项目摘要
PROJECT SUMMARY
Cannabis use disorder (CUD) is a significant public health concern with origins in adolescence. Cannabis use
escalates during the teenage years, and early cannabis use predicts the development of later problems. Leading
etiological theories suggest that repeated cannabis use as the brain develops produces changes in reward
systems. Over time, these instrumental brain changes alter cannabis effects and increase the incentive salience
of cannabis cues, ultimately conferring risk for CUD. This longitudinal study pairs ecological momentary
assessment (EMA) in the natural environment and a gold-standard human laboratory (HLAB) paradigm to
monitor changes in subjective cannabis effects, cue reactivity, and CUD symptoms across the formative
adolescent years. Leveraging smartphone (EMA) reports in natural settings allows for studying adolescents’
reactions to the typically higher potency THC products and varied formulations (e.g., oils, edibles) favored by
teenagers. The use of an accelerated longitudinal design allows for charting development from ages 13 to 19
through multicohort assessments completed in a shorter timeframe. We aim to recruit 224 adolescents (ages 13
to 16 at study outset, n = 56 per age cohort) who endorse cannabis use in the past month. Adolescents will
complete a baseline HLAB protocol with follow-ups at 1, 2, and 3 years. Each yearly assessment point will also
include a 28-day measurement burst of EMA in daily life. Multiple domain latent growth curve modeling will: (Aim
1) characterize age-related changes in sensitivity to rewarding cannabis effects over adolescence (ages 13 to
19); (Aim 2) test prospective relations of CUD symptom progression with change in sensitivity to rewarding
cannabis effects; and (Aim 3) test prospective relations of CUD progression with responses to cannabis cues in
the natural environment and HLAB. The proposed longitudinal study extends the investigative team’s prior
research showing cross-sectional associations of CUD severity with subjective cannabis effects and cue
reactivity among adolescents. Our proposal is highly innovative, as well-studied etiological CUD constructs are
assessed across adolescence in real-world and laboratory settings using well-operationalized, multidimensional
assessments. Further, disaggregating individual differences in change from overall age trends through an
accelerated longitudinal design is a sensitive approach that is distinctively innovative. Our proposal addresses a
key priority identified by the NIDA Epidemiology Research Branch by efficiently combining the advantages of
longitudinal research with behavioral and laboratory-based measures to inform understanding of CUD etiology
(NOT-DA-19-066). This proposal will support efforts to prevent the progression of an incubating or emerging
CUD by enhancing scientific understanding of the trajectory to more severe harms. Providing new empirical
evidence of malleable processes that can serve as targets of preventative interventions has power to reduce the
magnitude of societal ramifications of CUD.
项目总结
大麻使用障碍(CUD)是一个重大的公共卫生问题,起源于青春期。吸食大麻
在青少年时期,吸食大麻的风险逐渐上升,早期吸食大麻预示着以后的问题的发展。先导
病因学理论表明,随着大脑发育,重复使用大麻会导致奖赏的变化
系统。随着时间的推移,这些工具性的大脑变化改变了大麻的影响,并增加了激励的显著程度
大麻线索,最终给CUD带来风险。这项纵向研究配对了生态瞬间
自然环境评估(EMA)和黄金标准的人类实验室(HLAB)范例
监测整个形成期的主观大麻效应、线索反应性和CUD症状的变化

通过在较短的时间内完成多队列评估。我们的目标是招募224名青少年(13岁

完成基线HLAB方案,并在1年、2年和3年进行跟踪。每个年度评估点还将
包括日常生活中EMA的28天测量突发。多域潜在增长曲线建模将:(AIM
1)描述青春期(13岁至20岁)对奖励大麻效果的敏感性与年龄相关的变化

大麻效应;以及(目标3)测试CUD进展与对大麻线索的反应的预期关系
自然环境和HLAB。拟议的纵向研究扩展了调查小组之前的
研究表明CUD严重程度与主观大麻效果和线索的横截面关联
青少年的反应性。我们的建议是高度创新的,因为经过充分研究的病因学CUD结构是
在现实世界和实验室环境中评估青春期,使用可操作性好的多维

加速纵向设计是一种敏感的方法,具有明显的创新性。我们的建议针对的是
NIDA流行病学研究分部通过有效结合以下优势确定的关键优先事项
以行为和实验室为基础的纵向研究,以了解CUD病因学

通过加强对走向更严重危害的轨迹的科学理解,消除对妇女的歧视。提供新的经验
可以作为预防性干预目标的可塑性过程的证据有能力减少
CUD的社会影响的大小。
