Objective : To evaluate the cognitive perceptual performance in relation to the instrumental activities of daily living in Korean elderly women living in Seoul, Pundang, and Kwang-ju county.Method : To evaluate the cognitive perceptual performance, LOTCA-G battery was employed while IADL by Lawton and Brody was used to evaluate the instrumental activities of daily living. T-test, ANOVA, correlation analysis, and multiple regression analysis were used to ana-lyze the accumulated data.Results : The total cognitive perceptual performance score (LOTCA-G) and the total instrumental activities of daily living score (IADL) generally demonstrated a high correlation : (1) From observing the correlation of each items, the ability to use the telephone demonstrated a positive correlation with orientation, concentration, visuomotor organization, perception, memory, thinking operation and praxis (2) While shopping demonstrated a positive correlation with think-ing operation, visuomotor organization, orientation and memory (3) Food preparation demon-strated a positive correlation with orientation, thinking operation, visuomotor organization, con-centration, memory and praxis (4) While house keeping had a positive correlation with ori-entation, memory, visuomotor organization, thinking operation, concentration and perception (5) Laundry demonstrated a positive correlation with all of the items except visuomotor organization (6) While the mode of transportation demonstrated a positive correlation with all of the items including orientation and memory (7) Responsibility for one’s own medication demonstrated a positive correlation with orientation and thinking operation (8) The ability to handle finances demonstrated a positive correlation with orientation and all of the items.Conclusion : Cognitive perceptual performance was found to be significantly correlated with the instrumental activities of daily living skills. In particular, orientation and thinking operation, which are the items of cognitive perceptual performance affected the instrumental activities of daily living the most. Thus, orientation, perception, visuomotor organization, thinking operation, memory, praxis, concentration and cognitive perceptual performance need to improve not only so elderly women may live independently in the community but so as to offer them a high stand-ard of livin.
