The purpose of this study was to describe relations among mood
states, cognitive function, and the quality of life (QOL) for the
community-dwelling older people (N=167), and to identify any
differences in the states, the function, and the QOL according to
their socio-demographic variables. Data were collected through the
one-to-one interview with the structured questionnaires. There
were significant differences in mood state according to their gender
and marital status, but not their age and health status. For the
cognitive function, there were significant differences according to
their age, gender, educational level, marital status, regularly-taking
exercise, and health status. For the QOL, there were significant
differences their gender, educational level, marital status, regularlytaking
exercise, and health status. The QOL was significantly
correlated with the mood states and cognitive function. The
findings imply that nursing intervention programs that can enhance
the QOL for the older people should be emphasized upon changing
their mood states and cognitive function.
