DESCRIPTION (provided by applicant): The goal of this proposal is to lay the foundation for the next generation of Peer Change Agent (PCA) HIV prevention interventions. Our approach is guided by identification of candidate PCAs according to their structural position within a social network and complements traditional approaches that utilize ethnographic observation or expert opinion. This intervention approach could dramatically reduce HIV incidence and bring us closer to HIV elimination. During the past 20 years, the most widely used PCA network based intervention for HIV prevention has been the opinion leader (OL) model or variants of it. These approaches and other PCA interventions include training popular members or peers from a target population to promote HIV prevention messages through interpersonal communication. Attempts to implement these models in diverse settings, however, have been disappointing. Fundamental questions, about the selection criteria for PCAs exist given the heterogeneity of approaches utilized and criteria for selection, has yet to be empirically tested. The effectiveness of the OL model can be further limited by several factors, including inadequate network assessments, and the OL's public position which often requires she/he maintain conformity to the status quo, thus potentially limiting innovation adoption. Consequently, identifying those who connect across groups (hereafter "bridging actors"), may be an alternative/complementary and efficient way to use network information to accelerate behavior change as has been demonstrated in workplace and management settings. In order to develop next generation PCA interventions, we approach gaps in social network data collection, network analysis and systematic PCA selection through the following Specific Aims: 1) Characterize a communication network through an approach that rapidly links Facebook friend lists of YBMSM on the South Side of Chicago. The communication network will be characterized as in recent work such that study respondents (n=300) rapidly generate a large linked MSM network (n=3500); 2) Measure attributes of individuals and dyads within the MSM network including sociodemographics leadership/innovation potential, condom communication, and tie qualities. These individual and dyadic attributes are believed to be important features of PCAs and will be determined by self-report and by report from others in the network; 3) Explore processes hypothesized to underlie behavior change in PCA interventions among both centrally located (popular) individuals and those who are in bridging positions (link distinct groups) within the network generated in Aim 1. We will identify candidate PCAs (n=30) who are selected based upon their network position and conduct in-depth qualitative interviews to assess candidate PCA behavior change elements that are considered to be important to PCA based interventions: education, social support, social norms, self-efficacy and advocacy.

描述（由申请人提供）：该提案的目标是为下一代同伴改变推动者（PCA）艾滋病毒预防干预措施奠定基础。我们的方法以根据候选 PCA 在社交网络中的结构位置进行识别为指导，并补充了利用人种学观察或专家意见的传统方法。这种干预方法可以显着降低艾滋病毒发病率，使我们更接近消除艾滋病毒。 在过去 20 年中，最广泛使用的基于 PCA 网络的 HIV 预防干预措施是意见领袖 (OL) 模型或其变体。这些方法和其他 PCA 干预措施包括培训目标人群中受欢迎的成员或同伴，通过人际沟通宣传艾滋病毒预防信息。然而，在不同环境中实施这些模型的尝试却令人失望。鉴于所使用的方法和选择标准的异质性，关于 PCA 选择标准的基本问题尚未得到实证检验。有效性 OL 模型的有效性可能会进一步受到多种因素的限制，包括网络评估不足，以及 OL 的公共地位，这通常要求她/他保持现状，从而可能限制创新的采用。因此，识别跨群体联系的人（以下简称“桥接参与者”）可能是使用网络信息加速行为改变的替代/补充和有效方法，正如工作场所和管理环境中所证明的那样。 为了开发下一代 PCA 干预措施，我们通过以下具体目标来弥补社交网络数据收集、网络分析和系统 PCA 选择方面的差距：1）通过快速链接芝加哥南区 YBMSM 的 Facebook 好友列表的方法来表征通信网络。通信网络将像最近的工作一样进行表征，以便研究受访者（n = 300）快速生成大型链接的 MSM 网络（n = 3500）； 2) 衡量 MSM 网络内个人和二人的属性，包括社会人口统计领导力/创新潜力、安全套沟通和领带质量。这些个体和二元属性被认为是 PCA 的重要特征，并将通过自我报告和网络中其他人的报告来确定； 3) 探索假设为 PCA 干预中行为改变的过程，这些过程位于目标 1 中生成的网络中的中心（受欢迎）个体和处于桥接位置（链接不同群体）的个体之间。我们将确定根据其网络位置选择的候选 PCA (n=30)，并进行深入的定性访谈，以评估候选 PCA 行为改变要素，这些要素被认为对基于 PCA 的干预措施很重要：教育、社会支持、社会 规范、自我效能和宣传。
