Characterizing alcohol use disorder recovery-related exposures on Twitter: Content, cluster, and network analysis

项目总结/摘要 K01的首要目标是支持Alex Russell博士的培训。他的目标是成为 独立的酒精使用障碍（AUD）恢复研究人员，具有如何利用社交媒体的专业知识 以新颖和创新的方式加强AUD治疗和康复结果的平台。为了帮助实现这一点 目标，候选人提出了一个原始的指导研究，重点是发展科学知识 关于AUD和与恢复相关的社交媒体曝光，以定义基于社交媒体的突出 澳元复苏的障碍和促进因素，从而为基于叙事的社交媒体干预提供信息 旨在提高AUD治疗和恢复结果。在目标1中，我们将描述澳元和复苏的特征- 通过使用无人监督的机器进行定性内容分析， 学习和归纳编码方法-查明恢复的潜在障碍/促进因素 Twitter.在aim2中，我们将使用潜在类分析来识别 tweets推文，over and above以上individual个别themes主题.我们还将确定不同的职位特征（例如，格式化， 源）和内容群集主题与用户参与相关联（即，喜欢，转发）。在目标3中， 网络分析将用于检查障碍/促进者相关职位的网络结构， Twitter上关于澳元和复苏的重要意见领袖和话题（以后干预的目标）， 确定帖子的网络位置如何随帖子特性而变化（例如，格式、来源）和领域 澳元复苏的障碍和促进因素。这种指导性研究旨在促进培训，以帮助候选人 发展专业知识，建立独立的研究生涯。更具体地说，罗素博士的导师团队 （菲利普·梅西、布兰登·伯格曼、约翰·凯利、达纳·利特和布赖恩·普里马克）将促进他的科学发展 在以下领域：1）AUD恢复科学（成瘾治疗和恢复，恢复机制- 相关的行为改变，数字恢复支持服务）; 2）基于社会媒体的研究方法（理论， 数据收集、测量、分析和解释）; 3）潜在类别分析; 4）社会网络分析; （5）职业发展与晋升。此外，罗素博士的培训计划将补充实际的 正式课程和讲习班的经验和指导，以及研究的传播 会议上的发现。他的职业目标符合NIAAA的重点：a）识别和 制定战略，减少阻碍人们饮酒的个人和组织障碍 寻求和接受适当护理的障碍，B）研究潜在的重要恢复机制 在处于危险的发展阶段，c）开发和测试可以加强传播的方法， 并在全方位服务中采用循证酒精相关治疗实践， 风险，有害的，和依赖饮酒者，和d）创新行为策略的发展，以促进 饮酒相关行为改变（PA-15 - 299）。

PROJECT SUMMARY/ABSTRACT The overarching goal of this K01 is to support the training of Dr. Alex Russell. His goal is to become an independent alcohol use disorder (AUD) recovery researcher with expertise in how to leverage social media platforms to enhance AUD treatment and recovery outcomes in novel and innovative ways. To help achieve this goal, the candidate proposes an original mentored research study focused on developing scientific knowledge about AUD and recovery-related social media exposures in order to define prominent social-media based barriers to and facilitators of AUD recovery, and thereby informing narrative-based social media interventions designed to enhance AUD treatment and recovery outcomes. In aim 1, we will characterize AUD and recovery- related exposures on Twitter by conducting a qualitative content analysis using an unsupervised machine learning and inductive coding approach – identifying potential barriers to/facilitators of recovery present on Twitter. In aim 2, we will use latent class analysis to identify underlying content similarities between clusters of tweets, over and above individual themes. We will also determine how varying post characteristics (e.g., format, source) and content cluster themes are associated with user engagement (i.e., likes, retweets). In aim 3, social network analysis will be used to examine the network structure of barriers/facilitators-related posts, identifying important opinion-leaders and topics about AUD and recovery on Twitter (targets for later intervention) and to determine how network position of posts varies by post characteristics (e.g., format, source) and domains of AUD recovery barriers and facilitators. This mentored study is intended to facilitate training to help the candidate develop the expertise to build an independent research career. More specifically, Dr. Russell’s mentorship team (Philip Massey, Brandon Bergman, John Kelly, Dana Litt, and Brian Primack) will foster his scientific development in the following areas: 1) AUD recovery science (addiction treatment and recovery, mechanisms of recovery- related behavior change, digital recovery support services); 2) social media-based research methods (theory, data collection, measurement, analyses, and interpretation); 3) latent class analysis; 4) social network analysis; and 5) career development and grantsmanship. Additionally, Dr. Russell’s training plan will supplement practical experiences and mentorship with formal coursework and workshop attendance, and dissemination of research findings at conferences. His career goals are in line with NIAAA’s emphases on a) the identification and development of strategies to reduce personal and organizational barriers that prevent people with alcohol use disorders from seeking and receiving appropriate care, b) the study of potentially vital recovery mechanisms during an at-risk developmental stage, c) the development and testing of methods that can enhance the diffusion and adoption of evidence-based alcohol-related treatment practices across the full spectrum of services for at- risk, harmful, and dependent drinkers, and d) the development of innovative behavioral strategies to promote drinking-related behavior change (PA-15-299).
