PROJECT SUMMARY/ABSTRACT Young adulthood is associated with increased alcohol and marijuana use compared to other developmental periods (Schulenberg et al., 2019). Alcohol and marijuana use place individuals at high risk for acute and long- term negative consequences (Volkow et al., 2014; White & Hingson, 2014). SAM use is associated with increased risk for consequences, compared to marijuana use alone or CAM use (Lipperman-Kreda et al., 2017). In the proposed research, all participants will be current alcohol and marijuana users allowing us to consider Concurrent Alcohol and Marijuana (CAM) use and Simultaneous Alcohol and Marijuana (SAM) use. In this application, CAM use refers to use of both substances on the same day, but not so their effects overlap, whereas SAM use refers to use of alcohol and marijuana at the same time so that their effects overlap. Despite the relatively large cross-sectional and longitudinal literature on protective behavioral strategies (PBS; Pearson, 2013), little is known about why young adults choose to use PBS on specific occasions or why young adults might use PBS differently across occasions. Moreover, findings have been mixed for PBS use as a mediator of intervention effects (Reid & Carey, 2015). Thus, there is significant room for improvement in the conceptualization, application, and understanding of alcohol and marijuana PBS. The proposed research is needed to determine motivations, or reasons, for when, why, and how young adults may or may not use PBS in a quality manner when using alcohol and/or marijuana. This gained knowledge can be used to enhance intervention efficacy by addressing these motivations in intervention content delivered across days. Research has yet to examine how alcohol and marijuana PBS use on a given day relates to an individual’s use of alcohol or marijuana alone in comparison to CAM or SAM days. The current study has potential to contribute significantly to the literature as it will allow for a fine-grained examination of how alcohol and marijuana PBS use relate to alcohol, marijuana, and CAM/SAM use at the daily level. Taken together, the proposed study will fill these gaps by utilizing online focus groups and cognitive interviews to identify “why” young adults use or do not use PBS (for marijuana or alcohol) as well as to examine quality of PBS use and if quality differs on alcohol-only days, CAM days, or SAM days (Aim 1). Findings from Aim 1 will inform a pilot study (Aim 2) testing a newly developed online and text message alcohol and marijuana PBS intervention among alcohol and marijuana users age 18-24. The pilot study includes event-level data collection over 8 weekends to determine whether alcohol or marijuana PBS are as effective at reducing use or consequences when CAM or SAM use occurs, compared to using alcohol alone. In the pilot study (Stage I; N=200), we will establish acceptability, feasibility, and preliminary effect sizes to determine readiness for a full-scale efficacy trial. Because the proposed intervention will be designed to target PBS for alcohol and marijuana use the intervention will be relevant to a wider group of at-risk young adults.

项目总结/摘要 与其他发育阶段相比，年轻人与酒精和大麻的使用增加有关。 周期（Schulenberg等人，2019年）。酒精和大麻的使用使个人处于急性和长期- 长期的负面后果（Escherow等人，2014;白色和Hingson，2014）。SAM的使用与 与单独使用大麻或使用CAM相比，后果风险增加（Lipperman-Kreda等人， 2017年）。在拟议的研究中，所有参与者都将是目前的酒精和大麻使用者，这使我们能够 考虑同时使用酒精和维生素C（CAM）和同时使用酒精和维生素C（SAM）。在 在本申请中，CAM使用是指在同一天使用两种物质，但不使它们的效果重叠， 而SAM的使用是指同时使用酒精和大麻，使其效果重叠。尽管 关于保护性行为策略的相对较大的横向和纵向文献（PBS; Pearson，2013），很少有人知道为什么年轻人选择在特定场合使用PBS，或者为什么年轻人 成年人可能会在不同的场合使用PBS。此外，PBS作为一种 干预效应的中介（Reid & Carey，2015）。因此，存在显著的改进空间， 概念化，应用和酒精和大麻PBS的理解。拟议的研究是 需要确定动机，或原因，什么时候，为什么，以及如何年轻人可能会或可能不会使用PBS 在使用酒精和/或大麻时，这些知识可以用来提高 通过在干预内容中解决这些动机来提高干预效果。研究 还没有研究酒精和大麻PBS在特定的一天使用如何与个人的酒精使用有关 或大麻单独与CAM或SAM天相比。目前的研究有可能有助于 重要的文献，因为它将允许一个细粒度的检查如何酒精和大麻PBS 使用与酒精、大麻和CAM/SAM的日常使用有关。总的来说，拟议的研究将 通过利用在线焦点小组和认知访谈来填补这些空白，以确定年轻人使用或 不使用PBS（用于大麻或酒精），以及检查PBS使用的质量，如果质量不同， 仅含酒精天数、CAM天数或SAM天数（目标1）。目标1的结果将为试点研究提供信息（目标2） 测试一种新开发的在线和短信酒精和大麻PBS干预酒精 和18-24岁的大麻使用者。试点研究包括在8个周末收集事件级数据， 确定酒精或大麻PBS是否在减少使用或后果方面同样有效， 与单独使用酒精相比，SAM的使用发生。在先导研究（第一阶段; N=200）中，我们将建立 可接受性、可行性和初步效应量，以确定全面疗效试验的准备情况。 由于拟议的干预措施将被设计为针对PBS的酒精和大麻使用， 干预措施将与更广泛的高危青年群体相关。
