Alcohol use disorder (AUD) is an etiologically heterogeneous psychiatric disorder defined by a collection of commonly observed co-occurring symptoms. It is useful to contextualize AUD within theoretical frameworks to identify potential prevention, intervention, and treatment approaches that target personalized mechanisms of behavior change. One theoretical framework, behavioral economics, suggests that AUD is a temporally extended pattern of cost/benefit analyses favoring drinking decisions. The distribution of costs and benefits across choice outcomes is often unequally distributed over time and has different probabilities of receipt, such that delay and probability become critical variables. The present study examines the relations between different forms of economic discounting (delayed reward, delayed cost, and probabilistic reward) and individual symptoms of AUD to inform etiological models.
Participants ( = 732; 41% female, 4.2% Black, 88.1% White, 8% Hispanic) completed an online survey with measures of AUD symptoms and economic discounting. We examined relations between economic discounting and AUD symptoms with zero-order correlations, in separate models (factor models), and in models controlling for an AUD factor (factor-controlled models).
Delayed reward discounting was positively associated with the give up AUD criteria across all three levels of analysis. Probability discounting was associated with social/interpersonal problems across two out of three sets of analyses. Consistent with the broad discounting literature, effect sizes were small (range = -.15 to .13).
These results support the idea that AUD criteria are etiologically distinct, resulting in varying AUD profiles between persons that are differentially associated with behavioral economic discounting. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
酒精使用障碍(AUD)是一种病因异质性的精神障碍,其特征是一系列常见的共病症状。在理论框架内将 AUD 置于背景下有助于确定潜在的预防、干预和治疗方法,这些方法针对的是个性化的行为改变机制。理论框架之一——行为经济学表明,AUD 是一种倾向于饮酒决策的时间延长的成本/收益分析模式。成本和收益在选择结果中的分布在时间上往往是不平等的,并且具有不同的获得概率,因此延迟和概率成为关键变量。本研究通过检验不同形式的经济折扣(延迟奖励、延迟成本和概率奖励)与 AUD 个体症状之间的关系,为病因模型提供信息。
参与者(n=732;41%为女性,4.2%为黑人,88.1%为白人,8%为西班牙裔)完成了一项在线调查,调查内容包括 AUD 症状和经济折扣。我们使用零阶相关、单独模型(因素模型)和控制 AUD 因素的模型(因素控制模型)检验了经济折扣与 AUD 症状之间的关系。
延迟奖励折扣与所有三种分析水平的放弃 AUD 标准呈正相关。概率折扣与社交/人际问题在两种分析中有两种情况相关。与广泛的折扣文献一致,效应大小较小(范围为-.15 到.13)。
这些结果支持这样一种观点,即 AUD 标准在病因上是不同的,导致个体之间存在不同的 AUD 特征,这些特征与行为经济学折扣存在差异。(美国心理协会,2023)。
