购买任务用于通过评估个人在一系列不断上涨的价格中购买的物质数量来衡量各种物质的价值或需求。大麻购买任务（MPT）以前已经开发过;然而，大麻可以以各种形式和测量方式消费，从而提出了关于MPT在大麻使用者中的适用性的问题。开发了一种自适应MPT，允许参与者选择他们喜欢的产品（例如，草药，dabs）和部门（例如，点击，克）。很少有研究来评估这些措施的时间稳定性。参与者（N= 50，M年龄= 35.3）报告至少每月使用大麻通过亚马逊的土耳其机械招募，并完成了基线和重复的原始和适应性MPT。72%（N= 36）的样本报告了相同的首选产品和部门。结果表明，基线和重复的原始MPT在所有指标中均显著相关（r范围= 0. 999，P <0. 05）。37-.而基线和重复适应MPT与P max显著相关（r=. 73）。31，p=. 029)和O max（r=. 57，p<. 001）。比较原始MPT和自适应MPT之间在所有指标上的差异的排列测试证明了断点的差异（r差异=. 52，p=. 004)和弹性（r差=. 94，p=. 005）。相关性较低的参与者谁切换他们的喜好对自适应MPT。只有弹性有显著差异（r差异=. 93，p=。012)没有改变偏好的参与者之间的任务。结果提供支持，原始和自适应MPT是可靠的，在重复测量，并证明评估大麻产品和部门的偏好的重要性。（PsycInfo数据库记录（c）2023阿帕，保留所有权利）
Purchase tasks are used to measure the value, or demand, for various substances by assessing the amount of a substance individuals would purchase across a series of escalating prices. Marijuana purchase task (MPT) has been previously developed; however, cannabis can be consumed in various forms and measurements, thus raising questions about the applicability of the MPT across cannabis users. An adaptive MPT was developed to allow participants to select their preferred product (eg, herbal, dabs) and division (eg, hits, grams). Little research has been done to assess the temporal stability of these measures. Participants (N= 50, M age= 35.3) who reported at least monthly cannabis use were recruited via Amazon’s Mechanical Turk and completed a baseline and repeated original and adaptive MPT. Seventy-two percent (N= 36) of the sample reported the same preferred product and division. Results indicated that the baseline and repeated original MPT were significantly correlated across all indices (r range=. 37–. 73), while the baseline and repeated adaptive MPT was significantly correlated with P max (r=. 31, p=. 029) and O max (r=. 57, p<. 001). Permutation testing comparing the difference between the original and adaptive MPT on all indices demonstrated a difference for break point (r difference=. 52, p=. 004) and elasticity (r difference=. 94, p=. 005). Correlations were lower between participants who switched their preferences on the adaptive MPT. Only elasticity was significantly different (r difference=. 93, p=. 012) between tasks among participants who did not switch their preferences. Results provide support that both the original and adaptive MPT are reliable across repeated measurement and demonstrate the importance of assessing cannabis product and division preferences.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
