To examine the extent to which increasingly plainer packaging might increase recall of health warnings.
A 4 (pack ID levels) x 2 (smoking status: smokers and non-smokers) between-subjects design in which participants were randomly assigned to view one package.
Two hundred and twenty students from three universities in Nova Scotia, Canada, participated in the survey.
Participants were asked to recall the health warning on their package.
A sequential binary logistic regression test to examine whether plain packaging and/or smoking status affects health warning recall.
The odds of recalling the correct health warnings were significantly higher for the two plainest packages relative to the original package. The odds of recalling the correct health warning were also higher for non-smokers relative to smokers.
The results provide compelling evidence that health warnings on plain packages can be more easily recalled.
研究包装日益简化在多大程度上可能提高对健康警示的回忆率。
采用4(包装标识水平)×2(吸烟状况:吸烟者和非吸烟者)组间设计,参与者被随机分配观看一种包装。
来自加拿大新斯科舍省三所大学的220名学生参与了该调查。
要求参与者回忆他们所看包装上的健康警示。
采用序贯二元逻辑回归检验,以考察包装简化和/或吸烟状况是否会影响对健康警示的回忆。
相对于原始包装,两种最简化包装的参与者回忆起正确健康警示的几率显著更高。相对于吸烟者,非吸烟者回忆起正确健康警示的几率也更高。
研究结果提供了有力证据,表明简化包装上的健康警示更容易被回忆起来。
