Multilevel approaches for embracing dyadic, egocentric and two-mode networks which address substance use disorders and HIV risk in Latina seasonal workers

项目摘要 我建议使用二元、以自我为中心的两种模式实施创新和高级的社交网络建模 网络，以及多层次的调解分析，以回答以下研究问题：拉丁裔文化如何 价值观和文化适应压力会影响社交网络的配置和动态，进而可能起到 物质使用障碍(SODS)和艾滋病毒风险的保护性因素或风险因素？K99阶段：使用我导师的 杰出的学术生涯作为榜样和指南--再加上国际社会专家的培训 网络分析-我将在五个关键领域接受指导培训，以获得：(1)关于性病和艾滋病毒的知识 流行病学，(2)对跨文化研究的理解，(3)高级社会网络分析技能，(4) 对社交网络翻译研究的理解，以及(5)专业发展。R01阶段：一个交叉 将使用在R00阶段收集的数据(针对男性)实施分段社交网络研究 以及2015年3月至12月期间已经收集的(针对女性的)次要数据。总样本量为 由40个以自我为中心的网络(20组男性和20组女性)组成，每组将由13人组成 年龄在18岁以上的人(N=520)。我将分析以下两者之间的联系：(1)SUD和HIV风险；(2)拉丁裔 文化价值观(家庭凝聚力、马里亚主义、男子汉气概和宗教信仰)和文化适应压力；以及 下列社会网络因素：(A)个人因素：社会人口特征；(B)社会因素： 二元依恋、社会支持和家庭特征、亲密朋友或派系的直接影响(SET 所有相互连接的个人)、诸如高中心性的网络位置的影响(例如， 受欢迎)，以及基于SUD或艾滋病毒风险状况的自我选择友谊的影响；以及，(C) 结构性因素：隶属关系网络结构(社交场所或季节性工作类型)。这是K99/R00 该计划不仅为我进行拟议的横断面研究做好准备，而且还将为我提供 有了提交R01申请所需的背景知识-基于纵向设计-这将 请允许我了解随着时间的推移，社交网络的变化如何将拉美裔季节性工人社区置于 肥皂泡和艾滋病毒的风险代代相传。这些信息将转化为创新和具有成本效益的 干预措施。预期成果还包括在社会福利的建模和统计程序方面取得进展 网络研究和新知识将为公共政策提供信息。

Project Summary I propose to implement innovative and advanced social network modeling using dyadic, egocentric, two-mode network, and multilevel mediation analyses to answer the following research question: How do Latino cultural values and acculturation stress impact social network configurations and dynamics that could then act as protective or risk factors for substance use disorders (SUDs) and HIV risk? K99 Phase: Using my mentors' exceptional academic careers as an example and guide—coupled with training by international experts in social network analysis—I will receive mentored training in five key areas to obtain: (1) knowledge on SUD and HIV epidemiology, (2) comprehension of cross-cultural research, (3) advanced social network analytical skills, (4) comprehension of social network translational research, and (5) professional development. R01 Phase: A cross- sectional social network study will be implemented using data collected during the R00 phase (for males) as well as secondary data already collected (for females) between March and December 2015. The total sample will consist of 40 egocentric networks (20 groups of men and 20 groups of women) that will each be comprised of 13 people at least 18 years of age (N=520). I will analyze associations between: (1) SUD and HIV risk; (2) Latino cultural values (family cohesion, marianismo, machismo and religiosity) and acculturation stress; and, (3) the following social network factors: (a) individual factors: socio-demographic characteristics; (b) social factors: dyadic attachments, social support and family characteristics, direct influences from close friends or cliques (set of individuals all connected to each other), influences of network positions such as high centrality (for example, being popular), and influence from self-selection friendships based on SUD or HIV risk status; and, (c) structural factors: affiliation network structures (social venues or types of seasonal work). This K99/R00 program will not only prepare me for performing the proposed cross-sectional study but will also provide me with the background knowledge needed to submit an R01 application—based on a longitudinal design—that will allow me to understand how changes in social networks over time place Latino seasonal worker communities at risk for SUDs and HIV across generations. This information will translate into innovative and cost-effective interventions. Expected outcomes also include advances in modeling and statistical procedures for social network research and new knowledge that will inform public policy.
