引言：需要经验证的方法来评估消费者对改良风险烟草产品（MRTPs）的反应。在现有文献的指导下，证明了规范信念和未来使用烟草的意图之间的关系，目前的研究试图（1）开发一种关于无烟烟草（ST）的规范信念的测量方法，并建立潜在的因素结构，（2）利用独立的青年样本进行验证性因素分析来评估该结构，（3）建立该测量方法的同时效度。受访者（吸烟者和非吸烟者，年龄在15-65岁; N = 2991）完成了一项基于网络的调查，其中包括人口统计学特征，烟草使用史和依赖，以及对ST的态度的措施改编自规范的吸烟信念规模。第二个样本的青年（14-17岁; N = 305）完成了类似的questionnaire.Results：探索性因素分析产生了预期的三因素解决方案，并占近四分之三的方差的数据反映（1）感知的流行率ST使用，（2）流行的ST之间成功/精英，和（3）批准ST使用的父母/同龄人。从青年样本的数据验证性因素分析表明，良好的模型拟合。Logistic回归分析表明，规模有效区分ST用户和nonusers和相关的利益，在尝试snus.Conclusions：评估的MRTPs监管的目的，它允许降低风险的消息，应包括社会规范的测量。此外，跟踪新MRTPs使用情况的监测工作应包括社会规范措施，以确定规范如何随着使用的普遍性而变化。
Introduction: Validated methods to evaluate consumer responses to modified risk tobacco products (MRTPs) are needed. Guided by existing literature that demonstrates a relationship between normative beliefs and future intentions to use tobacco the current research sought to (1) develop a measure of normative beliefs about smokeless tobacco (ST) and establish the underlying factor structure, (2) evaluate the structure with confirmatory factor analysis utilizing an independent sample of youth, and (3) establish the measure's concurrent validity.Methods: Respondents (smokers and nonsmokers aged 15-65; N = 2991) completed a web-based survey that included demographic characteristics, tobacco use history and dependence, and a measure of attitudes about ST adapted from the Normative Beliefs about Smoking scale. A second sample of youth (aged 14-17; N = 305) completed a similar questionnaire.Results: Exploratory factor analysis produced the anticipated three-factor solution and accounted for nearly three-quarters of the variance in the data reflecting (1) perceived prevalence of ST use, (2) popularity of ST among successful/elite, and (3) approval of ST use by parents/peers. Confirmatory factor analysis with data from the youth sample demonstrated good model fit. Logistic regression demonstrated that the scales effectively discriminate between ST users and nonusers and are associated with interest in trying snus.Conclusions: Assessment of MRTPs for regulatory purposes, which allows messages of reduced risk, should include measurement of social norms. Furthermore, surveillance efforts that track use of new MRTPs should include measures of social norms to determine how norms change with prevalence of use.y
