本文描述了构成国际烟草控制政策评估项目（ITC项目）基础的概念模型，该项目的任务是衡量《烟草控制框架公约》（FCTC）关键政策对成年吸烟者、在一些国家对成年不吸烟者和青少年的心理社会和行为影响。评估框架利用多国控制、纵向设计和预先指定的、理论驱动的概念模型来检验关于具体政策预期效果的假设。ITC项目包括平行前瞻性队列调查，对目前在9个国家（占世界吸烟者的45%以上）的成年吸烟者的代表性样本进行调查，未来还会增加其他国家。总的来说，ITC调查构成了有史以来第一次烟草使用国际队列研究。国贸中心项目的概念模型借鉴了社会心理和健康传播文献，并假设烟草控制政策通过心理事件的因果链影响与烟草有关的行为，其中一些变量与政策本身关系更密切（具体政策变量），而其他变量则更接近于政策。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体（社会心理媒介）。我们讨论了ITC项目的目标及其为《烟草控制框架公约》建立证据基础的潜力。
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.
