Depression
This study evaluated depression using a Korean form of the
Geriatric Depression Scale (KGDS). The KGDS is a tool
that was developed by translating the Geriatric Depression
Scale (GDS) developed by Yesavage et al. (1983) into
Korean, after which it was modified and complemented by
Jung et al. (1997) in order to measure the severity of depression
in the elderly.
