Tobacco power walls display hundreds of tobacco products and are known to be a key part of the impact of point-of-sale tobacco advertising on risk for smoking in adolescents. The current study examined factors that are hypothesized to mediate the effect of tobacco power wall exposure on adolescents' susceptibility for smoking in the future.
Participants (N = 148) aged 11-17 years were invited to shop in the RAND StoreLab, a life-sized replica of a convenience store. They were randomized to 1 of 2 conditions: one in which the power wall was located in its typical position behind the cashier and the other in which it was hidden behind an opaque wall. Participants shopped in the RAND StoreLab and then completed measures of susceptibility for smoking in the future, perceived smoking norms, and perceived accessibility of cigarettes. Participants' movements in the store were electronically tracked.
Having the tobacco power wall behind the cashier increased adolescents' susceptibility for smoking in the future by 14.3% (total effect) compared with when the power wall was hidden (p = .01), and 14% of this effect was mediated by participants' perceived smoking norms. Time spent in front of the cashier and perceived accessibility of cigarettes did not play a role in the association between study condition and susceptibility for smoking in the future.
The tobacco power wall increases adolescents' smoking risk, and this effect is partly explained by the effect of the power wall on adolescents' perceptions of how normative smoking is. (PsycINFO Database Record
烟草陈列墙展示了数百种烟草产品，是销售点烟草广告对青少年吸烟风险影响的一个关键因素。本研究检验了假设的中介因素，这些因素可以调节暴露于烟草陈列墙对青少年未来吸烟易感性的影响。
邀请 11-17 岁的参与者进入 RAND 商店实验室，这是一个便利店的等比例复制品。他们被随机分配到以下两种条件之一：一种是烟草陈列墙位于收银员后面的典型位置，另一种是隐藏在不透明的墙后面。参与者在 RAND 商店实验室购物，然后完成未来吸烟易感性、感知吸烟规范和感知香烟可及性的测量。参与者在商店里的移动被电子跟踪。
与烟草陈列墙隐藏在不透明墙后面相比，将烟草陈列墙放在收银员后面会使青少年未来吸烟的易感性增加 14.3%（总效应）（p =.01），而这种效应的 14%是由参与者感知的吸烟规范所介导的。在收银员前停留的时间和感知香烟的可及性在研究条件与未来吸烟易感性之间的关联中没有起到作用。
烟草陈列墙增加了青少年的吸烟风险，这种效应部分是由烟草陈列墙对青少年对吸烟规范程度的感知的影响所解释的。（心理学信息数据库记录）
