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“年轻男子隶属关系项目（YMAP）”，以通过引入一种解决与与健康相关行为有关的社交网络的基本问题来推动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与男性（YMSM）16-29岁发生性关系的年轻男性的风险和健康场所的分离网络，及其与人类免疫缺陷病毒（HIV）和性传播感染（STIS）的传播的关系。已经证明了社交网络分析的效用，以了解如何通过性或吸毒行为通过“风险网络”传播传染病。但是，社交网络分析很少仅用于研究与风险空间的隶属关系，艾滋病毒风险行为可以发生或促进艾滋病毒保护行为的情况，从而更普遍地有助于疾病传播或健康行为。涉及风险和健康场所的复杂且潜在竞争的基于竞争的隶属关系模式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，而另一些则导致健康；这种动态知之甚少，但反映了干预的关键点。 YMAP的目的是调查与YMSM基于YMSM基于YMSM的社交网络的复杂网络相关的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（即场地隶属关系导致行为），以及基于行为同质的场所的选择性隶属关系（即具有相似行为的YMSM导致场地隶属关系）。我们的具体目的是：1）确定YMSM之间社会互动的场所；考虑其个体特征，创建场地类别（即风险，健康或两者兼而有之）； 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HIV/STI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）开发纵向两模式网络方法来探索场地隶属关系的动态。该研究将使用混合方法设计，包括定性现场研究，纵向定量数据收集和新颖的社交网络分析。在休斯敦和芝加哥，将使用受访者驱动的抽样来招募种族和种族多样的700 YMSM样本。 YMAP将引入新的方法，用于测量基于隶属关系的网络影响力，隶属网络中的结构中心性以及使用两种模式指数随机图建模与行为相关的网络配置。此外，将在纵向数据的两波中探索与HIV/STI风险/保护行为相关的隶属网络动力学。 YMAP通过解决与健康和行为有关的社交网络的基本问题，并开发创新的方法来促进，改善和扩展社交网络分析的能力，从而直接回应了PAR。
