We assessed the reliability of a measure of the latent construct "smoking sensory experience." We further measured the relationship between "smoking sensory experience" and smokers' rating of the importance of the appearance of cigarettes/cigarette packs in brand choice and smoking dependence.
Analyses involved a national sample of smokers (n = 633) who participated in the 2010 South African Social Attitudes Survey (N = 3,112). Smokers ranked on a scale of 1-5, the importance of the following attributes in choosing their cigarette brand: health concerns, cost, packaging, taste, satisfaction, and flavor/strength. Using structural equation modeling, an a priori model was specified based on the hypothesis that taste, satisfaction, and flavor/strength are measures of a construct of "smoking sensory experience" and that cigarette packaging would be positively related to "smoking sensory experience." Furthermore, "smoking sensory experience" would be positively related to cigarettes smoked per day.
The latent construct--"smoking sensory experience" was considered reliable (Cronbach's α = 0.75). The structural equation model confirmed that the specified model fitted the data well (goodness of fit index = 0.993; normed fit index = 0.978; root mean square error of approximation = 0.031). Higher "smoking sensory experience" was positively associated with increasing cigarettes smoked per day (β = 0.12). Higher rating of the cigarette package in brand choice positively covaried with both "smoking sensory experience" (β = 0.29), and higher rating of health considerations (β = 0.42).
These findings support the regulation of the appearance of cigarettes/cigarette packs to reduce cigarettes' appeal and abuse liability in line with Article 11 of WHO's Framework Convention on Tobacco Control.
我们评估了潜在结构“吸烟感官体验”测量方法的可靠性。我们还进一步测量了“吸烟感官体验”与吸烟者对香烟/烟包外观在品牌选择中的重要性评级以及吸烟依赖性之间的关系。
分析涉及参与2010年南非社会态度调查(样本量N = 3112)的全国吸烟者样本(n = 633)。吸烟者按照1 - 5的量表对选择香烟品牌时以下属性的重要性进行排序:对健康的担忧、成本、包装、口味、满意度以及风味/强度。使用结构方程模型,基于以下假设指定了一个先验模型:口味、满意度和风味/强度是“吸烟感官体验”结构的测量指标,并且香烟包装与“吸烟感官体验”呈正相关。此外,“吸烟感官体验”与每日吸烟量呈正相关。
潜在结构——“吸烟感官体验”被认为是可靠的(克朗巴哈α系数 = 0.75)。结构方程模型证实指定模型与数据拟合良好(拟合优度指数 = 0.993;规范拟合指数 = 0.978;近似均方根误差 = 0.031)。较高的“吸烟感官体验”与每日吸烟量增加呈正相关(β = 0.12)。在品牌选择中对香烟包装的较高评级与“吸烟感官体验”(β = 0.29)以及对健康因素的较高评级(β = 0.42)均呈正协变关系。
这些发现支持根据世界卫生组织《烟草控制框架公约》第11条对香烟/烟包外观进行监管,以降低香烟的吸引力和滥用可能性。
