MOBILIZE = Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly
SOF = Study of Osteoporotic Fractures (Ensrud et al., 2008)
CHS = Cardiovascular Health Study (Fried et al., 2001)
SPPB = short physical performance battery (lower scores indicate more impairment)
ADL = activities of daily living (higher scores indicate more impairment)
IADL = instrumental activities of daily living (higher scores indicate more impairment)
Hopkins Verbal Learning Test (lower scores indicate more impairment)
MMSE = mini-mental state examination. (lower scores indicate more impairment)
Trails A = part A of the Trail Making Test (higher scores indicate more impairment)
Trails B = part B of the Trail Making Test (higher scores indicate more impairment)
Clock-in-a-Box = a modification of the Clock Drawing test (lower scores indicate more impairment)
Word Generation (words starting with the letters F, A & S) (lower scores indicate more impairment)
Word Generation (animals – independent of letter starting the name) (lower scores indicate more impairment)
CESD = centers for epidemiologic studies depression scale (revised) (higher scores indicate more depression)
PASE = Physical Activity Scale for the Elderly (higher score indicates more activity)
Note: Reduced energy level was assessed using the CESD (Center for Epidemiologic Studies Depression Scale) question, “Over the past week or so, did you feel like you could not get going”
