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.

项目概要/摘要 大麻（MJ）的使用在年轻人（YA）中很普遍，并且保持稳定或略有增加 (Schulenberg et al., 2019)，而 MJ 使用障碍则大幅增加 (Hasin et al., 2015)。 与后果有关，包括机动车事故（Volkow 等，2014）。 流程对于物质使用行为至关重要。一些青少年可能打算在某些日子减少其使用。 但几乎从未设法这样做，而其他年度可能打算减少其使用，并且通常 在何种情况下，青少年可以限制大麻的使用或后果。 心理状态和背景因素的变化尚不清楚，该应用程序解决了这个问题。 通过阐明青少年在日常生活中参与 MJ 特定自我调节过程的程度来消除差距 行为及其自然环境，并将识别与相关的心理和背景因素 MJ 特定的自我调节在不同日期和全天的变化。 年龄为 18-29 岁的青少年社区样本 (N = 200)，他们经常使用 MJ（过去 15 天或更长时间） 月），YA 可以通过多种方式规范或限制其 MJ 使用或后果，例如使用较小的 MJ。 因此，自我监管是在特定日期进行的，以尽量减少对其他责任的干扰。 最好将其视为一个动态过程，在不同天和一天中都会发生变化（例如， 渴望、焦虑、抑郁）和背景因素（例如饮酒和吸烟）可以部分解释什么时候 青少年或多或少可能会限制他们对 MJ 的使用，否则就会产生社交焦虑。 使用日常调查设计来了解大学生中 MJ 的使用情况（Buckner 等人，2012a，2012b；Phillips 等人， 2015）。青少年青少年中 MJ 的使用和/或后果也与抑郁症状和相关。 焦虑，尽管这种关联在女性中可能更为明显（Buckner 等人，2007 年；Wright 等人， 2016）该项目采用严格的生态瞬时评估（EMA）设计，其中评估报告 他们的行为以及相关的心理和背景因素连续两周每天 4 次（56 网络- 基于每人的调查），目的是：（1）检查 MJ 特定的自我之间的复杂关联。 (2) 检查日内和全天的监管流程和 MJ 使用/后果； 心理状态（例如渴望、焦虑）和背景因素（例如酒精）之间存在复杂的关联 和烟草使用）与特定于 MJ 的自我调节和使用超出预期的 MJ 相关；（3）评估 人与人之间以及日常层面的调节者，以确定对于谁以及何时关联可能更牢固。 所获得的知识可以为当前的自我调节理论提供信息，并可用于现有的干预措施中，以更好地 支持积极变革或讨论限制 MJ 使用的常见障碍，并用于 制定有针对性的干预策略，增强青少年青少年自我调节 MJ 使用的愿望。
