背景：酒精购买任务（APT）提出了一个场景，询问参与者他们会以不同的价格购买和消费多少饮料，已经在学生和小型临床样本中使用，以获得酒精需求的测量，但没有在大型的一般人群样本中使用。方法：我们从普通人群（物质使用危险因素队列研究）中抽取大量年轻男性进行APT治疗。报告过去一年饮酒的参与者（n = 4790）、报告过去12个月饮酒情况、DSM-5酒精使用障碍（AUD）标准和酒精相关后果的参与者被纳入研究。结果：在APT的需求参数中，强度为8.7 (SD = 6.5)，表明当饮料是免费的时候，参与者报告的计划消费几乎是9杯。最大酒精消耗（O-max）超过35CHF (1CHF=1.1USD)，需求在8.4CHF （SD = 5.6）时变得有弹性（P-max）。抑制消费的平均价格为15.6瑞士法郎（SD =5.4）。指数方程对个体反应提供了满意的拟合（平均R-2: 0.8，中位数：0.8）。需求强度与酒精使用、AUD标准数量和后果数量相关（r均为>= 0.3,p < 0.0001）。(O-max);与饮酒相关（p < 0.0001）。弹性参数在预期方向上与酒精使用呈弱相关。结论：APT测量可用于描述普通人群中年轻男性对酒精的需求。需求可能为一般人群样本中酒精使用动机的强度提供临床有用的指标。2014爱思唯尔爱尔兰有限公司版权所有。
Background: The alcohol purchase task (APT), which presents a scenario and asks participants how many drinks they would purchase and consume at different prices, has been used among students and small clinical samples to obtain measures of alcohol demand but not in large, general population samples.Methods: We administered the APT to a large sample of young men from the general population (Cohort Study on Substance Use Risk Factors). Participants who reported drinking in the past year (n = 4790), reported on past 12 months alcohol use, on DSM-5 alcohol use disorder (AUD) criteria and on alcohol related consequences were included.Results: Among the APT's demand parameters, intensity was 8.7 (SD = 6.5) indicating that, when drinks are free, participants report a planned consumption of almost 9 drinks. The maximum alcohol expenditure (O-max) was over 35CHF (1CHF=1.1USD) and the demand became elastic (P-max) at 8.4CHF (SD = 5.6). The mean price at which the consumption was suppressed was 15.6CHF (SD =5.4). Exponential equation provided a satisfactory fit to individual responses (mean R-2: 0.8, median: 0.8). Demand intensity was correlated with alcohol use, number of AUD criteria and number of consequences (all r >= 0.3, p < 0.0001). (O-max); was correlated with alcohol use (p < 0.0001). The elasticity parameter was weakly correlated with alcohol use in the expected direction.Conclusion: The APT measures are useful in characterizing demand for alcohol in young men in the general population. Demand may provide a clinically useful index of strength of motivation for alcohol use in general population samples. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
