The International Tobacco Control Policy Evaluation Project (the ITC Project) is an international research collaboration across more than 20 countries - Canada, United States, United Kingdom, Australia, Thailand, Malaysia, Republic of Korea, China, Mexico, Uruguay, New Zealand, France, Germany, the Netherlands, Bhutan, Ireland, Brazil, India, Bangladesh, Mauritius, Kenya, and Zambia. The primary objective of the ITC Project is to conduct rigorous evaluation of the psychosocial and behavioural effects of national-level tobacco control policies of the Framework Convention on Tobacco Control (FCTC). The ITC Project is conducting large-scale prospective cohort surveys of tobacco use to evaluate FCTC policies.
Each ITC Survey includes key measures for each FCTC policy domain that are identical or functionally similar across the 20+ countries to facilitate cross-country comparisons. The evaluation studies conducted from the ITC Surveys take advantage of natural experiments created when an ITC country implements a policy: changes in policy relevant variables in that country from pre- to post-policy survey waves are compared to other ITC countries where that policy has not changed. This research design provides high levels of internal validity, allowing more confident judgments regarding the possible causal impact of the policy.
A longitudinal cohort survey is simply a survey that measures the same variables across different populations, or countries in the case of ITC, and retains participants from year-to-year to monitor change in overall attitudes, knowledge, or behaviour within the population over time.

The original ITC Surveys were conducted using telephone interviewing, and this technique continues to be used in the new countries that have been added to the ITC Project.
With the introduction of ITC-Southeast Asia (Malaysia and Thailand), a new face-to-face interview was conducted with respondents. Telephone interviewing tends to be used in high-income ITC countries while face-to-face interviewing is typically used in low- and middle-income countries. Web interviewing is also used in some countries, either exclusively (e.g., the Netherlands) or in conjunction with telephone interviewing (e.g., Canada, the United State, the United Kingdom and Australia).
