Family and Peer Influences on Adolescent Sexual Behavior

描述（由申请人提供）：本提案旨在扩大对青少年艾滋病毒/性病风险的影响的研究基础，这是2010年健康人群的一个优先事项。具体来说，拟议的研究将增加我们对父母和同伴关系在性风险中的作用的理解，以及性和药物使用的共同发生。本研究的目的是：1)探讨青少年时期同伴选择和社会化对高危性行为、性行为和物质使用的共同发生以及青少年结果（如艾滋病毒/性病诊断）的影响；2)探讨父母教养和家庭关系对青少年性态度和性行为的直接影响；3)探讨家庭和同伴影响之间的相互作用对高危性行为、性态度和性行为的影响。性行为和吸毒同时发生。同伴影响的概念是通过对性代价的行为和态度进行选择和社会化的同时过程。待研究的家庭影响包括父母的参与、沟通、亲密、态度以及父母对高危性行为和预防性传播疾病的沟通。来自全国青少年健康纵向研究（Add-Health）饱和学校子样本的数据将被用来创建一个三波数据集（2波青少年，1波年轻人）来解决这些问题。在适当的情况下，将使用项目反应理论和验证性因素分析方法创建性态度、物质使用和艾滋病毒/性病诊断的综合测量。具有适合因变量的分布和联系的广义线性模型将用于检验与这些目标相关的假设。本研究的结果将通过增加我们对同伴影响的理解以及父母和同伴对性行为的影响之间的相互作用，帮助家庭干预和同伴规范干预的开发者。

DESCRIPTION (provided by applicant): This proposal seeks to expand the research base regarding influences on adolescent HIV/STD risk, a priority of Health People 2010. Specifically, the proposed research will add to our understanding of the role of parenting and peer relationships in sexual risk and the co-occurrence of sex and substance use. The aims of this proposal are to 1) to explore the effects of peer selection and socialization during adolescence on high risk sex, the co-occurrence of sex and substance use, and young adult outcomes such as HIV/STD diagnoses, 2) explore the direct effects of parenting and family relationships on adolescent attitudes and behaviors related to sex, and 3) explore the effects of the interaction between family and peer influences on high risk sex, attitudes about sex, and the co-occurrence of sex and substance use. Peer influence is conceptualized as a simultaneous process of selection and socialization through behavior and attitudes regarding the costs of sex. Family influences to be studied are parental involvement, communication, closeness, attitudes, and parental communication about high risk sex and prevention of sexually transmitted diseases. Data from the saturated schools sub-sample of the National Longitudinal Study of Adolescent Health (Add-Health) will be used to create a three-wave data set (2 adolescent waves, 1 young adult wave) to address these questions. Composite measures of sexual attitudes, substance use, and HIV/STD diagnoses will be created using item response theory and confirmatory factor analysis methods where appropriate. Generalized linear models with distributions and linkages appropriate for the dependent variables will be used to test hypotheses related to each of these aims. The results from this research will assist developers of family interventions and interventions addressing peer norms by adding to our understanding of peer influences and the interaction between parent and peer influences on sexual behavior.
