Developing briefer behavioral economic measures is an important priority to ensure that these measures can be used in a variety of different contexts and to reduce participant burden. We developed and sought to validate a Brief Assessment of Cigarette Demand (BACD). A 17-item Cigarette Purchase Task (CPT) and a 3-item BACD were completed concurrently in 2 community samples of smokers (Study 1, adult smokers [n = 80] with substance use disorders; Study 2, adolescent smokers [n = 81]). Responses on the CPT and BACD were compared on the following demand indices: (a) intensity (the number of cigarettes requested at no cost), (b) Omax (the maximum expenditure on cigarettes in a 24-hr period), and (c) breakpoint (the point at which consumption is totally suppressed/no cigarettes are purchased). Correlations of demand indices with cigarettes per day and nicotine dependence were calculated. Measures of cigarette demand on the CPT and BACD were significantly correlated, albeit at very different magnitudes, for all 3 indices in the adult sample (intensity, r = .86; breakpoint, r = .23; and Omax, r = .43) and for 2 of the indices in the adolescent sample (intensity, r = .97; breakpoint, r = .33). The CPT and BACD relationships with smoking and nicotine dependence were similar for breakpoint and intensity but not for Omax. As initial findings were mixed, additional validation work is recommended to improve psychometric properties before adoption. Valid brief measures of demand could have utility for research and treatment of addictive disorders. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
开发更简洁的行为经济学测量方法是一个重要的优先事项，以确保这些方法可以在各种不同的情况下使用，并减轻参与者的负担。我们开发并试图验证了一个简短的香烟需求评估（BACD）。在两个社区吸烟人群样本中（研究 1，成年吸烟者[有物质使用障碍的人群，n = 80]；研究 2，青少年吸烟者，n = 81），同时完成了 17 项香烟购买任务（CPT）和 3 项 BACD。在以下需求指标上比较了 CPT 和 BACD 的响应：（a）强度（免费要求的香烟数量），（b）Omax（24 小时内购买香烟的最大支出），和（c）断点（消费完全抑制/不购买香烟的点）。计算了需求指标与每天吸烟量和尼古丁依赖之间的相关性。CPT 和 BACD 上的香烟需求测量在成年样本中的所有 3 个指标（强度，r =.86；断点，r =.23；和 Omax，r =.43）以及青少年样本中的 2 个指标（强度，r =.97；断点，r =.33）上显著相关，尽管相关程度非常不同。CPT 和 BACD 与吸烟和尼古丁依赖的关系在断点和强度上相似，但在 Omax 上则不然。由于最初的发现喜忧参半，因此建议进行额外的验证工作，以提高采用前的心理测量特性。需求的有效简短测量方法可能对成瘾障碍的研究和治疗有用。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
