摘要
操作性需求香烟购买任务通常会提示参与者报告以单支香烟为单位的想象购买情况。虽然这种购买方式不同于实际购买场景中的单位(即20包),但没有研究调查了更生态有效的香烟包装单位的模拟购买如何映射到单个香烟购买指标。在这项研究中,212名参与者在三次香烟购买任务的迭代中报告了假设的香烟购买。其中两个以二进制格式收集的回答——会或不会购买——以联合单位价格,其中任务被区分为购买单支香烟或一包香烟。这种二元框架允许对保持一致时间框架的购买进行简化的概率描述。参与者还完成了标准的香烟购买任务,报告他们将以每单位价格购买和消费的单支香烟的数量。购买断点,或参与者报告购买香烟的最高价格,在这些任务中大致一致,在比较二元任务中的购买行为时则弱(r = .183)。等效性检验表明,单支香烟二元任务和每包二元任务报告的断点值之间存在有意义的差异,t(211) = -5.85, p < .001,标准购买任务和每包二元任务报告的断点值之间,t(211) = 11.49, p < .001。结果表明,需要更多的研究来确定哪些环境因素或强加的限制实际上影响了报告的卷烟价值。(PsycInfo Database Record (c) 2025 APA,版权所有)。
Operant demand for cigarettes varies by unit of purchase: Comparing purchasing of packs and individual cigarettes.
The operant demand cigarette purchase task conventionally prompts participants to report imagined purchases in units of single cigarettes. Although this purchasing modality diverges from the units deployed in real purchasing scenarios (i.e., packs of 20), no research has examined how simulated purchasing of the more ecologically valid unit of cigarette packs maps onto single cigarette purchasing metrics. A sample of 212 participants in this study reported hypothetical cigarette purchases across three iterations of the cigarette purchase task. Two of these collected responses in a binary format-would or would not purchase-at yoked unit prices, where tasks were distinguished as purchases of single cigarettes or packs of cigarettes. This binary framework permitted a simplified probabilistic description of purchasing that maintained a consistent timeframe. Participants also completed the standard cigarette purchase task, reporting the quantity of single cigarettes they would purchase and consume at each unit price. Purchasing breakpoint, or the highest price at which participants reported purchasing cigarettes, was broadly consistent across these tasks, weakly so when comparing purchases made on the binary tasks (r = .183). Tests of equivalence suggested that there were meaningful differences between breakpoint values reported on the single cigarette binary task and the per pack binary task, t(211) = -5.85, p < .001, and between breakpoint values reported on the standard purchase task and the per pack binary task, t(211) = 11.49, p < .001. Results suggest more research is needed to determine what environmental factors or imposed constraints are practically influencing reported cigarette valuation.
