DEVELOPMENTAL RELATIONS OF SUBSTANCE USE AND RISKY SEX

这项拟议的研究将检查儿童和青少年药物使用与成年后危险性行为之间的发展关系。该研究寻求一年的支持，使用来自西雅图社会发展项目（SSDP）的9波数据进行分析。这个性别平衡、多民族的城市小组由808名青年组成，成立于1985年，当时受访者进入五年级。小组中的年轻人被采访到21岁。在9个数据评估波中，大约91%的样本至少出现了7个。数据收集范围广泛的问题行为措施，如物质使用，性行为和犯罪。还收集了个人、家庭、学校、同伴和社区对这些问题行为的预测因素的数据。本研究将探讨儿童和青少年药物使用与成年后危险性行为之间的发展关系。具体来说，本研究将使用通用生长混合模型（GGMM）来研究儿童和青少年药物使用的发展轨迹及其与青年期危险性行为的关系。此外，在控制了药物使用和性行为的早期预测因素后，该研究将检查儿童和青少年药物使用对成年后危险性行为的独特影响程度。此外，将探讨物质使用和危险性行为之间可能的发展机制。将讨论药物使用与危险性行为之间的发展关系中的性别和种族差异。这项研究的结果将为青少年和年轻人预防性病/艾滋病的努力提供信息。郭博士最近完成了她关于高危性行为和避孕套使用的论文。目前，她正在从事nida资助的SDRG研究“物质使用和向成人角色的过渡”。她在高危性行为和物质使用预防方面的理论和研究知识，以及她在结构方程建模、缺失数据技术和多层次建模等多变量技术方面的统计专业知识，结合起来为拟议的研究提供了实质性和统计技能的平衡。拟议的研究将使她在预防领域建立自己的职业生涯。

The proposed study will examine the developmental relationship between childhood and adolescent substance use and risky sexual behaviors in young adulthood. The study seeks 1 year of support to conduct analyses using 9 waves of data from the Seattle Social Development Project (SSDP). The gender-balanced, multiethnic urban panel of 808 youths was constituted in 1985 when respondents entered the fifth grade. Youths in the panel were interviewed through age 21. Approximately 91 percent of the sample was present for at least seven of the nine data assessment waves. Data were collected on a wide range of measures of problem behaviors such as substance use, sexual behavior, and delinquency. Data were also collected on individual, family, school, peer, and community predictors of those problem behaviors. This study will examine the developmental relationship between childhood and adolescent substance use and risky sexual behavior in young adulthood. Specifically, this study will examine the developmental trajectories of childhood and adolescent substance use and their associations with risky sexual behavior in young adulthood using General Growth Mixture Modeling (GGMM). Further, the study will examine the extent to which childhood and adolescent substance use have unique effects on risky sexual behavior in young adulthood after controlling for early predictors of substance use and sexual behavior. In addition, possible developmental mechanisms that link substance use and risky sexual behavior will be explored. Gender and ethnic differences in the developmental relationship between substance use and risky sexual behavior will be addressed. Results from this study will inform STD/HIV prevention efforts for adolescents and young adults. Dr. Guo recently completed her dissertation on high risk sexual behavior and condom use. Currently she is working on the NIDA-funded SDRG study "Substance Use and the Transition to Adult Roles." Her knowledge of the theories and research on high risk sexual behavior and on substance use prevention, her statistical expertise in multivariate techniques such as structural equation modeling, missing data techniques, and multilevel modeling, combine to provide the balance of substantive and statistical skills required for the proposed study. The proposed study will allow her to establish a career in the field of prevention.
