large US cohort of community-dwelling older adults.

Independent and Vital Elderly (ACTIVE) randomized,
controlled trial, baseline depressive symptoms had
no direct effect on functional change in three
years. However, baseline depressive symptoms
inversely influenced baseline functional performance

The effect of baseline processing speed ability on
baseline functional performance was mediated by
memory and reasoning abilities. At the same time,
reasoning ability change in three years was
significant mediators between depressive symptoms
and functional performance change. The results of

of the elderly over time. They can serve as the
basis of intervention or prevention of functional
impairment due to depressive symptoms among the
