项目摘要
PROJECT SUMMARY / ABSTRACT
Alcohol use disorder (AUD) is highly heterogeneous in that its symptoms are highly varied and, often, non-
overlapping across individuals. In theory, this phenotypic heterogeneity reflects the influence of multiple
underlying causes, or etiologic mechanisms. This etiologic complexity makes AUD treatment very challenging;
researchers have identified AUD’s etiologic complexity as the most critical barrier to progress in developing more
effective, personalized treatments. Addiction theorists have identified a set of alcohol addiction research domain
criteria (AARDoC) functional domains, believed to be important etiologic mechanisms for AUD. Yet, existing
models meant to link these mechanisms to AUD-related behaviors and symptoms fail to consider etiology.
Hence, many basic questions concerning the etiology of problematic drinking and AUD-related symptoms remain
unresolved. The proposed work aims to identify the prospective contributions of functional domain neuro-
behavioral indicators to the etiology of heavy drinking (HD) and AUD-related symptoms during adolescence and
emerging adulthood, the decade of development when HD and AUD-related symptoms are most prevalent. We
will enroll a target sample of 480 adolescents and emerging adults (160 in each of three partially overlapping
age cohorts [50% female], pre-screened for elevated HD risk) to participate in a prospective study using an
accelerated longitudinal design, which will allow us to characterize trajectories of alcohol involvement and AUD-
related symptoms over a 10-year period of development within a five-year study. We will use a neuroclinical
assessment approach to comprehensively characterize four functional domains—cognitive control/disinhibition
(DIS), reward sensitivity (RS), anxiety (ANX), and incentive salience (IS)—using validated and reliable self-
report, behavioral, and neurophysiological measures during each of three waves of data collection (15 months
apart). Alcohol involvement, AUD-related symptoms, and social-environment factors will be assessed at 5-month
intervals. Using this multi-wave, multimodal approach, we will address three specific aims: (1) characterize the
influence of the functional domains on the etiology of alcohol involvement; (2) accounting for the influence of
alcohol involvement, characterize the influence of the functional domains on the etiology of AUD-related
symptoms; and (3) characterize the influence of HD on functional domain neurobehavioral indicators. Analyses
will characterize how various combinations of domain indicators affect latent states of alcohol involvement
(volume of consumption; patterns of use) and AUD-related symptoms (numbers of symptoms; clusters of
symptoms) and transitions across latent states over time. This work will produce a unique and rich dataset, and
its findings will directly inform the development of personalized intervention and treatment strategies that can be
deployed to target the functioning of specific domains during periods when their influence is greatest.
项目摘要/摘要
酒精使用障碍(AUD)是高度不同的,因为它的症状非常多样化,而且通常是非
在各个个体之间重叠。从理论上讲,这种表型异质性反映了多重
潜在的原因,或致病机制。这种病因的复杂性使AUD的治疗非常具有挑战性;
研究人员已经确定,AUD的病因复杂性是发展更多疾病的最关键障碍
有效的个性化治疗。成瘾理论家已经确定了一套酒精成瘾研究领域
标准(AARDoC)功能域,被认为是AUD的重要病因机制。然而,现有的
旨在将这些机制与AUD相关行为和症状联系起来的模型没有考虑到病因。
因此,关于问题饮酒的病因和与AUD相关的症状的许多基本问题仍然存在
悬而未决。拟议的工作旨在确定功能域神经元的预期贡献。
青春期和青春期大量饮酒(HD)和AUD相关症状的病因学行为指标
进入成年期,这是HD和AUD相关症状最普遍的十年。我们
将招募480名青少年和初出茅庐的成年人(三个部分重叠的每个人各160人)作为目标样本
年龄队列[50%女性],预先筛查HD风险增加)参与一项前瞻性研究,使用
加速纵向设计,这将使我们能够表征酒精参与和AUD的轨迹-
在一项为期五年的研究中,在10年的发展期内出现相关症状。我们将使用一种神经临床
综合表征认知控制/去抑制四个功能域的评估方法
(DIS)、奖励敏感度(RS)、焦虑(ANX)和激励显著(IS)-使用有效且可靠的自我
在三波数据收集中的每一波(15个月)期间进行报告、行为和神经生理测量
分开)。5个月后将对酗酒、AUD相关症状和社会环境因素进行评估
间隔时间。使用这种多波、多模式的方法,我们将解决三个具体目标:(1)描述
功能域对酒精损害病因的影响;(2)解释了
酒精参与,表征功能域对AUD相关病因学的影响
(3)HD对功能领域神经行为指标的影响。分析
将表征区域指示剂的各种组合如何影响酒精参与的潜伏状态
(消耗量;使用模式)和与AUD相关的症状(症状数量;聚集
症状)以及潜伏状态随时间的转变。这项工作将产生一个独特而丰富的数据集,并且
它的发现将直接为个性化干预和治疗策略的发展提供信息,这些策略可以
部署的目的是在影响最大的时期针对特定领域的运作。
