The Clinical visit version of PROactive Physical Activity in COPD (C-PPAC) is a hybrid instrument that aims at measuring physical activity experience. It covers two domains: the amount of physical activity and the difficulty during physical activity. Additionally, it reports a total score combining both domains.
The C-PPAC consists of 14 items (12 questions from a patient reported questionnaire, and two outputs from an activity monitor). The C-PPAC questionnaire is intended to be completed by people with COPD after an objective seven-day assessment of their physical activity. The domains are distributed as follow:
- The amount of physical activity domain is covered by the first two items of the questionnaire (regarding the amount of walking and the amount of chores performed outside), and by two outputs from an activity monitor (Vector Magnitude Units per minute (VMU/min) and steps/day).
- The difficulty during physical activity domain is covered by the remaining ten items of the questionnaire.
- The total score is calculated as the average of both the amount and difficulty domains.
