酒精消费的行为经济需求曲线指数反映了以不同成本消费酒精的决策。尽管这些指数预测了与酒精有关的问题，超出了既定的预测指标，但人们对需求上升的决定因素知之甚少。两种可能构成酒精需求的认知结构是酒精接近倾向和饮酒认同。本研究的目的是评估这些构念的内隐和外显测量作为酒精需求曲线指数的预测因子。大学生饮酒者（N= 223，其中59%为女性）在间隔3个月的3个时间点完成了内隐和外显饮酒认同和酒精接近倾向的测量，并在时间3完成了酒精购买任务以评估需求。考虑到我们的酒精倾向和饮酒身份测量没有随时间变化，随机仅截距模型用于预测两个需求指数：振幅，代表最大的假设酒精消费和支出，以及持久性，代表对价格上涨的敏感性。当单独建模时，饮酒身份和酒精倾向的隐式和显式测量正预测需求指数。当内隐测量和外显测量同时包含在同一模型中时，饮酒认同的两个测量都预测了振幅，但只有外显饮酒认同预测了持久性。相比之下，酒精倾向的明确测量，而不是隐含测量，预测了两个需求指数。因此，有更多的支持明确的，而不是隐性的措施，作为酒精需求的独特预测因素。总体而言，饮酒身份和酒精倾向都与酒精需求呈正相关，并代表了潜在的可改变的认知结构，这可能是大学生饮酒者需求增加的基础。（PsycInfo数据库记录(c) 2023 APA，版权所有）
Behavioral economic demand curve indices of alcohol consumption reflect decisions to consume alcohol at varying costs. Although these indices predict alcohol-related problems beyond established predictors, little is known about the determinants of elevated demand. Two cognitive constructs that may underlie alcohol demand are alcohol-approach inclinations and drinking identity. The aim of this study was to evaluate implicit and explicit measures of these constructs as predictors of alcohol demand curve indices. College student drinkers (N= 223, 59% female) completed implicit and explicit measures of drinking identity and alcohol-approach inclinations at 3 time points separated by 3-month intervals, and completed the Alcohol Purchase Task to assess demand at Time 3. Given no change in our alcohol-approach inclinations and drinking identity measures over time, random intercept-only models were used to predict 2 demand indices: Amplitude, which represents maximum hypothetical alcohol consumption and expenditures, and Persistence, which represents sensitivity to increasing prices. When modeled separately, implicit and explicit measures of drinking identity and alcohol-approach inclinations positively predicted demand indices. When implicit and explicit measures were included in the same model, both measures of drinking identity predicted Amplitude, but only explicit drinking identity predicted Persistence. In contrast, explicit measures of alcohol-approach inclinations, but not implicit measures, predicted both demand indices. Therefore, there was more support for explicit, versus implicit, measures as unique predictors of alcohol demand. Overall, drinking identity and alcohol-approach inclinations both exhibit positive associations with alcohol demand and represent potentially modifiable cognitive constructs that may underlie elevated demand in college student drinkers.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
