The Community Health Activities Model Program (CHAMPS) physical activity questionnaire 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.
