Project Summary Cannabis use poses an important public health problem among emerging adults (EAs), given increasing perceived acceptability and prevalence of cannabis use, combined with state-level legislation resulting in increased access to legal cannabis. Although there are some promising cannabis intervention approaches for college EAs, about half of EAs are not in college. Further, these interventions were developed prior to the legalization of recreational cannabis use in 8 U.S. states and the District of Columbia. In recent years engagement with social media has dramatically increased, with the majority of EAs accessing social media platforms multiple times per day, exposing EAs to online peer influences, which are generally not addressed in existing intervention programs. High levels of engagement with social media content provide a dynamic platform to engage EAs in interventions for cannabis risk reduction. The specific aims of the proposed study are to: 1) iteratively develop and focus test an 8-week social media-based intervention for cannabis use among EAs and 2) test the preliminary efficacy of the intervention versus a 8-week control condition on cannabis- related outcomes. We will use an iterative process to develop a social media-delivered 8-week “secret” group intervention (i.e., other “friends” on the site cannot see membership or content) delivered by peer coaches using the most popular social media platform among EAs (i.e., Facebook), with content pushed across other platforms allowing private messaging (e.g., Twitter, Snapchat). Based on prior work, we will develop engaging, user-generated content using crowdsourcing via Amazon's Mechanical Turk, followed by iterative focus testing with participants from states where recreational cannabis is legal and where it remains illegal. The intervention will harness peers as coaches to be positive influences, which is scalable given the availability of student trainees and will focus on “up-stream” factors for cannabis use such as motives for use (e.g., stress/coping, social), blending evidenced based approaches for cannabis risk reduction (e.g., motivational interviewing, cognitive behavioral therapy strategies). The developed intervention will be tested in a pilot randomized controlled trial versus an attention-placebo control (8-week social media news condition) among 18-25 year-old EAs who regularly use cannabis (i.e., at least weekly). Groups will be conducted separately for EAs residing in states with/without legal recreational cannabis. Outcomes will be measured at a 3-month post-test and 6- month follow-up, with biological verification of drug use. As opposed to static web-based interventions with limited shelf-life, the development of an adaptable, scalable and efficacious intervention for cannabis use among EAs is a critical next step in public health efforts to reduce cannabis use/consequences. This study could have significant impact by altering the cannabis use trajectories of EAs, preventing health and social consequences and the development of cannabis use disorders, as well as informing future social media interventions for behavioral health.

项目概要 鉴于越来越多的人使用大麻，对新兴成年人 (EA) 来说是一个重要的公共卫生问题 大麻使用的可接受性和流行程度，加上州一级的立法，导致 尽管有一些有前途的大麻干预方法，但增加了获得合法大麻的机会。 大学 EA，大约一半的 EA 不在大学此外，这些干预措施是在大学之前制定的。 近年来，美国 8 个州和哥伦比亚特区将娱乐性大麻合法化。 社交媒体的参与度急剧增加，大多数 EA 都会访问社交媒体 每天多次访问平台，使 EA 受到在线同行的影响，而这些影响通常不会在 现有干预计划的高水平参与社交媒体内容提供了动态。 拟议研究的具体目标。 的目标是： 1) 迭代开发并重点测试为期 8 周的基于社交媒体的大麻使用干预措施 EA 和 2) 测试干预措施与大麻 8 周控制条件的初步效果- 我们将使用迭代过程来开发一个社交媒体交付的为期 8 周的“秘密”小组。 由同伴教练进行干预（即网站上的其他“朋友”无法看到会员资格或内容） 使用 EA 中最流行的社交媒体平台（即 Facebook），将内容推送到其他平台 基于之前的工作，我们将开发允许私人消息传递的平台（例如 Twitter、Snapchat）。 通过亚马逊的 Mechanical Turk 使用众包生成用户生成的内容，然后进行迭代焦点测试 参与者来自休闲大麻合法但仍非法的州。 将利用同伴作为教练来产生积极的影响，考虑到学生的可用性，这是可扩展的 学员并将重点关注大麻使用的“上游”因素，例如使用动机（例如压力/应对、 社会），混合减少大麻风险的循证方法（例如动机访谈， 认知行为治疗策略）。所开发的干预措施将在随机试点中进行测试。 在 18-25 岁人群中进行的对照试验与注意力安慰剂对照（8 周社交媒体新闻条件） 经常使用大麻（即至少每周一次）的 EA 将对居住在该地区的 EA 进行单独分组。 有/没有合法娱乐大麻的州将在测试后 3 个月和 6 个月后测量结果。 一个月的随访，对药物使用进行生物验证，而不是基于静态网络的干预措施。 有限的保质期，开发适应性强、可扩展且有效的大麻使用干预措施 这项研究是公共卫生努力减少大麻使用/后果的关键下一步。 可能会通过改变 EA 的大麻使用轨迹、预防健康和社会问题产生重大影响 大麻使用障碍的后果和发展，以及告知未来的社交媒体 行为健康干预措施。
