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）在年轻人（YA）中普遍存在，并且保持稳定或略有增加 （Schulenberg等，2019），而MJ使用障碍保守地增加（Hasin等，2015）。 MJ使用有 我们与后果有关，包括汽车事故（Volkow等，2014）。自我调节 过程是物质使用行为的核心。某些YA可能打算在某些日子减少其使用 但是几乎从来没有设法这样做，而其他YA可能打算减少其使用，并且通常是 成功的。 YAS可能会限制其大麻使用或后果的情况 心理状态和情境因素的变化尚不清楚。此应用程序解决了这个 通过阐明YA每天参与MJ特定自我调节过程的程度来差距 行为及其自然环境，并将确定与 整天和整天的MJ特异性自我调节的变异性。这个项目将招募 定期使用MJ（过去15天或以上）的18-29岁的YAS社区样本（n = 200） 月）。 YA可以以多种方式调节或限制其MJ使用或后果，例如使用较小 在给定日期的数量以最大程度地减少对其他责任的干扰。彼此之间，自我调节是 最好将视为在整天和整天各不相同的动态过程。心理学（例如 渴望，焦虑，抑郁）和上下文（例如酒精和烟草使用）可能部分解释 YA或多或少限制其MJ使用或后果。渴望和社交焦虑已经联系 使用日常调查设计在大学生中使用MJ（Buckner等，2012a，2012b; Phillips等，，，， 2015）。 MJ在YA中使用和/或后果也与抑郁症状和/或 焦虑，尽管女性之间的联系可能更为明显（Buckner等，2007； Wright等，，，，， 2016）。该项目使用严格的生态瞬时评估（EMA）设计，其中YAS报告了 他们的行为以及相关的心理和情境因素连续两周4倍/天（56个网络） 基于每人的调查）。目的是：（1）检查MJ特异性自我之间的复杂关联 整天和整天的监管过程和MJ使用/后果； （2）检查 心理状态之间的复杂关联（例如，渴望，动画）和上下文因素（例如酒精 与MJ特异性的自我调节有关，并使用比预期更多的MJ有关； （3）评估 人际关系和日常级别的主持人确定与谁和何时结合的人。 获得的知识可以告知当前的自我调节理论，可用于现有干预措施以改善 支持主动的变化或讨论通常遇到限制MJ使用的障碍，并用于 制定有针对性的干预策略，以增强Yas自我调节其MJ使用的愿望。
