The social and health care costs of smoking are immense. To reduce these costs, several tobacco control policies have been introduced (eg, graphic health warnings [GHWs] on cigarette packs). Previous research has found plain packaging (a homogenized form of packaging), in comparison to branded packaging, effectively increases attention to GHWs using UK packaging prototypes. Past studies have also found that illness sensitivity (IS) protects against health-impairing behaviors. Building on this evidence, the goal of the current study was to assess the effect of packaging type (plain vs. branded), IS level, and their interaction on attention to GHWs on cigarette packages using proposed Canadian prototypes.
We assessed the dwell time and fixations on the GHW component of 40 cigarette pack stimuli (20 branded; 20 plain). Stimuli were presented in random order to 50 smokers (60.8% male; mean age = 33.1; 92.2% daily smokers) using the EyeLink 1000 system. Participants were divided into low IS (n = 25) and high IS (n = 25) groups based on scores on the Illness Sensitivity Index.
Overall, plain packaging relative to branded packaging increased fixations (but not dwell time) on GHWs. Moreover, low IS (but not high IS) smokers showed more fixations to GHWs on plain versus branded packages.
These findings demonstrate that plain packaging is a promising intervention for daily smokers, particularly those low in IS, and contribute evidence in support of impending implementation of plain packaging in Canada.
Our findings have three important implications. First, our study provides controlled experimental evidence that plain packaging is a promising intervention for daily smokers. Second, the findings of this study contribute supportive evidence for the impending plain packaging policy in Canada, and can therefore aid in defense against anticipated challenges from the tobacco industry upon its implementation. Third, given its effects in increasing attention to GHWs, plain packaging is an intervention likely to provide smokers enhanced incentive for smoking cessation, particularly among those low in IS who may otherwise be less interested in seeking treatment for tobacco dependence.
吸烟的社会和医疗保健成本巨大。为了降低这些成本,已经出台了几项烟草控制政策(例如,香烟包装上的图形健康警示[GHW])。先前的研究发现,与品牌包装相比,普通包装(一种包装的同质化形式)有效地提高了对使用英国包装原型的 GHW 的关注度。过去的研究还发现,疾病敏感性(IS)可以预防对健康有害的行为。基于这一证据,本研究的目的是评估包装类型(普通与品牌)、IS 水平及其相互作用对使用拟议的加拿大原型对香烟包装上 GHW 的关注度的影响。
我们评估了 40 个香烟包装刺激物(20 个品牌;20 个普通)中 GHW 组件的停留时间和注视次数。使用 EyeLink 1000 系统以随机顺序向 50 名吸烟者(60.8%为男性;平均年龄 33.1 岁;92.2%为每日吸烟者)呈现刺激物。参与者根据疾病敏感性指数的得分分为低 IS 组(n=25)和高 IS 组(n=25)。
总体而言,与品牌包装相比,普通包装增加了对 GHW 的注视次数(但不是停留时间)。此外,低 IS(而不是高 IS)吸烟者在普通包装与品牌包装上对 GHW 的注视次数更多。
这些发现表明,普通包装是日常吸烟者的一种很有前途的干预措施,特别是对于 IS 较低的吸烟者,为即将在加拿大实施普通包装提供了证据支持。
我们的发现有三个重要意义。首先,我们的研究提供了控制实验证据,表明普通包装是日常吸烟者的一种很有前途的干预措施。其次,本研究的结果为加拿大即将实施的普通包装政策提供了支持性证据,因此可以帮助抵御该政策实施后烟草业可能带来的预期挑战。第三,鉴于其增加对 GHW 关注度的效果,普通包装是一种干预措施,可能会为吸烟者提供更强的戒烟动力,特别是对于那些 IS 较低的吸烟者,他们可能对寻求烟草依赖治疗的兴趣不大。
