We examine the relationship characteristics associated with contraceptive method choice within young people's nonmarital sexual relationships, using data from retrospective relationship histories available in the third wave (2001-2002) of the National Longitudinal Study of Adolescent Health. Data-reduction techniques produce a detailed multidimensional characterization of relationship commitment for nonmarital sexual relationships. We then use multilevel analysis to estimate associations between two key relationship characteristics-relationship commitment and couple heterogamy-and the type of contraceptive method used at last sexual intercourse within each relationship. Results indicate that for a given individual, contraceptive method choice varies across relationships as a function of these characteristics, even after we account for important individual and family characteristics and prior relationship experiences.
我们利用全国青少年健康纵向研究第三波(2001-2002 年)中可获得的回顾性关系史数据,研究了年轻人非婚姻性关系中与避孕方法选择相关的关系特征。数据简化技术为非婚姻性关系的关系承诺提供了详细的多维特征描述。然后,我们使用多层次分析来估计两个关键关系特征——关系承诺和夫妻异质性——与每种关系中最后一次性行为中使用的避孕方法之间的关联。结果表明,对于给定的个体,即使考虑到重要的个体和家庭特征以及先前的关系经历,避孕方法的选择在不同关系中也会因这些特征而异。
