The Past Year Total Physical Activity Questionnaire was designed as a self-administered questionnaire that would capture physical activities done in the previous 12 months from time of questionnaire completion. It is based on the LTPAQ and also assesses all domains and parameters of physical activity. This questionnaire was tested for validity and reliability  and has been adapted for use in Phase 1 of the Alberta Tomorrow Project and in other cohort studies and randomized controlled trials.
