Our Timeline: The figure above shows the evolution of Alberta’s Tomorrow Project (ATP);

ATP was launched in 2000 and recruitment continued until 2015. Questionnaires were administered throughout this period, so the type and number of surveys completed by a participant depend on when they joined.

For example, a participant recruited in 2001 was invited to fill out the Health and Lifestyle Questionnaire (HLQ), followed by the Canadian Diet History Questionnaire-I (CDHQ-I) and the Past-Year Total Physical Activity Questionnaire (PYTPAQ) as part of the baseline enrollment package. Such a participant would have been sent additional questionnaires in subsequent years, such as Survey 2004 and Survey 2008.

In 2008 ATP joined four other cohorts across Canada to form the Canadian Partnership for Tomorrow's Health (CanPath). Two versions of questionnaires were delivered during this time: the Updated Health and Lifestyle Questionnaire (UHLQ) along with the Physical Activity and Nutrition Survey (PANS) or the CORE questionnaire. Participants completed either UHLQ/PANS or CORE, as both contained very similar information.

Survey 2017 was a follow-up health and lifestyle questionnaire that was sent to ATP participants. In June to August 2020, the COVID-19 Questionnaire was administered to all participants to assess the impact of COVID-19 on Albertans. In September 2020, ATP implemented a COVID-19 Antibody Testing (CAT) study in a subset of ATP participants to measure infection- and vaccine-induced antibodies in the population and to understand lifestyle, behaviour, and socioeconomic changes experienced by Albertans during the pandemic.

Further information about the content of ATP questionnaires can be found on the Survey Information page.


Survey Completions


All ATP participants have completed one or more questionnaires, depending on when they joined ATP. The table below provides an estimate of the numbers of participants who have completed a single survey or combination of surveys, those who have provided a blood sample, and those diagnosed with cancer.

Further information and variable types available from each questionnaire can be found in Survey Information. ATP surveys can be found here.
