是使用避孕措施的一个主要决定因素：处于稳定恋爱关系中的受访者中有77%报告使用避孕套或避孕药，而处于随意恋爱关系中的受访者这一比例为58%。性交频率是稳定恋爱关系中使用避孕方法的最佳预测指标。在随意恋爱关系中，有几个变量成为了使用避孕方法的预测指标，包括首次性交时使用的方法、年龄和性交频率。研究发现，情境和背景因素对青少年的避孕行为有重要影响，值得进一步研究。
