项目摘要

DESCRIPTION (provided by applicant): The effects of social relationships on health behavior change and management of chronic conditions has been well documented. Investigators from a variety of disciplines have attempted to understand and harness the role of these social ties in health promotion. Online communities, which digitize peer-to-peer communication, provide a unique opportunity to researchers to understand the mechanisms underlying human behavior change. The onset of digital communication platforms has led investigators to question the use of existing behavior change theories that were formulated in the context of face-to-face communication. Manifestations of socio-behavioral constructs in online communities are often embedded in the content of the messages exchanged by users. Most studies of online and offline social networks have not considered communication content of peer-to-peer interactions when attempting to discern the theoretical underpinnings of network influence. In the proposed research, we will develop a framework for the incorporation of message content into network-based models of social influence. While generally applicable, the methods will be developed based on communications among individuals attempting to quit smoking in an online community, QuitNet, the first online social network for smoking cessation. The methods will be extended to analyze communication among members managing chronic conditions on TreatmentDiaries, an online community where patients share their daily experiences of disease management. Combining qualitative methods with automated text analysis, our work will facilitate high-throughput empirical analysis of user communication in online social networks allowing the identification of emergent user needs and community culture. Temporal models that capture the evolution of cognitive factors pertinent to health behavior change and chronic disease management will be developed. Content-specific communication characteristics of network influence and dependencies will be studied by adapting affiliation exposure models and exponential random graph modeling techniques. This research proposal will result in 1) novel methods to incorporate communication content into network models of social influence to enhance our understanding of the theoretical roots of behavior change in digital communication platforms; 2) scalable techniques to model temporal changes and network dependencies of user interactions in terms of communication content and structure; and 3) new proposals for the development of digital interventions and technology features that harness social ties to support individuals engaging in health behavior change and chronic disease management.

描述（由应用程序提供）：社会关系对健康行为变化和慢性状况管理的影响已得到充分记录。来自各个学科的研究人员试图理解和利用这些社会联系在健康促进中的作用。数字化点对点交流的在线社区为研究人员提供了一个独特的机会，以了解人类行为改变的机制。数字通信平台的发作导致调查人员质疑在面对面交流中提出的现有行为改变理论的使用。在线社区中社会行为结构的表现通常嵌入用户交换的消息的内容中。在试图辨别网络影响的理论基础时，大多数在线和离线社交网络的研究都没有考虑对等互动的通信内容。在拟议的研究中，我们将开发一个将消息内容纳入基于网络的社会影响模型的框架。尽管通常适用，但这些方法将基于试图在在线社区中戒烟的个人之间的通信，Quitnet，这是第一个在线戒烟的在线社交网络。这些方法将扩展以分析管理慢性疾病的成员之间的沟通，这是一个在线社区，患者每天都有疾病管理的经验。将定性方法与自动文本分析相结合，我们的工作将促进对在线社交网络中用户沟通的高通量经验分析，从而可以识别出紧急的用户需求和社区文化。将开发与健康行为变化和慢性疾病管理有关的认知因素演变的时间模型。通过调整会员暴露模型和指数随机图建模技术，将研究网络影响和依赖关系的内容特定的通信特征。该研究建议将导致1）将通信内容纳入社会影响的网络模型，以增强我们对数字通信平台行为变化的理论根源的新方法； 2）根据通信内容和结构对用户交互的临时更改和网络依赖性建模的可扩展技术； 3）关于发展数字干预措施和技术特征的新建议，这些建议利用社会关系支持从事健康行为改变和慢性病管理的个人。
