Using TDM to understand mechanisms in adolescent health and risk behavior

项目摘要--项目1 青春期是身体活动和危险等健康行为发展的关键时期 饮酒等行为。青少年学习和塑造他们的行为的一种方式是通过技术 和数字媒体(TDM)，特别是社交媒体。青少年的行为会受到以下内容的影响 青少年在社交媒体上展示(自己产生的)，以及他们消费的(其他产生的)内容。这个 这项研究的长期目标是了解社交媒体影响健康和风险的机制 制定行为干预措施，促进健康行为，减少危险行为。这个 本项目1的目标是了解社会上表现出的健康和危险行为的模式和内容 由青少年创造和消费的媒体。我们将确定三个关键字之间的联系 通过我们的具体目标提出的概念，包括：1)青少年在TDM上关于他们自己的健康和 通过自生成内容的危险行为，2)青少年实时接触到的显示的TDM内容 关于健康和危险行为，以及3)青少年自我报告的健康和危险行为态度，社会 规范、意图和行动。我们的第三个目标将评估潜在的神经过程如何产生和消耗 TDM内容经过处理，并与健康和危险行为相关联。这方面的私人助理、协理和顾问 该项目在社交媒体上展示的青少年行为领域开展了十多年的工作，包括 美国国立卫生研究院资助的这一领域的几项研究。我们的初步数据表明，对于年龄较大的青少年来说，自我生成 TDM上的危险行为内容与自我报告的行为密切相关，生态瞬间 评估(EMA)可用于青少年人群评估TDM的实时使用和内容 曝光。本研究将采用纵向研究设计，收集两年多的数据。共享参与者 这一P01计划的资金池将被用来招募400名13-15岁的青少年 招生。数据收集方法将包括社交媒体对健康和危险行为的观察， 包括自生和他生。此社交媒体观察数据将链接到自我报告 调查数据包括态度、社会规范、意图和行为。主持人将包括技术 重要性和家长的参与。数据收集还将包括生态瞬时评估(EMA) 以确定青少年在整个TDM中实时接触自生成和其他生成的内容的情况。 最后，调查人员将在功能磁共振扫描期间利用社交媒体数据来确定自我生成和 其他生成的内容的处理方式不同。该项目与当前的RFA保持一致，因为它利用了多个层次 对健康和发展的评估，包括TDM暴露的实时测量。

PROJECT SUMMARY – PROJECT 1 Adolescence is a critical time period for the development of health behaviors such as physical activity and risk behaviors such as alcohol use. One way adolescents learn about and model their behaviors is via technology and digital media (TDM), particularly social media. Adolescent behavior can be influenced by content that adolescents display (self-generated) on social media, as well as content they consume (other-generated). The long-term goal of this research is to understand mechanisms by which social media influence health and risk behavior towards the development of interventions to promote healthy behavior and reduce risk behavior. The objective of this Project 1 is to understand patterns and content of displayed health and risk behavior on social media that is created by, and consumed by, adolescents. We will determine connections between three key concepts through our Specific Aims, including: 1) what adolescents display on TDM about their own health and risk behaviors via self-generated content, 2) the displayed TDM content adolescents are exposed to in real-time about health and risk behaviors, and 3) adolescents’ self-reported health and risk behavior attitudes, social norms intentions and actions. Our third aim will assess neural processes underlying how created and consumed TDM content is processed and associated with health and risk behavior. The PI, Co-I and consultant on this Project bring over a decade of work in the area of adolescent behaviors displayed on social media, including several NIH-funded studies in this area. Our preliminary data indicates that for older adolescents, self-generated risk behavior content on TDM closely aligns with self-reported behavior, and that Ecological Momentary Assessment (EMA) is feasible to use with adolescent populations to assess real-time TDM use and content exposure. This study will use a longitudinal study design, collecting data over 2 years. The shared participant pool for this P01 program will be leveraged to recruit the sample of 400 adolescents aged 13-15 years at enrollment. Data collection approaches will include social media observation of health and risk behaviors, including self-generated and other-generated. This social media observational data will be linked to self-report survey data including attitudes, social norms, intentions and behaviors. Moderators will include technology importance and parent involvement. Data collection will also include Ecological Momentary Assessment (EMA) to determine adolescents’ exposure to self-generated and other-generated content across TDM in real-time. Finally, investigators will utilize social media data during a fMRI scan to determine whether self-generated and other-generated content is processed differently. This project aligns with the current RFA as utilizes multi-level assessments of health and development, including real-time measures of TDM exposure.
