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.

摘要 可燃烟草(香烟)和电子尼古丁输送系统中的尼古丁消费 在美国，蒸发已经成为一种严重的健康威胁，特别是在青少年中。 几十年的研究记录了青少年社交网络的许多方式，特别是友谊 网络，影响烟草产品的启动、继续使用和品牌选择。然而，到目前为止， 目前还没有关于友谊网络如何影响终端使用的数据或研究。这项研究通过以下方式解决了这一差距 建议在两个新发起的队列中增加友谊网络问题，大约有2500个高 每名学生都在测量末端的使用量。已经为数据收集获得了资金 将于2019年11月和2020年10月开始。IRB批准添加社交网络 在咨询了南加州大学办公室主任以进行保护后，问题已提交给IRB 人类受试者的。将增加的友谊网络问题要求学生说出他们最亲近的人的名字 在学校里他们年级的朋友。所有同意的学生的名字都被预先录入到花名册中，以便 输入几个字母后，姓名会自动填充。这一过程已经在其他非尼古丁中实施 学习和工作都很好。然后这些数据将被用来测试青少年是否受到他们的 朋友开始和继续使用终端，以及朋友是否影响品牌和口味的选择 吸食大麻。此外，还将测试网络选择过程，这将发生在人们进行 网络变化要与他们的行为一致。需要检验的其他假设包括确定 同伴的影响和选择：(1)在同性和/或更强的联系中更强；(2)延伸到 两用或多用；(3)品牌和口味的选择；(4)两用和大麻的使用。 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 网络变化与不同的轨迹相关联。总而言之，这项提议代表着一个及时的 为两个新启动的校本青少年资助队列增加关键数据的机会 结束学习；即友谊网络数据。来自1,616个横截面样本的初步数据 南达科他州一个学区的学生显示，个体蒸发和 朋友间的交流。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，如面向随机参与者的模型。
