(SuPA Mobility Trial) This research is investigating the effects of health coaching on physical activity, mobility, and other health domains like cognitive function. The purpose of this research is to determine whether 6 months of one-on-one health coaching or group-based health education sessions will increase physical activity and improve mobility in individuals who are experiencing difficulties with their mobility (e.g., slower walking). There will be one 60-minute and eight 20-minute coaching or group sessions over 6 months. As part of the study, you will also complete assessment sessions at the beginning, middle, and end of the study. Contact: 604-875-4111 ext.69223
