There are four instruments that collect physical activity data by self reports.


The Community Health Activities Model Program (CHAMPS) Physical Activity Questionnaire (PAQ) is a self-administered computer questionnaire designed for older adults. Participants were asked to recall if they engaged in 40 specific activities in the last 4 weeks. The weekly frequency and duration were asked for each activity completed.
