REFINING BOOSTERS TO STRENGTHEN ONLINE COLLEGE STUDENT DRINKING INTERVENTIONS

项目总结/摘要 本申请是对指导研究科学家发展奖（K 01 AA 023849; PI：Braitman），由于当前的2019冠状病毒病（COVID- 19)流行病在最初的奖项下的研究活动包括一系列的四项研究，旨在完善 该方法，提高电脑干预后的电子助推器的效力。研究 目标包括：1a）审查关于减少危害战略的反馈是否加强了 在助推器电子邮件中单独提供个性化的规范性反馈（研究1a -完成），1b）检查个人 联系增强了收到的定制反馈（研究1b -完成），2）确定最佳交付时间 对于助推器（研究2 -正在进行中），3a）探索变化的社会机制（跨研究），3b）检查 干预加助推器在传递到现有社交网络时的效果（即，兄弟会/姐妹会; 研究3 -尚未开始），以及4）检查减少酒精使用的潜在调节剂和介质 和相关问题（跨研究）。结果将为R 01应用提供初步数据。之前 大流行停止后，序列中前两项研究的数据收集工作已经完成。数据收集 第三项研究即将开始。然而，所有涉及人类受试者的研究的现场数据收集 于二零二零年三月因疫情及相关社交距离而被主办机构暂停 协议.虽然我们已经使用虚拟协议恢复了研究2的数据收集（9个月后 暂停），由于对社会饮酒的关注，很难审查项目目标。这导致了许多 比以前的研究慢。额外供资的年份将允许最后评估窗口， 研究2（9个月随访和数据分析）以及研究3的所有活动。预计的时间轴， 完成所有最初提出的研究活动（完成研究2并进行研究3），并交付所有 项目目标需要额外12个月的奖励，并需要额外的资金来维持PI的 机制所需的努力水平。为最初授予期确定的培训目标包括：1） 扩大和加强她新兴的成人酒精使用知识库，2）发展专业知识， 对大学饮酒者进行干预后加强和评估助推器，3）提高她的熟练程度 在社会网络分析中，4）通过二级数据分析和手稿来提高学术生产力 准备，和5）增加她的granularity，争取博士的指导。 Kelley，Cathy Lau-Barraco，Kayo Fujimoto，and Ken伦纳德.许多培训活动需要参加 因疫情而取消的现场研讨会和会议。虽然有些活动 由于流行病相关的日托，PI无法在2020年夏季/秋季参加任何在线过渡 关闭。然而，日托现在确实是开放的，PI计划参加会议和讲习班， 一个有资金的延长年（如果提供），以便所有培训活动只是推迟而不是取消。

PROJECT SUMMARY/ABSTRACT This application is for a supplement to the Mentored Research Scientist Development Award (K01 AA023849; PI: Braitman), directly necessary because of disruption due to the current coronavirus disease 2019 (COVID- 19) pandemic. Research activities under the original award included a series of four studies designed to refine the methodology, improve the efficacy of an electronic booster after computerized interventions. Research aims included to 1a) examine if feedback about harm reduction strategies strengthen the effects of personalized normative feedback alone in boosters emails (Study 1a - complete), 1b) examine if personal contact enhances the tailored feedback received (Study 1b - complete), 2) identify optimal timing of delivery for booster (Study 2 – in progress), 3a) explore social mechanisms of change (across studies), 3b) examine the effects of interventions-plus-boosters when delivered to existing social networks (i.e., fraternities/sororities; Study 3 – not yet started), and 4) examine potential moderators and mediators of reductions in alcohol use and related problems (across studies). Results will provide preliminary data for an R01 application. Prior to the pandemic shut down, data collection was complete for the first two studies in the sequence. Data collection for the third study was about to begin. However, on-site data collection for all studies involving human subjects was halted during March 2020 by the host institution due to the pandemic and related social distancing protocols. Although we have resumed data collection for Study 2 using virtual protocols (after a 9-month pause), examination of project aims is difficult due to the focus on social drinking. This has resulted in much slower enrollment than in previous studies. The extra funded year will allow for the final assessment window of Study 2 (9-month follow-up and data analysis) as well as all activities for Study 3. A projected timeline to complete all originally proposed research activities (complete Study 2 and conduct Study 3) and deliver on all project aims requires 12 additional months for the award, and additional funds are required to maintain the PI’s effort levels required by the mechanism. Training goals identified for the original award period included: 1) to broaden and strengthen her emerging adult alcohol use knowledge base, 2) to develop expertise in the enhancement and evaluation of boosters after interventions for college drinkers, 3) to increase her proficiency in Social Network Analysis, 4) to enhance scholarly productivity via secondary data analyses and manuscript preparation, and 5) to increase her grantsmanship, enlisting the mentorship of Drs. Kate Carey, Michelle Kelley, Cathy Lau-Barraco, Kayo Fujimoto, and Ken Leonard. Many of the training activities required attending in-person workshops and conferences which were cancelled due to the pandemic. Although some activities have transitioned online, the PI could not attend any in summer/fall of 2020 due to pandemic-related daycare closures. However, daycare is now reliably open and the PI plans to attend conferences and workshops during a funded extension year (if provided) so that all training activities are simply delayed and not cancelled.
