The ITC Policy Evaluation Project started its first project, the ITC Four-Country Project in 2002, to measure the psychosocial and behavioural factors of smoking in Australia, Canada, the United Kingdom, and the United States. The ITC team is currently undergoing a seventh wave of data collection. The other ITC countries joined the project at different times after the Four-Country project began, and therefore are in different waves of data collection.
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. To date, over 7,500 smokers, non-smokers, and youth have participated in the ITC-SEA project.
Now, most of the ITC countries, use telephone interviewing, although some countries such as Malaysia and China use a mixture of telephone and face-to-face interviewing.

The ITC Project mission is to evaluate the psychosocial and behavioural effects of national-level tobacco control policies throughout the world.The project follows thousands of adult smokers over five or more years from the survey start date in their respective countries. The start dates are strategically chosen to follow changes in national-level tobacco policies according to the recommendations of the first and currently only international treaty on health, the Framework Convention on Tobacco Control (FCTC).
The study focuses not only on whether a given policy has its desired effect, but also on how and why those policy effects are achieved. The first wave of surveys in each country is administered just before a large policy change takes place. The surveys continue over a five year period to monitor the impact of likely FCTC-based policy changes as they are implemented, allowing researchers to perform a series of multiple natural experiments.
