DESCRIPTION (provided by applicant): The proposed renewal of the PROSPER Peers Project will improve efforts to prevent adolescent substance use and young adult sexual risk behaviors for HIV/AIDS by using the remarkable peer network data of the PROSPER prevention trial to advance knowledge of network influences during an age span that is largely unaddressed by prevention research and programming. To date we have studied friendship networks and the emergence of substance use among over 10,000 students across 5 waves of data for 6th-9th grade. In this continuation, we propose coding and analyzing 3 additional waves of peer network data through 12th grade and merging these data with outcome data at age 19 to 24, producing the largest and longest-term dataset on friendship networks and substance use in the world. The first aim of the project is to examine the contributions of friendship networks t substance use throughout late adolescence, adding a period of rapid growth in the rate and seriousness of risky behavior. The additional years of data will enable us to move beyond the most common substances (alcohol and tobacco) to use bringing greater harmful consequences for health and life prospects. The longer time span also will permit us to break new ground by examining the relation of trajectories of positions in friendship networks (e.g., popularity, isolation) to varying trajectories of use (e.g., earlier versus later onset; maintenance; escalatio). Our second aim is to expand the scope of our investigation to include the emerging domains of romantic relationships and depression to generate knowledge about how preventive interventions can best combat their contributions to substance use. We will examine romantic partnerships as bridges that may facilitate diffusion of substance use across distant pockets of peer networks. Depression also becomes considerably more prevalent during the high school years, and when combined with substance use, it foretells more problematic substance use. Our network data enable us to test the three proposed sources of depression's association with substance use using considerably more rigorous methods than prior work. Our third aim is to examine how adolescent friendships and substance use jointly contribute to sexual risk behavior that carries a high risk of HIV/AIDS, during the peak age of acquisition of HIV/AIDS, which is 20-24 years old. Both peers and substance use are associated with risky sexual behavior in adolescence, but little is known about their connection to sexual risk behavior at the key later ages. The final aim of our project is to test how friendship networks contribute to long-term impacts of prevention programs. Our study has the unique advantage of being embedded in the PROSPER community-level randomized trial of adolescent substance use prevention that has been shown to reduce substance use through at least 12th grade, and our prior work demonstrated that PROSPER succeeded in altering peer networks to reduce the potential for peer influence toward substance use. The additional years of data will enable us to assess the durability of program network effects and their role in mediating long-term effects.

说明（由申请人提供）：拟议更新的 PROSPER 同伴项目将通过使用 PROSPER 预防试验的出色同伴网络数据来提高对网络的了解，从而改进预防青少年药物滥用和青年人艾滋病毒/艾滋病性危险行为的努力预防研究和规划基本上未解决这一年龄跨度的影响。迄今为止，我们已经通过 6 至 9 年级的 5 波数据研究了超过 10,000 名学生的友谊网络和药物滥用的出现。在此延续中，我们建议对 12 年级的另外 3 波同伴网络数据进行编码和分析，并将这些数据与 19 至 24 岁的结果数据合并，生成世界上最大、期限最长的关于友谊网络和物质使用的数据集。该项目的首要目标是研究友谊网络对整个青春期后期药物使用的贡献，增加危险行为的发生率和严重性快速增长的时期。额外多年的数据将使我们能够超越最常见的物质（酒精和烟草），使用给健康和生活前景带来更大有害后果的物质。更长的时间跨度还将使我们能够通过检查友谊网络中的位置轨迹（例如，受欢迎程度、孤立性）与不同的使用轨迹（例如，较早发生与较晚发生；维持；升级）之间的关系来开辟新天地。我们的第二个目标是扩大我们的调查范围，将浪漫关系和抑郁症等新兴领域纳入其中，以产生有关预防性干预措施如何最好地对抗其对药物滥用的影响的知识。我们将研究浪漫伙伴关系作为桥梁，促进物质使用在遥远的同伴网络中扩散。抑郁症在高中时期也变得更加普遍，当与药物滥用相结合时，它预示着更多有问题的药物使用。我们的网络数据使我们能够使用比以前的工作更加严格的方法来测试抑郁症与药物滥用之间的关联的三种拟议来源。我们的第三个目标是研究在艾滋病毒/艾滋病感染的高峰年龄（20-24 岁），青少年友谊和药物滥用如何共同导致高风险性行为。同龄人和药物使用都与青春期的危险性行为有关，但人们对它们与关键后期性危险行为的关系知之甚少。我们项目的最终目标是测试友谊网络如何促进预防计划的长期影响。我们的研究具有独特的优势，即嵌入 PROSPER 社区级青少年药物使用预防随机试验中，该试验已被证明可以减少至少 12 年级的药物使用，而且我们之前的工作表明，PROSPER 成功地改变了同伴网络，以减少药物使用。同伴对药物使用的潜在影响。额外年份的数据将使我们能够评估项目网络效应的持久性及其在调节长期效应中的作用。
