Demographic characteristics including age, gender, race, education level, and socio-economic status will be recorded and used as covariates if necessary. Physical activity will be measured using the CHAMPS Physical Activity Questionnaire for Older Adults at baseline and follow-up.32 Activities of daily living will be assessed using the Pepper Assessment Tool for Disability (PAT-D) at baseline and follow-up. Additionally, activities of daily living will be assessed using the Mobility Assessment Tool - Short Form (MAT-sf) at baseline and follow-up. This is a novel, computerized tool for self-assessment of functional performance designed to reduce bias from factors such as age, gender and body image. The Short Form 12 (SF-12) will be used as a generic measure of health related quality of life. The questionnaire consists of two norm-based composite T-scales, assessing mental health and physical function. Lastly, mood will be assessed using the 10-item Center for Epidemiologic Studies Depression Scale (CES-D).
