GDS-15 = Geriatric Depression Scale; MHC = SF-36 MHC = Medical Outcomes Study Short Form 36-item mental health component subscale; NEADL = Nottingham Extended Activities of Daily Living Scale; SF-36 PHC = Medical Outcomes Study Short Form 36-item physical health component subscale; SPPB = Short physical performance battery;
aP values are for generalized linear mixed models using time as a repeated measure.
b Scores range from 0 to 22; higher score indicates greater function.
c Scores range from 0 to 12; higher score indicates better function.
d Scores range from 0 to 15; lower score indicates better mood.
e Scores range from 0 to 100; higher score indicates better physical health-related quality of life.
f Scores range from 0 to 100; higher score indicates better mental health-related quality of life.
