烟盒上的图片警告增加了戒烟的动力。我们试图检验负面情绪、信息抗拒（即对信息的反对反应）和感知风险在形成戒烟意图中的潜在中介作用。在2014年和2015年，我们随机分配了2149名成年美国吸烟者，让他们在四周内接受烟盒上的图片警告或纯文字警告。分析使用带有自举标准误差的结构方程模型来检验我们理论化的中介模型。图片警告增加了负面影响、信息抗拒和戒烟意图（均p< 0.001），但没有增加感知风险（即吸烟危害的感知可能性和严重程度）。负性情绪介导图片警告对戒烟意向的影响（中介效应= 0.16,p< 0.001）。信息阻抗削弱了图片警告对戒烟意图的影响，尽管影响很小（中介效应=−）。04, p <措施)。虽然图片警告不直接影响感知风险，但该模型显示，通过负面影响及其与感知风险的正相关（中介效应= 0.02,p< 0.001），以及抗拒及其与感知风险的负相关（中介效应= -），对戒烟意图有额外的小中介效应。01, p <措施)。烟盒上的图片警告通过增加负面影响而增加了戒烟的意图。信息电抗部分减弱了这种意图的增加。消极情绪和抗拒对感知风险的相反关联可以解释为什么图片警告没有导致感知风险的可观察变化。
Pictorial warnings on cigarette packs increase motivation to quit smoking. We sought to examine the potential mediating role of negative affect, message reactance (i.e., an oppositional reaction to a message), and perceived risk in shaping quit intentions. In 2014 and 2015, we randomly assigned 2,149 adult US smokers to receive either pictorial warnings or text-only warnings applied to their cigarette packs for four weeks. Analyses used structural equation modeling with bootstrapped standard errors to test our theorized mediational model. Pictorial warnings increased negative affect, message reactance, and quit intentions (all p<.001), but not perceived risk (i.e., perceived likelihood and severity of harms of smoking). Negative affect mediated the impact of pictorial warnings on quit intentions (mediated effect=.16, p<.001). Message reactance weakened the impact of pictorial warnings on quit intentions, although the effect was small (mediated effect=−.04, p<.001). Although pictorial warnings did not directly influence perceived risk, the model showed additional small mediation effects on quit intentions through negative affect and its positive association with perceived risk (mediated effect=.02, p<.001), as well as reactance and its negative association with perceived risk (mediated effect=−.01, p<.001). Pictorial cigarette pack warnings increased quit intentions by increasing negative affect. Message reactance partially attenuated this increase in intentions. The opposing associations of negative affect and reactance on perceived risk may explain why pictorial warnings did not lead to observable changes in perceived risk.
