Influences Of In-Person Social Networks, Digital Social Networks And Neighborhoods On Adolescent Alcohol Consumption

项目摘要 这个指导研究科学家发展奖（K 01）将为克里斯托弗莫里森博士提供支持 培养成为独立调查员审查环境预防所需的技能 减少青少年饮酒和酒精相关危害的战略。酒精消费量 21岁以下的青少年是一个重要的公共卫生问题，因为酒精导致4300多人死亡。 每年都有青少年死亡，并增加了酒精使用障碍和晚年其他问题的风险。 课程，导师和研究的综合计划将使莫里森博士完成三个 培训目标：培养全面的专业知识1）理论，数据收集和统计分析， 社交网络; 2）在纵向和地理参照的研究方法和统计分析方面 调查数据，以及3）进行研究，以评估接触社交媒体作为酒精的决定因素 青少年消费。该研究计划包括两个互补的研究。第一个是 创新性地使用从青少年到成人健康的国家纵向研究的第一波到第四波的数据（补充） 健康），这是一项对1994/1995年的青少年进行的以学校为基础的抽样纵向研究。 参与者的饮酒量将与其朋友的饮酒量有关，其特征和 他们的社交网络的结构，以及他们所居住的社区的特征（例如， 无组织，酒精出口密度）。第二项研究使用的数据来自青少年健康社区 (HCT)，一项正在进行的261例14-16岁青少年研究（R 01-HD 078415; PI：Byrnes，H）， 邻里接触和酒精消费。后续数据收集将评估参与者的 与数字社交媒体的接触，他们通过数字社交媒体接触酒精， 他们的数字社交网络。研究一，使用添加健康数据，将解决两个具体目标：1）建立一个 多尺度和动态模型的青少年的酒精消费的基础上，他们的位置在社会 网络，网络的结构，以及其他成员对酒精的态度和行为，以及2） 评估社交网络、邻里条件和饮酒之间的相互关系， 青春期，以及对酒精消费的影响进入青年期。研究二，使用HCT数据， 解决目标3）通过面对面的社交网络测试酒精暴露的不同影响， 数字社交网络对青少年饮酒的影响。研究的短期目标是 确定通过哪些人、在哪些地方、以及通过哪些人与数字平台， 社交网络对青少年饮酒的影响最大。整个职业生涯 发展计划将为莫里森博士发展成为独立科学家提供关键支持， 对青少年的酒精消费及其社会和物质环境进行创新性研究， 并确定有效预防干预的领域。

PROJECT SUMMARY This Mentored Research Scientist Development Award (K01) will provide support for Dr. Christopher Morrison to develop the skills necessary to become an independent investigator examining environmental prevention strategies to reduce adolescent alcohol consumption and alcohol-related harms. Alcohol consumption by adolescents under 21 is an important public health problem because alcohol contributes to over 4,300 adolescent deaths every year and to increased risks for alcohol use disorders and other problems in later life. An integrated program of coursework, mentorship and research will allow Dr. Morrison to accomplish three training objectives: developing comprehensive expertise 1) in theory, data collection, and statistical analysis for social networks; 2) in research methods and statistical analysis for longitudinal and geographically referenced survey data, and 3) conducting research to assess exposure to social media as a determinant of alcohol consumption among adolescents. The research program comprises two complementary studies. The first is an innovative use of data from Waves I to IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health), an ongoing longitudinal study of a school-based sample who were adolescents in 1994/95. Participants' alcohol consumption will be related to their friends' alcohol consumption, the characteristics and structures of their social networks, and characteristics of the neighborhoods in which they live (e.g. social disorganization, alcohol outlet density). The second study uses data from Healthy Communities for Teens (HCT), an ongoing study of 261 adolescents aged 14-16 years (R01-HD078415; PI: Byrnes, H) of neighborhood exposures and alcohol consumption. A follow-up data collection will assess participants' engagement with digital social media, their exposure to alcohol through digital social media, and the structure of their digital social networks. Study One, using Add Health data, will address two Specific Aims: 1) to build a multiscale and dynamic model of adolescents' alcohol consumption based on their location within a social network, the structure of the network, and other members' attitudes and behaviors towards alcohol, and 2) to assess interrelationships between social networks, neighborhood conditions, and alcohol consumption during adolescence, and the effects on alcohol consumption into young adulthood. Study Two, using HCT data, will address Aim 3) to test the differential effects of exposure to alcohol through in-person social networks and digital social networks on adolescent alcohol consumption. The short-term objective of the research is to identify the people through whom, the places where, and the in-person vs. digital platforms through which social networks most substantially influence adolescents' alcohol consumption. The overall career development program will provide critical support for Dr. Morrison to progress to independent scientist, conducting innovative studies of adolescents' alcohol consumption and their social and physical environments, and identifying areas for effective preventive intervention.
