A Situational Examination of Neurocognition and Affect with Simultaneous Cannabis

同时大麻的神经认知和影响的情境检查

基本信息

项目摘要

DESCRIPTION (provided by applicant): The goal of the proposed training plan is to further develop the applicant's knowledge and research skills in the areas of substance use and neuropsychology and to integrate this with an understanding of ecological momentary assessment (EMA) and data analysis. The ultimate goal of the proposal is to conduct a dissertation project that will deepen the applicant's knowledge of research design and analytic issues addressing the topic of cognitive and affective situational factors surrounding cannabis and tobacco use and the field's knowledge of the momentary factors that contribute to conjoint cannabis and tobacco use among young adults. Given the skills that will be developed and the knowledge that will be gained, this project is a necessary step in achieving the applicant's career goal to pursue a faculty position in an academic setting where independent investigations can be conducted. The training plan proposed includes structured course work, regular sponsor meetings, experience with EMA data collection and analysis, and professional development activities. The proposed research furthers this training plan by examining the conjoint effects of simultaneous cannabis and tobacco use on neurocognitive, affective and behavioral outcomes in young adult tobacco users. The motivation for examining this particular drug combination comes from the increasing number of young people reporting combined use of cannabis and tobacco, the health consequences associated with conjoint use (e.g., greater dependence symptoms, fewer successful quit attempts), and the limited number of investigations examining the mechanisms that maintain simultaneous use. Given that young adults are highly influenced by contextual variables, EMA techniques are an optimal method for assessing the potential neurocognitive and affective factors that reinforce conjoint use. The specific aims of this study are: 1) to examine the effects of simultaneous use of cannabis and tobacco on momentary levels of neurocognitive functioning, namely changes in working memory and to compare these effects to the effects of cannabis and tobacco alone; 2) to examine the effects of simultaneous use on momentary changes in affect and subjective cannabis intoxication and to compare these effects to the effects of cannabis and tobacco alone; and 3) to examine the link between momentary changes in neurocognition, affect and subjective intoxication on behavioral outcomes (e.g., dependence and problematic use). Data will be collected from 325 young adults currently enrolled in a large, ongoing longitudinal investigation of the social and emotional contexts of young adult tobacco use. Mentorship for this project will be provided by experts in the areas of tobacco use and EMA methodology (Dr. Robin Mermelstein), cannabis use and the neuropsychology of addiction (Dr. Raul Gonzalez), and hierarchical longitudinal data analysis (Dr. Robin Mermelstein and Dr. Donald Hedeker). This area of research is in its nascent stages, and this study will be one of the first to examine conjoint effects of cannabis and tobacco as well as to integrate neurocognitive and EMA measures to the study of this understudied phenomenon. Not only will the proposed plan be instrumental in propelling the applicant's career forward, but also promises to yield results that will be directly applicable to the development of prevention and cessation efforts for young adult tobacco users who also use cannabis. PUBLIC HEALTH RELEVANCE: Tobacco use continues to be a major public health problem among young adults. A large percentage of young adult tobacco users also engage in simultaneous cannabis use, both of which are linked with a host of negative health consequences. This project will serve to delineate the mechanisms that reinforce this conjoint use. A better understanding of the situational correlates and consequences of simultaneous cannabis and tobacco use will inform the creation of more targeted prevention and cessation efforts for the young adults who use both cannabis and tobacco.
描述(由申请人提供):拟议培训计划的目标是进一步发展申请人在物质使用和神经心理学领域的知识和研究技能,并将其与对生态瞬时评估(EMA)和数据分析的理解相结合。该提案的最终目标是进行一个论文项目,将加深申请人对研究设计和分析问题的了解,这些问题涉及大麻和烟草使用周围的认知和情感情境因素以及该领域对年轻人联合使用大麻和烟草的瞬时因素的了解。鉴于将开发的技能和将获得的知识,该项目是实现申请人的职业目标的必要步骤,以在可以进行独立调查的学术环境中追求教师职位。拟定的培训计划包括结构化课程、定期申办者会议、EMA数据收集和分析经验以及专业发展活动。拟议的研究通过检查大麻和烟草同时使用对年轻成年烟草使用者的神经认知,情感和行为结果的联合影响,进一步推动了这一培训计划。审查这种特定药物组合的动机来自越来越多的年轻人报告大麻和烟草的混合使用,与混合使用有关的健康后果(例如,更大的依赖症状,更少的成功戒烟尝试),以及有限数量的调查,检查机制,保持同时使用。鉴于年轻人高度受上下文变量的影响,EMA技术是评估潜在的神经认知和情感因素,加强联合使用的最佳方法。本研究的具体目的是:1)检查同时使用大麻和烟草对神经认知功能瞬时水平的影响,即工作记忆的变化,并将这些影响与大麻和烟草单独的影响进行比较;(二)检查同时使用对情感和主观大麻中毒的瞬间变化的影响,并将这些影响与大麻的影响进行比较,烟草单独;以及3)检查神经认知、情感和主观中毒对行为结果的瞬间变化之间的联系(例如,依赖性和使用问题)。数据将从325名年轻人中收集,这些年轻人目前正在进行一项关于年轻人烟草使用的社会和情感背景的大型纵向调查。该项目的指导将由烟草使用和EMA方法(Robin Mermelstein博士)、大麻使用和成瘾神经心理学(Raul Gonzalez博士)以及分层纵向数据分析(Robin Mermelstein博士和Donald Hedeker博士)领域的专家提供。这一领域的研究正处于起步阶段,这项研究将是第一个研究大麻和烟草的联合作用,以及将神经认知和EMA措施整合到这一研究不足的现象的研究中。拟议的计划不仅有助于推动申请人的职业发展,而且还有望产生直接适用于为同时使用大麻的年轻成年烟草使用者开展预防和戒烟工作的结果。 公共卫生相关性:烟草使用仍然是年轻人的主要公共卫生问题。很大比例的年轻成人烟草使用者还同时使用大麻,这两者都与一系列负面健康后果有关。该项目将有助于阐明加强这种联合使用的机制。更好地了解大麻和烟草同时使用的情况相关性和后果,将有助于为使用大麻和烟草的年轻人制定更有针对性的预防和戒烟工作。
