DESCRIPTION (provided by applicant): Currently, marijuana (MJ) is the most popular illicit drug, with prevalence studies indicating increasing use among young adults (Johnston et al., 2011). Even so, there are few effective interventions to help MJ users reduce their intake to avoid negative consequences, including MJ dependence. In this revised application, we propose a Stage 1 efficacy study to develop and initially test an innovative intervention to reduce MJ use among young adults who regularly use MJ (> 3 episodes/week). The intervention includes elements from the Marijuana Check-Up (MCU; Stephens et al., 2007), a MI-based brief intervention that has shown promise for reducing MJ use. It also incorporates findings from our ongoing research, which suggest that exercise/physical activity (PA) has potential as a positive alternative to MJ use. Our research also has shown that short (i.e., 10 minute) bouts of moderate or intense exercise reduce craving/urges to use MJ. Exercise interventions have successfully reduced use of licit substances, such as tobacco (e.g., Marcus et al., 2005) and alcohol (e.g., Brown et al., 2009), but have not been adequately tested for MJ use. The two aims of this R34 application are: 1) To develop an intervention that consists of four, 60-minute, in-person sessions composed of MCU content (e.g., personalized feedback, MI) as well as a smartphone application (app) that promotes exercise/physical activity (EA) as an alternative to MJ use. The EA, which will be designed to specifically appeal to young adults, will provide a readily-accessible, flexible, and convenient platform for personalized information and reminders that promote exercise/PA as a positive alternative to MJ use in ongoing daily life. 2) To conduct a pilot/efficacy study of the 4-week MCU+EA intervention vs. a MCU-only control condition. We will use urn randomization to assign emerging/young-adult MJ users (N = 40) to the two conditions. During the 1-week baseline, 4-week intervention phase, and 1-, 3-, and 6-month follow-ups, all participants will use the smartphone app to provide real-time data on MJ-related variables and wear accelerometers to provide PA data. Multilevel modeling will be used to test our hypothesis that the MCU+EA intervention, compared to MCU-only control, will produce greater decreases in quantity and frequency of MJ use (and related MJ problems) at post-intervention and at each follow-up. Multilevel modeling also will be used to explore the real-time data to examine the role of variables such as urge/craving for MJ, social factors, and dosage of PA in the reduction of the quantity and frequency of MJ use. This Stage 1 study is unique and innovative in its development and use of a smartphone app to promote and evaluate exercise/PA as a positive alternative to MJ use in daily life. It includes cutting-edge technology (e.g., accelerometers, smartphone app) for real-time assessments. This research will make significant contributions to the limited knowledge of exercise/PA as a strategy for reducing MJ use and related problems among emerging and young adults.

描述（由申请人提供）：目前，大麻（MJ）是最受欢迎的非法药物，患病率研究表明在年轻人中使用越来越多（Johnston等，2011）。即便如此，很少有有效的干预措施可以帮助MJ用户减少其摄入量以避免负面后果，包括MJ依赖。在此修订后的应用中，我们提出了一项1阶段效力研究，以开发并最初测试一种创新的干预措施，以减少定期使用MJ的年轻人（> 3集/周）的MJ使用。该干预措施包括大麻检查的元素（MCU； Stephens等，2007），这是一种基于MI的简短干预措施，显示出减少MJ使用的希望。它还结合了我们正在进行的研究中的发现，这表明运动/体育锻炼（PA）具有潜力作为MJ使用的积极替代方案。我们的研究还表明，中度或激烈的运动的简短（即10分钟）回合减少了使用MJ的渴望/冲动。运动干预措施已成功地减少了烟草（例如Marcus等，2005）和酒精（例如Brown等，2009）的使用，但尚未对MJ使用进行充分的测试。该R34应用程序的两个目的是：1）开发由四个，60分钟的，面对面的会议组成的干预措施，由MCU内容（例如个性化反馈，MI）以及智能手机应用程序（APP）组成，以促进运动/体育活动（EA）作为MJ使用的替代方法。 EA将旨在专门吸引年轻人，将为个性化信息和提醒提供一个易于访问，灵活且方便的平台，以促进锻炼/PA，作为在日常生活中使用MJ的积极替代方案。 2）进行为期4周的MCU+EA干预措施与仅MCU控制条件的试验/功效研究。我们将使用urn随机化将新兴/年轻成人的MJ用户（n = 40）分配给两个条件。在为期1周的基线，4周的干预阶段以及1个月，3个月和6个月的随访中，所有参与者将使用智能手机应用程序提供有关MJ相关变量的实时数据，并磨损加速度计以提供PA数据。多级建模将用于测试我们的假设，即与仅MCU控制相比，MCU+EA干预将在干预后和每次随访中产生更大的MJ使用（以及相关MJ问题）的数量和频率（以及相关的MJ问题）。多级建模还将用于探索实时数据，以检查变量的作用，例如MJ的急需/渴望，社会因素和PA剂量在减少MJ使用的数量和频率中。这一阶段1的研究在开发和使用智能手机应用程序方面具有独特性和创新性，以促进和评估运动/PA，作为日常生活中MJ使用的积极替代方案。它包括用于实时评估的尖端技术（例如，加速度计，智能手机应用程序）。这项研究将为有限的运动/PA知识做出重大贡献，作为减少新兴和年轻人中MJ使用以及相关问题的策略。
