DESCRIPTION (provided by applicant): We propose a study, the "Young Men's Affiliation Project (YMAP)," to advance the utility of social network analysis by introducing a new way of addressing fundamental questions about social networks in relation to health-related behavior. We apply novel two-mode network methodologies to study the risk and health venue- based affiliation networks of younger men who have sex with men (YMSM) ages 16-29 and their relation to the transmission of human immunodeficiency virus (HIV) and sexually transmitted infections (STIs). The utility of social network analysis for understanding how infectious diseases are spread through "risk networks" based on sexual or drug use behaviors has been demonstrated. However, social network analysis has only rarely been utilized for investigating how affiliation with risk spaces, where HIV risk behavior can take place or health spaces, where HIV protective behaviors are promoted, contributes to disease transmission or health behavior more generally. Complex and potentially competing venue-based affiliation patterns, involving both risk and health venues may create networks with competing influences, some of which may contribute to risk and others to health; this dynamic is poorly understood, but reflects critical points for intervention. The purpose of YMAP is to investigate the HIV/STI risk and protective behaviors associated with complex webs of social networks created by YMSM's venue-based affiliations. YMAP will investigate and describe network influences on individuals' behavior (i.e., venue affiliation leads to behavior), as well as selective affiliation with venues based on behavioral homophily (i.e., YMSM with similar behaviors leads to venue affiliation). Our specific aims are to: 1) Identify venues where social interaction among YMSM occurs; create venue categories (i.e., risk, health, or both) considering their individual characteristics;2) Determine network influences on HIV/STI risk/protective behavior through risk and health venue affiliation and compare them by geographic location; 3) Investigate selective affiliation with venues based on similarity in HIV/STI risk and protective behaviors; and 4) Develop longitudinal two-mode network methodology to explore the dynamics of venue affiliation. The study will be implemented using a mixed method design, including qualitative field research, longitudinal quantitative data collection, and novel social network analyses. A racially and ethnically diverse sample of 700 YMSM will be recruited using respondent driven sampling in Houston and Chicago. YMAP will introduce new approaches to measuring affiliation-based network influence, structural centrality in affiliation networks, and estimating network configurations relating to behavior using two-mode exponential random graph modeling. Furthermore, the dynamics of affiliation networks in relation to HIV/STI risk/protective behaviors will be explored in two- wave of longitudinal data. YMAP responds directly to the PAR by addressing fundamental questions about social networks in relation to health and behavior, and to develop innovative methodologies to facilitate, improve, and expand the capability of social network analysis.

描述（由申请人提供）：我们提出了一项研究，即“年轻人归属项目（YMAP）”，通过引入一种解决与健康相关行为有关的社交网络基本问题的新方法来提高社交网络分析的实用性。我们应用新颖的两种模式网络方法来研究 16-29 岁男男性行为者 (YMSM) 的基于风险和健康场所的隶属网络及其与人类免疫缺陷病毒 (HIV) 和性传播疾病传播的关系感染（性传播感染）。社交网络分析对于了解传染病如何通过基于性行为或吸毒行为的“风险网络”传播的实用性已经得到证明。然而，社交网络分析很少被用来调查与可能发生艾滋病毒风险行为的风险空间或促进艾滋病毒保护行为的健康空间的联系如何促进疾病传播或更广泛的健康行为。复杂且潜在竞争的基于场馆的隶属模式，涉及风险场馆和健康场馆，可能会创建具有竞争影响力的网络，其中一些可能会导致风险，另一些则可能会导致健康；人们对这种动态知之甚少，但它反映了干预的关键点。 YMAP 的目的是调查与 YMSM 的场所附属机构创建的复杂社交网络相关的 HIV/STI 风险和保护行为。 YMAP 将调查和描述网络对个人行为的影响（即，场所归属导致行为），以及基于行为同质性的场所选择性归属（即，具有相似行为的 YMSM 导致场所归属）。我们的具体目标是： 1) 确定 YMSM 之间进行社交互动的场所；考虑其个体特征，创建场所类别（即风险、健康或两者）；2) 通过风险和健康场所隶属关系确定网络对 HIV/STI 风险/保护行为的影响，并按地理位置进行比较； 3) 根据艾滋病毒/性传播感染风险和保护行为的相似性，调查与场所的选择性隶属关系； 4) 开发纵向两种模式网络方法来探索场地归属的动态。该研究将采用混合方法设计来实施，包括定性实地研究、纵向定量数据收集和新颖的社交网络分析。将使用休斯顿和芝加哥的受访者驱动抽样方法招募 700 名 YMSM 中的种族和族裔多样化样本。 YMAP 将引入新方法来测量基于关联的网络影响力、关联网络的结构中心性，并使用两种模式指数随机图建模来估计与行为相关的网络配置。此外，将在两波纵向数据中探讨与 HIV/STI 风险/保护行为相关的隶属网络动态。 YMAP 通过解决与健康和行为相关的社交网络的基本问题来直接响应 PAR，并开发创新方法来促进、改进和扩展社交网络分析的能力。
