PROJECT SUMMARY/ABSTRACT Marijuana (MJ) use is prevalent among young adults (YAs) and has remained stable or slightly increased (Schulenberg et al., 2019), while MJ use disorders have risen considerably (Hasin et al., 2015). MJ use has been linked to consequences, including motor vehicle accidents (Volkow et al., 2014). Self-regulation processes are central to substance use behaviors. Some YAs may intend to reduce their use on certain days but almost never manage to do so, while other YAs may intend to reduce their use and are generally successful. The circumstances under which YAs may limit their marijuana use or consequences in response to changes in psychological states and contextual factors is not well understood. This application addresses this gap by elucidating the extent to which YAs engage in MJ-specific self-regulation processes in their everyday behavior and their natural environment and will identify psychological and contextual factors associated with variability in MJ-specific self-regulation both across days and throughout the day. This project will recruit a community sample of YAs ages 18-29 years (N = 200), who use MJ regularly (15 or more days in the past month). YAs may regulate or limit their MJ use or consequences in a variety of ways, such as using smaller quantities on a given day to minimize interference with other responsibilities. Accordingly, self-regulation is best viewed as a dynamic process that varies both across days and throughout the day. Psychological (e.g., craving, anxiety, depression) and contextual (e.g., alcohol and tobacco use) factors may partly explain when YAs are more or less likely to limit their MJ use or consequences. Craving and social anxiety have been linked to MJ use among college students using daily survey designs (Buckner et al., 2012a, 2012b; Phillips et al., 2015). MJ use and/or consequences among YAs have also been associated with depressive symptoms and anxiety, although associations may be more pronounced among females (Buckner et al. 2007; Wright et al., 2016). This project uses a rigorous ecological momentary assessment (EMA) design in which YAs report on their behavior and related psychological and contextual factors 4x/day for two consecutive weeks (56 web- based surveys per person). The aims are to: (1) examine complex associations between MJ-specific self- regulation processes and MJ use/consequences both across days and throughout the day; (2) examine complex associations among psychological states (e.g., craving, anxiety) and contextual factors (e.g., alcohol and tobacco use) in relation to MJ-specific self-regulation and using more MJ than intended; and (3) evaluate between-person and daily-level moderators to determine for whom and when associations may be stronger. The knowledge gained can inform current self-regulation theories, be used in existing interventions to better support active change or discuss commonly encountered obstacles to limiting one’s MJ use, and be used to develop targeted intervention strategies that enhance YAs’ desire to self-regulate their MJ use.

项目摘要/摘要 大麻(MJ)的使用在年轻人(YA)中很普遍，并保持稳定或略有增加 (Schulenberg等人，2019年)，而MJ使用障碍大幅上升(Hasin等人，2015年)。MJ的使用有 与后果有关，包括机动车事故(Volkow等人，2014年)。自律 过程是物质使用行为的核心。一些YA可能打算在某些日子减少使用它们 但几乎从来没有做到这一点，而其他YA可能打算减少它们的使用，通常 成功。在什么情况下，亚人可以限制其大麻的使用或后果，以回应 心理状态和背景因素的变化还没有得到很好的理解。这个应用程序解决了这个问题 GAP通过阐明YA在日常生活中参与MJ特有的自我调节过程的程度 行为及其自然环境，并将确定与以下方面相关的心理和背景因素 MJ特定的自我调节在一天和一天中的可变性。该项目将招聘一名 18-29岁(N=200)经常使用MJ(过去15天或更长时间)的YAS社区样本 月)。YAS可以通过各种方式来管理或限制其MJ的使用或后果，例如使用较小的 某一天的数量，以最大限度地减少对其他职责的干扰。因此，自律是 最好将其视为一个动态的过程，在一天和一天中都不同。心理(例如， 欲望、焦虑、抑郁)和环境因素(例如，饮酒和吸烟)可以部分解释什么时候 YA或多或少可能会限制他们对MJ的使用或后果。渴望和社交焦虑被联系在一起 使用日常调查设计在大学生中使用MJ(Buckner等人，2012a，2012b；Phillips等人， 2015年)。YA中MJ的使用和/或后果也与抑郁症状和 焦虑，尽管这种联系在女性中可能更明显(Buckner等人。2007年；Wright等人， 2016)。该项目使用严格的生态瞬时评估(EMA)设计，在该设计中，YAS报告 他们的行为和相关的心理和背景因素连续两周每天4次(56个网络- 基于每人的调查)。其目的是：(1)检查MJ-特定自我-之间的复杂联系 每天和全天的监管过程和MJ的使用/后果；(2)检查 心理状态(如渴望、焦虑)和环境因素(如酒精)之间的复杂联系 和烟草使用)与MJ特定的自我调节和使用比预期更多的MJ有关；以及(3)评估 人与日常级别的主持人之间，以确定谁以及何时可能会有更强的关联性。 所获得的知识可以为当前的自我调节理论提供参考，用于现有的干预措施，以更好地 支持积极改变或讨论限制某人MJ使用的常见障碍，并被用来 制定有针对性的干预策略，增强YAS自我调节MJ使用的愿望。
