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.

项目概要 我建议使用二元、自我中心、两种模式来实施创新和先进的社交网络建模 网络和多层次中介分析来回答以下研究问题：拉丁裔文化如何 价值观和文化适应压力影响社交网络的配置和动态，然后可以充当 物质使用障碍 (SUD) 和 HIV 风险的保护性或危险因素？ K99 阶段：使用我的导师的指导 杰出的学术生涯作为范例和指南，再加上国际社会专家的培训 网络分析——我将接受五个关键领域的指导培训，以获得：（1）关于 SUD 和 HIV 的知识 流行病学，(2) 跨文化研究的理解，(3) 高级社交网络分析技能，(4) 对社交网络转化研究的理解，以及 (5) 专业发展 R01 阶段：跨领域。 将使用 R00 阶段（男性）收集的数据来实施分段社交网络研究 以及 2015 年 3 月至 12 月期间已收集的二手数据（针对女性）。总样本将 由 40 个以自我为中心的网络（20 组男性和 20 组女性）组成，每个网络由 13 我将分析以下人群之间的关联：(1) SUD 和 HIV 风险；(2) 拉丁裔 文化价值观（家庭凝聚力、玛丽亚主义、大男子主义和宗教信仰）和文化适应压力；以及（3） 以下社交网络因素： (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（设置 相互连接的个人），网络位置的影响，例如高中心性（例如， 受欢迎），以及基于 SUD 或 HIV 风险状况的自我选择友谊的影响； 结构因素：隶属关系网络结构（社交场所或季节性工作类型）。 该计划不仅能让我为进行拟议的横断面研究做好准备，而且还将为我提供 具备提交 R01 申请所需的背景知识（基于纵向设计），这将 让我了解随着时间的推移，社交网络的变化如何将拉丁裔季节性工人社区置于 这些信息将转化为创新且具有成本效益的成果。 预期成果还包括社会建模和统计程序的进步。 网络研究和新知识将为公共政策提供信息。
