项目摘要

DESCRIPTION (provided by applicant): The goal of the proposed research is to extend one-mode network data analysis of friendship relations (actor-by-actor network) to two-mode (actor-by-event affiliation/bipartite) network data to model the influence of co-participation in school-based organized activities on adolescent alcohol use. The first aim is to determine the utility of a new conceptualization of affiliation-based network influence by directly modeling (using multiple Network Autocorrelation Models) the effect of two-mode/affiliation exposure on drinking behavior controlling for other competing peer influences primarily those based on close friends or peers occupying similar network position. The second aim is to determine the relative contributions of multiple forms of network effects on alcohol use, and how these network effects operate together as risk factors. The research during the R00 phase will focus on structural properties and the dynamics of two-mode network structural analysis of affiliation networks in relation to alcohol. Related to this, the third aim is to estimate the new specification of two-mode Exponential Random Graph Model (ERGM) with geometric weighting technique to test the effects of co-affiliation on adolescent alcohol use, and it will be extended to longitudinal analysis by stochastically modeling the co-evolution of one-mode and two-mode networks to examine the cross-dependencies in the evolution of friendship and affiliation networks in relation to alcohol use within an actor-based modeling framework. The fourth aim is to explore social mechanisms that drive joint dynamics of affiliation network structures conditioned on one-mode friends' networks in relation to alcohol use. Addressing these questions would help establish the PI's long-term career goal of establishing herself as a specialist in two-mode network, which is separate and distinct from the primary mentor's (Thomas Valente) main approach of analyzing one-mode networks in the study of peer influence on substance use centered on adolescent alcohol use. Research for both K99 and R00 phase use data from both the National Longitudinal Study of Adolescent Health (Add Health) and from USC-collected data. Not only does the proposed study have the potential to provide insight into how school-based alcohol prevention program based on social influence model should be implemented, the proposed approach of using two-mode network data does not require the collection of network data (sociometrics). Therefore this methodology has the potential to be applied to a wide variety of studies and used in various fields of public health that traditionally have not been able to use network methods. PUBLIC HEALTH RELEVANCE: The research plan specifically uncovers new modes f peer influence that will help understand the etiology and amelioration of adolescent alcohol (and other substance) use, it explicitly addresses the NIH mission of producing knowledge related to the "behavior of living systems and the application of that knowledge to extend healthy life and reduce the burdens of illness and disability." PUBLIC HEALTH RELEVANCE: The goal of the proposed research is develop and explore the possibilities of the transmission of substance use through group affiliations, frequently in the form of school-sponsored sports or similar activities. If affiliation exposure has anywhere near the explanatory power of traditional social influence models, the expanded opportunities for data collection and influence estimation using data that is traditionally collected but not used in this way will provide a substantial new source of insight for understanding the etiology and amelioration of adolescent alcohol (and other substance) use.

描述（由申请人提供）：拟议研究的目标是将友谊关系（演员到演员网络）的单模式网络数据分析扩展到双模式（演员到事件隶属关系/二分）网络数据，以模拟共同参与学校组织的活动对青少年饮酒的影响。第一个目标是通过直接建模（使用多个网络自相关模型）两种模式/隶属关系暴露对饮酒行为的影响来确定基于隶属关系的网络影响力的新概念的效用，控制其他竞争性同伴影响力主要基于占据类似网络地位的亲密朋友或同龄人。第二个目标是确定多种形式的网络效应对饮酒的相对贡献，以及这些网络效应如何作为风险因素一起发挥作用。 R00阶段的研究将重点关注与酒精相关的隶属网络的结构特性和两种模式网络结构分析的动态。与此相关，第三个目标是利用几何加权技术来估计双模式指数随机图模型（ERGM）的新规范，以测试共同隶属关系对青少年饮酒的影响，并将其扩展到纵向分析：对一种模式和两种模式网络的共同进化进行随机建模，以在基于参与者的建模框架内检查与饮酒相关的友谊和归属网络进化中的交叉依赖性。第四个目标是探索推动以与饮酒相关的单一模式朋友网络为条件的归属网络结构联合动态的社会机制。解决这些问题将有助于确立 PI 的长期职业目标，将自己打造成双模网络专家，这与主要导师 (Thomas Valente) 在研究中分析单模网络的主要方法是分开且不同的。同伴对物质使用的影响集中在青少年饮酒上。 K99 和 R00 阶段的研究均使用来自国家青少年健康纵向研究 (Add Health) 和南加州大学收集的数据的数据。拟议的研究不仅有可能深入了解如何实施基于社会影响模型的学校酒精预防计划，而且所提出的使用两种模式网络数据的方法不需要收集网络数据（社会计量学）。因此，该方法有潜力应用于各种研究，并用于传统上无法使用网络方法的公共卫生各个领域。公共卫生相关性：该研究计划特别揭示了同伴影响的新模式，这将有助于了解青少年酒精（和其他物质）使用的病因和改善，它明确阐述了 NIH 的使命，即提供与“生命系统和其他物质的行为”相关的知识。应用这些知识来延长健康寿命并减少疾病和残疾的负担。” 公共卫生相关性：拟议研究的目标是开发和探索通过团体关系传播物质使用的可能性，通常以学校赞助的体育运动或类似活动的形式进行。如果从属关系暴露具有接近传统社会影响力模型的解释力，那么使用传统收集但不以这种方式使用的数据进行数据收集和影响力估计的扩大机会将为理解病因和改善提供重要的新见解来源青少年饮酒（和其他物质）的情况。
