目的：行为经济购买任务是一种估计药品需求的任务，已经成功地开发出来并被广泛应用于卷烟。然而，电子烟还不存在有效的购买任务。本项目的目的是确定电子烟购买任务(E-CPT)的相关单位。方法：由当前电子烟使用者组成的焦点小组(N=7组28名参与者，每组2-7名参与者)。参与者讨论了他们的日常使用模式，完成了一份初步的电子烟测试，询问他们在价格上涨时每天会消费多少支电子烟，并讨论了这项任务在多大程度上准确地反映了他们的真实行为。小组被记录和转录；分析集中在与日常消费和E-CPT相关的陈述上。结果：参与者不太可能用泡芙来量化他们的日常使用，并且对E-CPT的适当单位的看法因设备类型而异。第一代设备(如雪茄)的用户报告说，相关单位是单个设备/盒；然而，为他们的设备购买尼古丁液体的参与者强调，以毫升为单位的电子液体体积更能反映他们的使用情况。结论：可能需要多个版本的电子烟来提供电子烟需求的有效衡量标准。
OBJECTIVES: Behavioral economic purchase tasks, which estimate demand for drugs, have been successfully developed for cigarettes and are widely used. However, a validated purchase task does not yet exist for e-cigarettes. The aim of this project was to identify the relevant units for an e-cigarette purchase task (E-CPT).METHODS: Focus groups (N=28 participants in 7 groups, 2-7 participants per group) consisting of current e-cigarette users were conducted. Participants discussed their daily use patterns, completed a preliminary E-CPT which asked how many puffs of their e-cigarette they would consume per day at escalating prices, and discussed the extent to which the task accurately reflected their real-world behavior. Groups were recorded and transcribed; analysis focused on statements related to daily consumption and the E-CPT.RESULTS: Participants were unlikely to quantify their daily use in terms of puffs, and perceptions about the appropriate unit for an E-CPT varied across device type. Users of first-generation devices (eg, cigalikes) reported that the relevant unit was the individual device/cartridge; however, participants who purchased nicotine liquid for their device emphasized that e-liquid volume in milliliters would better reflect their use.CONCLUSIONS: Multiple versions of the E-CPT may be necessary to provide valid measures of e-cigarette demand.
