酒精使用障碍(AUDS)的行为经济学方法强调酒精使用的个人和环境决定因素。目前的研究考察了61名酗酒者(62%患有澳元)的酒精需求(即，在价格不断上涨的情况下饮酒动机)和延迟奖励折扣(即，倾向于立即获得少量奖励，而不是延迟获得更大奖励)的个体差异。此外，基于强调渴望在回报评估中的作用和对直接回报的偏好的理论描述，对酒精的渴望也与这些行为经济变量和与酒精相关的变量进行了研究。酒精需求强度和延迟奖励折扣与AUD症状显著相关，但与酒精使用的量化指标无关，而且彼此之间也存在中等程度的相关性。同样，渴望与AUD症状显著相关，但与饮酒无关，也与需求强度和延迟奖励折扣显著相关。这些发现进一步强调了动机的行为经济学指标与酒精使用障碍的相关性，以及渴望酒精在这种关系中的潜在重要性。
A behavioral economic approach to alcohol use disorders (AUDs) emphasizes both individual and environmental determinants of alcohol use. The current study examined individual differences in alcohol demand (i.e., motivation for alcohol under escalating conditions of price) and delayed reward discounting (i.e., preference for immediate small rewards compared to delayed larger rewards) in 61 heavy drinkers (62% with an AUD). In addition, based on theoretical accounts that emphasize the role of craving in reward valuation and preferences for immediate rewards, craving for alcohol was also examined in relation to these behavioral economic variables and the alcohol-related variables. Intensity of alcohol demand and delayed reward discounting were significantly associated with AUD symptoms, but not with quantitative measures of alcohol use, and were also moderately correlated with each other. Likewise, craving was significantly associated with AUD symptoms, but not with alcohol use, and was also significantly correlated with both intensity of demand and delayed reward discounting. These findings further emphasize the relevance of behavioral economic indices of motivation to alcohol use disorders and the potential importance of craving for alcohol in this relationship.
