Some researchers have raised concerns that pictorial health warning labels (HWLs) on cigarette packages may lead to message rejection and reduced effectiveness of HWL messages. This study aimed to determine how state reactance (i.e., negative affect due to perceived manipulation) in response to both pictorial and text-only HWLs is associated with other types of HWL responses and with subsequent cessation attempts.
Survey data were collected every 4 months between September 2013 and 2014 from online panels of adult smokers in Australia, Canada, Mexico, and the US were analyzed. Participants with at least one wave of follow-up were included in the analysis (n = 4,072 smokers; 7,459 observations). Surveys assessed psychological and behavioral responses to HWLs (i.e., attention to HWLs, cognitive elaboration of risks due to HWLs, avoiding HWLs, and forgoing cigarettes because of HWLs) and cessation attempts. Participants then viewed specific HWLs from their countries and were queried about affective state reactance. Logistic and linear Generalized Estimating Equation (GEE) models regressed each of the psychological and behavioral HWL responses on reactance, while controlling for socio-demographic and smoking-related variables. Logistic GEE models also regressed having attempted to quit by the subsequent survey on reactance, each of the psychological and behavioral HWL responses (analyzed separately), adjustment variables. Data from all countries were initially pooled, with interactions between country and reactance assessed; when interactions were statistically significant, country-stratified models were estimated.
Interactions between country and reactance were found in all models that regressed psychological and behavioral HWL responses on study variables. In the US, stronger reactance was associated with more frequent reading of HWLs and thinking about health risks. Smokers from all four countries with stronger reactance reported greater likelihood of avoiding warnings and forgoing cigarettes due to warnings, although the association appeared stronger in the US. Both stronger HWLs responses and reactance were positively associated with subsequent cessation attempts, with no significant interaction between country and reactance.
Reactance towards HWLs does not appear to interfere with quitting, which is consistent with its being an indicator of concern, not a systematic effort to avoid HWL message engagement.
一些研究人员担心香烟包装上的图片健康警示标签(HWLs)可能会导致信息被拒以及HWL信息的有效性降低。本研究旨在确定对图片和纯文本HWLs的状态反抗(即由于感知到的操纵而产生的负面影响)如何与其他类型的HWL反应以及随后的戒烟尝试相关联。
收集了2013年9月至2014年期间每4个月从澳大利亚、加拿大、墨西哥和美国的成年吸烟者在线小组获得的调查数据并进行分析。分析纳入了至少有一波随访的参与者(n = 4072名吸烟者;7459次观察)。调查评估了对HWLs的心理和行为反应(即对HWLs的关注、因HWLs对风险的认知阐述、避开HWLs以及因HWLs而放弃吸烟)以及戒烟尝试。参与者随后查看了来自其国家的特定HWLs,并被询问情感状态反抗情况。逻辑和线性广义估计方程(GEE)模型在控制社会人口统计学和吸烟相关变量的同时,将每种心理和行为HWL反应对反抗进行回归分析。逻辑GEE模型还将在后续调查中尝试戒烟对反抗、每种心理和行为HWL反应(分别分析)、调整变量进行回归分析。所有国家的数据最初进行合并,并评估国家与反抗之间的相互作用;当相互作用具有统计学意义时,估计国家分层模型。
在所有将心理和行为HWL反应对研究变量进行回归分析的模型中,均发现了国家与反抗之间的相互作用。在美国,更强的反抗与更频繁地阅读HWLs以及思考健康风险相关。来自所有四个国家的反抗较强的吸烟者报告称,因警示而避开警示和放弃吸烟的可能性更大,尽管这种关联在美国似乎更强。更强的HWL反应和反抗均与随后的戒烟尝试呈正相关,国家与反抗之间无显著相互作用。
对HWLs的反抗似乎不会干扰戒烟,这与其作为一种关注指标而非避免参与HWL信息的系统性努力是一致的。
