酒精购买任务（APT）越来越多地用于评估酒精的行为经济需求。以前的研究利用APT通常评估的需求假设的结果，使这些假设的措施在多大程度上反映偏好时，实际的回报是一个重要的实证问题。这项研究检查了假设和激励APT的酒精需求。19名男性重度饮酒者完成了两项APT-一项是假设酒精，另一项是随机选择的结果。参与者有机会在模拟酒吧环境中的自我管理期间消耗与他们对激励APT的选择相关的酒精。结果表明，APT版本之间的对应关系一般密切，虽然参与者更敏感的价格上涨，并倾向于在激励版本的低价格消费更多。对激励APT的估计消耗量与实验室中消耗的酒精量高度相关（r = 0.87，p <0.001），表明APT响应是实际饮酒行为的有效指标。这些结果提供了进一步的证据一致性的需求为基础的决策时，奖励是假设与实际可用。行为经济学方法成瘾行为的影响和未来的研究方向进行了讨论。
Alcohol purchase tasks (APTs) are increasingly being used to assess behavioral economic demand for alcohol. Prior studies utilizing APTs have typically assessed demand for hypothetical outcomes, making the extent to which these hypothetical measures reflect preferences when actual rewards are at stake an important empirical question. This study examined alcohol demand across hypothetical and incentivized APTs. Nineteen male heavy drinkers completed two APTs—one for hypothetical alcohol and another in which one randomly-selected outcome was provided. Participants were given an opportunity to consume the alcohol associated with their choice on the incentivized APT during a self-administration period in a simulated bar environment. Results indicated generally close correspondence between APT versions, though participants were more sensitive to increases in price and tended to consume more at low prices on the incentivized version. Estimated consumption on the incentivized APT was highly correlated with the amount of alcohol consumed in the laboratory (r = .87, p < .001), suggesting that APT responses are valid indicators of actual drinking behavior. These results provide further evidence of congruence of demand-based decision-making when rewards are hypothetical vs. actually available. Implications for behavioral economic approaches to addictive behavior and directions for future research are discussed.
