Abstract Nicotine consumption in both combustible tobacco (cigarettes) and with electronic nicotine delivery systems (ENDS), or vaping, has become a serious health threat in the United States, particularly among adolescents. Decades of research have documented the many ways adolescent social networks, particularly friendship networks, influence the initiation, continued use, and brand choice of tobacco products. To date, however, there is no data or research on how friendship networks influence ENDS use. This study addresses this gap by proposing to add friendship network questions to two newly initiated cohorts of approximately 2,500 high school students each that are measuring ENDS use. Funding has already been acquired for the data collection for these cohorts and will start in November 2019 and October 2020. IRB approval to add the social network questions has been submitted to the IRB after consultation with the director of the USC office for the protection of human subjects. The friendship network questions to be added ask the students to name their closest friends in their grade at school. The names of all consented students are pre-entered into a roster so that the names auto-fill after a few letters are entered. This process has been implemented in other non-nicotine studies and works well. These data will then be used to test whether adolescents are influenced by their friends to initiate and continue ENDS use, as well as whether friends influence brand and flavor choices and marijuana uptake. In addition, network selection processes will be tested which occurs when people make network changes to be consistent with their behavior. Additional hypotheses to be tested include determining whether peer influence and selection: (1) are stronger among homophilous and/or stronger ties; (2) extends to dual- or poly-use; (3) occurs for brands and flavors choices; (4) occurs for dual ENDS and marijuana use. Given the longitudinal nature of the data we will construct ENDS and tobacco use trajectories and determine if network changes are associated with different trajectories. In sum, this proposal represents a timely opportunity to add a crucial piece of data to two newly initiated funded cohorts of school-based adolescent ENDS studies; namely, friendship network data. Preliminary data from a cross-sectional sample of 1,616 students in one school district in South Dakota showed a strong correlation between individual vaping and friend vaping. Longitudinal data are needed to determine the direction of this relationship and apply more sophisticated analytic techniques such as stochastic actor-oriented models.

抽象的 可燃烟草（香烟）和电子尼古丁输送系统的尼古丁消耗 （末端）或vaping在美国，特别是在青少年中成为严重的健康威胁。 数十年的研究记录了青少年社交网络的多种方式，尤其是友谊 网络，影响启动，继续使用和品牌选择烟草产品。但是，迄今为止 没有关于友谊网络如何影响目的使用的数据或研究。这项研究解决了这一差距 提议将友谊网络问题添加到两个新发起的大约2500个新的人群中 校学生每个都在测量目的的使用。资金已经被用于数据收集 对于这些队列，将于2019年11月和2020年10月开始。IRB批准添加社交网络 在与USC办公室董事协商后，问题已提交给IRB。 人类主题。要添加的友谊网络问题要求学生命名他们最接近 朋友在学校成绩。所有同意学生的名字都被预先进入花名册，以便 输入几个字母后的名称自动填充。此过程已在其他非纽约胺中实施 研究和效果很好。然后，这些数据将用于测试青少年是否受其影响 启动并继续结束使用的朋友，以及朋友是否影响品牌和风味的选择和 大麻吸收。此外，将测试网络选择过程，这是人们制作的 网络变化以与其行为一致。要测试的其他假设包括确定 同伴的影响和选择是否：（1）在同义和/或更强的联系中更强； （2）延伸到 双重或多用途； （3）为品牌和口味选择而发生； （4）发生双端和大麻使用。 鉴于数据的纵向性质，我们将构建末端和烟草使用轨迹，并确定是否 网络变化与不同的轨迹相关。总而言之，该提议代表及时 有机会将重要的数据添加到两个新发起的基于学校的青少年的资助 结束研究；即友谊网络数据。来自1,616的横截面样本的初步数据 南达科他州一个学区的学生表现出个人烟与 朋友烟。需要纵向数据来确定这种关系的方向并应用更多 复杂的分析技术，例如随机参与者的模型。
