The research goal is to analyze the determinants of dual method use among adolescents in order to better design and target prevention strategies related to STD/HIV and pregnancy. The analysis will utilize a nationally representative sample of adolescents that will permit identification of racial/ethnic variation in the determinants of dual method use. Extant research documents wide variation in the proportion of adolescents who use dual methods; yet the published literature has predominantly focused on demographic correlates analyzed atheoretically or with theories or data sets lacking contextual determinants of behavior. Using the Theory of Triadic Influences, an integrating framework for understanding the interplay among social, attitudinal, and intrapersonal influences on health behavior, analyses will explicate determinants of dual method use. Analyses will utilize one year longitudinal data from the National Longitudinal Study of Adolescent Health, including adolescent in-home interview, parent questionnaire, friendship nomination and school administrator datasets. This includes a multi-ethnic sample of 12,000 adolescents, grades 7- 12, with over-sampling of minority and special populations bringing the total sample to 20,530. The target sample will include adolescents who reported ever having sexual intercourse (N=9,427) at Time 1 or 2. The following aims guide the research plan for multivariate, longitudinal analyses: AIM I Describe patterns of dual contraceptive use within sexual relationships, over time, and across partners. Based on these patterns, empirically derive approaches to operationalizing "dual method use" of STD/HIV and pregnancy protection as a categorical as well as a continuous variable that will be used in subsequent analyses. AIM II Examine determinants of consistency of dual method use through the testing of models mapping relationships between T1 variables, including T1 dual method use, and T2 dependent variables. This includes examination of direct, moderating, and mediating effects on T2 dual method use as defined by the conceptual model. AIM III Examine T1 and T2 determinants of T2 patterns of dual method use, comparing models across gender groups and racial/ethnic groups: Euro-American, African-American, and Hispanic. The analytic plan moves from construct validation to structural equation modeling to understand mechanisms by which social, attitudinal, and intrapersonal influences affect dual method use, over time and across sexual partners. It will also contribute to the, as yet, underdeveloped knowledge base of adolescent dual method use.

研究目的是分析青少年双重方法使用的决定因素，以更好地设计和针对与性病/艾滋病毒和怀孕有关的预防策略。 该分析将利用全国代表性的青少年样本，这些样本将允许在双重方法使用的决定因素中识别种族/种族差异。 现有的研究记录了使用双重方法的青少年比例的广泛差异；然而，已发表的文献主要集中在人口统计学相关性上，分析了人的理论或缺乏行为上下文决定因素的理论或数据集。 利用三合会影响理论，是一个综合框架，用于理解社会，态度和人际影响健康行为之间的相互作用，分析将阐明双重方法使用的决定因素。 分析将利用国家青少年健康纵向研究的一年纵向数据，包括青少年内访谈，家长问卷，友谊提名和学校管理员数据集。 这包括一个多民族的样本，包括12,000名青少年，年级7至12年级，少数族裔和特殊人群过度采样，使总样本达到20,530。 目标样本将包括在时间1或2时报告有性交的青少年（n = 9,427）。以下目的指导了多变量，纵向分析的研究计划：目的I I描述了在性关系，随着时间的时间和整个伴侣的性关系中双重避孕药的模式。 基于这些模式，从经验上得出了将STD/HIV和妊娠保护的“双重方法使用”作为分类和连续变量的“双重方法使用”，这些方法将用于随后的分析。 AIM II通过测试模型映射T1变量之间的模型关系（包括T1双重方法的使用和T2依赖变量）的模型映射关系来研究双重方法使用的一致性。 这包括对概念模型定义的T2双重方法的直接，调节和中介作用的检查。 AIM III检查了双重方法使用T2模式的T1和T2决定因素，比较了性别群体和种族/种族群体的模型：欧美，非裔美国人和西班牙裔。分析计划从构造验证到结构方程建模，以了解社会，态度和人际影响影响双重方法的机制，随着时间的流逝和跨性伴侣的跨性伴侣。 它还将有助于青少年双重方法的欠发达知识基础。
