This paper describes the conceptual model that underlies the International Tobacco Control Policy Evaluation Project (ITC Project), whose mission is to measure the psychosocial and behavioural impact of key policies of the Framework Convention on Tobacco Control (FCTC) among adult smokers, and in some countries, among adult non-smokers and among youth. The evaluation framework utilises multiple country controls, a longitudinal design, and a pre-specified, theory-driven conceptual model to test hypotheses about the anticipated effects of specific policies. The ITC Project consists of parallel prospective cohort surveys of representative samples of adult smokers currently in nine countries (inhabited by over 45% of the world's smokers), with other countries being added in the future. Collectively, the ITC Surveys constitute the first-ever international cohort study of tobacco use. The conceptual model of the ITC Project draws on the psychosocial and health communication literature and assumes that tobacco control policies influence tobacco related behaviours through a causal chain of psychological events, with some variables more closely related to the policy itself (policy-specific variables) and other variables that are more downstream from the policy, which have been identified by health behaviour and social psychological theories as being important causal precursors of behaviour (psychosocial mediators). We discuss the objectives of the ITC Project and its potential for building the evidence base for the FCTC.
本文介绍了国际烟草控制政策评估项目（ITC项目）的概念模型，该项目的任务是衡量《烟草控制框架公约》（FCTC）主要政策对成年吸烟者、在一些国家还包括成年非吸烟者和青少年的心理社会及行为影响。评估框架采用多国家对照、纵向设计以及预先设定的、理论驱动的概念模型，以检验关于特定政策预期效果的假设。ITC项目由对九个国家（居住着全球超过45%的吸烟者）成年吸烟者代表性样本的平行前瞻性队列调查组成，未来还会增加其他国家。ITC调查共同构成了有史以来第一项关于烟草使用的国际队列研究。ITC项目的概念模型借鉴了心理社会和健康传播文献，并假设烟草控制政策通过一系列心理事件的因果链影响与烟草相关的行为，其中一些变量与政策本身联系更紧密（特定政策变量），而其他变量则处于政策的下游，健康行为和社会心理学理论已将其确定为行为的重要因果前因（心理社会中介变量）。我们讨论了ITC项目的目标及其为FCTC建立证据基础的潜力。
